MENDOCINO Co., 3/14/23 – An atmospheric river continues to hover over Mendocino County, bringing heavy rain, high winds and flooding. Reports of mud and rock slides and downed trees and power lines have dotted the transportation landscape since this morning, Tuesday, Mar. 14. Avoid unnecessary travel if you can as road conditions continue to be treacherous countywide.
A flood watch is in effect across the county until 5 a.m. Wednesday, Mar. 15. National Weather Service Eureka (NWS Eureka) anticipates that “excessive runoff may result in flooding of rivers, creek, streams, and other low-lying and flood-prone locations.” This includes urban areas, locations with poor drainage, and low-water crossings.
NWS Eureka predicts the Russian River near Hopland will reach minor flooding stage at 15.1 feet later today, Tuesday, Mar. 14. The Navarro River is currently flooding State Route 128, resulting in closures from State Route 1 to just west of Navarro. Caltrans reports that the Garcia River continues to rise along State Route 1 near Point Arena. Comptche Volunteer Fire Department reports that parts of State Route 1 may close due to the river flooding this afternoon. We will keep you updated if it closes.
Additionally, a wind advisory is in place until 5 p.m. today, Tuesday, Mar. 14. The county may see southerly winds between 15 and 25 mph with gusts up to 50 mph. High winds can blow around unsecured objects, bring down trees, and cause power outages.
Over 1,000 PG&E customers are without power across the county. The largest outages are in the Albion area (915 customers). PG&E cites an “equipment issue” as the cause of the outage. No estimated time of restoration is available. To the south, over 900 customers in Sea Ranch are without power, also caused by equipment and with no estimated time of restoration. You can check for individual outage information on the PG&E outage map here.
Thankfully, tomorrow will bring a break from the wet weather, with mostly clear conditions and highs in mid-50 to low 60 degrees.
