Potential Gulf Low May Spawn Tropical Storm Bertha, Bringing Heavy Rain to Florida

Core Event: Possible Gulf Low-Pressure Development
The National Hurricane Center (NHC) has highlighted an area of low pressure expected to form in the northeastern Gulf of Mexico this weekend. Forecast guidance gives the disturbance a 20 percent chance of developing into a tropical depression or storm within the next seven days. If it reaches sustained winds of 39 mph, it would be named Bertha, the second named system of the 2026 Atlantic hurricane season. The system is projected to drift slowly northeastward, bringing moisture across northern and central Florida and potentially moving toward the southeastern U.S. coast early next week.
Background & Context: Seasonal Outlook and Model Discrepancies
July marks the early portion of the Atlantic hurricane season, a period when “homegrown” threats—low-pressure areas that break off from lingering frontal boundaries—often develop close to the U.S. coastline. Strong El Niño conditions are expected to suppress activity, and the Colorado State University (CSU) seasonal forecast has been lowered to nine named storms for the remainder of 2026. Nevertheless, exceptionally warm sea-surface temperatures (upper 80s °F, 2–4 °F above historic July averages) create localized pockets of favorable energy.
Model consensus is mixed. The European (EURO) model shows higher confidence in a Gulf low forming, while the U.S. Global Forecast System (GFS) assigns lower confidence. Some outlets note a 0 percent chance of development over the next 48 hours, contrasting with the overall 20 percent seven-day probability.
Data & Statistics: Probabilities, Sea-Surface Temperatures, Drought
- Development odds: 20 % (NHC 7-day outlook); 0 % (first 48 h) per several forecasts.
- Sea-surface temperatures: upper 80s °F in the northeastern Gulf, above average for mid-July.
- Drought: Extreme drought persists across the Big Bend, Gainesville, and Tampa Bay regions, though overall coverage is shrinking.
- Expected rainfall: Model ensembles suggest 4–6 inches along the Gulf Coast, with 3 inches more widespread inland.
Why It Matters: Rainfall, Flood Risk, and Seasonal Forecasts
Even without tropical cyclogenesis, the low-pressure system is expected to generate “locally heavy rain” that could alleviate drought but also trigger flash flooding in urban areas of northern and central Florida. The NHC notes that any development would likely remain a rainmaker rather than a major wind threat, yet the combination of warm water and lingering moisture could produce brief severe storms or tornadoes. NOAA’s preseason outlook predicts a below-normal season (8–14 named storms), underscoring that a single storm can still cause significant impacts.
Official Statements & Responses
- The NHC’s tropical weather outlook: “An area of low pressure is expected to form…slow development…possible while it moves slowly northeastward over the northeastern Gulf.”
- NOAA’s seasonal forecast: “Below-normal 2026 Atlantic hurricane season, with 8–14 named storms expected.”
- CSU’s revised projection: “Nine named storms, including four hurricanes and one major hurricane, are anticipated due to strong El Niño-driven wind shear.”
Criticism & Opposition
Meteorologists highlight model uncertainty. FOX 13’s Jim Weber warned that “we are close to 7.50 inches below average on our rainfall in Tampa for the year,” suggesting that any rain is welcome but also emphasizing the limited confidence in storm development. The GFS’s lower probability contrasts with the EURO model’s higher confidence, prompting calls for cautious public messaging.
Conflicting Reports & Gaps
Sources differ on immediate threat levels: CBS News Miami reports a 0 % chance in the next 48 hours, while Weather.com and multiple local stations maintain a 20 % seven-day chance. No official tropical-storm watch or warning has been issued, and the exact track remains uncertain, leaving a gap in precise impact forecasts for coastal counties.

- “At a minimum, this will be a rainmaker for Florida,” — Matt Devitt, Florida meteorologist
- “ Homegrown systems develop much closer to land—often in the Gulf or near the Southeast.” — Alexander Duffus, AccuWeather meteorologist
- “So far, we believe the chance of a tropical depression or storm forming in this area is low, but probably represents the best chance for tropical development throughout the Atlantic basin prior to the end of July,” — Alex DaSilva, AccuWeather Lead Hurricane Expert
- “Way down the line, if anything remains of the disturbance, it could find new life in the subtropical Atlantic, but there is a long way to go,” — FOX Forecast Center
- “If this potential system were to develop, it would receive the name Bertha.” — CBS News Miami NEXT Weather team
What’s Next
The NHC will issue its next advisory at 2 p.m. ET. Forecast models will be monitored for any shift in development odds, and residents of northern Florida, the Gulf Coast, and the Southeast are advised to stay informed of updated rain forecasts and potential flash-flood advisories.
