If the tracks remain close to where they have been, I'm figuring that it will cause some flash flooding, downed trees and downed powerlines. Pretty typical for spring weather here with straight line winds and thunderstorms. Only this would be more widespread.
Maybe it would be wise to prepare for the worst and hope for the best. Perhaps a few days supplies of water and batteries.
I'm preparing for power outages. I think by the time it gets here that's going to be the biggest problem.
