Hurricane Lee is ‘growing in size’ with flood threat for New England: Live forecast

Hurricane Lee is “growing in size” and forecast to turn north on Thursday, increasing in forward speed, according to the National Weather Service (NWS).

Forecasters believe that Lee will make landfall in Nova Scotia, Canada as a tropical storm on Sunday, bringing winds and widespread flooding to large parts of New England - Rhode Island, eastern Massachusetts, southeastern New Hampshire and central and coastal Maine.

The slow-moving storm is currently 535 miles (860km) south of Bermuda, where a tropical storm watch was issued on Tuesday.

“Lee is very large hurricane. Hurricane-force winds extend outward up to 125miles (205km) from the center and tropical-storm-force winds extend outward up to 240miles (390 km),” NWS reported today.

Hazardous surf and rip current conditions are expected at beaches up and down the US East Coast and Atlantic Canada this week.

“Life-threatening” coastal conditions are also being experienced in parts of the Lesser Antilles, the British and US Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, and Bermuda.

Behind Lee is Hurricane Margot, the fifth hurricane of the 2023 season. Margot is tracking north for now, the NWS reported, but that the forecast beyond Friday was “highly uncertain”.

US sets record for billion-dollar weather disasters in a year — and there’s still 4 months to go

21:00 , Louise Boyle

The deadly firestorm in Hawaii and Hurricane Idalia’s surge helped push the United States to a record number of weather disasters that cost $1 billion or more in 2023. And there’s still four months to go on what’s looking more like a calendar of calamities.

The National Oceanic and Atmospheric Administration announced Monday that there have been 23 weather extreme events in America that cost at least $1 billion this year through August, eclipsing the year-long record total of 22 set in 2020. So far this year’s disasters have cost more than $57.6 billion and claimed at least 253 lives.

And NOAA’s count doesn’t yet include Tropical Storm Hilary’s damages in hitting California and a deep drought that has struck the South and Midwest because those costs are still to be totaled, said Adam Smith, the NOAA applied climatologist and economist who tracks the billion-dollar disasters.

What is Hurricane Lee’s ‘cone of uncertainty’?

20:30 , Louise Boyle

Hurricane Lee is tearing across the Atlantic bringing strong winds and dangerous currents to parts of the Caribbean, before it is expected to pivot and travel up the US East Coast, potentially making landfall in Nova Scotia, Canada on Sunday.

The National Hurricane Center graphic below shows the probable path of Hurricane Lee. Areas under a hurricane warning are marked in red; hurricane watch in pink; tropical storm warning in blue; and tropical storm watch in yellow. The orange circle shows the current position of the cyclone’s center.

However NHC tropical cyclone forecast tracks have room for error, the agency notes.

This uncertainty is conveyed by the track forecast “cone” - the solid white and stippled white areas in the graphic.

The solid white area depicts the track forecast uncertainty for days 1-3 of the forecast.

The stippled area depicts the uncertainty on days 4-5.

The entire five-day path of the center of the tropical cyclone will remain within the cone about 60-70 per cent of the time, according to historical data.

Bermuda Government issues warning

20:01 , Louise Boyle

The government of Bermuda warned citizens that Hurricane Lee “is a large storm and is a threat” on Wednesday morning.

“The closest point of approach to Bermuda within 72 hrs (3 days) is forecast to be 165 nm [nautical miles] to the west [at] 1am Fri, Sep 15, 2023,” officials wrote on X, formerly Twitter.

People were warned against swimming due to “life-threatening” rip currents and swells produced by the hurricane.

“Lastly Bermuda, again at all times, please keep safety at the forefront. As we know, serious storms by their very nature are unpredictable,” the message concluded.

Cyclone that devastated Libya is latest extreme event with some hallmarks of climate change

19:30 , Louise Boyle

The Mediterranean storm that dumped torrential rain on the Libyan coast, setting off flooding that’s believed to have killed thousands of people, is the latest extreme weather event to carry some of the hallmarks of climate change, scientists say.

