.SHORT TERM AND Long Term (Wednesday through Monday) Issued at 145am EDT Tuesday July 15 2025

Tropical disturbance will have moved into the eastern or northeastern Gulf by Wednesday morning. Models are in good agreement with ridging to the north over the southeast US to keep the disturbance on a general west or west-northwest movement to the north central Gulf coast Thursday. Models disagree on if the disturbance will develop, and if so, should remain on the weaker side. Regardless of development, rain chances will be at its highest (70% north to 90% south) Wednesday and Thursday as PWATs (Precipitable Waters) will be in excess of 2 inches and closer to 2.2 inches along the coast. With the higher rain chances and expected cloud cover, highs through late week will be slightly cooler with readings back into the lower 90s which will bring heat indices down below heat advisory criteria. As the disturbance moves by, an uptick in winds over the Gulf waters will occur as well as a high risk of rip currents along all area beaches into the weekend.

Speaking of the weekend, mid level ridging builds over the Gulf and southeast US with elevated rain chances into early next week as tropical moisture lingers and highs returning back to the mid to upper 90s. Heat advisories may be returning later this weekend.

Marine
Issued at 145am EDT Tuesday July 15 2025

Generally light north to northeast winds today will give way to increasing south to southeast winds Wednesday and Thursday as a low pressure area moves off the Florida peninsula this afternoon and emerges into the northeast Gulf Wednesday and moves west towards the north central Gulf coast Thursday. Small craft exercise caution conditions are likely with at least a medium chance for small craft advisories depending on how the low pressure evolves and where it tracks. There is a medium chance, a 40% chance, of tropical development as it moves over the northeastern Gulf.

Fire Weather
Issued at 145am EDT Tuesday July 15 2025

A seasonably moist and unstable air mass will be in place for the next several days with daily chances of showers and thunderstorms. Fire weather concerns are expected to be minimal outside of gusty and erratic winds near thunderstorms along with lightning and pockets of heavy rain.

Hydrology
Issued at 145am EDT Tuesday July 15 2025

Rain chances increase markedly today through Thursday as deep tropical moisture arrives and a tropical disturbance emerges into the northeast Gulf. The disturbance is forecast to trek west towards the north central Gulf by Thursday. Even after the disturbance moves west, tropical moisture hangs around with increased rain chances into the weekend. Highest rain chances will be closer to the coast and thus the higher rainfall amounts as well, though any slower or training of storms could produce locally higher amounts. The trend in rainfall amounts have slowly increased and may change depending on any development and overall movement of the disturbance. Nevertheless, there is increasing concern for flash flooding over the next few days. WPC has outlooked much of the area, especially closer to the coast, in a marginal risk for excessive rainfall through late this week.
