5 inches of rain here is not uncommon... we can handle that (the record is 10 inches in one day in 1995) Heres something from the news last month "Sanibel Island measured 4.28 inches and a weather station to the east, in mainland Fort Myers reported 3.14 inches"
Im not saying it doesnt cause some problems (ive seen fish swimming down the middle of my street) but 5 inches isnt too much to handle
