Tuesday is expected to be the hottest day of the week, with warmer valley areas in L.A. County expected to reach the triple digits and temperatures in inland coastal areas ranging from the 80s to lower 90s, according to the National Weather Service. The hot weather will continue on Wednesday and coincide with a risk of thunderstorms that will persist through midday Friday.
Dangerous rip currents, as well as elevated surf of up to six feet, could strike beaches in Los Angeles and Ventura counties, with the highest risk on south-facing shores, especially from Point Mugu to Malibu, the National Weather Service said in a beach hazards statement, which remains in effect through Monday evening. Swimmers can be pulled out to sea by the currents, and the Weather Service is advising beachgoers to stay near lifeguard towers or avoid the water altogether.
Some areas could see significant rainfall for this time of year - around a quarter of an inch - particularly along a path from San Diego up to the Coachella Valley, the weather service said. The chance for thunderstorms will be strongest over the Riverside and San Bernardino county mountains, where some patches of heavy rainfall could cause flash flooding. The bulk of the tropical moisture will stay south and east of Los Angeles County, though showers will be possible, according to the weather service's Oxnard office.
