MOUNTAIN AREA — Smoke from the Elm Fire near Hwy 198 in Coalinga is affecting air quality in the western portion of the San Joaquin Valley and has the potential to impact Fresno, Kings and the western portions of Kern County.
Currently, smoke impacts originally concentrated in the foothill areas to the west of the air basin have moved to the Valley floor and impacts are likely until the fire is extinguished.
The Elm Fire started on Thursday, May 18, just after 1 p.m. in Fresno County, off of Highway 198 and Alcalde Road, south of Coalinga. At this time, the fire has burned over 5,550 acres and is 20 percent contained. Highway 198 is closed from Coalinga west to the Monterey County Line. Firefighters are experiencing steep and rugged terrain and long range spotting.
Under the weather conditions present this weekend, there is potential for new fires to occur. Smoke from wildfires produces particulate matter (PM2.5), which can cause serious health problems including lung disease, asthma attacks and increased risk of heart attacks and stroke.
People with existing respiratory conditions, young children and elderly people are especially susceptible to health effects from these pollutants. Air District officials urge residents to follow their doctors’ orders when exposed to wildfire emissions and stay indoors if at all possible.
Please be advised that the District’s Real-time Air Advisory Network (RAAN) monitors are designed to detect the fine particulates (called PM2.5 which are microscopic in size and not visible to the human eye) that exist in wildfire smoke. Ash particles are much larger in size and will not be detected by our monitors.
Therefore an area may be experiencing ash impacts from these wildfires while the PM monitor reflects a moderate reading. If you can see or smell smoke or ash, that is an indication that you should be treating air quality conditions as “Unhealthy” (RAAN Level 4 or higher) and remain indoors.
Residents can check the District’s wildfire page at www.valleyair.org/wildfires for information about any current wildfires and whether they are impacting the Valley. Residents can also check the nearest air monitor to their location to determine localized air-quality conditions.
