What To Do
📋 Official NWS Guidance
Dangerous flooding from heavy rainfall can be expected, especially near poor drainage areas and other flood prone locations. It is harder to recognize flood dangers at night, as it will be difficult to determine the depth of the water. Roads may be damaged or washed away. Most flood deaths occur in vehicles. If flooding is observed, then turn around, don't drown.
