Tropical Storm Bertha spun up quickly Monday night just off Florida’s Gulf coast, and by Tuesday morning it was already prompting watches and warnings across a broad stretch of the northern Gulf region.
Forecasters are keeping a close eye on the system as it drifts slowly northwest, with the potential for heavy rain, gusty winds, and dangerous storm surge that could hit hardest in low-lying parts of Louisiana.
As of early Tuesday, the storm was centered about 110 miles south-southwest of Panama City and roughly 170 miles southeast of Mobile, Alabama. It was moving at a leisurely 5 mph with maximum sustained winds around 50 mph. While not a particularly fierce storm at the moment, its slow pace means it could linger and unload plenty of moisture on coastal communities.
Seven counties in Florida’s Panhandle — Bay, Escambia, Franklin, Gulf, Okaloosa, Santa Rosa, and Walton — are under a tropical storm watch. Farther west, a tropical storm warning stretches from the Florida-Alabama line all the way to the border of Jefferson and Plaquemines parishes in Louisiana. Storm surge watches are also in place for vulnerable shorelines from the Alabama-Florida border down toward the mouth of the Mississippi River.
The biggest concern right now is flooding. The National Hurricane Center is calling for 2 to 4 inches of rain across much of the Gulf Coast from western Florida into southern Louisiana, with some spots possibly seeing up to 6 inches through Thursday. Flash flooding could become an issue through Friday, particularly in low-lying areas north of Fort Myers and along the broader coastline.
Storm surge is another worry. Parts of the coast from the Mississippi River mouth over to the Alabama-Florida border could see 2 to 4 feet of water rise, while other stretches of Florida’s Big Bend region and Louisiana’s Lake Pontchartrain area might experience 1 to 3 feet. Outer bands of the storm are already starting to bring heavier rain and rough seas to North Florida and the Panhandle.
How strong Bertha ultimately gets will depend heavily on its exact path. If it stays closer to shore, it may not have as much time over the warm Gulf waters to intensify.
But a track that allows it to meander over open water could let it strengthen into a high-end tropical storm or even a minimal hurricane, according to some forecasts. Dry air and unfavorable winds aloft are expected to limit dramatic growth, though some modest strengthening is still possible in the short term.
Fortunately for folks in South Florida, the storm is staying far enough north and west that no direct impacts are expected there. Most of the heavier rain and wind should fall south of the storm’s center as it hugs the northern Gulf coast over the coming days.
This early-season activity comes as hurricane researchers at Colorado State University have dialed back their expectations for the overall 2026 Atlantic season, citing the influence of a strong El Niño that tends to create wind shear hostile to developing storms. They’re now predicting just nine named storms, four of which may become hurricanes, with only one major. The next system in line would be named Cristobal.
For now, residents along the northern Gulf should stay alert, especially in flood-prone areas. Even a modest tropical storm can cause significant problems when it moves slowly and brings prolonged rainfall and surge.
Officials are already urging people to monitor updates and prepare for potential disruptions through the middle of the week.
