Red Flag Warning Extended - Wed. 10/21 at 10 PM PST through Fri. 10/23 at 8 AM PST

The National Weather Service has issued a second Red Flag Warning is in effect for the North Bay Mountains, East Bay Hills and Interior Valleys, Santa Cruz Mountains and the San Mateo Coast from 10PM PDT Wednesday 10/21 through 08AM PDT Friday 10/23. The Red Flag Warning will not begin for the Santa Cruz Mountains and the San Mateo Coast until 1AM PDT Thursday.

The concerns of the weather system are that wildfires that develop will likely spread rapidly. Erratic gusty outflow winds may result in dangerous and unpredictable fire behavior. Residents are advised to exercise extreme caution during the Red Flag Warning because a simple spark could cause a major wildfire, including the use of equipment and machinery as well as smoking.
