Air quality in parts of the North Bay reached grim levels Wednesday as a red flag warning persists due to fire weather.
Smoke was evident in parts of the North Bay from wind gusts, which reached up to 50 mph at higher elevations overnight, said Rick Canepa, a meteorologist with the weather service’s Monterey office.
The North Bay and Sacramento Valley are directly in the path of air flow from fires in Oregon and Northern California, including the 4,616-acre Deep Fire in Trinity County.
“Since the weather systems are coming in from that direction, we’ll have to expect at least some smoke to continue following today,” he said.
The air quality index is at a moderate level in most of the North Bay, according to AirNow. At this stage, when the air quality fluctuates between 51 and 100, the air is acceptable but there may be some risk for people sensitive to pollutants. This is the level just above “good” on the index.
Parts of northern Sonoma County, most of Mendocino and Lake counties, and the edge of Napa County face air deemed “unsanitary” and “unsanitary for sensitive groups.” At regarding noon, Cloverdale has an air quality index of 155, regarding 105 above healthy levels.
At these levels, many residents might experience health effects.
However, the worst of red flag day is over, Canepa said.
The red flag warning issued by the weather service Tuesday for southern Shasta County through the inland North Bay Mountains and Sacramento County will expire at regarding 8 p.m. Wednesday.
The advisory was prompted by low relative humidity and expected low humidity levels to rise overnight along with winds of approximately 15 to 20 mph.
Temperatures are also expected to hit a high of 90 degrees in the inland North Bay valleys on Wednesday, with Santa Rosa reaching 95 degrees.
Canepa said difficult residents likely won’t feel much of a change in relative humidity, which is expected to stay around 30%, and northerly offshore winds are expected to ease slowly throughout Wednesday.