Daniel — dubbed a “medicane” for its hurricane-like characteristics – drew enormous energy from extremely warm sea water. And a warmer atmosphere holds more water vapor that can fall as rain, experts said.

It’s difficult to attribute a single weather event to climate change, “but we know there are factors that could be at play” with storms like Daniel that make it more likely, said Kristen Corbosiero, an atmospheric scientist at the University at Albany.

Hurricane Lee could make things worse in already sodden New England

19:00 , Louise Boyle

Parts of Connecticut and Massachusetts were under a flash flood warning on Wednesday, with radar indicating storms and an expected rainfall rate of 2 to 4 inches (5-10 centimeters) an hour, the National Weather Service said. Additional rainfall amounts of 2 to 4 inches are possible in some areas.

Rain from Hurricane Lee didn’t contribute to the flooding earlier this week. But it could inundate parts of the coastal Northeast during the weekend, forecasters said. Lee is traveling north and could make landfall in Nova Scotia, Canada, possibly as a tropical storm, forecasters said.

Up to 300 people were evacuated by Tuesday morning in Leominster, about 40 miles (64 kilometers) northwest of Boston, Mayor Dean Mazzarella said. He said the city has not seen such widespread damage since a 1936 hurricane. Most buildings downtown flooded and some collapsed. Rail service also was disrupted.

Leominster’s director of emergency management, Arthur Elbthal, said two dams out of 24 in the city sustained damage but held. He said the city is reinforcing them.

Belk said a trained spotter near Leominster recorded 9.5 inches (24 centimeters) of rain. The record for rainfall in a single day in Massachusetts was set Aug. 18, 1955, when Tropical Storm Diane dropped just over 18 inches (nearly 46 centimeters) in Westfield, Belk said.

Healey said she’s keeping a close eye on the forecast and how Hurricane Lee may affect the state as she toured flood damage in North Attleborough, about 55 miles (89 kilometers) south of Leominster.

“It was really scary, the amount of water that fell in just a short amount of time and the incredible devastation that it caused,” Healey said, adding she had reached out to the Biden administration, the state’s congressional delegation and the Federal Emergency Management Agency for assistance.

New England braces for more rain after hourslong downpour left communities flooded and dams at risk

15:30 , Martha Mchardy

More heavy rain was in the forecast Wednesday in New England, where residents were cleaning up after downpours dropped nearly 10 inches (25 centimeters) of rain in six hours and flooded parts of Massachusetts and Rhode Island.

The rainfall was a “200-year event,” said Matthew Belk, a meteorologist with the National Weather Service in Boston. Two communities declared a state of emergency and officials ordered evacuations out of concern for a dam listed in poor condition.

Rain from Hurricane Lee didn’t contribute to Monday’s flooding but could inundate parts of the coastal Northeast during the weekend, forecasters said.

Lee likely to remain ‘large’ and ‘dangerous’ into the weekend, says National Hurricane Center

14:30 , Martha Mchardy

Hurricane Lee is likely to remain “large” and “dangerous” into the weekend, the National Hurricane Center has said.

“Slow weakening is forecast during the next few days, however Lee is likely to remain a large and dangerous hurricane into the weekend,” the Center said.

“Lee’s expected post-tropical transition will not diminish potential wind, rain and coastal flooding impacts in New England and Atlantic Canada due to the system’s broad wind field.”

Hurricane Lee is expected to weaken in upcoming days as it enters cooler waters but wind, rain and flooding are still expected in New England and Atlantic Canada.

Hurricane-force winds extend up to 115 miles (185 kilometers) from Lee’s center, and tropical-storm-force winds extend up to 240 miles (390 kilometers), the center reported.

Forecasters warned of dangerous surf and rip currents in Lesser Antilles, the British and U.S. Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda and parts of the U.S. southeast coast. The conditions were expected to spread to the U.S. East Coast and Atlantic Canada in upcoming days.

