Marine Weather and Tide Forecast for Dauphin Island, AL

DISCUSSION
Issued at 115 AM CDT Fri Oct 16 2026

Monitoring the potential for fog development tonight across the area as low level moisture gradually increases and winds become light. This will favor fog, some potentially dense in some areas especially across coastal Alabama into the western Florida Panhandle where moisture will be greatest. At this time, it appears that limited coverage will preclude the need for a dense fog advisory.

A potent upper level trough will dive southeast across the Middle Mississippi and Tennessee Valleys tonight and Friday then off of the Southeast U.S. coast by Friday night. This will drive a strong cold front across the region later this afternoon and tonight.
Moisture advection in advance of this front should remain limited, but may be enough along with lift along the front to produce a few showers today along the coast. Most areas should remain dry with the frontal passage.

Another potentially high impact weather situation is likely to develop behind a strong cold front that will move through the forecast area Friday afternoon and evening. Behind the front, strong cold air advection and mixing will support the development of strong northerly wind gusts later Friday night through Saturday. This raises concerns especially across areas that experienced significant damage across portions of the western Florida Panhandle into interior portions of southwest Alabama.
Latest short-term high resolution model guidance is suggesting the potential for several hours of wind gusts approaching 40 mph late Friday night into Saturday morning. The strength of these winds will have the potential to down numerous additional trees that were damaged by the extreme wind event associated with the sting jet on the west side of Hurricane Isaias. This would likely result in additional power outages in the hardest hit areas. We plan to issue a wind advisory this evening and add special wording to account for this threat.

Temperatures will drop significantly behind the front with high temperatures over the weekend only recovering into the upper 60s to lower 70s, with lows in the middle to upper 40s over interior areas to the lower 50s near the coast.

Upper level ridging will rebuild into the forecast area early next week with dry weather and slowly moderating temperatures anticipated through next week. /JLH

FIRE WEATHER
Issued at 115 AM CDT Fri Oct 16 2026

...A FIRE WEATHER WATCH IS IN EFFECT FOR INLAND SOUTH MISSISSIPPI FOR SATURDAY DUE TO GUSTY WINDS AND DRY FUELS...

Areas of fog will continue to develop through sunrise with the potential for a few patches of dense fog near the coast. Any fog will quickly dissipate Friday morning.

Dry conditions are expected over most of the area on Friday except for isolated showers near the coast. A dry day is expected Saturday. Afternoon relative humidity values remain above critical levels Friday, but may see daytime relative humidity values dropping into the 30-35% range in some area. Surface winds may be a problem Friday afternoon and Saturday after a strong cold front moves across the area Friday afternoon. Transport winds will be mostly westerly to northwesterly on Friday and northerly Saturday. Dispersion index values will be fair to good on Friday and Saturday. Relative humidity values on Saturday fall to between 25-30% by Saturday afternoon which will increase the wildfire danger. /JLH
