Remnants of Hurricane Rosa are expected to drop rain in the desert

RIVERSIDE, Calif. — The remnants of Hurricane Rosa are expected to drop rain in the desert and mountain regions of Riverside County as early as Sunday, according to the National Weather Service and the First Alert Weather Team.

Although the hurricane is expected to weaken as it moves up Mexico’s Baja peninsula and into the Southwest region, meteorologists say it will still dump 1 to 1.5 inches of rain in mountain areas, .25 to 0.75 inch in the Coachella Valley and .25 to .5 inch in some high desert areas, such as the Morongo Basin, through Tuesday.

Some Inland Valley cities may also be dampened by rain, according to the NWS.

Forecasters said scattered thunderstorms could develop as early as Sunday evenig in the deserts and mountains.

Hurricane Rosa was a Category 4 hurricane on Thursday but was downgraded to a Category 1 by Sunday, and is expected to weaken to tropical storm strength in the overnight hours, according to the National Hurricane Center. The track of the remnants has moved farther Eastward, reducing the expectation of rainfall in the Valley and throughout Southern California, but a Flash Flood Watch remains in effect in Eastern Riverside County.

The Emergency Management Department warned residents in the burn areas of the Cranston and Holy fires that the potential for six days of moisture could trigger mud and debris flows around locations where the vegetation was consumed by the fires.