Hurricane Lee turns north on path that will take it past Bermuda as it aims for Atlantic Canada

14:00 , Martha Mchardy

Hurricane Lee began to spin away from the northern Caribbean on Wednesday as the Category 3 storm aimed for Atlantic Canada and left big waves in its wake.

The storm was located about 475 miles (765 kilometers) south-southwest of Bermuda in the morning. It had winds of up to 115 miles per hour (185 kilometers per hour) and was moving northwest at 6 mph (9 kph).

Lee was expected to eventually pass just west of Bermuda, prompting forecasters to issue a tropical storm watch for the island. Wind and heavy rainfall were expected to lash Bermuda starting late Wednesday or early Thursday, forecasters said.

Tropical storm conditions are expected in Bermuda ‘early tomorrow,’ the National Hurricane Center has said.

It comes as a tropical storm warning was issued for Bermuda and the US East Coast, with heavy rainfall expected throughout Thursday.

Bermuda and the US East Coast are bracing for “life-threatening” rip currents, the center said.

The National Hurricane Center also said the risk of wind, coastal flooding and rain has increased for portions of New England and Atlantic Canada due to Hurricane Lee.

On the forecast track, the center of Lee will pass west of Bermuda on Thursday before approaching the coast of New England or Atlantic Canada late this week.

The National Hurricane Center said early Wednesday morning that Lee is now a “very large hurricane” and is producing large swells which will impact parts of the western Atlantic all week.

Hurricane Lee swirls through open waters on a path to Atlantic Canada

13:00 , Martha Mchardy

Hurricane Lee whirled north of Puerto Rico on Tuesday as a Category 3 storm, with forecasters noting it would remain in open waters through this week while on a path to Atlantic Canada.

The storm was located 575 miles (925 kilometers) south of Bermuda. It had winds of up to 115 mph (185 kph) and was moving west-northwest at 7 mph (11 kph).

By Sunday, Lee was forecast to weaken into a tropical storm and likely make landfall in Nova Scotia, Canada, according to AccuWeather.

Dangerous surf and rip currents to continue affecting western Atlantic into the weekend

10:49 , Martha Mchardy

Dangerous surf and rip currents are expected to continue affecting areas around the western Atlantic into the weekend, the National Hurricane Center has said.

Portions of the northern Leeward Islands, the Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda, and most of the East Coast will be affected throughout much of the week.

It comes as a tropical storm warning has been issued for Bermuda and the US East Coast, with heavy rainfall expected throughout Thursday.

The National Hurricane Center said early Wednesday morning that Lee is now a “very large hurricane” and is producing large swells which will impact parts of the western Atlantic all week.

Hurricane Lee expected to weaken in upcoming days

10:30 , Martha Mchardy

Hurricane Lee is expected to weaken in upcoming days as it enters cooler waters, the National Hurricane Center has said.

“Despite the weakening that is forecast, keep in mind that the expanding wind field of Lee will produce impacts well away from the storm center,” the center said.

Lee was generating dangerous surf and rip currents for the Lesser Antilles, the British and U.S. Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, Bermuda and parts of the southeast U.S. coast. Those conditions were expected to soon spread to the U.S. East Coast.

“It remains too soon to know what level of additional impacts Lee might have along the northeastern U.S. coast and Atlantic Canada late this week and this weekend,” the National Hurricane Center said.

Libya flood: 10,000 missing, 1,500 bodies recovered after Storm Daniel sends wall of water through city of Derna

Wednesday 13 September 2023 00:50 , Louise Boyle

Emergency workers uncovered more than 1,500 bodies in the wreckage of Libya’s eastern city of Derna on Tuesday, and it was feared the toll could spiral with 10,000 people reported still missing after floodwaters smashed through dams and washed away entire neighborhoods of the city.

The startling death and devastation wreaked by Mediterranean storm Daniel pointed to the storm’s intensity, but also the vulnerability of a nation torn apart by chaos for more than a decade.

