2017 North Bay Fires

 

A series of destructive and deadly wildfires ignited overnight October 8-9, 2017, impacting thousands upon thousands of residents throughout the North Bay in California. The four major fires in Sonoma and Napa Counties were the Tubbs Fire, the Nuns Fire, the Atlas Fire, and the Pocket Fire.

NWS Bay Area created an ArcGIS Story Map that takes a look back to the North Bay Fires. We analyze the 4 major fires that impacted Napa and Sonoma Counties: the Tubbs, Atlas, Nuns, and Pocket Fires. We also examine the weather conditions that enabled the explosive growth of the fires throughout the North Bay. In addition, we highlight how National Weather Service Forecast Offices responded to the fires in order to provide weather support to those decision makers on the front line, as well as key state and federal partners. Finally, we remember those lives lost as a result of the North Bay Fires and Northern California Fires in October 2017.
