On Monday following storm Hilary parts of Southern California and the U.S. Southwest faced flooding, landslides and mudslides due to record-breaking downpours overnight. The California-Mexico border, up through Las Vegas and into parts of the Northwest, affecting some 17 million Americans, were under flood and high-wind advisories, watches and warnings as the storm dumped heavy rains, according to the National Weather Service. Forecasters said rain accumulation could reach 5-10 inches in some mountain and desert areas, equal to as much as deserts would see in a year. California Gov. Gavin Newsom declared a state of emergency for much of Southern California before the storm was downgraded to a tropical depression. President Biden ordered federal agencies to dispatch personnel and supplies to the region. In the midst of the storm on Sunday, a magnitude 5.1 earthquake shook Southern California north of L.A.
