This week is Flood and Wildfire Awareness Week in Colorado. The National Weather Service offices in the state, and KiowaCountyPress.net - a Weather Ready Nation partner - are bringing you a series of articles this week to help you improve your safety and preparedness. Monday's article provided a look at flood watches and warnings Colorado.
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.
