Beat the Heat: Triple-digit temps expected

Posted: Updated:

A high pressure system moving toward San Diego County is expected to bring high temperatures and gusty winds this week, along with a greater risk of wildfires, according to the National Weather Service.

"It'll start warming up a bit (today), but it really starts going up Tuesday," said Stefanie Sullivan of the Weather Service.

High temperatures could reach the mid-90s in inland areas like Mira Mesa Tuesday, while the inland valleys could hit triple digits, Sullivan said. The mercury should dip to comfortable levels at night, she said.

The hot weather should last the rest of the work week, according to the forecaster.

"Finally, by Saturday, the temperatures start going down a bit," Sullivan said.

She said the system bringing in the heat will also usher in northeast winds of 15 mph, with gusts to 30 mph, on Tuesday and Wednesday, increasing the fire danger.

The extended period of hot weather is expected to last through Friday, with temperatures 10 to 20 degrees above average, with record highs possible in some areas.

High temperatures at the beaches will mostly be in the 80s, but inland highs will be in the 90s to near 100 degrees. Inland valley and foothill temperatures will range from 95 to 110 degrees.

Highs in the mountains and deserts could also reach triple digits.

Tuesday and Wednesday are expected to be the hottest days, followed by marginally cooler days on Thursday and Friday.

The hot and dry conditions and weak offshore flow will elevate the fire danger. While the offshore winds are not expected to be very strong, the combination of triple-digit heat, single-digit humidities and very dry brush will elevate the fire hazard potential.

Gradual cooling is expected to begin next weekend.
