San Diego County is in the grips of a record-setting heat wave on Friday as an unseasonable extended hot spell blanketed Southern California.
“Daily record highs will be broken in several locations,” said the National Weather Service. “A return of onshore flow will bring some cooling to the coastal basin over the weekend, but temps will remain above average nonetheless.”
A strengthening high-pressure atmospheric system combined with winds out of the east will bring widespread record heat until the end of the week. High temperatures will be 20 to 25 degrees above average west of the mountains through Friday, according to the National Weather Service.
On Thursday, several record-breaking hot temperatures were reported across the region:
As a result of the hot temperatures, the NWS issued a heat advisory for coastal and valley communities that will be in effect until at least 8 p.m. Friday.
Maximum thermometer readings through Friday are likely to reach the low to mid-80s near the coast and the 90s across the inland valleys, tying or breaking records, the NWS reported. The East County highlands and desert locales will get less dramatic warming, up to about five degrees, meteorologists said.
The weekend will be less toasty but still unusually warm for this time of year, according to the NWS.
Expect a mix of 60s and 70s at the coast Saturday with daytime highs trending closer to the 80s across the valleys, but the relief doesn’t last for long. We’ll start warming up again next week, and it could be even hotter from Tuesday through Thursday. It looks like a long stretch of dry and very warm weather ahead, with more record heat possible, NBC 7 meteorologist Brooke Martell said.
Tips to help keep cool and safe:
County officials offered tips on how people and their families can stay safe:
Drinking plenty of fluids
Stay out of the sun
Wear light, loose-fitting clothing
Avoid using the oven to cook
Limit strenuous activities to early morning or evening
Take refuge in air- conditioned spaces if possible
Check in on potentially at-risk friends, relatives and neighbors
Responding to Signs of Heatstroke or Heat Exhaustion:
First and foremost, if you find someone who is suffering from symptoms of heatstroke or heat exhaustion — dizziness, nausea, confusion, headache — call 9-1-1 and start cooling them. DO NOT give them fluids to drink. A person with heatstroke may not be able to swallow. Fluids could run down their trachea into their lungs and make it hard for them to breathe.
After calling 9-1-1, start cooling the person by moving them into the shade, spraying them with cool water and fanning. Place them in a cool shower if they are alert, monitor their body temperatures and continue cooling them.
