Mayor Wharton just tweeted this map (PDF) showing expected flooding by zip code. Slide 13 is Downtown, and it looks like some of the streets on Mud Island facing the Wolf and Mississippi Rivers will flood today.
It also shows that the on and off ramps at I-40 and Riverside are expected to flood. Not sure how that’s possible, since the ramps aren’t level. In any case, though, if you have to travel to or from Arkansas today, you may want to take the 55 instead.
Near the intersection of Second and Mud Island Drive, I notice there’s a street called Minnie. Wonder if that was named for Memphis Minnie who wrote “When the Levee Breaks?” Minnie Street, by the way, will be flooded today too.
