Southern California could be in for some weather whiplash this weekend.
Hot, dry, and windy conditions could make way for thunderstorms in the region's mountains all next next week, according to meteorologist Alex Biston.
The Los Angeles County Department of Public Health issued a warning Saturday morning advising people to avoid swimming, surfing or playing in the ocean waters at Avalon Beach on Catalina Island, Santa Monica Pier in Santa Monica and Mother's Beach in Marina Del Rey due to bacterial levels that exceed health standards.
A red flag warning went into effect at 1 p.m. Friday through 6 a.m. Saturday across Los Angeles County mountains from the I-5 Corridor to Lake Hughes, signaling a risk of critical fire weather conditions. Further east, an excessive heat warning is in place across the Coachella Valley through Friday night, with temperatures ranging from 114 to 118 degrees in the low deserts.
And while bone dry Southern California could use some rain, the system forecast to arrive this weekend includes monsoonal moisture and thunderstorms. A chance of thunderstorms begin Sunday, but increase into Monday and continue throughout much of the week.
