Hilary, which was downgraded from a hurricane to a tropical storm on Sunday, according to Fox Weather, is expected to arrive in Southern California late Sunday afternoon after making landfall in the northern part of Mexico’s Baja California peninsula.
The tropical storm is expected to bring periods of heavy rain and strong winds to the area. Dangerous to catastrophic flash flooding is possible in mountainous and desert areas, particularly in Nevada and inland California where debris flows and mudslides are a concern. Some areas may see tornado warnings as well.
Tropical storm warnings are in effect for much of Southern California, with more than 21 million people residing in areas covered by the warnings which stretch along the coast from Los Angeles to San Diego, and inland from Mount Laguna to Palm Springs, San Bernardino and Victorville.
According to the National Weather Service’s San Diego bureau, this is the first time the National Hurricane Center has issued tropical storm warnings for Southern California.
