Flash flooding is the primary concern, especially in western and northern New Mexico and southwest Colorado. Urban areas, low-lying regions, and locations near rivers and streams are at the highest risk. Strong to severe thunderstorms could bring damaging wind gusts, large hail, and isolated tornadoes near the Four Corners region. Repeated rounds of rain over the same areas may exacerbate flooding risks. Snowfall in higher elevations could create hazardous travel conditions in mountainous regions.
