While that may not be very surprising, the location of the record is.
Weather experts announced Monday that they've confirmed that 11.85 inches of rain fell over 24 hours at a rain gauge at Fort Carson on Sept. 12, 2013. More than two-thirds of that fell in over just three hours.
While northern Colorado had more total rain over a larger area in September, state climatologist Nolan Doesken says no official record is kept for most rainfall in a week.
The new proposed record breaks the previous one-day, official rainfall total of 11.08 inches in Holly in 1965.
The National Climate Data Center must approve the new record before it goes into the books.
