I’ve looked over some late data as well as the 10pm National Hurricane Center discussions and no change is necessary to my discussion about Lee below in terms of strength or movement.
However, the bullseye of heaviest rainfall has been moved slightly farther east by one of the new computer models. The bright yellow area is a forecast of 20 to 24″ of rain.
Regardless of the exact position of the heaviest rain, people along the I-10 corridor from New Orleans to the Florida border should be prepared for excessive rainfall and major flooding. This may include washing out major highways and rail traffic.
With regard to Katia, enjoy the weekend. I still believe it is unlikely she will strike the U.S., but even if she does, there will be sufficient time to take precautions after the holiday weekend is over.
