Small hail fell in parts of the Bay Area Tuesday morning and a significant weather advisory was issued for San Francisco, Contra Costa and Alameda counties.
Around 8:45 a.m., small pea-sized hail came down for about three minutes in the Daly City area, along the San Mateo County coast and moved into San Francisco, National Weather Service forecaster Bob Benjamin said.
Short bursts of heavy showers are expected throughout the region on Tuesday, with a high likelihood of thunderstorms, Benjamin said.
He said the intermittent downpours are likely to be accompanied by hail and gusty winds. NBC Bay Area viewers in Napa shared a number of hail photos.
More rain showers, thunderstorms and lightning is expected throughout the Bay Area on Tuesday, the second day of much-needed precipitation in drought-stricken California.
And like Monday, when trees were snapped by lightning in Berkeley and Sausalito, meteorologists say more trees could get zapped on Tuesday as well. Trees explode when the trunk is stressed, and can result from extreme cold, fire and lightning.
In Berkeley, neighbors near Holly Street and Buena Avenue watched a 80-foot redwood fall on Monday after being struck by lightning around 2 p.m.
"It felt like an IED had gone off,” one witness told NBC Bay Area. Parts of the tree were found scattered throughout the neighborhood, still there on Tuesday morning.
Earlier, two homes in Sausalito were damaged after a redwood tree collapsed on the 100 block of Spencer Avenue. No injuries were reported, although more than 1,000 PG&E customers in the area were without power for at least an hour.
Showers and a slight chance of thunderstorms are likely Tuesday evening as well.
The storm forced a rain out of the Oakland Athletics matchup against the Cleveland Indians. The game will be made up in a day-night doubleheader on Wednesday.
Forecasters predict cloudy skies and a slight chance of showers on Wednesday.
