Colorado Smoke Outlook

COLORADO SMOKE OUTLOOK:
Saturday, September 21, 2019, 8:40 AM MDT

Lingering smoke from the Bald Mountain Wildfire in Jefferson County near Genesee will be possible throughout the weekend. Periods of light to moderate smoke will be possible at times near the fire and downwind, including in and around Genesee and Golden, however no significant health impacts are expected at this time.

The 885 acre Decker wildfire is located in northeastern Saguache County, approximately 8 miles south of Poncha Springs. Winds near the fire on Friday will primarily be out of the southwest. This will transport smoke to locations northeast of the fire. Winds will be breezy at times, possibly increasing fire activity and smoke production. This could bring periods of light to moderate smoke to Salida, Cleora, Wellsville, and Howard. Winds will likely remain primarily out of the west through Monday, though winds direction may oscillate, shifting to come from the northwest, west, and southwest at times. Winds may be also be breezy at times throughout the weekend. During overnight hours, light drainage winds may allow smoke to settle in locations below the fire, both to the south and southwest in northeastern Saguache County, and toward the east or northeast in western Fremont County. Areas with the best chance for smoke will be along and near US Highway 285, from Alder south to Villa Grove, and in areas of the Arkansas River Valley near State Highway 50 near Wellsville and Howard.

Prescribed burning operations may take place on Friday north of Red Feather Lakes in eastern Larimer County. Smoke from this burn will be visible in the area of Red Feather Lakes and from Highway 287 between Livermore and Virginia Dale. Light smoke is expected to be transported to the north or northeast of this area, remaining primarily in rural portions of Larimer County, just south of the Wyoming State line. Residual smoke production from smoldering fuels and continued operations on this prescribed burn may continue throughout the weekend. In this vicinity, unusually sensitive people should consider reducing prolonged or heavy exertion Friday through Monday.

Light to moderate concentrations of smoke are also possible near small wildfires and prescribed burns around the state.

What if there is a wildfire or smoke in your area?
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. Consider limiting outdoor activity when moderate to heavy smoke is present. 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.
