Short summary
The 9 January 2018 post-fire debris flows in Montecito and Carpinteria, California, killed 23 people and destroyed over 100 homes. We examine the meteorological conditions of the event and find that a narrow band of high-intensity rainfall along a cold front triggered the debris flow. Observed rainfall rates were extreme, but not unprecedented for the region. This work increases awareness of these rainbands as a post-fire hazard in California and other midlatitude regions impacted by wildfire.
