A spring heat wave sent temperatures soaring in the San Diego area Friday, providing a toasty preview of summer as thermometer readings neared triple digits in the inland valleys and broke past that barrier in the deserts.
The hot spell, which has been building since midweek, is expected to continue in earnest Saturday before beginning to ebb on Sunday, according to the National Weather Service.
Friday afternoon, the mercury edged into the low to mid-80s along the coast and in the mountains, reached the mid-90s in locales in between those zones and climbed to 103 in the desert community of Ocotillo Wells, according to the NWS.
An NWS heat advisory for the inland valleys was slated to remain in effect through 6 p.m. Saturday.
Due to the sudden and dramatic warmup, county health officials urged the public to heed the following precautions to avoid heat-related ailments:
— wear light, loose-fitting clothing;
— stay hydrated by drinking plenty of water, while avoiding alcohol and sugary drinks;
— take cool showers;
— if possible, stay in an air-conditioned area during the hottest hours of the day;
— never leave a child, elderly person or pet unattended in a car;
— refrain from strenuous outdoor activities during the hottest part of the day;
— avoid unnecessary sun exposure and wear a wide-brim hat if you need to be in the sun;
— don’t use the oven during the day; and
— call 911 if someone begins showing signs of heat stroke — which can include dizziness, nausea, confusion and intense headache. Cool the sufferer by moving them to a shaded area, spraying them with cool water and fanning them, placing them in a cool shower if they are alert, monitoring body temperature, and continue cooling efforts while avoiding giving fluids to drink until they recover.
Temperatures will drop Sunday and Monday, though afternoon highs in the deserts will remain around 100 through at least Thursday, forecasters advised.
