LOS ANGELES (CNS) – An extended heat wave is expected to blanket Southern California Friday as an early season hot spell, which broke multiple record-setting highs, continued over the region.
The National Weather Service issued a heat advisory that will be in effect for the bulk of the Southland through 8 p.m. Friday, with temperatures of 90 to 100 degrees anticipated.
By midday Thursday, many areas had already seen temperatures reach the mid-80s or even mid-90s, and forecasters said highs could be 15 to 25 degrees above normal.
The heat wave was forecasted to affect the region through Sunday with a minor cooling on Saturday, but next week will include significant additional warming because of a very strong ridge of high pressure building over Southern California.
“There is a high risk for heat illness for sensitive populations including the very young, the very old, those without air conditioning, and those active outdoors,” according to the NWS.
Forecasters urged people to drink lots of fluids, avoid the sun when possible and check on relatives and neighbors.
“Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.”
Friday is expected to be the hottest day of the week.
“On Saturday, all areas will experience a cooling trend with coastal/valley areas cooling as much as 5-10 degrees,” according to the NWS. “However on Sunday, as the upper level high begins to strengthen again and weak offshore surface gradients develop, temperatures will increase yet again, generally into the 80s to lower 90s.”
Elevated temperatures are expected to continue next week, with forecasters saying more heat advisories could be issued as early as Monday and continuing through Thursday, and some excessive heat warnings possible Tuesday through Thursday.
“Given the unprecedented length and magnitude of this extreme heat wave, heat stress will be a real threat each day, especially in areas that aren’t used to the heat, like the coastal areas, where people may not have methods to cool off their homes,” forecasters said. “Try to complete outdoor activities early in the day or in the evening, and don’t leave people or pets in cars.”
Cal/OSHA urged employers Wednesday to take precautions to protect workers as temperatures rise across the state.
“This is one of the first heat waves of the year, with temperatures rising above the seasonal average,” the agency said in a statement. “Employees may not yet be acclimatized to high heat and may need additional breaks and interventions when they adapt to the conditions. Cal/OSHA reminds employers to be vigilant, especially with newer employees, and ensure that employees have shade, water and rest breaks to prevent heat illness.”
