Mexican radio amateurs have been providing communication support from a fire scene in a remote area to civil protection authorities in Monterrey, Mexico. Two-member teams of volunteers have been flown in via helicopter since May 20, the first day of radio support, when the fire had already been burning for a couple of days. The fire in Pajonal — about 20 kilometers south of Monterrey — covered more than 200 acres in rough terrain. Temperatures have topped 100 °F.
Fueled by hot and dry conditions, Mexico’s 2019 fire season has been intense, leading to poor air quality. As of mid-May, more than 100 wildfires were active in 17 Mexican states.
