(KRON) — The heat across the Bay Area has been nothing short of oppressive this week, and the high temperatures are expected to continue at least through Friday. A few areas across the Bay even broke records, according to the National Weather Service.

The Vacaville area broke a record for highest temperature in the area over history on Sept. 5. As of 4:05 p.m. on Monday, temperatures in Vacaville were topping at 114.8 degrees. This blew past the previous heat record the date held when the area hit 108 degrees in 1988.

The Livermore area, however, took it a step further and broke an all-time record. The city hit 116 degrees on Monday, smashing the previous record of 108 set in 1950. Livermore’s sweltering temps were made worse by an ongoing power outage. As of Tuesday morning, some 2,561 customers remain without power.

Power went out around 6 p.m. Monday and initially, there were some 5,000 customers without power in Livermore. The cause of the power outage is not yet known. State officials have warned of rolling blackouts due to strain on the power grid. Equipment overheating due to extreme heat is another possible cause.

Power officials have stated they hope to have power restored before 3 p.m. on Tuesday.

Elsewhere, San Francisco hit a high of 97 Monday, edging past the previous record for the date which was 93 degrees in 2004. Oakland hit 100 degrees Monday, making it 5 degrees hotter than the previous record for the date.

Those who live in Salinas may be used to seeing cooler coastal temperatures, but they were not spared on Monday. Salinas maxed out at 103 degrees Monday, beating the previous record by over 10 degrees.

Hollister came close, hitting a high of 111 degrees today. The record high for the city is 112 degrees. Napa saw the same 111 degree temperature, but was just a couple degrees short of the 113 degree record. Napa and Sonoma also tied their temperature records with both cities hitting 111 degrees on Monday.
