Thunderstorms Expected In Mountains Near Murrieta

RIVERSIDE COUNTY, CA — Afternoon and evening thunderstorms will be possible in the mountains of Riverside County Monday through midweek. The monsoonal moisture behind the chance of thunderstorms in the mountains and deserts is expected to decrease Wednesday, according to the National Weather Service. Until then, storms may cause heavy rain, lighting and gusty winds.
