Aftermath of rain, floods impacted Lower Hudson Valley

Storms that rolled through the Hudson Valley overnight Thursday and intensified Friday morning impacted residents and snarled travel throughout Friday.

Where is the flooding, traffic worst?

The storm is expected to continue into the weekend with a coastal flood advisory in place for the region through 11 a.m. Sunday.

Parts of the New York State Thruway, Bronx River Parkway, Hutchinson River Parkway, Saw Mill Parkway and the Playland Parkway were partially closed Friday afternoon due to flooding.

The Thruway Authority reported backed up traffic on the Gov. Mario M. Cuomo Bridge and stop and go traffic from Exit 14 in Spring Valley to Exit 7 in Ardsley and from Exit 10 in Nyack to Exit 4 by the Cross County Parkway in Yonkers early Friday afternoon. New York State Police said off-ramps on the Saw Mill River Parkway north and southbound at Exit 7A and southbound at Exit 8A are closed until further notice.

The National Weather Service advised commuters to stay off the roads this weekend. Gov. Hochul spoke on 1010 WINS Friday morning, warning New Yorkers to turn around if they encounter flooded roads.

"It could be dangerous," she said. "We've had circumstances as recently as this summer where vehicles were swept away. And also in our homes, we've had literally houses washed away. So I just wanted people to know we're preparing."

Is public transportation affected by the floods?

The Hudson, Harlem and New Haven lines on the Metro North Railroad are all suspended between the Bronx and Grand Central Terminal because of flooding on the tracks. MTA CEO Janno Lieber said in a news conference that about half of the subway system in New York City is partially or fully suspended. He said the MTA is actively trying to get lines back in service but commuters should use MyMTA and TrainTime to check which lines are active or closed.

John F. Kennedy and LaGuardia Airports reported flight delays and traffic around terminals around 11 a.m. on Friday. Terminal A at LaGuardia Airport is closed until further notice. The airports say they recommend travelers check their flight status before arriving at their terminals.

What's the forecast for the rest of the weekend?

Gov. Kathy Hochul issued a state of emergency Friday morning after severe storms rolled into the tri-state area.

States of emergency were also declared in Westchester County, the cities of Yonkers, New Rochelle and Mount Vernon and also New York City.

The National Weather Service issued a flash flood warning for northern Westchester County until 5:30 p.m. Friday. It estimated a total of three to five inches of rain Friday, potentially up to seven inches in localized areas, and a 70% chance of flash floods. Moderate flooding was reported in areas like Ossining, Peekskill, Haverstraw, Nanuet, Mount Kisco and Mahopac.

Saturday's forecast shows rain likely before 9 a.m. then a chance of showers likely between 9 a.m. and 3 p.m. The rest of the day is mostly cloudy with a high of 66. Chance of precipitation is 70%, but with new precipitation amounts between a tenth and a quarter of an inch.

Hudson Valley experiences historic rains all summer

The storms started in the Hudson Valley around 2 a.m. Friday, according to the National Weather Service. The intensity of the storms continued throughout the morning. The National Weather Service issued a flash flood warning Friday from 8:47 a.m. until 11:45 a.m. and issued a general flood advisory around 9:20 a.m. through 6 a.m. Saturday.

The severe weather is a continuation of historic storms and rainfall records in the region that began earlier in June and lasted through the summer, causing almost $81 million in damage according to Sen. Kirsten Gillibrand (D-NY).
