San Diego to see blazing heat over weekend

  SAN DIEGO (KUSI) — The first major heatwave this season will hit San Diego County Friday, rocketing temperatures by 20° and pushing numbers into triple digits in some areas.

A NWS excessive heat warning for the deserts will take effect at 10 a.m. and extend until 8 p.m. Sunday. A less severe heat advisory for the valleys
and for mountain locales lower than 6,000 feet will also be in effect.

“The effects of the excessive heat will be magnified since high temperatures toward the end of May were below average. High temperatures will be around 15 to 20 degrees above average today and Saturday,” the National Weather Service said.

Inland and valley areas will be hit the hardest. A thick marine layer will keep temperatures cool along the coast over the weekend. Due to the thick marine layer, the NWS issued a dense fog advisory until 9 a.m. Friday. Morning and evening fog in coastal areas will break apart mid-day to sun.

The NWS urged residents to protect themselves and their loved ones against dehydration, heat stroke and other heat-related illnesses. They were advised to stay well-hydrated, avoid working in the sun, check on neighbors and relatives — especially the elderly — and provide plenty of water to pets and

Residents were also urged to never leave a child, an elderly person, or a pet in a vehicle parked in the heat as interior temperatures can quickly reach lethal levels.

Temperatures will begin to cool Sunday as high pressure begins to break apart.

After dense morning fog clear, Friday’s high temperatures are expected to be: 73 to 78 degrees at the beaches, 83 to 88 degrees inland, 86 to 91 degrees in the western valleys, 93 to 98 degrees near the foothills, 93 to 100 degrees in the mountains and 109 to 114 degrees in the deserts.
