Tallahassee, Fla. — The system now identified as Tropical Storm Bertha is expected to remain a low-grade threat to Florida’s Gulf Coast this week. According to meteorologist Ryan Truchelut of WeatherTiger, the storm's impacts will be primarily limited to periodic rainbands and minor coastal flooding along the Central and Eastern Gulf Coasts through midweek. While the system has strengthened into a tropical storm with maximum sustained winds of 40 mph near Panama City, it is not forecasted to become a major hazard for residents.
Rainfall Forecasts for North Florida
Bertha is currently drifting slowly in the northeastern Gulf of Mexico. The National Hurricane Center (NHC) predicts that the storm will peak with modest winds by early Wednesday before weakening further due to northerly wind shear and dry air. This atmospheric environment prevents the establishment of a deep convection core, meaning heavy rain pulses will occur mostly in bands away from the center.
Residents along the immediate coast from Cedar Key to Mobile can expect 2-4 inches of rainfall. Inland areas of North Florida should anticipate an additional 1-2 inches through the end of the week. As Bertha moves toward the western Panhandle or points west, outer bands are already intermittently sweeping across the Gulf Coast. Precipitation will be minimal in areas west of New Orleans due to increasing shear.
Coastal Surge and Wind Risks
Beyond rain, there is a risk for low-level storm surge and wind gusts. A Storm Surge Watch is currently in effect from eastern Louisiana to the Florida-Alabama border. Southeast-facing shores may see tides increase by 2-3 feet midweek due to an extended offshore fetch of southeast winds.
Coastal flooding reaching up to 1-2 feet above typical daily high tide marks is probable for the Panhandle and Big Bend regions. While widespread wind damage is not expected, peak gusts in the low-end tropical storm range (40-50 mph) are possible in squally bands along the immediate coast from Cedar Key to Mobile, NYT reported.
Local Safety Precautions
Tornadoes remain a minor risk. Although Bertha is weak, quick spin-ups can occur in outer bands of tropical systems. Residents are advised to keep National Weather Service warnings active on their devices along the Central and Eastern Gulf Coast.
Overall, conditions will likely resemble a normal summer mix of sun and rain away from the immediate coast. However, driving conditions may become inclement in heavier rainbands. Truchelut advises residents to stay informed through the week to avoid unnecessary risks as Bertha approaches Florida’s shoreline.
