Florida’s weather outlook for the July 4th holiday weekend is turning uncertain, as meteorologists warn that a low-pressure system could form off the southeastern Atlantic coast or the Gulf of Mexico, potentially developing into a tropical depression just in time to impact holiday celebrations.
The National Hurricane Center (NHC) reported on Sunday that it is closely monitoring this system, which currently has a 20% chance of tropical development over the next seven days.
According to an official bulletin, “by late this week and into the weekend, a low-pressure area could form from the remnants of a front near or along the southeastern U.S. coast, in the Atlantic or Gulf waters.”
A gradual tropical or subtropical development is possible as the system drifts slowly along the U.S. coastline, raising concerns for outdoor events planned throughout Florida and the Southeast.
Alex DaSilva, lead hurricane forecaster for AccuWeather, explained that both the Gulf of Mexico and the Atlantic waters off the Southeast are typical breeding grounds for early July systems. He noted that “a cold front will dip into the region by late next week and could act as a catalyst for thunderstorm development, either in the eastern Gulf or just off the Southeast coast.”
Forecasters are focusing on this area of interest because it could disrupt weekend plans as rain and thunderstorms are expected to increase in coverage and intensity by early July.
“A pattern shift will occur shortly after peak heat hits the southeastern interior, setting the stage for more widespread rain and thunderstorms into early July,” said Alex Sosnowski, senior meteorologist at AccuWeather.
Parts of the Florida Peninsula are likely to receive much-needed rainfall in the coming days—though vacationers in the Sunshine State may not welcome the timing.
So far, only one named storm—Andrea—has developed in the Atlantic hurricane basin this season, and it lasted less than 24 hours earlier last week. If the new system strengthens early next month, the next storm name on the list is Barry.
DaSilva added that wind shear, a factor that usually hinders tropical storm formation, is expected to be relatively low in the projected area, while sea surface temperatures in the Gulf remain above average for this time of year.
“If anything develops, heavy rainfall will likely be the main concern,” he said.
Torrential downpours could dump over an inch of rain in a short time across some parts of the region. Despite the sandy soil in Florida and along the Gulf Coast, storm drains may temporarily become overwhelmed, leading to road and highway flooding.
Waterspouts near the coast could also occur, especially when combined with intense rainfall, which could spoil beach days and boating activities, according to AccuWeather.
Whether the system evolves into a more organized tropical storm remains uncertain, but stronger winds, coastal erosion, and tidal flooding would only become concerns if that scenario unfolds during the July 4 weekend.
Tropical depression forms in the Gulf of Mexico
Meanwhile, the second tropical depression of the 2025 Atlantic hurricane season has developed in the Gulf of Mexico, prompting a tropical storm warning from Boca de Catan to Tecolutla, according to the NHC.
The system is producing maximum sustained winds of 35 mph (55 km/h), with higher gusts, and may strengthen slightly before making landfall along Mexico’s eastern coast.
By Sunday afternoon, the system had officially become the second named storm of the season, now called Barry.
The NHC forecasts that Barry will make landfall over eastern Mexico later Sunday or Sunday night, bringing torrential rains to a large portion of the region.
