What's with the hazy skies over Tucson?

Posted: Updated:

TUCSON - Smoke from wildfires in the Pacific Northwest is affecting several western states, including Arizona.

The Pima County Department of Environmental Quality is not issuing an air quality advisory at this time. Monitors are currently recording particulate levels in the lower moderate range.

According to 4WARN Meteorologist Jeff Beamish, high pressure parked over the Great Basin has been drawing in the smoke over the last several days.

There is a chance of rain on Friday, which could help reduce the smoke. As long as the wildfires continue to burn, there will be the potential for hazy skies and elevated particulates.

Most individuals will not be affected by current air pollution levels. Unusually sensitive people, including individuals with heart disease and respiratory sensitivities, may want to consider reducing prolonged or heavy outdoor exertion to decrease the amount of particulates they breathe into their lungs. Small particles can travel into the respiratory system and cause short-term health effects such as eye, nose, throat, and lung irritation, coughing, sneezing, runny nose and shortness of breath.

Those most at risk may feel better if they avoid outside exercise, stay inside as much as possible, and keep windows and doors closed to help reduce exposure to particulate matter.

Particulate matter can be made up of tiny specks of soot, dust, smoke and aerosols that are suspended in the air we breathe. Particulate matter can come from dust from disturbed land that becomes airborne with high winds and also from combustion sources such as cars, industry, and indoor and outside fires.
