SJVAPCD issues health caution alert through the weekend due to smoky skies in the San Joaquin Valley

As most of you are painfully aware, the skies in many parts of California are filled with smoke from the numerous wildfires throughout the state.

Smoke from those fires has severely impacted ambient air quality. As a result, the San Joaquin Valley Air Pollution Control District has re-issued a health caution due to the unhealthy levels of large particulate matter (PM) and PM2.5 (particles less than 2.5 microns in diameter).

The health caution will remain in effect until the fires are extinguished.

The District anticipates the air quality to be unhealthy throughout the weekend and has warned residents to stay indoors with all windows closed as a result. They also caution that the common cloth and paper masks worn by many to help reduce the transmission of the novel coronavirus may not be adequate protection from wildfire smoke.

Please exercise caution. Stay safe. Stay indoors.

Smoke in the San Joaquin Valley still a problem

This will be just a short post. Here is a screenshot of RAAN data from the SJVAPCD for Bakersfield today.

Notice the more than tripling of PM2.5 data in the span of just a couple of hours around 11 AM to 1 PM today. It now exceeds Level 5.

Please stay inside if you can. Be sure to mask up if you are outside.

Smoke in the San Joaquin Valley - one more reason to stay indoors

If you live just about anywhere in California's San Joaquin Valley, you may have noticed that the sky is gray, the mountains are nowhere to be seen, and the acrid smell of  a burning "something" is in the air.

Wildfires throughout the state are currently impacting the Valley's air quality. As a result,  San Joaquin Valley Air Pollution Control District (SJVAPCD) air quality data is being reported as unhealthy for sensitive groups (RAAN Level 3).

Additionally, if you can smell smoke and see ash, the air may be even more unhealthy as the monitoring equipment doesn't pick up larger particles. SJVAPCD advises that if you see an area covered in ash, then you should assume the air quality is even more unhealthy (RAAN Level 4 or 5).

Currently, the SJVAPCD says that the following fires are impacting the Valley:

• The River Fire, south of Salinas in Monterey County
• SCU Lightning Complex, multiple locations throughout the NorthCoast Range
• The Lake Fire, southeast of Lebec in Los Angeles County
• The Hills Fire, west of Avenal in western Fresno County

Accordingly, everyone should take the appropriate precautions.
