CPSWS 2014 - The Record-Breaking Colorado Floods of September 2013
An exceptionally prolonged rainfall event across the Front Range of Colorado produced record single- and multi-day totals at a number of stations. A total of 9.08 inches of rain was measured in Boulder for the 24 hours ending at 6 p.m. MST on 12 September. In some cases, the estimated recurrence interval for this amount of rainfall is more than 1,000 years. These rains produced record floods and severe damage within the St. Vrain and Big Thompson watersheds, with major damage also reported along smaller creeks in and near Boulder.
