I agree with mkirsch vis snow (and, ice!) accumulation on these "Tempo" plastic sheet / metal tubing structures. We have thousands of these things collapse every winter in Quebec (similar snowfall to the Lake Ontario northern New York snow belt).
From what I am seeing in the most recent ENSO diagnostic discussions, the strong/steady easterly (high and low streams) atmospheric coupling to fast sea surface temp increases in el nino 3 region looks poised to deliver warmer temps this coming winter. This really worries me, because when this set-up happens, the Northeast regions of North America may get more ice and rainfalls than snow (read: extremely heavy loads; not light powder snow). The next diagnostic discussion will happen on the 17th.
IF Ontario, Quebec and New England get hit with severe ice storms this winter, it won't bode well for outdoor RV/truck camper storage (read: falling trees, branches, ice, and lots of other similar hazards!). Our entire rig (truck and camper) will be stored indoors this winter, particularly.
