National Weather Service Denver/Boulder Colorado
941 am MDT Thursday Sep 12 2013
Update...major flooding/flash flooding event underway at this time with biblical rainfall amounts reported in many areas in/near the foothills. Precipitable water values in excess of an inch and a quarter on GPS sensors certainly support lots more rain today and tonight. 13z hrrr run has another 1-3 inches of rain predicted in the foothills through 04z so things are not looking good. Will extend the area of the Flash Flood Watch to include zone 43 and also extend it in time through 12z tomorrow morning.

These 24 hour rainfall totals are... well, I think they speak for themselves...
(I suspect the 1.69" is an error. Click image for a link to live, clickable data).
It's a mess here. Multiple roads closed. Reports of a truck-sized boulder on the bike path in Boulder Canyon. Boulder Valley Public Schools, University of Colorado, Naropa University, and all county offices are closed. I'm watching the rain continue to pour down from the safety of home today (in part because my main route and backup route to work are both closed, or at least were... information has been changing rapidly).
The Boulder County Sheriff has requested people stay off all roads in the county and "shelter in place" until the first responders have had a chance to deal with existing issues.
At least two small dams have broken in the area and at least one person has died when flood waters caused a structure in Jamestown to collapse. The entire town of Jamestown has been evacuated.
Update from a local email list:
"It is a dangerous situation everywhere! It was raining hard in Boulder and streets are flooded in low spots. Boulder Creek is now a raging river especially as you get closer to Boulder. Water is flowing across Hwy. 119 in numerous locations leaving behind debris and rocks on the highway. There are numerous rock and mud slides in the canyon up to Magnolia. It will only get worse if it keeps raining. Stay home and safe!"
