My dad said down where he works (Smyrna - just outside the perimeter North), that firefighters wearing chest waders were rowing jon boats to get people out of flooded apartments.
Pulling out of the school today, I saw cars sitting in the gully waiting to pull out submerged up to the center cap on the wheels. In the next day or so, my dads shop will likely get a few (possibly many, at this rate) cars in for new engines, as they hydrolock them, when running through puddles with the low air intake they put on these new cars.
