First Frost Advisory of the Season Issued For Bay Area

The season's first frost advisory for the San Francisco and Monterey Bay areas has been issued for Wednesday night, according to the National Weather Service.

The frost advisory went into effect at 3:45 p.m. for North Bay interior valleys in Napa and Sonoma counties and the Southern Salinas Valley in Monterey County. The advisory expires at 8 a.m. Thursday, according to weather officials.

The cold temperatures will probably occur sometime between shortly before and shortly after sunrise Thursday. That will be about 6:15 to 7 a.m.

Temperatures in the affected areas will be in the mid to upper 30s. The temperature in Santa Rosa is expected to drop to 35 degrees, while Napa residents can expect temperatures around 37 degrees, according to weather officials. Some North Bay locations could see freezing temperatures.

Other locations in the San Francisco and Monterey Bay areas are expected to dip into the 40s.

Fruits and vegetables in the advisory areas may experience a light frost, and outdoor pets may need more help than usual staying warm.

Nick Roger of Mill Valley said he's concerned about some newly planted orange trees in his yard.

"You can put mulch around them, you can wrap them, and that's about it,' he said. "I guess you could put a heat lamp out there, but I don't have one."

Inside Vasco restaurant, where temperatures were in the 60s, Arthur Hindman, who's originally from Boston, said Bay Area residents don't know what real cold is.

"People can be pretty wimpy in the 40s in the 30s," he said. "I think people won't even go out, but that's here."

At Margaret O'Leary's clothing store, the chill is a thrill.

"We love cold weather," Christie Lucido said. "We want to see seasons, we want to sell cashmere sweaters, and we want to wear boots, and we want to look cute. We are excited about this cold spell. Bring it on!"

Temperatures are expected to rise slightly on Thursday, but weather officials will be watching for more cold temperatures again.
