Whoa! The areas around McMurdo have hit condition 1 because visibility dropped below 100 feet. Condition 1 is defined as weather that meets any of the following criterion or combination of criteria:
wind speeds greater than 55 knots
wind chills colder than -100 degrees Fahrenheit
visibility less than 100 feet
I actually had to put on my goggles for the first time today so that stuff wouldn't get in my eyes.
