Monday November 19 through Tuesday November 20, 2018

The Public Health Departments of Yuba and Sutter County and the Feather River Air Quality Management District are extending the joint air quality health advisory to notify the public of continued unhealthy air quality conditions caused from wildfire smoke from the Camp Fire in Butte County.

The Air Quality Index levels for Monday November 19 and Tuesday November 20 are forecasted to be Unhealthy for Yuba and Sutter counties.  Light and variable winds will reduce dispersion and allow smoke to linger.  Overnight temperatures will limit mixing and trap the smoke near the ground. On Wednesday as the cold front approaches the southeasterly winds should push the smoke from the Camp Fire out of our area, but will also transport smoke from the southern Sacramento Valley and San Joaquin Valley into our region.  Therefore the forecast for Wednesday is Unhealthy for Sensitive Groups. By Thursday the storm should clear most of the smoke with strong southerly winds.  Even with this storm system, as long as the Camp Fire is generating smoke the Yuba Sutter area may experience periods of smoke impacts, though not as prolonged and extreme as the past 10 days.

Smoke density can vary widely from one local area to another and also with time of day.  “Air quality conditions depend on a number of factors, which include proximity to the fire, wind speed and direction, and whether inversions are present,” warns Christopher D. Brown, Air Pollution Control officer. 

You can check current conditions online at www.airnow.gov or www.sparetheair.com.  Residents can also sign up for air quality forecasts and alerts at www.fraqmd.org. Residents who see or smell smoke should consider these precautionary measures:

·   Remain indoors and keep windows and doors closed as much as possible. 

·   Use the recycle or recirculate mode on the air conditioner in your home or car.

·   Avoid the use of non-HEPA paper face mask filters which are not capable of filtering extra fine particles.  Do not rely on HEPA face mask filters to do unnecessary outdoor activities.

·   Keep airways moist by drinking lots of water.  Breathing through a warm, wet washcloth can also help relieve dryness, but does not filter out the hazardous smoke particles.

·    Avoid the fire areas.

·   Avoid burning wood in woodstoves and fireplaces, and avoid other activities that cause particulates to become airborne such as vacuuming or dusting.

Wildfire smoke may contain particulate matter, ozone, carbon monoxide, and toxic air contaminants.  While all persons may experience varying degrees of symptoms, more sensitive individuals, such as the young, aged and those with respiratory conditions are at greatest risk of experiencing more aggravated symptoms.  Symptoms may include, but are not limited to, coughing, watery and itchy eyes, and difficulty breathing.  Persons experiencing questionable or severe symptoms should seek professional medical advice and treatment. 

The District has partnered with the California Air Resources Board to install low-cost particulate matter sensors in several Yuba and Sutter County locations such as Sutter, Yuba City, Robbins, Wheatland, and Oregon House.  These sensors are not as accurate as the permanent or temporary monitoring stations; however the data is available online in real time and can show trends such as whether an area is likely to experience increasing or decreasing smoke levels.  The maps can be accessed at: https://www.purpleair.com/.

County officials will continue to monitor air quality in Sutter and Yuba County and provide updates on this advisory as needed.  For current information, or to sign up for air quality alerts and forecasts, go to the Feather River Air Quality Management District website http://www.fraqmd.org/ or check the Sutter County and Sutter County Public Health Facebook pages or Yuba County website.
