December 13 to December 19 – A high pressure system still exists off the California coast. Weather will remain sunny, dry and warm during the day with chilly to cold nights dipping into the mid to low 30s. The cold surface temps under a warmer air mass aloft creates an inversion and has started the season’s escalated wood smoke concentrations in the susceptible areas of the San Lorenzo Valley. Elevated north winds, just off coast, Friday night through Sunday evening should blow the wildfire smoke out of our area and off bay. The AQI for most monitors within the district are predicted to remain in the GOOD category for PM2.5, while most areas of the San Lorenzo Valley may reach Moderate to USG.

UNTIL FURTHER NOTICE, ALL BURNING IS BANNED WITHIN STATE RESPONSIBILITY AREAS (CAL FIRE JURISDICTION) IN MONTEREY AND SAN BENITO COUNTIES. BURNING IS NOT AUTHORIZED UNTIL CAL FIRE LIFTS THE BAN. PLEASE CONTACT YOUR LOCAL FIRE DISTRICT FOR MORE INFORMATION.
