COLORADO SMOKE OUTLOOK:
Friday, July 25, 2014, 2:00 PM
Areas of moderate to locally dense smoke are possible on Friday and Saturday near and to the north and east of the Alkali Fire located 14 miles north of Maybell in Moffat County. A shift to more westerly winds near the fire on Saturday could bring smoke eastward across northern Colorado, including to the Front Range Urban Corridor.
Several other wildfires in the western United States could contribute areas of haze and smoke to parts of Colorado at times through the weekend.
There are no Wildfire Smoke Health Advisories in effect in Colorado at this time.
Light to moderate smoke is also possible near prescribed fires and small wildfires around the state.
What if there is a wildfire or smoke in your area that is not reported above?
The focus of the Colorado Smoke Outlook is on large fires (e.g., greater than 100 acres in size). Nevertheless, smoke from smaller fires, prescribed fires, and/or smoke from new fires not yet known to CDPHE air quality meteorologists may cause locally heavy smoke. If there is smoke in your neighborhood, see the public health recommendations below.
Public health recommendations for areas affected by smoke:
If smoke is thick or becomes thick in your neighborhood you may want to remain indoors. This is especially true for those with heart disease, respiratory illnesses, the very young, and the elderly. Fine particulates may reach the Unhealthy category where smoke is heavy. Consider limiting outdoor activity when moderate to heavy smoke is present. People with heart or lung disease, older adults, and children should avoid prolonged or heavy exertion; everyone else should reduce prolonged or heavy exertion. Consider relocating temporarily if smoke is present indoors and is making you ill. IF VISIBILITY IS LESS THAN 5 MILES IN SMOKE IN YOUR NEIGHBORHOOD, SMOKE HAS REACHED LEVELS THAT ARE UNHEALTHY.
