An all-time 24-hour record rainfall of 9.08” (as of 6 p.m. 9/12 MT--almost double the previous record) has deluged the city of Boulder, Colorado resulting in widespread flash flooding and the deaths of at least three people so far. 12.27" has accumulated since Monday 5 p.m. (September 9th). Needless to say, these are numbers that surpass most tropical storm events. Other locations in the Boulder and Rocky Mountain Front Range have picked up over 11” of precipitation in just the past 24 hours. The official Colorado state record of 11.08" for a 24-hour period set at Holly on June 17, 1965 might be in jeopardy
