The chance of more dry lightning has prompted the National Weather Service to extend a red-flag warning for the North Bay, a spokeswoman said today.
Forecaster Diana Henderson said the warning, which had been in effect for various parts of the Bay Area on Tuesday, has been extended until 3 a.m. Thursday in the hills and valleys of Marin, Sonoma and Napa counties.

Thunderstorms with gusty and erratic winds and lightning are possible through that time, she said.
A red-flag warning means that critical fire weather conditions are either occurring now or will shortly, according to the National Weather Service.

The warning had initially also applied to parts of the East Bay and the Santa Cruz Mountains, but the weather system that prompted it has moved north, Henderson said.
Eric Hoffman, chief of Cal Fire's Sonoma-Lake-Napa Unit, said lightning has not sparked any fires in that region yet, but pointed out that crews are battling lightning-related wildfires statewide, including in Butte and Shasta counties.
