Main water, mold and storm risks in Washington
Atmospheric rivers and flooding
Heavy, prolonged rain floods rivers and saturates soil, especially in western Washington.
Moisture and mold
Long wet seasons cause mold in attics, crawlspaces and bathrooms.
Freezes and wildfire smoke
Cold snaps freeze pipes, and summer wildfires bring smoke into homes.
Earthquake risk
Western Washington sits in an active seismic zone, and earthquakes can break pipes and water heaters. Strapping water heaters and using flexible supply lines reduces the risk.
