Calistoga Nearly Breaks Heat Record As Bay Area Hit With Triple-Digit Temps
BREAKING: National Weather Service heat warnings and advisories remain in effect Monday for the North Bay and throughout the SF Bay Area.

NAPA COUNTY, CA -- As Calistoga residents already know, the weather indeed was very hot this past weekend -- hot enough to tie a high temperature record set almost a decade ago. With the weekend's triple-digit temperatures putting much of the San Francisco Bay Area under excessive heat warnings and advisories, the National Weather Service reported several record- and near-record breaking temperatures, including in Calistoga on Sunday, where the high of 103 degrees tied with a record set on Aug. 26, 2008.
At 106 degrees, Healdsburg was the hottest spot Sunday in the North Bay, the NWS said. Elsewhere in the Bay Area, the East Bay's hottest spot Sunday was Livermore (107 degrees); on the Peninsula, it was Redwood City (90 degrees); and in the South Bay, it was Gilroy (102 degrees).
Here are the Bay Area heat records set or tied over the weekend, according to the NWS:
