Flood Safety Tips

Floods are the most common and widespread of all weather-related natural disasters. Flooding is an overflowing of water onto land that is normally dry. Floods can happen during: 

  • heavy rains, 
  • when ocean waves come on shore, 
  • when snow melts quickly, or 
  • when dams or levees break.

Areas located in the Nooksack River floodplain are subject to regular flooding in Whatcom County. Visit Whatcom County River and Flood for more information.

The National Weather Service issues multiple flood notices ahead of possible flooding.
