A brutal heatwave will overtake San Diego County and the rest of Southern California this week, sending temperatures into the triple digits in some areas over Labor Day weekend.
The National Weather Service issued overheating warning from 10 a.m. Tuesday to 8 p.m. Monday as temperatures soar to well below 100 degrees on the coast and soar past 100 degrees inland and in the desert with little relief overnight when temperatures will remain in the 70s along the coast.
“We’re going to see a few days here where temperatures are about 6 to 12 degrees above average, even in the coast and inland valleys,” said NBC 7 weather anchor Ashley Matthews.
Temperatures could be the hottest in the summer, by far, the NWS said.
Matthews said temperatures would start to rise Tuesday and continue to rise throughout Labor Day.
Excessive heat warning means extreme temperatures can increase the risk of heat-related illness, especially for people who work or participate in outdoor activities. Residents are urged to drink plenty of fluids, stay in air-conditioned rooms wherever possible and check on relatives and neighbors. Never leave children and pets unattended in a vehicle as the temperature inside can reach lethal levels in minutes, the NWS said.
Extreme heat and low humidity can also create high-fire weather conditions, the NWS said.
San Diego County will open dozens of “Cool Zones” for residents to escape the extreme heat. Find a list of locations here.
