National Weather Service forecasters have identified a Red Flag Warning for Yellowstone National Park and the Absaroka Mountains to the east. They designated the park boundary and the Wyoming/Montana state line as the edge of the extreme weather and fuel conditions on three sides. Apparently the national forests and the park on the north, west, and south sides of Yellowstone are not affected.
The Red Flag areas are confined to Fire Weather Zones 140 and 236. Zone 140 is Yellowstone NP, which has mostly straight lines on three sides. Zone 236 is the Absaroka Mountains.
This is the only area in the United States under a Red Flag Warning today.
Meanwhile the U.S. Forest Service forecasts mostly Moderate to High fire danger for the same area.
The Red Flag map was current as of 8:40 a.m. MDT on Sunday. Red Flag Warnings can change throughout the day as the National Weather Service offices around the country update and revise their forecasts and maps. For the most current data visit this NWS site.
