Hilary weakens to a tropical storm
Hurricane Hilary, once a Category 4 hurricane, was downgraded to a tropical storm Sunday as it approaches the West Coast.
The center of the storm system is currently located about 220 miles south-southeast of San Diego. It is moving about 25 mph to the north-northwest.
About a quarter of an inch of rain has already fallen in Palm Springs on Sunday morning, while San Bernardino has seen about .8 of an inch, according to the National Weather Service.
Tropical storm force winds will start moving into Southern California over the next few hours.
Catastrophic and life-threatening flooding is likely over portions of the Southwest through Monday, forecasts show.
