Hurricane Tammy pounding the Leeward Islands. See the latest spaghetti models
Hurricane Tammy is bringing strong winds and heavy rains across the Leeward Islands as the center moved very close to Antigua.
Tammy is a Category 1 hurricane with maximum sustained winds of 85 mph, according to the most recent advisory from the National Hurricane Center.
The NHC is also tracking a system in the southwestern Caribbean that has a low chance of developing.
The center of Tammy will move near or over portions of the Leeward Islands through tonight, and then move north of the northern Leeward Islands on Sunday.
Hurricane warnings and watches, along with tropical storm watches and warnings, have been issued for areas in Tammy's path.
Tammy is threatening the Lesser Antilles with downpours, flooding, rip currents and damaging winds, according to AccuWeather.
"The heavy rain and strong winds can bring damage to the islands, especially to weakened structures," AccuWeather Senior Meteorologist Dan Pydynwoski said. "There can also be power outages and downed trees and power lines."
The National Hurricane Center predicts Tammy could see sustained winds up to 100 mph within the by Monday morning, which would make it a Category 2 hurricane.
AccuWeather expects the storm will stay east of the mainland United States and Bermuda as the winds gradually weaken next week.

The Atlantic list of storm names for 2023 is down to just two: Vince and Whitney. Hurricane season doesn't end until Nov. 30, although storms can and do form any time.
Here are the latest details on Tammy, according to the NHC's 5 p.m. advisory.
Where is Hurricane Tammy?
Special note on the NHC cone: The forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time.
Location: 35 miles east-southeast of Antigua; 1,493 miles southeast of West Palm Beach
Maximum sustained winds: 85 mph
Movement: North-northwest at 10 mph
Minimum central pressure: 988 mb
At 5 p.m., the center of Hurricane Tammy was located near latitude 17.0 North, longitude 61.3 West. Tammy is moving toward the north-northwest near 10 mph, and this general motion is expected through Sunday, followed by a turn toward the north on Monday.
On the forecast track, the center of Tammy will move near or over portions of the Leeward Islands through early Sunday, then move north of the northern Leeward Islands by Sunday afternoon.
Maximum sustained winds are near 85 mph with higher gusts. Slow strengthening is possible over the next few days.
Hurricane-force winds extend outward up to 25 miles from the center, and tropical storm-force winds extend outward up to 125 miles.
The minimum central pressure based on data collected from the Air Force and NOAA Hurricane Hunters is 988 millibars.
Anything greater than 979 mb is one indicator a storm could cause minimal damage. According to the NHC, the minimum central pressure of a storm is not necessarily a hazard, but it could indicate whether a storm will intensify in the future. Strengthening usually follows a drop in pressure, and a weakening usually follows an increase in pressure.
