| Area Forecast Discussion National Weather Service Mobile AL 151am CDT Wednesday July 22 2026 ...NewARINE... .KEY MESSAGES... Updated at 151am CDT Wednesday July 22 2026 - Tropical Storm Warning continues for all immediate coastal zones, nearshore waters, and offshore waters of Alabama and northwest Florida. Coastal Flood Advisory is in effect until Thursday morning for all coastal areas. - Dangerous and life-threatening beach conditions expected through Thursday. High risk of rip currents for all western Florida Panhandle and Alabama beaches through Thursday. High Surf Warning is in effect until Thursday morning. Issued at 151am CDT Wednesday July 22 2026 The main story through the period is Tropical Storm Bertha with maximum sustained winds of 50 mph and is located about 80 miles south of Mobile. It is currently moving west at 6 mph parallel to the Gulf Coast with the center staying in our offshore waters. Current wave heigheights are 9.2 feet south of Orange Beach (Buoy 42012). ...THROUGH THURSDAY... Heat index values are just below the Heat Advisory threshold, but still very warm peaking at 107. The eastern half of our area will have more clouds and precipitation allowing for slightly lower heat index values in the upper 90s to low 100s. Anybody outdoors should drink plenty of water and take breaks in A/C when possible. A Tropical Storm Warning is in effect for all land zones on the immediate coast and nearshore/offshore waters of Alabama and northwest Florida. Our main impacts with Bertha are gusty winds, increasing wave heights, and an increased rip current risk. Inundation is possible with the strong onshore flow combined with high tide. A Coastal Flood Advisory in effect until 10 am Thursday for all area coastal areas and bays. Minor flooding of 1-3 feet above normally dry ground is expected especially for vulnerable low lying areas and typical trouble spots like Dauphin Island and Fort Pickens. Widespread flooding issues are not expected with this tropical system with storm totals of 1-2" with localized areas receiving up to 4". The highest coverage of precipitation will be just along the immediate coast and mainly offshore. Our moisture content remains elevated with PWATs (Precipitable Waters) of 2.3-2.4" which introduces enhanced rain rates, but nothing more than very localized flooding is expected for the remainder of the event. ...FRIDAY THROUGH THE BEGINNING OF NEXT WEEK... After Bertha departs to the west, we are on the eastern periphery of a building upper ridge under generally northerly flow aloft through the end of the week and into the weekend. This brings rain chances to a more normal summertime pattern with daily chances for isolated to scattered showers and thunderstorms, especially along the sea breeze and resultant outflow boundaries. We switch into northwest flow aloft this weekend into the beginning of next week between the ridge to the west and the upper trough digging into the eastern US. This could bring organized convection down into our area, so this is something to watch through the weekend. Heat headlines could also be possible the beginning of next week as temperatures are projected to increase into the mid to upper 90s depending on the strength of the ridge. ..Beach Forecast Dangerous and life-threatening beach conditions are expected through mid week. The rip current risk HIGH for our Alabama and northwest Florida beaches and will last through Thursday before dropping to MODERATE Friday through Saturday. Guidance shows surf peaking through Wednesday morning before slowly beginning to taper off. A High Surf Warning is in effect for surf heigheights up to 8-12 feet through 6 am Thursday for all Alabama and northwest Florida beaches. SS/97 Marine Issued at 151am CDT Wednesday July 22 2026 Tropical Storm Bertha is located approximately 80 miles south of Mobile with maximum sustained winds of 50 mph and moving west at 6 mph.

Tropical storm force winds are impacting the Gulf waters and will decrease to moderate southerly winds by Thursday morning. After the system departs, light southwesterly to westerly winds begin Thursday night and continue through the weekend.
