Tracking the Tropics: August 22, 2025
FOX 13 meteorologist Nash Rhodes has the latest on the tropics.
TAMPA, Fla. - As Erin moves away from the United States, the National Hurricane Center is watching two waves in the tropics for possible development – including at least one that could form this weekend.
Activity in the tropics
The NHC is giving an area of disorganized showers and thunderstorms east-northeast of the Leeward Islands, dubbed Invest 90L, an 80% chance of development in the next two days and a 90% chance in the next seven days.
FOX 13 meteorologists say the system should curve in the Atlantic and miss the U.S.
Another tropical wave west-southwest of the Cabo Verde Islands, dubbed Invest 99L, has a 30% chance of development in the next two days and a 40% chance in the next seven days, according to the NHC.
Meteorologist Nash Rhodes said a short-lived tropical depression could form from this disturbance in the short-term. It could could enter into a favorable environment for development later this weekend into the start of next week – something the Windward islands will need to keep an eye on over the next few days, according to Rhodes.
A third disturbance the NHC was monitoring in the central Atlantic has fizzled.
The next name on this year’s Atlantic storm list is Fernand.
Hurricane Erin
As of 5 p.m. on Friday, Erin was located at 40.0N and 59.7W with maximum sustained winds of 90 mph.
The storm weakened Friday and is no longer considered a hurricane. It's now moving east-northeast at 33 mph, turning away from the U.S.
The NHC says Erin will continue bringing life-threatening surf and rip currents along the beaches of the Bahamas, much of the east coast of the U.S., and Atlantic Canada over the next few days.
Tampa Bay area forecast
FOX 13 Meteorologist Jim Weber says rain chances are slowly increasing after Erin pulled moisture away from the Tampa Bay area on Wednesday and Thursday.
Weber says some showers and thunderstorms will move inland on Friday with rain coverage at 40%. Rain chances will go up to about 50% this weekend.
