Long Time Frame Flooding – Colorado Flood Safety and Wildfire Preparedness Week

Tuesday, March 9th, 2021 4:10am MDT

Floods and Flash FloodsFloods and wildfires are arguably the two most common disasters Coloradans face with numerous such events occurring each year.  To better prepare residents for the danger of these disasters, this week is Colorado Flood Safety and Wildfire Preparedness Week.

Each day this week the National Weather Service will be posting public information statements covering a number of different topics about floods and wildfires.  These important messages should be required reading for all Coloradans so they know what to do to prepare for these events and handle them when they occur.

ThorntonWeather.com will be posting each of these messages as a service to our readers.  Please check back daily for a new topic.

PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE PUEBLO CO
600 AM MDT TUESDAY MARCH 9 2021

Today’s topic during this Colorado Flood Safety and Wildfire Awareness Week is flooding which develops in the time frame of longer than 6 hours to several days. Floods in Colorado can result from snow melt, ice jams, a combination of snow melt and heavy rain, or just heavy rain. National Weather Service forecast offices in Colorado closely collaborate with regional River Forecast Centers that monitor the Colorado River, South Platte River, Arkansas River, and Rio Grande to come to a consensus on the likelihood of flooding along rivers and large creeks.

The National Weather Service will discuss flood potential in hydrologic outlooks, daily hazardous weather outlooks, and in graphical weather stories on National Weather Service forecast office websites.

Hydrologic statements may be issued for high flows that are within the banks of a river or large creek.

When flooding is possible on a river or large creek, a Flood Watch will be issued, meaning flooding is possible within the designated watch area.

When flooding is likely or occurring on a river or large creek, a Flood Warning will be issued, meaning flooding is expected or has been reported at designated river forecast points.

Flood Advisories may be issued for minor flooding on rivers and creeks.

An Areal Flood Warning may also be issued for flooding on a river or large creek in areas away from the designated river forecast points.

You can easily monitor potential flooding along rivers in Colorado and large creeks using the Advanced Hydrologic Prediction Service monitoring system. Information on this monitoring system can be obtained from this web site: https://water.weather.gov/ahps2

This monitoring system can be accessed on Colorado National Weather Service forecast office websites by clicking Rivers and Lakes.

At each river and large creek gauge you can easily look at current and forecast water levels, flood categories, historic crests, and flood impacts. Probabilities of exceedance of certain water levels by week or over the long term are also available.

In general, there will be some time to prepare for river and large creek flooding, and emergency management in your area has plans in place to address flooding issues. Know these plans and how you should act accordingly when Flood Watches and Flood Warnings are in effect.
