A negatively tilted upper trough and associated cold front swung across the 4 Corners region and incorporated monsoonal moisture to produce strong thunderstorms with large hail and heavy rainfall across southwest Colorado. The runoff from this rainfall caused flash flooding in many areas, including locations around Durango. Hail damage to personal property in La Plata County was estimated to be at least two million dollars.
