Around 10 million people remain under fire alerts in an area stretching from South Dakota down to Texas and Arizona on Sunday afternoon.
Wind gusts as high as 30-40 mph, combined with warm temperatures, dry vegetation and relative humidity values as low as 5%, are expected to create hazardous conditions for the development of new fires. San Antonio, Texas; Colorado Springs, Colorado; Santa Fe, New Mexico; and Tucson, Arizona, are among the areas at risk.
