Torrential rain hits fire-damaged Santa Barbara, causing deadly mudslides and flooding
On Tuesday, 21,000 people living near hillsides in Southern California had to be evacuated due to severe mudslides and flooding. These events were caused by torrential rain, with the Santa Barbara region experiencing rainfall in many areas at a rate of over an inch per hour. The most heavily impacted areas saw close to 1.5 inches per hour. This rainfall follows a record breaking fire season that left nearly two million acres of land burnt and barren, eliminating many trees and other vegetation that would usually absorb and slow the path of water. According to Robbie Monroe of the National Weather Service in Oxnard, half an inch of rain per hour is enough to trigger mudslides. With the rate of precipitation far exceeding that threshold and the increased vulnerability from the wildfires, the results have been devastating.