The country is divided by rival governments, one in the east, the other in the west, and the result has been neglect of infrastructure in many areas.

Outside help was only just starting to reach Derna on Tuesday, more than 36 hours after the disaster struck. The floods damaged or destroyed many access roads to the coastal city of some 89,000. (Associated Press)

Hurricane Lee: The latest update

Tuesday 12 September 2023 15:23 , Louise Boyle

The Category 3 system remains a slow-moving, major storm and is forecast to go through “additional strengthening” in the coming days in the warm Atlantic waters.

The hurricane is currently moving west-northwest near 7mph (11kph) before it turns north mid-week, passing west of Bermuda, according to the 5am (eastern time) update from the US National Hurricane Center (NHC).

Swells generated by Lee are causing life-threatening surf and rip currents in parts of the Lesser Antilles, the British and US Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, the Bahamas, and Bermuda, according to NHC.

The southeastern US coast is also facing these hazardous conditions which are expected to spread north along much of the US East Coast in the next couple of days.

Atlantic sees two simultaneous hurricanes as Margot strengthens

Tuesday 12 September 2023 15:00 , Joe Sommerlad

Hurricane Lee is expected to continue to gain strength as it cruises across the Atlantic Ocean, and just behind it is Hurricane Margot, which reached hurricane status on Monday night. Margot is forecast to go through further strengthening during the next 48 hours, the US National Hurricane Center said in its latest advisory.

The hurricane was located about 1,265 miles (2,035km) northwest of the Cape Verde Islands, packing maximum sustained winds of 75mph (120kph), the Miami-based forecaster said.

Margot became a Category 1 storm Monday afternoon and was expected to continue to intensify to become the fifth hurricane of the season. It was forecast to remain over open waters.

It’s unclear what path they will take in the coming days, and whether they will pose a threat to the East Coast.

But they could get close enough for a phenomenon called the Fujiwhara effect, in which two storms rotate around each other and spin in the same direction. The National Weather Service describes it as “an intense dance around their common center.”

The phenomenon occured with hurricanes Hilary and Irwin in the East Pacific in 2017.

‘Rapid intensification’ of storms likely to accelerate with warming waters

Tuesday 12 September 2023 12:00 , Alex Woodward

Hurricane Lee is in rare company. Only two recorded storms – Hurricane Wilma in 2005 and Hurricane Felix in 2007 – strengthened faster than Lee over a 24-hour period, as Lee developed from a Cat 1 to a Cat 5 last week before degrading into its current Cat 3 status.

The storm is predicted to continue to regain strength after slowing down over the weekend.

Brian McNoldy with the University of Miami told NBC News that the warm conditions in the Atlantic were ripe for the storm’s rapid intensification last week.

The “vertical wind shear was very low and the water temperature under it was very warm,” he said, adding that Lee “took full advantage of both.”

Last year, Hurricane Ian rapidly intensified over two separate periods before striking Florida. Hurricane Idalia recently strengthened from a Cat 1 to a Cat 4 within 24 hours.

“It’s a huge problem, and the past is not a good guide to what we should expect going forward,” Jeff Masters, a former hurricane scientist with the National Oceanic and Atmospheric Administration, told NBC.

Dangerous rip currents caused by Hurricane Lee begin to affect southeast US

Tuesday 12 September 2023 09:00 , Graig Graziosi

Forecasters have warned for days that Hurricane Lee could produce dangerous rip currents on the US east coast, and those predicitions have come to pass.

The National Hurricane Centre reported Monday morning that dangerous rip currents — which can drag swimmers out to sea — have begun in the southeastern US.

“Dangerous surf and rip currents have begun to affect portions of the southeastern U.S. coast, and these conditions are forecast to spread northward along much of the U.S. East Coast during the next couple of days,” the centre warned.

Swimmers in southeastern US states should consult their local weather information providers before heading out for a swim over the next few days.

