MIAMI — Tropical Storm Bertha strengthened in the Gulf of Mexico early Tuesday as it drifted slowly toward the northern Gulf Coast, prompting tropical storm warnings and storm surge alerts across parts of the Florida Panhandle, Alabama and coastal Louisiana, while forecasters warned of heavy rainfall, coastal flooding and gusty winds over the coming days.
The U.S. National Hurricane Center said Bertha was located about 125 miles (205 km) south of Panama City, Florida, and about 200 miles (320 km) southeast of Mobile, Alabama, at 1 a.m. CDT. The storm had maximum sustained winds of 50 mph (85 kph) and was moving northwest at 2 mph. Forecasters said additional strengthening remained possible before the system turns westward along the northern Gulf Coast.
A tropical storm warning was in effect from the Alabama-Florida border westward to the Jefferson/Plaquemines Parish line in Louisiana. A storm surge watch covered the coast from the Alabama-Florida border to the mouth of the Mississippi River, while tropical storm watches extended farther west into Louisiana.
The National Hurricane Center warned that tropical storm conditions could begin affecting portions of the warning area later Tuesday into Wednesday. Storm surge of 2 to 4 feet (0.6 to 1.2 meters) above ground level was possible in some coastal locations if peak surge coincides with high tide, while heavy rainfall could trigger flash flooding in vulnerable areas. Isolated tornadoes were also possible, particularly across parts of the Florida Panhandle and Big Bend region.
Emergency officials in several Gulf Coast communities began distributing sandbags and urging residents in flood-prone areas to monitor forecasts and prepare for changing conditions. Authorities advised mariners to remain in port where warnings were in effect and cautioned against unnecessary travel in areas susceptible to flooding.
Forecast uncertainty remained centered on Bertha's exact track and strength later in the week. The National Weather Service said the storm was expected to move near the Louisiana coast before potentially approaching southeast Texas, although increasing wind shear and dry air could weaken the system as it progresses westward. Officials emphasized that even a weaker tropical cyclone could produce dangerous rainfall, rough surf and localized coastal flooding.
The National Hurricane Center said residents along the northern Gulf Coast should continue monitoring official forecasts and heed instructions from local emergency management agencies as Bertha approaches the region.
