“Significant” rainfall is expected to move over Colorado ‘s largest active wildfire on Wednesday, and although the downpours could help slow the blaze's advance, fire officials are warning that the storms may also bring serious new dangers. The Aspen Acres Fire, burning about 10 miles northwest of Rye, Colorado, in Custer and Pueblo counties, has grown to 96,031 acres and was 15 percent contained as of Wednesday morning local time, the fire team told Newsweek in a daily briefing.
