Southern California mountains and valleys under new heat advisories
Most of Southern California will remain under heat advisories through the coming days as high temperatures return to the region, despite the fact that the summer season has officially ended.
Forecasters said temperatures will increase Tuesday and again Wednesday, leading to potentially dangerous weather conditions before a cool-down begins Thursday.
"Hot days aren't just uncomfortable -- they can be dangerous," said Dr. Muntu Davis, LA County Health Officer. "However, if we make sure to stay hydrated and keep cool, we can protect ourselves and our loved ones, friends, and neighbors."
Record high temperatures were reported Monday in Lancaster, Palmdale, and Sandberg. It was 100 in Lancaster, tying the record for the day set in 2001. It was 100 at Palmdale Airport, breaking the record for the day of 99 set in 1980. It was 91 in Sandberg, tying the record for the day set in 1980.
The Department of Public Health issued the advisory for residents in the following areas:
- Calabasas/Agoura Hills
- East San Gabriel Mountains
- East and west Santa Monica Mountains
- Eastern Antelope Valley
- San Gabriel Valley
- Santa Susana Mountains
The advisory will last at least two days, Oct. 1 and Oct. 2.
Additionally, the National Weather Service issued an excessive heat warning for the Santa Clarita and San Fernando Valleys for the same days where temperatures could reach 108 degrees.
The heat wasn't limited to just inland regions either, with uncharacteristically warm weather settling over LA County beaches to begin October.
On Tuesday, LADPH officials issued a series of beach water warnings due to high bacteria levels caused by the warmth. Those beaches include:
- Windward storm drain at Venice Beach, 100 yards up and down the coast from the storm drain
- Mothers Beach in Marina del Rey
- Walnut Creek at Paradise Cove
- Marie Canyon Storm Drain at Puerco Beach 100 yards up and down the coast from the public access steps
- Inner Cabrillo Beach in San Pedro, entire swim area
- Santa Monica Pier, 100 yards up and down the coast from the pier
- Topanga Canyon Beach in Malibu, 100 yards up and down the coast from the lagoon
- Manhattan Beach Pier, 100 yards up and down the coast from the pier
- Las Flores Creek at Las Flores State Beach, 100 yards up and down the coast from the creek
A red flag warning of critical fire danger conditions will be in effect from 9 a.m. Tuesday until 8 p.m. Thursday for the western San Gabriel Mountains and 14 Freeway corridor, thanks to the anticipated heat, gusty northeast winds, and low humidity.
Symptoms of heat-related illnesses include high body temperature, vomiting, dizziness, confusion and hot, red, dry or damp skin. Officials implore residents to call 911 if these symptoms appear. Heat stroke is a medical emergency.
"Although it's crucial that we take care of ourselves, it's equally important that we extend our hand to those in need," Davis said. "We must look out for those who are more likely to get ill due to the heat, including the elderly, unwell, pregnant women, children, and those living alone.
If you want to get out of the heat, LA County and the City of LA will operate cooling centers. You can find the closest location here.
The NWS has set up a page to see how dangerous the heat could get in your area.
