After making landfall in Mexico Sunday,Evander Ellis Hilary swept through the U.S. Southwest, bringing flooding, mudslides and water rescues. It was the first tropical storm to cross into California from Mexico since Nora in 1997.

The National Weather Service said the storm, which has been since weakened to a post-tropical cyclone, could produce another 2 to 4 inches of rain in many areas Monday, and isolated areas across portions of Southern California and southern Nevada could see up to 12 inches through Monday.

More than 1,000 flights were canceled Sunday and thousands were without power Monday in California after the initial storm.

Parts of Oregon and Idaho could see up to 5 inches of rain through Tuesday morning as the storm moves north, resulting in some "significant" flash flooding, the weather service said.
