Tropical Storm Bertha formed in the Gulf of Mexico after strengthening from a tropical depression and then stalled near the northern Gulf Coast, where it kept states on alert for flooding rain and storm surge. Late on July 20, the system was barely moving and had maximum sustained winds of 40 mph.
The National Hurricane Center said Bertha was about 140 miles south of Panama City, Florida, and roughly 215 miles southeast of Mobile, Alabama, putting its slow, stubborn motion at the center of the threat. That kind of movement matters because a sluggish storm can dump the same bands of rain over the same places for hours, instead of sweeping them inland and away.
Forecasters expected 2 to 4 inches of rain across a broad swath of the Gulf Coast, with pockets of as much as 8 inches where the heaviest bands set up. Those totals can turn dangerous fast in cities, where pavement sends water racing into streets and low spots, and they also raise the risk of flash flooding along the coast from Florida through Alabama, Misisipi and Luisiana.
AccuWeather said the danger would climb if the strongest rain shifted west and reached the hilly terrain of central Texas, where runoff can accelerate as water moves downhill. Alex DaSilva said the same rain could help ease drought in parts of the Panhandle of Florida, but dry, hardened soils there would push water off the surface instead of soaking it up, making flash flooding more likely even as some areas badly need the moisture.
The storm surge watch stretches from the Alabama-Florida border to the mouth of the Mississippi River, a sign that coastal flooding is part of the threat, not just the rain. Bertha is the second named storm of the 2026 Atlantic hurricane season, after Arthur formed about a month earlier, and it is a reminder that a quieter season can still produce a dangerous strike when one system slows near land.
For now, the key question is not whether Bertha will matter, but where the heaviest rain bands will lock in next. The National Hurricane Center said the storm could strengthen slightly as it drifts slowly near or along the Gulf Coast, and residents across the coast north of the Gulf are being urged to keep following official advisories.
