5:00 PM Update Dec. 15: Fairfax and San Anselmo have both sounded their flood alarms, and Woodacre has similar flooding. Again, these are areas north of Sausalito but please take care near any local streams in case the rain causes the same thing here.
4:45 PM Update Dec. 15: The National Weather Service has issued a warning for flooding partially blocking the southbound off-ramp from Highway 101 in Sausalito. Please use extreme care if you are returning home to Sausalito via Highway 101 from the north, and depending on exact conditions you may wish to exit at Spencer Ave. at the top of the hill instead of at the northern offramp.
The Marin Dept. pf Public Works had tweeted a photo of flooding next to the northbound ramp to 101, at the northern end of Bridgeway, showing impacts around Pohono St., the Manzanita Park and Ride Lot and Gate 6 1/2 Road.

4:20 PM Update Dec. 15: The Flash Flood Warning for Northern Marin and Southern Napa counties has now been extended to Corte Madera Creek in central Marin. This means that Corte Madera Creek is expected to reach flood stage soon and is rising rapidly.
This does not mean that creeks in Sausalito will flood, but it makes the Flood Watch here even more serious because Corte Madera is just two “watersheds” north of us, on the other side of Mill Valley. If you are in a Sausalito location adjacent to any kind of creek or stream that rises when it rains please use extreme caution and check the tide tables. Do NOT attempt to cross flooded roads — you may not be able to see that the roadway has washed out beneath the water.
Here’s a video tweet showing how fast the creek rose in San Anselmo:

The National Weather Service has issued a flash flood watch for interior valleys in Marin — and that means Sausalito’s steep valleys in Hurricane Gulch and Old Town, above Caledonia St., in Spring Valley and in Nevada Valley.
Watches mean that flash flooding could happen in this storm, but it is not certain to occur.
