Weather Alert in Colorado
High Wind 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.

Weather Topic: What is Graupel?
Home - Education - Precipitation - Graupel
Next Topic: Hail
Graupel is a form of precipitation that is created by atmospheric conditions
which cause supercooled water droplets to contact snow crystals and freeze to
their surface.
Sometimes known as soft hail or snow pellets, graupel is delicate and easily
destroyed by touch. Whereas hail usually falls during severe weather, graupel
doesn't require such conditions to form, and can form in mild precipitation
similar to situations which produce snowfall.

A hole punch cloud is an unusual occurrence when a disk-shaped
hole appears in a cirrostratus, cirrocumulus, or altocumulus cloud.
When part of the cloud forms ice crystals, water droplets in the surrounding area
of the cloud evaporate. The effect of this process produces a large elliptical
gap in the cloud. The hole punch cloud formation is rare, but it is not specific
to any geographic area.
Other names which have been used to describe this phenomena include fallstreak hole,
skypunch, and cloud hole.
