The National Weather Service issued a flash flood warning for the North Bay that will be in effect until 2 p.m.
The flash flood warning includes portions of West Marin, as far north as Mendocino County and as far west as Napa Valley.
The National Weather Service advises the public to monitor later forecasts and be prepared to take action should more flash flood warnings be issued.
Creek levels in Ross Valley quicky rose late Sunday morning.
The San Anselmo Creek rose from 5 feet around 7:30 a.m. to almost 11 feet at 1 p.m. The creek’s “critical level” is 13 feet, which is the base of the building at 730 San Anselmo Avenue.
Fairfax Creek rose from 2 feet at 6:30 a.m. to spiking just a little bit above 7 feet around noon, but went down to approximately 6 feet a few hours later when the rain subsided. The creek’s critical level is 9 feet.
San Anselmo officials sounded the towns flood siren during a Dec. 3 close call when the creek levels quickly rose from 6 feet at 7:33 a.m. to just under 13 feet around 9 a.m. Fairfax Creek also saw a similarly huge spike and the Fairfax Town Hall almost flooded.
“It was so incredibly fast,” Stutsman had told Patch earlier this month.
The San Anselmo Creek water rose so quickly earlier this month it threw the town’s normal flood protocol out the window and sent officials scrambling, she said.
