Two people have been found dead in Sonoma County in less than 24 hours from the effects of the atmospheric river storm systems battering the Bay Area this week, authorities said Thursday.

Days of relentless rain have flooded roads and downed trees across Sonoma County, forcing multiple closures. As of 9:30 a.m. Friday, at least 20 roads were closed due to storm damage, according to Sonoma County’s road closure map, including:

A flood advisory was issued by the NWS San Francisco CA on Thursday at 2:59 p.m. in effect until Friday at midnight for Sonoma County.

Two storm-related deaths were reported around Santa Rosa in the last 24 hours as rivers swelled and another round of rain moved in, authorities said Thursday morning.

Evacuation orders were still in effect on Wednesday afternoon for the low-lying areas of the Russian River for 34 miles all the way from Healdsburg to Jenner on the Pacific. People under the 36-foot level were ordered to evacuate but many folks did not according to one knowledgeable source.

Flooding coupled with saturated soils and landslides triggered by Tuesday’s drenching rain, has caused multiple road closures across the region.
