Weather Alert

The ‘Don’t’ Light Tonight’ season officially began November 1 and will run through the end of February.  This voluntary program asks Yolo-Solano Air Quality Management District residents to refrain from burning wood to help lower particulate matter in the air on days YSAQMD issues advisories.

The District will issue advisories asking residents not to use their wood stoves or fireplaces when particulate matter (PM 2.5) is forecasted to reach 25 micrograms or higher.  Areas covered in the advisories include all of Yolo County and a portion of Solano County, including Vacaville, Dixon and Rio Vista.

Residents can check the status of and view ‘Don’t Light Tonight’ advisories by:

  • Checking the District’s Facebook or Twitter account for advisories.
  • Signing up for the District’s EnviroFlash service at:http://ysaqmd.enviroflash.org/ and receive an email when an advisory is called.
  • Visiting the District’s website atwww.ysaqmd.org where ‘Don’t Light Tonight’ advisories will be posted.
  • Call (530) 757-3787 for a recorded message with the daily ‘Don’t Light Tonight’ status.

During winter months, the air can become stagnant and cooler temperatures aid in trapping air pollutants including particulate matter closer to the ground and the air we breathe. Wood smoke contains several toxic, harmful air pollutants including benzene, formaldehyde, carbon monoxide and fine particulate matter (PM.2.5).  PM2.5 is especially unsafe because its small size allows it to bypass the body’s natural defenses and travel to the heart, lungs and respiratory systems. Once present, PM 2.5 can trigger short term health effects like coughing and watery eyes and exacerbate existing conditions such as asthma.  Wood smoke can affect anyone, but those most at risk for serious health problems include young children, older adults and those with heart or respiratory problems.
