KEY MESSAGES

Updated at 654 AM CDT Fri Oct 2 2026

- Increasing concern for heavy rainfall leading to flash flooding this weekend with multiple rounds of showers and storms, especially near the coast.

- HIGH risk of life-threatening rip currents for coastal Alabama and northwest Florida beaches through at least Monday.

- Minor coastal flooding is expected during early morning high tide cycles this weekend with water levels up to 2 feet above normally dry ground.

UPDATE

Issued at 654 AM CDT Fri Oct 2 2026

The forecast for today remains on track.

Minor coastal inundation, mainly impacting coastal portions of Mobile County, is slowly subsiding at this hour on the backside of high tide. Another round of coastal flooding is expected both Saturday morning and Sunday morning in the pre-dawn hours due to a combination of spring tidal cycles and increasing onshore flow. Guidance overnight indicates that the risk for coastal flooding will likely extend across the entire coastline over the weekend.

Rip current probabilities increased for the Sunday night into Monday timeframe, so we opted to extend the HIGH RISK of rip currents through much of the day on Monday. The risk should steadily drop through the morning hours on Monday. Overnight guidance indicates that there is an increasing likelihood of a HIGH RISK again by late Tuesday night through the middle to latter part of the week. Surf heights increase as we roll into the middle to latter part of next week as well.

High-res guidance combined with HREF PMMs have started to trend slightly higher with the potential rainfall amounts, thus giving us increasing confidence that this weekend's heavy rainfall will likely lead to at least some flash flooding issues along the coast. Bumped up the rainfall totals in our messaging to 4-6 inches across much of the area with a few locations potentially receiving up to 7-10 inches of rain through Monday. 07/mb

DISCUSSION

Issued at 158 AM CDT Fri Oct 2 2026

A wave of deep tropical moisture moving into the eastern Gulf will begin to enter the area today via southeast flow around a ridge over the western Atlantic. PWATs will rise from around 2 inches to around 2.3 inches through the day, leading to an increase in shower and storm chances. The greatest coverage will focus offshore and over coastal counties during the morning, expanding inland for the afternoon hours with PoPs as high as 60-80% south of Highway 84. Localized heavy downpours are expected with this activity and a Marginal (level 1 of 4) flash flood risk has been outlined by the WPC.

The main story through the weekend continues to be the potential for multiple rounds of heavy rainfall and flash flooding. As the wave of tropical moisture begins to converge along the northern Gulf Coast ahead of a stalled front to the northwest, PWATs are forecast to surge to around 2.4-2.5 inches, placing them above the 99th percentile for early October. Low-level convergence along and east of a broad surface trough will lead to periods of widespread showers and storms over much of the area through the weekend. As some guidance is hinting, it is not out of the question for the surface trough to close off into a weak low pressure area over the northern Gulf. This would potentially result in a prolonged period of widespread heavy rain with embedded training convection over the area, particularly Saturday night into Sunday. The deeply moist environment will support highly efficient warm-rain processes and locally intense rainfall rates. The greatest concern for repeated rounds of heavy rainfall will be near the coast, through the timing and duration of individual rounds remains uncertain.

Total rainfall amounts through Monday morning remain uncertain, but the current forecast remains for generally 2-3 inches across the interior and 3-6 inches across the southern half of the area, with locally higher amounts possible. Totals of 6-9 inches cannot be ruled out near the coast where training convection occurs. The potential for flash flooding remains a concern, particularly in urban and poor drainage locations. Since our soil can generally take a lot of rain before flooding begins given lack of recent rainfall, widespread flooding is not currently expected. The WPC maintains a Slight Risk (level 2 of 4) of excessive rainfall for the southern half of the area on Saturday and the entire area on Sunday.

The cold front is currently forecast to slowly clear the area and push offshore early next week, gradually filtering in drier air and reducing rain chances through midweek. Breezy northeast flow and cooler temperatures are expected behind the front. Uncertainty grows substantially going into the latter portion of next week.

Along the coast, continued onshore flow combined with the ongoing King tide cycle through the weekend will likely lead to minor coastal flooding during the early morning high tides, with water levels reaching up to around 2 feet above normally dry ground. The greatest concern for coastal flooding is along northern and western Mobile Bay and the Mississippi Sound early this morning, and possibly expanding to include additional portions of the coast for Saturday morning. In addition, a High risk of life-threatening rip currents continues at all area beaches through Sunday, followed by a Moderate risk early next week. JGC/98

AVIATION

(12Z TAFS) Issued at 654 AM CDT Fri Oct 2 2026

VFR conditions prevail outside of convection throughout the TAF cycle. Showers and storms will continue to develop near the coastline and push inland throughout the day. PROB30 groups continue for the terminals through early evening given the possibility of brief reductions in visibility and ceilings due to passing showers. Gusty conditions are possible along the immediate coastline throughout the day with gusts up to 20 knots at times. 07/mb

MARINE

Issued at 654 AM CDT Fri Oct 2 2026

A moderate to occasionally strong southeasterly flow persists through this weekend with seas increasing to 3-5 feet. Winds turn northerly to northeasterly behind a cold front early next week. Advisory level conditions are possible Tuesday through Friday with strong easterly winds and seas increasing to 5-7 feet. 07/mb
