The first Red Flag Warning of the year has been issued by the National Weather Service for the interior North Bay mountains, in effect from 11 p.m. Tuesday evening to 8 p.m. Wednesday. Conditions for rapid fire spread will be most prominent along the higher terrain in eastern Napa county. Do not burn outdoors.
Spare the Air
The Bay Area Air Quality Management District has issued a Spare the Air alert for Wednesday, Aug. 30 because of a forecast of unhealthy smog levels in the region. Air quality is expected to reach “moderate” or “yellow” levels, according to a AirNow.gov forecast published Tuesday.
High inland temperatures and light winds are expected to combine with motor vehicle exhaust to create unhealthy levels of smog, otherwise known as ozone, according to the air district. Smoke from fires near the California-Oregon border may also contribute to the bad air quality.
The Spare the Air alert is the sixth issued for smog this year, air district officials said, noting that smog can cause medical issues like throat irritation, congestion, and chest pain and is particularly harmful to young children, older adults, and people with respiratory and heart conditions.
People can find out when an alert is in effect by registering for emails at www.sparetheair.org, calling (800) HELP-AIR, downloading the Spare the Air app or connecting with Spare the Air on social media.
Cooldown to follow warm Wednesday
The National Weather Service expects Wednesday to be the hottest day of the week before cooler temperatures prevail for Labor Day Weekend.
