* WHEN...12 PM Monday through 6 PM Tuesday.

* IMPACTS... Particle pollution can get deep into the lungs and
cause serious health problems such as asthma attacks, heart and lung
disease symptoms, and increased risk of lung infections. Everyone
can be affected, but sensitive groups such as people with lung or
heart disease, older adults, people who are pregnant, children, and
those who spend a lot of time outdoors are at greater risk.

* When Air Quality Index (AQI) levels are "Unhealthy for Sensitive
  Groups" (orange), sensitive groups as specified above should
limit
  extended or intense outdoor activity.
* When AQI is "Unhealthy" (red), everyone may experience health
  impacts. Sensitive groups should avoid extended time outdoors.
* When AQI is "Very Unhealthy" (purple), sensitive groups should
avoid
  all outdoor physical activity. Everyone else should avoid
extended
  or intense outdoor activity.
* When AQI is "Hazardous" (maroon), everyone should avoid all

* Keep windows and doors closed
* Run your air conditioner and/or an air purifier
* Do not use whole house fans or swamp coolers that bring in
outside
  air if you have other methods to stay cool
* Avoid other sources of pollution such as fireplaces, candles,
  incense, grilling, and gasoline-powered lawn and garden equipment

To help minimize outdoor particle pollution levels:
