Hurricane Rosa Threatens California, Las Vegas and Arizona With Flash Floods

Moisture from Hurricane Rosa could cause flash flooding to Baja California, eastern California, Las Vegas and Arizona as it approaches the coast late Sunday.

The remnants of Rosa could bring as much as a year’s worth of rain to desert areas such as California’s Imperial Valley and Arizona’s Yuma County — both significant producers of vegetables for the nation.

“The big concern is the moisture and how much rainfall we’re going to get,” said Andrew Deemer, a meteorologist for the National Weather Service in Phoenix. The National Hurricane Center said the main hazard is heavy rainfall in Mexico and the American Southwest.

Swells generated by the hurricane were also expected to produce life-threatening surf and rip currents off Southern California.

In southeastern California and Arizona, isolated thunderstorms are possible Sunday, leading to heavier rainfall Monday into Tuesday. It’s possible that 2 to 4 inches of rain could fall in one to two days.
