April 16-22 is Severe Weather Awareness Week in Colorado. We are bringing you a series of tips each day so you can be prepared for the weather ahead. Tuesday's article is available here. NOAA All Hazards Weather Radio is another great way to monitor the weather and receive warnings. KiowaCountyPress.net and Plains Network Services in Eads will be giving away three weather radios at the end of the month - just stop by 1208 Maine Street in Eads to register to win.

Major flooding in September 2013 resulted from over eight inches of rain that fell over a large area from northern Jefferson County to the Wyoming border. This rain occurred in many creeks and rivers, causing considerable flash flooding. Runoff from area creeks combined to cause major flooding along the South Platte River. Mitigation is still ongoing to repair flood damage along the creeks and rivers in and near the foothills from Larimer County to El Paso County and along the tributaries to the South Platte River. 

Flash flooding refers to a dangerous sudden rise in water along a creek, river, or a normal dry land area.  Flash floods result from heavy rainfall, sudden breaks in river ice jams, and dam or levee failures.

Flash floods can occur within a few minutes or hours, and can move at surprisingly high speeds, striking with little warning.  Flash floods are quite destructive because of the force of the moving water, and the debris that accumulates in flood waters, such as trees and boulders, which can destroy roadways, bridges, and buildings.
Other complications in Colorado are recent fires which raise the flood threat when locally heavy rain falls on recent burn scars.   Residents in and near burned areas should plan on response actions for flooding.

The National Weather Service will discuss flood and flash flood potential in daily hazardous weather outlooks and in the weather story on National Weather Service websites. On days with a high threat of flooding you may hear:

A flash flood or flood watch, which means that flash flooding or flooding is possible within the watch area.

A flood warning, which means that flooding is imminent or has been reported along a river.

A flash flood warning, which means that flash flooding has been reported or is imminent.  When a flash flood warning is issued for your area, act quickly.  If advised to evacuate, do so immediately.  Go to higher ground or climb to safety before access is cut off by flood waters.

An urban flood advisory will be issued for impact flooding that is not in itself life threatening.  In an urban area if you were commuting during rush hour during a flood advisory you could expect some intersections to be underwater and a much longer commute.  A small stream flood advisory might be issued when the flow is bankfull with minor lowland flooding along the stream.
Nearly half of all flash flood fatalities are vehicle related.  Do not enter a flooded roadway, instead Turn Around Don't Drown.  In rapidly rising waters, backing up away from water may be safer.  One or two feet of water will carry away most vehicles and you also cannot tell if the road is damaged beneath moving water.

Stop by 1208 Maine Street in Eads to register to win one of three weather radios being given away by KiowaCountyPress.net and Plains Network Services. Entries close at 4:00 p.m. Friday, April 28, 2017.

Colorado Severe Weather Awareness Week continues through this Saturday.
