Fire Weather Watch: Chance of dry lightning sparking new wildfires

Bay Area

SAN FRANCISCO, Calif. (KRON/ BCN) — The chance of lightning sparking new wildfires has caused the National Weather Service to issue a fire weather watch for parts of the Bay Area beginning Sunday afternoon and ending Monday morning, the agency said.

A Fire Weather Watch means critical fire weather conditions are forecast to occur.

The weather watch covers the North Bay mountains, East Bay hills, Diablo Range and Santa Cruz mountains, beginning at 5 p.m. Sunday and lasting through 11 a.m. Monday, according to the weather service.

Upper-level moisture will increase throughout the Bay Area Sunday morning through Monday morning from the south.

The upper level moisture will accompany upper level instability, increasing the chances for possible thunderstorms.

NWS says thunderstorms will be a mix of dry and wet, but because of the drought and extremely dry conditions — lightning strikes could be an issue.

However, this doesn’t appear to look like the intense storm that sparked a number of fires last August. Last year’s lightning outbreak that triggered the fires was partly due to tropical influences.

But NWS explains there are no tropical influences expected with this upcoming monsoonal.

The threat for thunderstorms will go away Monday afternoon as the moisture moves northward.
