Windslabs and windloaded open areas will still have to be managed carefully. Watch for shallow or hollow areas. Also, Tree-wells are still very rotted out and should be avoided.

Weather Forecast

A little bit of everything except spring. Some upper winds, more snow, clouds and clear breaks. Models vary, but it is reasonable to expect 10cm more snow on Friday, Next week we dip into some cooler temps and more snow, Hopefully we get some sun and warmer temps by the end of the week.