2023 sets the record for number of billion-dollar climate disasters

Tuesday 12 September 2023 08:00 , Graig Graziosi

The NOAA has identified 23 seperate climate and weather disasters in 2023 that caused at least a billion dollars in damages, according to the agency.

Those events include Hurricane Idalia, which struck Florida’s western shoreline near Big Bend in late August, the devastating wildfire on Maui that killed more than 100 people, and a number of lesser reported but still highly damaging weather and climate disasters.

Severe storms, tornadoes, and hail blasted the Plains states in the spring, while California saw record breaking floods between January and March.

“There have been 23 confirmed weather and climate disaster events this year, each with losses exceeding $1bn. These disasters consisted of 18 severe storm events, two flooding events, one tropical cyclone, one winter storm and one wildfire event,” the NOAA reports. “For this year-to-date period, the first eight months of 2023 rank highest for disaster count, ahead of 2020 with 16 disasters. The total cost of these events exceeds $57.6bn, and they have resulted in 253 direct and indirect fatalities.”

Hurricane Lee: Latest National Hurricane Centre report says storm should begin to swing north by midweek

Tuesday 12 September 2023 04:00 , Graig Graziosi

Hurricane Lee continued churning in the Atlantic on Monday after reaching its peak as a Category 5 storm on Thursday.

The National Hurricane Centre reports that Hurricane Lee is producing maximum sustained winds of 120mph (195km/h) — a Category 3 hurricane — and is on a northwesterly trajectory moving at 7mph (11km/h).

The centre believes Hurricane Lee will continue taking a “slow” path toward the west-northwest over the next few days before turning gradually north by the middle of the week.

The storm is expected to pass well north of the Virgin Islands and Puerto Rico. It is currently approximately 340 miles (545km) north of the Northern Leeward Islands and approximately 650 miles (1045km) south-southeast of Bermuda.

We’re in the ‘peak’ of Atlantic hurricane season

Tuesday 12 September 2023 03:00 , Alex Woodward

Sunday’s climatological peak of the Atlantic hurricane season – with conditions ripe for tropical storms and hurricanes – saw considerable action, with a strengthening Category 3 hurricane and soon-to-be hurricane tracking closely together, followed by two brewing systems to their west.

The “peak” date typically sees ocean waters at their highest temperatures, peak intensity in the atmosphere to generate thunderstorms, and shearing winds that can suffocate storms declining to a minimum, which tropical waves that fuel storms in the summer continue well into September.

What happens when hurricanes ‘collide’?

Tuesday 12 September 2023 02:00 , Stuti Mishra

Tropical Storm Margot is expected to reach hurricane status on Monday, raising the prospect of two potentially major hurricanes spinning in the Atlantic simultaneously and in similar paths.

That phenomenon, when two storms rotate around each other and spin in the same direction, is called the Fujiwhara effect. The National Weather Service describes it as “an intense dance around their common center” and potentially combine into one major storm.

The rare phenomenon occured with hurricanes Hilary and Irwin in the East Pacific in 2017.

If one hurricane is stronger than the other, the smaller one will orbit it and eventually come crashing into its vortex to be absorbed, according to the NHC.

“Two storms closer in strength can gravitate towards each other until they reach a common point and merge, or merely spin each other around for a while before shooting off on their own paths,” the center explains.

Hurricane season, by the numbers

Tuesday 12 September 2023 01:00 , Alex Woodward

NOAA forecasts 12 to 17 total named storms this year, with five to nine of those storms turning into hurricanes, including up to four major hurricanes with winds of 111 mph or higher.

The season, which officially began on 1 June and will end on 30 November, already has produced 14 storms, including four hurricanes – theree of which were Category 3 or higher.

Nearly half of the world’s population was exposed to at least 30 days of extreme heat driven by the climate crisis between June and August, according to recently published research from Climate Central.

