20 inches in an 8 hour period in Florida.
Lots of flooding. Enough to close the Ft Lauderdale airport.
Lots of cars flooded. (Hint: Don’t drive into water that is over halfway up your tires. Never drive into moving water.) “Don’t drown. turn around”….People trapped in their cars in the water…(that’s their fault).
But 20 inches in an 8 hour period is a lot in any location. It can’t run away fast enough that there won’t be flooding, no matter where you live. Thing is, in Florida, there is no high ground to retreat to either.
