Monitor the news for weather related information. If there is a flash flood watch or warning in effect, stay off the roads.

Avoid areas that are already flooded and do not attempt to cross a flooded roadway.

Be cautious when driving at night or in unfamiliar areas when it is harder to recognize flood dangers.
