This was a post in our staff folder today.
"Changed the Cold Weather Travel to use the New Wind Chill Temperature Chart: Student travel will not be allowed at temperatures below –30 degrees Fahrenheit except by jet. Ground travel (car, snowmachine) by students between villages will not be allowed if the temperature including chill factor is below –25 degrees Fahrenheit. Air travel (expect by jet) by students will not be allowed if the temperature including chill factor is below –35 degrees Fahrenheit. http://www.lksd.org/board/actions0102.htm"
I guess Yahoo said that the wind chill in Bethel is -47 now.
