As Helene approaches the Big Bend region of Florida, a lot of moisture will be pulled northward, and parts of Alabama will face the threat of very heavy rainfall and flooding.
As you can see in this graphic, flood warnings are in effect not just for parts of our state, but for almost all of Georgia, and of course the warnings extend all the way down to the Florida Panhandle.
Here is the latest Day 1-5 WPC rainfall forecast graphic. In Alabama, there is a pretty clear boundary of where the heaviest rain will fall, and that boundary is based on the latest track of Helene. The highest rainfall amounts will be about east of I-65. Generally 4-6 inches, locally 8-10 inches depending on where some of the heavier bands form.
