And it depends very much on where you are. 12" of rain in 24 hours in
South Florida is not a serious event. It rapidly soaks into the very
sandy soil and then into the porous limestone that lies just a few feet
below the surface. It also helps keep the Everglades water levels above
sea level which then exerts a positive outward pressure on the ocean
salt water which would very much like to intrude inland and poison the
fresh water wells that dot the coast.
