Just after 4 p.m., the Contra Costa County Fire Protection District announced they were responding to yet another fire — this one spanning five acres and rapidly spreading in Martinez near Alhambra Avenue and Forrest Way.

The second alarm fire closed Alhambra Avenue in both directions, and the evacuation zone stretches from Likins Avenue toward Morello Avenue. Fire crews from the Oakland and Hayward departments are helping Contra Costa County Fire Protection District crews.

The growing fire follows two separate blazes in Lafayette wherein three buildings were destroyed, including the Lafayette Tennis Club and the roof of a home.

Earlier on Sunday morning, nine people at the farmers market in Martinez were injured and sent to the hospital when forceful winds knocked over a 30-foot-tall tree and caused it to collapse. Martinez police sergeant Steve Gaul described the weather conditions as "extremely windy," which likely prompted the blaze.
