Despite a season of abundant spring rainfall and runoff in the Gunnison Valley, the late arrival of monsoon season has set the stage for fire, robbing the basin of the moisture it relies on each year to reduce the chance of starts. After nearly a month of little-to-no precipitation, the valley started registering drought conditions in mid-July. Lack of monsoon rains and high temperatures have exacerbated and prolonged the drying pattern, bringing drought back to the county and setting the stage for multiple fire starts around the Western Slope. Although a few storms have graced the valley recently, more significant precipitation is not expected for at least a week…

These lingering high pressure systems have ushered in record-breaking temperatures for both Gunnison and Crested Butte. Cities all over the Western Slope set temperature records this year, Sanders said. Thunderstorms that follow prolonged periods of drying tend not to bring “deep moisture,” he said. Dry air at ground level prevents moisture in the atmosphere from reaching the ground, causing dry thunderstorms. Fire officials have stated that the Lowline Fire burning north of Gunnison was likely started by a lightning strike, and most fires burning around the state have also been started this way. The high pressure system finally moved out in late July, bringing some moisture. Even then, rain fell in a few isolated incidents while darker storm clouds hung along the edges of the valley and didn’t quite make it into town.
