The County of San Mateo urges the public to stay indoors when possible and its Parks Department advises visitors to refrain from active use due to the unhealthy air quality resulting from the fire in Butte County.

Smoke from the Camp Fire moved in to the Bay Area on Thursday and may create health effects including shortness of breath, coughing and lightheadedness. Individuals experiencing difficulty breathing or other health issues should contact their medical provider.

The Parks advisory is in effect Nov. 9 through Nov. 12 or until conditions improve. Those with reservations this weekend at a San Mateo County Park should contact the park directly. Phone numbers are available at parks.smcgov.org. If someone chooses to cancel or change a reservation, no fees will be charged. Reservations can be rescheduled by calling (650) 363-4021 between 7:30 a.m. and 5 p.m. Tuesday, Nov. 13.

As a health precaution, on Friday, Nov. 9, the County also shut off outside air to all of its facilities and limited non-essential outside work by employees.

Due to the heavy smoke, the Bay Area Air Quality Management District has issued a Spare the Air alert through Monday, Nov. 12.
