Storm Hilary brings floods to Southern California

STORY: Heavy rains and fierce winds have already begun to cause chaos on southern California roads as people fled the storm and some officials ordered evacuations.

Storm Hilary, which made landfall earlier in the day in the northern part of the Baja California peninsula, has been weakening over the last 48 hours. But it is still set to be the wettest storm ever to hit the U.S. Southwest, according to Zack Taylor, a meteorologist with the National Weather Service (NWS).

Areas such as Palm Springs, California, which typically gets around 4.6 inches of rain in an entire year, could receive 6-10 inches from this one storm. California's Death Valley area, which receives only about 2.2 inches of rain per year, could receive 3-4 inches from this event.
