DITCHES OVERFLOW.
- FLOOD WATERS CAN ENTER SOME STRUCTURES OR WEAKEN FOUNDATIONS.
SEVERAL PLACES MAY EXPERIENCE EXPANDED AREAS OF RAPID
INUNDATION AT UNDERPASSES, LOW-LYING SPOTS, AND POOR DRAINAGE
AREAS. SOME STREETS AND PARKING LOTS TAKE ON MOVING WATER AS
STORM DRAINS AND RETENTION PONDS OVERFLOW. DRIVING CONDITIONS
