CATHEDRAL CITY, Calif. (AP) — Crews worked to dig roads, buildings and care home residents out of the mud across a wide swath of Southwestern U.S. desert Monday, as the first tropical storm to hit Southern California in 84 years headed north, prompting flood watches and warnings in half a dozen states. The National Hurricane Center said only vestiges of a weakened system was moving over the Rocky Mountains. Hilary first made landfall as a hurricane in Mexico’s arid Baja California Peninsula on Sunday before becoming the first tropical storm to hit Southern California in 84 years. Officials warned it still could cause severe flooding and mudslides in areas.
