Flash flood warnings are in place Thursday afternoon until Friday morning as “heavy” rainfall is expected to move into Southern California.
Recent burn scars in Los Angeles County, including the Lake, Bobcat, and Ranch 2 Fires, could see flash floods, according to the National Weather Service (NWS).
A flash flood watch is also in place in the Antelope Valley, Los Angeles County mountains and Santa Clarita Valley, according to forecasters.
The heaviest rainfall across the Southland is expected to occur Thursday night into Friday morning. Several feet of high elevation mountain snow is also expected, along with moderate to strong south winds, according to the weather service.
Rain rates up to or even exceeding 0.75 inches per hour are possible, NWS officials said.
Residents in or below the recently burned areas are urged to take the steps necessary to protect their property. Persons in the watch area should remain alert and follow the directions of emergency preparedness officials. Avoid hiking and camping in canyons and near creeks.
By Thursday late afternoon or evening, the storm could bring six hours of heavy rain and snow over Los Angeles County before tapering off late Friday morning into the afternoon.
“Much quieter weather expected over the weekend into early Monday,” forecasters said.
Heat Alert Issued For San Fernando, Antelope Valleys
A heat alert has been issued for parts of the San Fernando and Antelope Valleys, with public health officials urging residents to take precautions.
The Los Angeles County Health Officer has extended a heat alert as high temperatures have been forecast for the Antelope Valley and West San Fernando Valley, according to the L.A. County Department of Public Health.
In the San Fernando Valley, the alert is in effect until Wednesday, with temperatures in the 90s, cooling off as the week continues.
For the Antelope Valley, the heat alert has been issued through Saturday, as triple-digit temperatures continue in the High Desert.
Public Health reminds everyone to take precautions to avoid heat-related illness, especially older adults, young children, outdoor workers, athletes, and people with chronic medical conditions who are especially sensitive to negative health impacts from extreme heat.
“Cars get very hot. Never leave children or pets in cars and call 911 if you see a child or pet in a car alone,” department officials said.
Check on those at risk, like those who are sick, older adults, pregnant women, and children, and those who live alone, according to Public Health.
“While it is very important that everyone take special care of themselves, it is equally important that we reach out and check on others, in particular those who are especially vulnerable to the harmful effects of high temperatures, including children, the elderly, and their pets,” said Dr. Muntu Davis, the county health officer in a statement. “High temperatures are not just an inconvenience, they can be dangerous and even deadly. But we can protect ourselves, our families, and our neighbors if we take steps to remain cool and hydrated.”
County and City partners have planned ways to safely operate cooling centers during times of high heat. Residents who do not have access to air conditioning are encouraged to take advantage of these free cooling centers. To find a location visit here or call 211.
Antelope Valley Once Again Breaks Records Amid Southern California Heatwave
The Antelope Valley has once again broken records over the weekend amid a heatwave across Southern California.
On Sunday, both Palmdale and Lancaster set new records for the highest temperatures on the books for July 11, according to the National Weather Service (NWS).
Palmdale reached 113 degrees, topping the previous record of 111 degrees set over 70 years ago in 1948.
Lancaster was just slightly cooler at 111 degrees, just above the previous high of 110 set back in 1943, according to the NWS.
Excessive heat is expected to continue over interior areas through Monday, then a cooling trend will bring temperatures down to near or below normal by the end of the week, forecasters said.
The upper high continues to weaken on Tuesday and Wednesday with continued cooling, most pronounced over the interior areas of Southern California.
By Wednesday, temperatures will be fairly close to normal levels and the Antelope Valley may see highs “only” around 100, according to forecasters.
“Looking a bit into early next week, the upper high will continue strengthening, although there is some disagreement between the models,” NWS officials said. “This strengthening will likely result in another period of building heat across the desert region.”
The Antelope Valley also broke records last month when Palmdale reached 107 degrees, breaking a record of 105 degrees set in 1966.
Another Heatwave To Bear Down On SoCal Bringing Triple-Digit Temperatures
After a hot Fourth of July weekend, temperatures are expected to rise in another Southern California heatwave.
National Weather Service (NWS) meteorologists are predicting the warmest days of the week are likely to be Friday through Sunday, with the highs reaching triple digits.
The Antelope Valley will “feel the brunt of the heat” with maximum temperatures near 107 Friday and 110 degrees Saturday and Sunday, according to the NWS.
As of Tuesday, there have been no official heat advisories issued, however, the Antelope Valley is “looking like a slam dunk for heat warnings,” forecasters said.
For the Santa Clarita and San Fernando Valleys, temperatures are expected to be slightly cooler, with highs in the 90s, according to the weather service.
Cooling centers are available across Los Angeles County, for residents to take a break from the heatwave.
Public health officials are urging those impacted to take precautions to avoid heat-related illness, especially older adults, young children, outdoor workers, athletes and people with chronic medical conditions.
“High temperatures are not just an inconvenience, they can be dangerous and even deadly. But we can protect ourselves, our families, and our neighbors if we take steps to remain cool and hydrated,” said Dr. Muntu Davis, L.A. County Health Officer.
It is critically important to never leave children, elderly people, or pets unattended in homes with no air conditioning and particularly in vehicles, even if the windows are “cracked” or open, as temperatures inside can quickly rise to life-threatening levels, Davis said.
The heat combined with the extreme drought conditions elevates the already high fire danger in Southern California.
Officials with the L.A. County Fire Department are encouraging residents to have a plan for evacuations, in the event they are needed for a brush fire.
Temperatures are expected to remain in the 90s throughout next week, according to the NWS.
