Tropical Storm Bertha formed Monday evening in the Gulf of Mexico, south of the Florida Panhandle, and is expected to strengthen as it drifts slowly toward densely populated coastal areas, the Miami-based National Hurricane Center (NHC) has warned. The storm's centre was located approximately 110 miles (180 kilometres) south of Panama City, Florida, with maximum sustained winds of around 40 mph (65 kph). Although moving erratically and slowly — at roughly 3 mph (6 kph) — Bertha is forecast to track westward along the northern Gulf Coast before making landfall in south-eastern Louisiana on Wednesday.
Authorities have issued a storm surge watch stretching from the Alabama-Florida border westward to the mouth of the Mississippi River in Louisiana, warning of life-threatening coastal flooding within the next 48 hours. Water levels could rise by 2 to 4 feet (60 to 120 centimetres) along portions of that stretch, with surge of 1 to 3 feet possible across parts of coastal Louisiana and Florida, including the low-lying shores of Lake Pontchartrain — a large brackish lake just north of New Orleans. A tropical storm watch extends from the Mississippi-Alabama border to the line separating Louisiana's Jefferson and Plaquemines parishes. Forecasters cautioned that additional watches for further sections of the Gulf Coast may be required in the coming hours.
Beyond storm surge, Bertha is expected to produce widespread rainfall of 2 to 5 inches (5 to 12 centimetres), with isolated totals of up to 8 inches possible through Friday from western Florida to the middle Texas coast. That raises the risk of flash flooding across a broad swath of the region. An isolated tornado or two is also possible over Florida's Big Bend region, the curved section of coastline where the Florida Peninsula meets the Panhandle. Bertha is the second named storm of the 2026 Atlantic hurricane season, following Tropical Storm Arthur, which brought heavy rain to the south-eastern United States last month.
Separately, Hurricane Fausto formed in the eastern Pacific on Monday night, far from Mexico's Baja California Peninsula — the long, narrow strip of land that extends southward from the US state of California. With sustained winds of 75 mph (120 kph) and moving west-northwest, Fausto poses no threat to land, though ocean swells it generates could produce dangerous surf and rip current conditions along the Baja California coast.
The unfolding situation along the Gulf Coast underscores the vulnerability of low-lying communities in states such as Louisiana, Mississippi, and Alabama, which sit at or near sea level and have historically borne the brunt of Atlantic storm systems. Residents from western Florida to Texas have been urged by forecasters to closely monitor Bertha's progress in the coming days as the storm's erratic track makes precise landfall predictions difficult.
