Wildfire Smoke Information

Here you will find helpful information regarding wildfires, smoke and air quality affecting the Yolo-Solano Air Quality Management District and our recommendations to help families and residents lower their health impacts and overall exposure when wildfire smoke is present.

Below is a statewide fire map from CalFIRE. Zoom in and out using the + and – signs located at the bottom left corner. Click on a fire symbol in the map to learn more information about that specific fire.

Air Quality and Smoke Maps

If you would like to find additional websites with maps on air quality or weather, please click on any of the following buttons.

For the Purple Air Real-Time Sensor Map, please note that these sensors are a good way to track trends in air quality related to particulate matter, i.e. air quality is getting worse or better, and they provide a general idea of the PM readings in the area near the community sensor. However the sensors may register higher numbers than what the air quality actually is and readings from these sensors currently can’t be used for official pollution statistics/data.

Once you are on the website, type in your zip code or city and state in the search bar, located in the top left corner. Additionally when accessing this data, it is advisable to switch the option in the Map Data Layer dialogue box in the lower left hand corner from “None” to “AQandU”. This will apply a correction factor that will make the readings relate more closely to the official air quality data. You can also click on a specific colored circle for additional data.

Health Information

Wildfire smoke is made up of a complex mixture of gases, such as carbon monoxide, carbon dioxide, nitrogen oxide, and other organic chemicals.  Smoke also consists of fine particles, called particulate matter (PM), which can vary in size from visible specks to microscopic molecules. Particulate matter is the main pollutant of concern in wildfire smoke because of the short-term exposures usually experienced by the public. These small particles can bypass the body’s natural defenses and penetrate deep into the lungs.

Smoke can affect anyone, regardless of age, fitness level or health and those most sensitive to smoke include older adults, young children, women who are pregnant, and people with heart or lung disease and asthma. Exposure to such particles can lead to short or long term health effects.

Long term health effects can include: Short term health effects can include:
– Increased respiratory symptoms – Watery eyes
– Persistent cough – Headaches
– Decreased lung function – Shortness of breath
– Aggravated asthma – Coughing
– Irregular heartbeat – Irritated nose or throat
– Nonfatal heart attacks – Chest tightness

Wildfire Smoke Tips

The following tips and strategies can help families and individuals stay informed and lower their health impacts and exposure when wildfire smoke is present:

  • Reduce outdoor physical activity. Exercise increases the amount of air lungs intake by as much as 10 to 20 times, allowing pollution to travel deeper into the lungs.
  • Reduce exposure to smoke. Children, the elderly, women who are pregnant, and people with respiratory or heart conditions should be particularly careful to avoid exposure.
  • Lower other sources of indoor air pollution. Smoking cigarettes, using gas, propane and wood-burning stoves and furnaces, spraying aerosol cans and even burning candles or incense can increase particle levels in a home and should be avoided when wildfire smoke is present.
  • Pay attention to local news. Watch the news for health warnings as well as what to do in an emergency situation. Paying attention to public health messages is a measure residents can take to avoid smoke impacts and stay informed.
  • Stay indoos. Avoid outdoor activities regardless of health or fitness level. Smoke affects everyone.
  • Turn on your air conditioner and check your filters. Reduce exposure to outdoor smoke by closing all windows and doors and turning on the air conditioner. Consider visiting a place with air conditioning if no air conditioner is available and it is too warm to stay indoors. Run air-conditioners on the “re-circulate” setting, if available. A small percentage of newer homes have ventilation systems that actively bring in outdoor air. These should be turned off or set to a “re-circulate” mode. Do not run swamp coolers or whole house fans.
  • Check in with your health care provider. If you are having trouble breathing, seek medical assistance or call your primary care provider. People with asthma should follow their asthma management plan.

Air Quality Alerts and Social Media

It’s important to stay updated on information regarding air quality in your community. The following are some simple and easy ways to stay abreast of air quality conditions and find new or important information.

  • Sign up for EnviroFlash alerts. Receive local air quality alerts and forecasts via email or text messages at http://ysaqmd.enviroflash.org/. New users can choose which monitoring site is closest to them and what types of alerts of receive.
  • Follow the Air District online. Did you know the District has a Facebook and Twitter page? Stay informed of local air quality issues by following us on Facebook or Twitter
