Hollywood Heat Wave Triggers Unprecedented Heat Advisory

LOS ANGELES, CA — For the first time in California history, the National Weather Service issued heat advisories across the Southland this week as temperatures soar 20-25 degrees above normal.

Forecasters are expecting temperature records to fall before this heatwave ends, and Sunday's Super Bowl at SoFi Stadium is likely to be the hottest ever played.

"Five temperatures records are in jeopardy for tomorrow across our area. Highs will reach the mid-to upper-80s across coastal areas where a Heat Advisory is in effect," the National Weather Service announced Wednesday night. "Wintertime heat stress is a possibility, especially for those not acclimated to the heat. Please use caution and stay hydrated."

The National Weather Service's heat advisory will be in place until 6 p.m. Sunday for the L.A. County coast, including downtown Los Angeles, along with the San Fernando and San Gabriel valleys, and Orange County inland and coastal areas — with highs up to 90 degrees in some areas.

Winds in the valley were expected to range from 15 to 35 mph, with gusts up to 40 mph. The Santa Monica Mountains will see higher winds, gusting up to 50 mph, according to the NWS.

"A warming trend will continue across the region as high pressure aloft builds in and a persistent offshore flow continues through the weekend," according to the NWS. "Near record high temperatures are possible during the peak of the heat today (Wednesday) through Friday."

The unseasonably high temperatures could stretch into Sunday's Super Bowl at SoFi Stadium between the L.A. Rams and Cincinnati Bengals — potentially making for the warmest kickoff in Super Bowl history. Forecasters expect the temperature to eclipse the Super Bowl Record set 49 years ago in at Los Angeles Memorial Coliseum when it was 84 degrees. Kickoff is set for 3:30 p.m. The high Sunday is expected to be 88 degrees in Los Angeles.

Forecasters warned that "dangerously hot conditions with temperatures up to 90 degrees" are possible in some areas during the heat wave.

"Extreme heat will significantly increase the potential for heat related illnesses, particularly for those working or participating in outdoor activities," according to the NWS. "... Be prepared to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes."