More than 3.8 billion people across the world suffered extreme temperatures for over a month, while “nearly every living human” – around 98 per cent of the world – was exposed to extreme heat at least once between June and August 2023, the report found.

The longest duration of extreme temperatures, approximately three months, was experienced by at least 1.5 billion people who were exposed to unusually high heat on each day over the period of June to August, the study says.

Hurricane Margot becomes fifth hurricane of the 20223 season

Monday 11 September 2023 22:50 , Graig Graziosi

The National Weather Service announced that Tropical Storm Margot had been upgraded to a full fledged hurricane on Monday afternoon.

Hurricane Margot is the fifth hurricane of the season, and formed not only during the peak of the season but in the immediate wake of Hurricane Lee, which is still churning through the Atlantic off the southeastern coast of the US.

‘Rapid intensification’ of storms likely to accelerate with warming waters

Monday 11 September 2023 20:30 , Alex Woodward

Hurricane Lee is in rare company. Only two recorded storms – Hurricane Wilma in 2005 and Hurricane Felix in 2007 – strengthened faster than Lee over a 24-hour period, as Lee developed from a Cat 1 to a Cat 5 last week before degrading into its current Cat 3 status.

The storm is predicted to continue to regain strength after slowing down over the weekend.

Brian McNoldy with the University of Miami told NBC News that the warm conditions in the Atlantic were ripe for the storm’s rapid intensification last week.

The “vertical wind shear was very low and the water temperature under it was very warm,” he said, adding that Lee “took full advantage of both.”

Last year, Hurricane Ian rapidly intensified over two separate periods before striking Florida. Hurricane Idalia recently strengthened from a Cat 1 to a Cat 4 within 24 hours.

“It’s a huge problem, and the past is not a good guide to what we should expect going forward,” Jeff Masters, a former hurricane scientist with the National Oceanic and Atmospheric Administration, told NBC.

Watch: Footage from inside the NOAA’s flight into Hurricane Lee

The NOAA sent a “hurricane hunter” aircraft into Hurricane Lee on Sunday night to gather data on the now Category 3 storm churning in the Atlantic.

The agency filmed a portion of the flight, which shows the researchers being jostled back and forth by the storm’s sustained 120mph winds.

Hurricane Lee is expected to remain a powerful hurricane until midweek, when forecasters believe it will begin to weaken.

2023 sets the record for number of billion-dollar climate disasters

Monday 11 September 2023 18:00 , Graig Graziosi

The NOAA has identified 23 seperate climate and weather disasters in 2023 that caused at least a billion dollars in damages, according to the agency.

Those events include Hurricane Idalia, which struck Florida’s western shoreline near Big Bend in late August, the devastating wildfire on Maui that killed more than 100 people, and a number of lesser reported but still highly damaging weather and climate disasters.

Severe storms, tornadoes, and hail blasted the Plains states in the spring, while California saw record breaking floods between January and March.

“There have been 23 confirmed weather and climate disaster events this year, each with losses exceeding $1bn. These disasters consisted of 18 severe storm events, two flooding events, one tropical cyclone, one winter storm and one wildfire event,” the NOAA reports. “For this year-to-date period, the first eight months of 2023 rank highest for disaster count, ahead of 2020 with 16 disasters. The total cost of these events exceeds $57.6bn, and they have resulted in 253 direct and indirect fatalities.”

We’re in the ‘peak’ of Atlantic hurricane season

Monday 11 September 2023 14:00 , Alex Woodward

Sunday’s climatological peak of the Atlantic hurricane season – with conditions ripe for tropical storms and hurricanes – saw considerable action, with a strengthening Category 3 hurricane and soon-to-be hurricane tracking closely together, followed by two brewing systems to their west.

The “peak” date typically sees ocean waters at their highest temperatures, peak intensity in the atmosphere to generate thunderstorms, and shearing winds that can suffocate storms declining to a minimum, which tropical waves that fuel storms in the summer continue well into September.
