# PRECAUTIONARY/PREPAREDNESS ACTIONS
--------------------
A Coastal Flood Advisory means that minor tidal flooding is expected. Minor tidal flooding often results in some road closures. Usually, the most vulnerable roadways will flood.
Do not leave your vehicle at a location that is prone to tidal flooding. Do not drive your vehicle through flood waters. The water may be deeper than you think it is. You will be putting yourself in danger and your vehicle may be damaged, leading to costly repairs.
