Hurricane Rosa off Mexico could bring rip currents, flooding in US

Hurricane Rosa is spinning toward the Baja Peninsula Sunday as a Category 1 storm with sustained winds of 85 mph, the National Hurricane Center said.

Rosa is expected to make landfall Monday as a tropical storm then continue moving northeast, soaking the southwestern US.

High surf up to 10 feet and rip currents will begin along southern California coast today. The potentially dangerous conditions are expected to last through Monday. Some 12- to 15-foot waves are possible on south-facing shores.

More than 10 million people are under flash flood watches at the US-Mexico border along California and Arizona, and north through Utah.

Rain is expected to begin Sunday afternoon in southeastern California and Arizona, where 2-4 inches is likely to fall. Some areas could get up to six inches.

All that rain can lead to life-threatening flash flooding in the deserts, forecasters said.
