The system now identified as Tropical Storm Bertha is expected to remain a low-grade threat to Florida, with impacts primarily limited to periodic rainbands and minor coastal flooding along the Gulf Coast. According to an analysis by Dr. Ryan Truchelut of WeatherTiger, updated on July 20, 2026, the storm’s loose structure and marginal conditions for intensification suggest it will not develop into a significant hazard. Tropical Storm Watches are currently in effect for parts of the Florida Panhandle and Louisiana as the system drifts slowly through the northeastern Gulf.
Storm Trajectory and Intensity
As of Monday evening, the National Hurricane Center located Bertha’s center of circulation approximately 120 miles south of Panama City. The storm is characterized by maximum sustained winds of 40 mph, concentrated mainly in rainbands on its southern side. While the system has moved erratically since late Sunday, a slow northwest drift is resuming. Forecasts indicate that Bertha should peak early Wednesday with modest maximum sustained winds of 50 mph.
"With its loose structure and marginal support for further intensification, Bertha's impacts should be mostly limited to periodic rainbands along the Central and Eastern Gulf Coast through midweek," wrote Dr. Truchelut in his latest update.
Rainfall Expectations Across North Florida
Bertha is predominantly a "rainmaker" rather than a severe wind event. Northerly shear of 20 knots and mid-level dry air are preventing the establishment of deep convection near the storm's core, keeping most thunderstorm activity over water or in bands well-removed from the center. Outer bands have already begun intermittently sweeping the Florida Gulf Coast from Panama City south to the Tampa Bay area.
Residents can expect rain totals of 2 to 4 inches along the immediate coast from Cedar Key to Mobile, as well as in Southeast Louisiana. An additional 1 to 2 inches are anticipated for inland North Florida through the end of the week. West of the New Orleans area, precipitation will be minimal due to increasing shear, even if the storm track extends that far west.
Coastal Surge and Safety Precautions
An extended offshore fetch of southeast winds ranging from 20 to 30 knots is causing an increase in tides along the Central Gulf and Panhandle coasts. A Storm Surge Watch remains in effect for eastern Louisiana to the Florida-Alabama border, where a surge of 2 to 3 feet is possible midweek. Coastal flooding reaching up to 1 to 2 feet above typical daily high tide marks is probable in the Panhandle and Big Bend regions.
While winds are not considered a major hazard from Bertha, peak gusts of low-end tropical storm force (40-50 mph) may occur in squally bands along the immediate coast. Tornadoes remain an isolated risk within outer bands, but residents are advised to stay alert for National Weather Service warnings. Overall, conditions away from the immediate coast will likely resemble a normal summer mix of sun and rain.
