A “long and dangerous” heatwave is expected to hit Southern California this week, according to the National Weather Service.

NWS meteorologists predict an 80% chance of daytime temperatures between 85 and 105 degrees across non-coastal areas starting Wednesday. Some areas could see temperatures closer to 110 degrees.

“Now is the time to start planning ahead of the heat such as changing outdoor plans or finding places to stay cool and socialize with friends and family,” the NWS forecast reads.

The heat is expected to persist Thursday and could continue into the weekend. The heat will also bring an increased risk of wildfires in inland areas.

Along the coast, a high surf advisory remains in effect until Tuesday afternoon as Tropical Storm Elida churns off the coast of Baja California. The storm is expected to send 8-foot waves to the Southern California coast and potentially cause dangerous rip currents.

Increased humidity levels are predicted to create especially warm overnight temperatures in the 70s in the interior foothills and valleys.
