Storm Advisory

The National Weather Service has announced hazardous weather outlook for the North Bay. 

A late season storm system with unseasonably high moisture content will bring periods of rain, possibly heavy at times, to our area today and tomorrow. Light rain is forecast to develop in the North Bay by Thursday afternoon. Rainfall intensity through Thursday night is expected to be light to moderate.

Rainfall intensity is forecast to increase on Friday and rain rates could be heavy at times by Friday afternoon. Periods of heavy rain are then possible through Friday night and into early Saturday morning. Rainfall is expected to taper off by midday Saturday.

Rainfall totals from late Thursday through midday Saturday are forecast to range from 2 to 4 inches across the North Bay, except 4 to 6 inches in the North Bay Mountains. Local amounts of more than 6 inches are possible in the wettest locations of the North Bay Mountains and Santa Cruz Mountains.

High Tide Information:

Friday, April 6:  5:18 PM 5.71 ft 
Saturday, April 7: 3:49 AM 6.40 ft 
Saturday, April 7: 6:32 PM 5.77 ft 

Small rivers and streams could flood, especially if heavy rain rates persist across a watershed longer than anticipated. Flooding would be most likely in low lying and flood prone areas. 

Persons living near rivers and streams or other flood prone areas should be alert for the possibility of flooding during this Atmospheric River event late in the week. Flood watches may be issued once forecast confidence concerning rainfall amounts increases, especially if subsequent forecast models indicate higher rainfall totals or more intense rain rates.

Residents in areas with a history of flooding are advised to monitor creek and tide levels. Move vehicles to higher ground, especially in flood-prone areas. Move items stored in low-lying areas, such as basements or other areas that have flooded in the past.

Commuters who travel in areas with a history of flooding are advised to monitor high tides. Check www.mvtraffic.org prior to your trip to anticipate traffic conditions. Road closures are often posted by the Mill Valley Police Department on Twitter.

Please be advised to keep out of creeks and waterways during the storm.

Stock up on Sandbags
