Weather Alert in Texas
Blowing Dust Advisory issued March 14 at 1:32AM MDT until March 14 at 8:00PM MDT by NWS Midland/Odessa TX
AREAS AFFECTED: Davis Mountains
DESCRIPTION: * WHAT...For the High Wind Warning, west winds 40 to 50 mph with gusts up to 75 mph expected. For the Blowing Dust Advisory, visibility between one-quarter and one mile in blowing dust expected. * WHERE...Davis Mountains. * WHEN...For the High Wind Warning, until 7 AM CDT Saturday. For the Blowing Dust Advisory, from 7 AM this morning to 9 PM CDT this evening. * IMPACTS...Hazardous driving conditions due to reduced visibility. In addition to reduced visibility, strong winds will be hazardous to trailers and other high-profile vehicles. Travel will be difficult, especially for high profile vehicles like campers, vans, and tractor trailers. Aviation interests may experience localized but extreme turbulence, or strong downward airflows if flying in the near the Guadalupe Mountains. Severe turbulence near the mountains will be hazardous for low flying light aircraft.
INSTRUCTION: Persons with respiratory problems should make preparations to stay indoors until the storm passes. 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'. Slow down, use low-beam headlights, and leave plenty of distance between you and other vehicles. Winds will be particularly hazardous at higher elevations where the strongest winds are likely to occur. Be especially careful driving in these mountainous areas. People driving high-profile vehicles should strongly consider postponing travel in these areas until the winds subside. Use caution if flying low near the mountains as severe turbulence is possible. Use caution when driving as blowing dust may reduce visibility.

Next Topic: Condensation
Cirrus clouds are high-level clouds that occur above 20,000 feet
and are composed mainly of ice crystals.
They are thin and wispy in appearance.
What do they indicate?
They are often the first sign of an approaching storm.

A contrail is an artificial cloud, created by the passing of an
aircraft.
Contrails form because water vapor in the exhaust of aircraft engines is suspended
in the air under certain temperatures and humidity conditions. These contrails
are called exhaust contrails.
Another type of contrail can form due to a temporary reduction in air pressure
moving over the plane's surface, causing condensation.
These are called aerodynamic contrails.
When you can see your breath on a cold day, it is also because of condensation.
The reason contrails last longer than the condensation from your breath is
because the water in contrails freezes into ice particles.
