I’ve attached two weather updates.  A Flash Flood Warning for Larimer, Weld and Boulder County and a river update.  We are monitoring the St. Vrain River and Left Hand Creek.  Flows are listed below. 

Flash Flood Warning for Larimer, Weld, Boulder Counties, CO

Active for next 24 minutes · 

National Weather Service

This alert has been updated.

Posted 16 minutes ago

The Flash Flood Warning remains in effect until 10:15 pm MDT for Southeastern Larimer, Northeastern Boulder and southwestern Weld counties. At 9:19 pm MDT, the thunderstorm producing very heavy rain was located near Berthoud, or 19 miles south of Fort Collins, and was nearly stationary. Radar has indicated between 4 to 6 inches of rain has fallen halfway between Berthoud and Lyons with lesser amounts in the surrounding area between Riverside, Johnstown, Mead and hygiene. Runoff from the area with the heaviest rainfall will flow into Saint Vrain Creek between Lyons and hygiene and also on the little Thompson River southwest of Berthoud and produce flooding. Stream levels along Little Thompson River and Saint Vrain Creek could rise up very quickly.

Some locations that will experience flooding include: Southern Greeley, Longmont, Southwestern Loveland, Evans. Firestone, Johnstown, Milliken, Berthoud, Mead, Platteville. Lyons and Gilcrest.

The storm remains nearly stationary east of Lyons, north to Berthoud.  Around 2 inches of rain is possible in the warned area in the next couple hours.  This rainfall will exacerbate the flooding.

If you live in these areas follow these recommended actions.

Move to higher ground now. Act quickly to protect your life. This is becoming a very dangerous situation.

Excessive runoff from heavy rainfall will cause flooding of small creeks and streams, highways and underpasses. Additionally. Country Roads and farmlands along the banks of creeks, streams and other low lying areas are subject to flooding.




9:22 P.M. update

EOC open and staffed, our focus currently is on continuing the public information campaign and watching the rainfall over the St. Vrain drainage. 

Flood Warning issued until 9:00 tomorrow morning, 4 to 5 inches of rain has fallen in the Lyons area over the St. Vrain drainage.

No significant impacts to the City yet, the gauge at Lyons has risen 600 cfs in the last two hours.

Our concern at this point is flash flooding on the Lefthand and/or St. Vrain.  PD is monitoring both rivers.


Flood Information, Updates Can Be Found On City's Main Website

We will no longer be posting updates to the LongmontOEM.com which was used heavily during the flood emergency. We are transitioning from emergency response to relief and recovery. Any further communications over the next several months and years related to disaster assistance, infrastructure repairs, housing, and recovery of our community will be found on the city's main website at http://www.ci.longmont.co.us/flood-info/.

Thank you to the Longmont Community for all of your assistance for pulling together and overcoming adversity during the September Flood. The city has received many acknowledgements from the public on a "job well done". They are grateful for the city's planning and emergency response. Here are a couple of examples of the types of comments that we've been receiving.

"Thank you. Thank you all for how you are handling this flood disaster. Especially thank the OEM,public workers, police, firemen, city leaders, volunteers. Everyone, really, thank you. OEM seems to have handled this beyond well given the circumstances; preparedness has paid off. Longmont water, power, and government preparations and wisdom can be seen. I am glad we moved here two years ago, to a community that comes together in disaster instead of falling apart. That has plans and is prepared; that paid extra taxes and got things done ahead of time. A community that strives to support itself and provide for itself and others in their time of need. Thank you for keeping us all safe and working so hard. Thank you." ~ JP of Longmont

"As a resident of Longmont’s Southmoor Park neighborhood, I want to thank the City of Longmont’s Public Works and Natural Resources Department for the leadership and foresight they showed over the past two years in making improvements to the Left Hand Creek channel between 287 and Pike Road for the purpose of flood mitigation. While the damage to the Southmoor Park neighborhood was significant, the destruction of property would certainly have been far worse without these improvements (it removed 185 houses from the flood plain). I completely believe that these improvements saved my home, and my street from sustaining significant damage. Thank you all for your service to our community and for making Longmont such a great place to live! " ~ AM of Longmont

"Thank you very much for keeping our neighborhoods safe and for the quick response to clean them after the flood. It was amazing to see the City and the faith community work together to respond. Great work. " ~ KS of Longmont
