HEALY, Alaska – Crews continue to secure the fireline on the Riley Fire. Due to higher resolution mapping, the fire size was determined to be 432, rather than 388 acres. Two hotshot crews secured the border around a large island of unburned vegetation within the fire. That additional line kept the percent of containment at 31%, even though the fire area is larger.

On Sunday, firefighters used unmanned aircraft systems (UAS) equipped with infrared sensors to detect heat signals in the interior of the fire. The UAS were able to identify remaining hot spots and pinpoint their location so that firefighters could extinguish them. Crews will continue this operation on Monday.

Weather: Cool and humid conditions are forecast for Monday, with the potential for isolated, light rain. Tuesday will be the start of a warmer, drier weather pattern.
