BIRMINGHAM, Ala. (WBRC) - FIRST ALERT FOR DENSE FOG: Be careful overnight and plan for some extra drive time. The visibility is dropping quickly as fog increases in coverage across the area. We’re also tracking lingering light mist, drizzle, and light showers, which will keep roadways wet through the early morning. Also, you’ll need the long sleeves Sunday morning because it’s going to feel much cooler, with lows in the 50s in many areas. The fog will give way to a mostly cloudy day on Sunday and temperatures will only top out in the low to mid 70s. A few scattered showers will be possible, especially east of I-65. However, rain chances will be more limited at 20%.
FIRST ALERT FOR A TROPICAL THREAT IN THE GULF REGION: We’re looking at a complex weather setup for next week as another tropical system threatens the state. A new tropical depression has formed in the Caribbean, and this will soon become Tropical Storm Zeta. This system is expected to track towards the northern Gulf of Mexico as an upper level trough approaches from the west by mid-week.
Monday will be a mostly dry day and if the clouds break, we could see temperatures as high as 81º. We’re expecting unseasonably warm and humid days, with a mix of clouds and sunshine. There will be a low chance for a few pop-up showers or a pop-up storm to start the workweek.
Zeta could become a category one hurricane as it crosses the central Gulf of Mexico on Tuesday, but wind shear from the approaching trough could weaken the system to a strong tropical storm at landfall. Landfall could be anywhere from Louisiana to northwest Florida by late Wednesday. There will be a big impact threat along the coast, including a flood threat, tropical storm force winds, and an isolated tornado risk. This system and the trailing upper trough will bring another period of higher rain chances for Wednesday and Thursday.
The wet weather is expected to move east by Friday, with much cooler air returning. This will bring the fall-feel back for Halloween, with highs in the 60s and lows in the 40s. There may be some lingering clouds next Saturday but forecast guidance shows a dry setup for next weekend. I’ll have more updates after the World Series tonight on WBRC Fox6
