PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Watch means that rapid rises of water and flash
flooding are POSSIBLE. Flash flooding is a very dangerous
situation.

Those in low lying areas and near streams should monitor water
levels during heavy rain and be prepared to move to high ground
quickly if flooding is observed, or NWS warnings are issued.

Drivers should be very cautious overnight. Low areas may become
flooded, and heavy rain can cause poor drainage flooding quickly.
If you encounter a flooded road, turn around, don`t drown.
