Widespread disruption to travel has resulted as Southern California has been hit by its first tropical storm in 84 years. Over the weekend, communities saw unprecedented floods, mudslides, high winds, and power outages. The Associated Press reports that Hilary has dumped over 6 inches of rain in some mountain communities, potentially bringing more rain than the average year in inland desert areas.
Although the storm has since been downgraded, in its wake, Tropical Storm Hilary brought a barrage of flash flood warnings spanning several counties. On Sunday, 20AUG, emergency alerts warned residents in the Los Angeles area not to attempt to travel unless they were fleeing an area subject to flooding.
In an unrelated event on the same day, a magnitude-5.1 earthquake rattled parts of Southern California, as reported by the Washington Post. However, the National Weather Service has dismissed tsunami concerns.
