EARLY MORNING UPDATE AND VIDEO:
As the Gulf tropical system continues to develop, well south of Alabama this morning, it will acquire the name Barry later today as a tropical storm and it’ll become a Hurricane Friday as it gets closer to the Louisiana. What will this mean for Alabama’s weather, as Barry interacts with an approaching front? This could be a bigger deal for Alabama than we first thought, depending on the track. I have updated our rain chances and I have new track information for the storm.
Future Barry will become a depression or tropical storm today and a Cat 1 Hurricane by late Friday before reaching the Louisiana coast Saturday.
Some areas will see prolific rainfall amounts, perhaps over 20″. BUT, how much rain here in Alabama. There are BIG differences between the EURO model solution and the GFS rain amounts. The truth most likely lies in between.
The official NHC Rainfall potential map is closer to the EURO solution.
With landfalling tropical systems comes the threat of tornadoes. Tornado threat Friday along the Alabama coast. And, that threat will expand to include much of west and SW Alabama on Saturday.
Very high rain chances at least through the weekend. (possibly longer) Tropical downpours.
