Classification of Weather Conditions

Thursday, October 29, 2009

They classify the weather around McMurdo Station to inform the residents what activities are allowed.  The following is paraphrased from the McMurdo Station Guide:

CONDITION 1:  Winds less than 48 knots, wind chills warmer than –75 degrees F., and visibility greater than 1/4 mile.  This is considered normal weather.

CONDITION 2:  One or more of the following – Winds between 48-55 knots, wind chills of  -75 to –100, or visibility less than 1/4 mile.  Requires check in & out with the Firehouse by radio prior to leaving town.

CONDITION 3:  One or more of the following – Winds greater than 55 knots, wind chills colder than –100, or visibility less than 100 feet.  Only “mission critical” travel permitted.  Stay in the building you are currently in until weather improves.

The airport went to Condition 3 this morning.  Here in town,  Mike & I haven’t seen anything worse than Condition 2.

I saw some other stats you might find interesting.  There are a little over 1000 people here at McMurdo Station. 73% male and 27% female.

McMurdo Station sits on Ross Island, which is about 45 miles long and 45 miles wide.

Mike and I get to go on a boondoggle on Sunday, so hopefully I’ll have a good story and some new pics.
