The National Weather Service issued a flood advisory for the Petaluma area on Saturday, effective until 1:30 p.m.

The advisory was issued at 8:23 a.m. and followed a night of heavy rain in the Bay Area that followed up on a coastal flood advisory from the NWS issued this morning, lasting through Monday afternoon.

About 2 inches of rain fell in the Petaluma area in the past 24 hours, according to data from precip.ai, which tracks live rainfall totals.

Rain is expected to stop at about 10 a.m. with less than a tenth of an inch forecast, before rain is expected to return on Sunday night and Monday.

Belmont police asked the public to avoid Shoreway Road on Saturday morning because of flooding caused by rain.

Shoreway Road is closed in both directions between 1301 Shoreway Road to Redwood Shores Parkway/Holly Street, police said in an advisory at about 8 a.m.

About an inch of rain fell in the area over the past 24 hours, according to the National Oceanic and Atmospheric Administration.

There was no estimate for when the road would reopen.

Police said the Recology site at 225 Shoreway Road is inaccessible during the closure.

Thousands of PG&E customers are without power across the Bay Area Saturday morning, according to the company's website.

The largest outages are being reported on the Peninsula and in the South Bay.
