The contiguous United States experienced its warmest June-August on record in 2026, accompanied by below-normal precipitation and above-normal temperatures that sustained widespread drought, now covering nearly half the country. These extreme conditions fueled a destructive wildfire season that sent unhealthy levels of smoke streaming through large parts of the United States. Major western

Flash drought can develop quickly, sometimes transforming relatively normal conditions into significant drought in just a few weeks. That rapid development makes flash drought detection particularly challenging in the Southeastern United States, where frequent rainfall can be followed by short periods of intense heat and little precipitation.That challenge is especially evident during the growing

When drought intensifies, decisions cannot wait. Ranchers decide when to move livestock, water managers balance reservoir operations, and emergency managers coordinate drought response. Yet the information guiding those decisions is often scattered across multiple websites, difficult to compare, and challenging to translate into action.To help close that gap, the Montana Climate Office has
