West Coast Rainy Season

The West Coast Rainy Season usually lasts from November to April, bringing heavy flooding and increased flood risks with it; however, flooding can happen at any time.

A string of large wildfires have dramatically changed the landscape and ground conditions, causing fire-scorched land to become mudflows under heavy rain. Experts say that it might take years for vegetation to return, which will help stabilize these areas.

The West Coast also has thousands of miles of levees, which are meant to help protect homes and their land in case of a flood. However, levees can erode, weaken or overtop when waters rise—often causing catastrophic results.
