Marine Weather and Tide Forecast for Daphne, AL

UPDATE
Issued at 215 PM CDT Thu Oct 8 2026

Forecasters are seeing a signal that the risk of excessive flooding rainfall will shift northward as Isaias penetrates inland into early Saturday AM. The national centers has adjusted a moderate risk of excessive rainfall northward over interior southwest Alabama from the previous forecast to account for this. The flash flood watch has also been expanded northward accordingly. The duration of the watch remains the same, through Saturday afternoon. Rains are likely to add up quickly, especially where bands of rainfall move repeatedly over the same areas and in rain bands that become detached after Isaias moves inland and begins to weaken. 4 to 8" of rain is expected over the area with the potential for localized storm totals of 10 to 15". Flash/urban flooding, especially those areas that are subject to rapid water rises in heavy rain due to poor drainage, could be considerable.
This update adds the flash flood watch headlines to public products over the interior. /10

DISCUSSION
Issued at 1218 PM CDT Thu Oct 8 2026

The near term forecast is dominated by Hurricane Isaias. Isaias is tracking northeast over the central Gulf and intensifying. A southern stream upper trof over east Texas picks up Isaias which continues to lift north northeast over the central Gulf today and tonight and begins to turn more northward Friday. There continues to be some differences between the physics based global models and the AI suites on track, but the solutions still focus on the northern Gulf coast for landfall. There remains no changes to track and intensity reasoning. Isaias is expected to approach the northern Gulf coast late Friday as a dangerous hurricane at time of landfall. No changes to tropical cyclone watches and warnings.
Increasing swell packets and dangerous large breaking waves and high surf to begin arriving along area beaches Friday AM. Rip currents to be dangerous to potentially deadly. Weather continues to deteriorate going into Friday night as Isaias makes landfall.
Could also see considerable flooding rains in repeated bands spiraling in off the Gulf with the main concern being focused over southwest AL, down to the northwest FL Panhandle where a moderate risk of excessive rains is outlooked. This will especially be true in any detached rainbands that set up. Considering the rainfall, several rivers respond by going into flood this weekend.
A few may go into moderate flood stage. Storm surge inundation of 5 to 7' possible and peaking Friday night. Coastal flooding issues likely to linger into Saturday. Rainband tornadoes also possible, especially in Isaias's eastern quadrant.

Although Isaias lifts north of the area Saturday, forecasters will be watching any detached rain bands that will likely continue an excessive rain threat. Winds will be abating though through the day.

The remnants of Isaias phase with upper trof that ejects northeast up across the TN/OH River valleys Sunday with dry air expanding eastward over the deep south. As the upper trof continues to lift out, it becomes replaced by an upper ridge that amplifies over the southern U.S. next week. This brings a return to an extended period of rain-free conditions during the medium range. high temperatures quickly rise into the mid/upper 80s, with a few locales seeing lower 90's. Low temperatures remaining around 60 well inland to upper 60's/lower 70's near the coast. /10
