The amount of rain that fell in major Bay Area cities since early Thursday morning has been about an inch or less, National Weather Service officials said.

Santa Rosa reported 1.06 inches of rain while San Francisco recorded .81 inches and Oakland reported .59 inches, National Weather Service forecaster Steve Anderson said.

Concord reported .60 inches and San Jose recorded .28 inches, Anderson said. A gauge in Salinas collected .56 inches and in Monterey .52 inches fell, Anderson said.

Anderson said the storm was not an El Niño event.

“Cold Gulf of Alaska winter storm. … Typical winter storm.”

The storm, which concludes today, is expected to bring isolated lightning and small pea-sized hail to the Bay Area throughout the day, Anderson said.

Another winter storm is coming into the Bay Area Sunday, which will be a carbon copy of the storm that occurred Thursday and today, Anderson said.

He said it will be similar in the amount of precipitation, wind, hail and lightning.

Anderson said weather service officials don’t know when the first El Niño storm will hit the Bay Area.
