HAZARD STATUS
Two Issues
1> Winter Storm & Temp Potential.
2> Full Winter Gear
The progression of the 2017 season's gear status change points began on September 15th, when Summer Gear was switched out for our Fall setup, three weeks earlier than this year.
This was followed up on November 3, 2017, when we brought out the
Winter Gear
Selection, which was two days later than this year, when Winter Gear was required on November 1.
Since that date different levels of Full Winter Gear have been Required, depending on the specific conditions.
We have reached the seasonal interface when temperatures can plunge to below zero.

Careful assesment of weather and gear is now critical to trip planning.
