Forecasters were predicting a chance of monsoonal showers, thunderstorms and possible moderate to heavy rain Monday in the Los Angeles and Ventura county mountains and the Santa Clarita and Antelope valleys.
Isolated to scattered showers will likely continue through at least Monday, especially in the mountains and deserts, according to the National Weather Service. The chance of showers will be lower Monday and limited to the mountains and Antelope Valley, the NWS said.
Record temperatures were reported in parts of Los Angeles County on Sunday night. A record warm overnight temperature of 72 was reported in Burbank. The previous record was 71 in 2020.
A record warm overnight temperature of 69 was reported at LAX. It tied the previous record set in 2015.
A flood warning was issued until Monday night in Riverside County.
A warming trend will develop for midweek as the air mass dries out, the NWS said. A return of monsoonal moisture is possible for next weekend.
A beach hazards statement was also issue through Wednesday afternoon at the Malibu coast and other Los Angeles County beaches, where dangerous rip currents and breaking waves were expected due to elevated surf of 3 to 6 feet.
Swimmers and surfers were advised to remain out of the water due to hazardous swimming conditions, or stay near occupied lifeguard towers. Rock jetties can be deadly in such conditions as well.
Despite the chance for precipitation, weekend temperatures remained high, lingering in the 70s to upper 80s from the beaches to downtown Los Angeles, exceeding 90 degrees in many valley areas and approaching 100 degrees in the Antelope Valley.
Hot, muggy weather is expected to continue throughout the week, with valley highs well into the 90s.
