Flooding often occurs following heavy rainfall and can happen very quickly. Floods are most likely to occur during the months of May through September.
If floodwaters have already arrived and you are trapped in the building, go to an upper floor or roof.
Do not cross flowing streams on foot where the water is above your knees.
Do not drive through flooded streets or parking lots (turn around, don't drown).
