IRE WEATHER,Hydrology
.KEY MESSAGES... Updated at 317pm EDT Tuesday Oct 6 2026

- A tropical disturbance in the Southwest Gulf has a High (90%) chance of developing into a tropical depression as it moves northeastward towards the Central Gulf Coast. Regardless of the track, there is an increasing potential of heavy rainfall and flooding late this week and weekend. Be sure to check back often for the latest forecast throughout the week.

- A Small Craft Advisory is now in effect for the coastal waters from through at least Thursday morning. Northeast winds of 20 to 25 knots and seas building greater than 3 feet will be hazardous to boaters.

.SHORT TERM... (This Evening through Thursday) Issued at 317pm EDT Tuesday Oct 6 2026

Current surface analysis shows a stalled frontal boundary draped across the northeastern Gulf over into Central FL with northeasterly flow across our area. Southwesterly flow just off the surface is helping the deep tropical moisture stream up over the shallow stable surface layer, providing a blanket of cloud cover along with passing light rain showers. Heavier rain and storms may develop closer to the stalled front over the waters but should remain mostly offshore. This pattern will largely continue for the next couple of days with the cloudy conditions keeping highs in the low 80s and low temperatures in the 60s.

Long Term
(Thursday night through next Monday) Issued at 317pm EDT Tuesday Oct 6 2026

All of the focus for the extended term turns towards the potential for tropical development in the Gulf. An area of low pressure currently in the Bay of Campeche continues to look increasingly favorable for development into a tropical depression or tropical storm within the next day or so. This system is forecast to drift over towards the Yucatan before turning north/northeastward and increasing in forward speed before eventually moving across the Central Gulf Coast sometime Friday or Saturday. Regardless of development, this system is likely to bring heavy rainfall to the region Friday into the weekend, with the greatest threats generally west of the Apalachicola and Flint rivers. With this tropical system, generally 3 to 6 inches of rainfall is forecast with isolated amounts near 10 inches possible. If realized, these totals are likely to lead to at least isolated flash flooding and river flooding especially given the soggy antecedent conditions. It is too early to determine what wind, surge, or tornado impacts this system may have (if any) to our local area.

Marine
Issued at 317pm EDT Tuesday Oct 6 2026

Fresh to strong northeasterly breezes continue over the northeastern Gulf through at least mid-week. Seas will build to greater than 3 feet today and remain elevated through the rest of the week. A stalled front over the northeastern Gulf will cause scattered to numerous showers and a few thunderstorms to persist through the week, especially just offshore. Eyes turn to a developing tropical system currently in the Bay of Campeche for potential impacts late week into the weekend.

Fire Weather
Issued at 317pm EDT Tuesday Oct 6 2026

A cold front stalling across the southeastern Florida Big Bend and northeastern Gulf today will keep the highest chances for rain mainly in Florida today and Wednesday. Brisk northeasterly winds develop today across much of the area with a drier air mass nudging into the region on Wednesday and Thursday. Relative humidity values will generally drop to 40 to 55 percent Thursday outside of the southeastern Florida Big Bend where minRH will generally remain greater than 70%. A much wetter pattern is expected to return Friday into the weekend. There are currently no fire weather concerns.

Hydrology
Issued at 317pm EDT Tuesday Oct 6 2026

Widespread rainfall totals of 4 to 7 inches with isolated totals of 10 to 12 inches have fallen over the last 5 days. Area rivers are on the rise, but very dry antecedent conditions before this recent event has allowed us to avoid river flooding so far. However, a tropical system is expected to move across the Central Gulf Coast late this week into the weekend, bringing 4 to 6 inches of rainfall to the area with isolated amounts near 10 inches possible. Areas generally west of the Apalachicola and Flint Rivers have a slightly higher heavy rainfall risk than areas east. Given the now soggy conditions, these additional rainfall totals would likely cause at least isolated flash flooding and some instances of river flooding.
