Parts of Southern California are under heat warnings as the hot and dry conditions persist during the Labor Day holidays.
The heat warnings are in effect until 8 p.m. for the mountains of Santa Clarita Valley, Ventura and Los Angeles Counties, as well as Orange County and the interior of the country.
“Today you want to avoid too much heat,” NBC4 forecast Belen De Leon said.
A heat warning for the San Fernando expired on Sunday, but Monday will still bring temperatures close to 100 degrees in some areas.
Monday highs between 98 and 106 degrees are expected in Antelope Valley.
The Los Angeles County health official issued a heat alert for the western San Fernando Valley on Sunday and Monday and a heat alert for the Santa Clarita and Antelope valleys on Monday.
The sky will be mostly clear for the long weekend with only minimal low clouds in the morning. A high pressure ridge over central California will dominate the region, reducing relative humidity and creating bone dry conditions.
The high temperatures, combined with the extremely low humidity, will create critical fire weather conditions over the valleys, mountains and deserts of Southern California through Tuesday.
Increased surf and dangerous rip currents were also expected until Monday night. Expect surfing heights of up to 3 to 5 feet on the south-facing beaches
Swimmers have been warned to stay out of the water or swim near a lifeguard and avoid rock walkways, walls and cliffs.
A gradual cooling trend is expected to begin on Tuesday, with highs dropping to 8-10 degrees by next weekend.
