Tropical storm warning issued for parts of Florida as Potential Tropical Cyclone 1 moves toward Gulf

A tropical system — now known as Potential Tropical Cyclone One — gathering strength near the Yucatan Peninsula may become the first tropical storm of the 2022 Atlantic hurricane season as it heads toward Florida, according to the National Hurricane Center.

The Hurricane Center late Thursday night issued a tropical storm warning for portions of the Florida peninsula and the Florida Keys. Heavy rainfall is expected to spread over portions of Cuba, southern Florida and the Florida Keys with possible flooding on Friday and Saturday, according to the 11 p.m. ET advisory.

In its 5 p.m. advisory Thursday, the Hurricane Center issued a tropical storm watch for most of Florida's peninsula, including the state's east and west coasts, Florida Keys, Lake Okeechobee and Florida Bay. A tropical storm watch also was issued for portions of Cuba and the northwestern Bahamas.

The system, which has maximum sustained winds of 35 mph, is expected to become a tropical depression late Thursday night or on Friday and a tropical storm late Friday or Friday night as it moves northeast over the Gulf of Mexico, according to the Hurricane Center.

If sustained winds strengthen to 39 mph, it would become Tropical Storm Alex, the first name on this year's list of storm names for the Atlantic basin.

Regardless of development, the system could bring flooding rains across South Florida on Friday and Saturday, with some areas seeing 8 to 12 inches of rain. AccuWeather forecasters are predicting up to 20 inches in some areas.

Tropical storm warning issued for Potential Tropical Cyclone One

A tropical storm warning is in effect for:

  • West coast of Florida south of Englewood to Card Sound Bridge

  • Florida Keys including the Dry Tortugas

  • Florida Bay

A tropical storm warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours.

Tropical Storm Watch issued for Potential Tropical Cyclone One

A tropical storm watch is in effect for:

  • West coast of Florida from south of the Middle of Longboat Key to Englewood

  • East coast of Florida south of the Volusia/Brevard County Line to Card Sound Bridge

  • Lake Okeechobee

  • Cuban provinces of Matanzas, Mayabeque, Havana, Artemisa, Pinar del Rio, and the Isle of Youth

Tropical Storm Alex, tropical depression has high chance to develop

  • Formation chance through 48 hours: high, 90 percent.

  • Formation chance through 5 days: high, 90 percent.

At this time, AccuWeather meteorologists expect the tropical rainstorm to become a tropical depression over the southeastern Gulf of Mexico on Friday, prior to reaching the Florida Keys and the southern part of Florida Friday night and Saturday.

The system is likely to become a tropical storm while crossing Florida or perhaps just east of Florida.

There is a chance that if wind shear drops off quickly, a faster ramp-up to a tropical storm can occur, perhaps before the system reaches Florida.

What could be the impact of the tropical system on Florida?

Flash floods are possible as a tropical system moves across Florida.
Flash floods are possible as a tropical system moves across Florida.

The budding storm is expected to slice across Florida with torrential rain and produce building seas and rough surf in the region.

Regardless of development, areas of heavy rainfall are likely across portions of the Yucatan Peninsula and western Cuba during the next day or so, spreading across southern and central Florida and the Florida Keys Friday and Friday night, and the northwestern Bahamas on Saturday.

These heavy rains could cause scattered to numerous flash floods across South Florida and the Florida Keys.

When could the tropical system affect Florida?

As the storm moves northeast, flooding rains will begin to impact South Florida as early as Friday, according to AccuWeather.

As the storm moves into Florida, it will bring a large swath of torrential rains from the Keys to the southern and central parts of the state. The heaviest rain will likely occur in South Florida from Friday through Saturday night, with AccuWeather Local StormMax™ predicting up to 20 inches.

Regardless of whether the system becomes a tropical depression or tropical storm, it will approach Florida with drenching downpours and gusty thunderstorms from Friday to Saturday.

What other impact could the storm bring to Florida?

"There is also the potential for a few tornadoes and waterspouts as the system crosses the Florida Peninsula or passes just to the south of Florida," AccuWeather Senior Meteorologist Brett Anderson said.

In addition to torrential downpours and the likelihood of urban flooding, building seas and surf will occur around southern and central parts of Florida and the northern Bahamas.
