Weather Alert in Colorado
Blowing Dust Warning issued February 17 at 12:52PM MST until February 17 at 5:00PM MST by NWS Goodland KS
AREAS AFFECTED: Yuma County; Kit Carson County; Cheyenne County; Cheyenne; Sherman; Thomas; Wallace; Logan; Gove; Greeley; Wichita
DESCRIPTION: * WHAT...For the Blowing Dust Warning, several plumes of dust are ongoing across the warned area. Brownout conditions are expected near these plumes extending several miles downstream of the source region. For the High Wind Warning, west winds 35 to 45 mph with gusts up to 65 mph. * WHERE...Portions of east central and northeast Colorado and northwest and west central Kansas. * WHEN...Until 5 PM MST /6 PM CST/ this afternoon. * IMPACTS...Severely limited visibilities are expected. Travel will be dangerous and possibly life-threatening. Poor air quality may cause issues for people with respiratory problems. High winds may move loose debris, damage property and cause power outages. Travel could be difficult, especially for high profile vehicles. Plumes of blowing dust will create pockets of low visibility. Visibilities will likely change rapidly over short distances, making travel hazardous in these areas. * ADDITIONAL DETAILS...Be especially cautious near open fields in areas where the wind is perpendicular to the road. These locations are especially vulnerable to significant dust plumes and should be approached with extreme caution. If possible, avoid travel until winds subside.
INSTRUCTION: Blowing dust can significantly lower air quality and it is encouraged that you take preventative measures such as staying indoors or wearing protective breathing masks if outside. High dust concentrations can cause respiratory problems, decrease lung activity, aggravate asthma, and lead to potential heart-related problems, especially with children, elderly or those with pre-existing respiratory conditions. Be ready for a sudden drop in visibility to near zero. If you encounter blowing dust or blowing sand on the roadway or see it approaching, pull off the road as far as possible and put your vehicle in park. Turn the lights all the way off and keep foot off the brake pedal. Remember, 'Pull Aside, Stay Alive'. Be prepared for a prolonged period of poor air quality due to blowing dust. Fasten loose objects or shelter objects in a safe location prior to the onset of winds. Winds this strong can make driving difficult, especially for high profile vehicles. Use extra caution.

Cumulus clouds are fluffy and textured with rounded tops, and
may have flat bottoms. The border of a cumulus cloud
is clearly defined, and can have the appearance of cotton or cauliflower.
Cumulus clouds form at low altitudes (rarely above 2 km) but can grow very tall,
becoming cumulus congestus and possibly the even taller cumulonimbus clouds.
When cumulus clouds become taller, they have a greater chance of producing precipitation.

Evaporation is the process which returns water from the earth
back to the atmosphere, and is another crucial process in the water cycle.
Evaporation is the transformation of liquid into gas, and it happens because
molecules are excited by the application of energy and turn into vapor.
In order for water to evaporate it has to be on the surface of a body of water.
