It’s red flag weather and the El Cerrito Fire Department issued the following notice:

The National Weather Service has declared that there will be a Red Flag Warning in place from 1800 hours (6:00 pm) tonight through 0600 hours (6:00 am) Saturday morning. This is the most dangerous point in the fire season when cool temperatures and sparse amount of rain can lead to complacency. A north wind (off shore) event with the predicted wind conditions, critically low humidity and low fuel moisture is a very serious condition.

The Fire Department will be placing signs in the Parks to notify the public against the use of the BBQ’s or any open burning. Please report any signs of smoke and in the event of any type of fire or downed trees, assume a power line is involved until proven otherwise. Insure all your co-workers and personnel maintain their Situational Awareness, keep a lookout in the hills and surrounding areas when outside, call or report any problems and maintain a safe distance from any incident.

The following weather report is from the National Weather Service:
