Join FOX40 Chief Meteorologist Kristina Werner and Dennis Shanahan for team weather coverage Sunday. Adam Epstein will have your Monday morning update.  

SACRAMENTO, Calif. (KTXL) — This weekend may see up to an average of six inches of rain across the county — with Grass Valley potentially seeing as much as 15 inches.

This increase in forecasted rainfall from the National Weather Service means the county may receive as much as a third of the county’s normal annual rainfall inside a 24 hour period.

The strongest storm will move in late Saturday, lasting into Tuesday. Much of the valley may see four to 10 inches of rain. For reference, Sacramento has only recorded 4.89 inches of rain in all of 2021.

The NWS has also issued a Flash Flood Watch for 13 burn scar areas vulnerable to mudslides and debris flow, starting Sunday morning.

A Winter Storm Watch has been upgraded to a Winter Storm Warning for Sunday evening and Monday.

The warning will begin 11 p.m. Sunday through 11 p.m. Monday for areas above 6,000 feet, the NWS said.

Cold air from the north will mix in with the atmospheric river Sunday night, causing Sierra snow levels to drop from above pass levels to near 6,000 feet.

With some areas expecting up to 10 inches of rain this weekend, PG&E said on Saturday it has more than 500 crews on standby to respond to potential outages.
