January 28, 2021 - The National Weather Service has issued a Flash Flood Watch for west of the mountains (below 5,500 feet). It will go into effect from 7 pm Thursday to 4 pm Friday.

This means that bands of heavy rain are expected and property owners should take every measure to prepare their properties with proper stormwater best management practices (BMPs). 

Below are some useful resources that the County of San Diego has developed to show what BMPs could help to protect your property from this rain event and future rain events.
