There's absolutely no reason to not install gutters in an extreme climate (ask any Canadian).
People are generally fearful of ice dams building up, but this doesn't happen if you have proper ventilation in your attic and soffits, and your ceilings are insulated (floor of attic--can use batts or "blown in" loose fiberglass). Winds should not be a problem either if gutters are installed properly, I've lived through gale and hurricane force winds up and down the west coast as well as here in on the edge of the prairie/Rocky Mountain foothills and never seen gutter damage due to wind. You do need to clean the leaves out every fall if your trees drop leaves into your gutters or you'll have problems.
Southern Alberta, where I live, gets heinous freeze/thaw cycles for 6 months of the year because we get warm Chinook winds roaring down from the Rockies every couple of weeks all winter long. It snows, it gets COLD (mid -30 C/-22 F), we get a Chinook and some melting, it freezes again, it snows some more (even when the temps are in the -20s C), it melts--all winter long.
Northern Alberta and most of the prairies just get cold, snow, and more cold all winter long. Everywhere on the Canadian prairies gets wind, and lots of it. Everyone has gutters on their homes, and ice dams are rare, and ALWAYS related to poor insulation/ventilation of the attic space.
There is a lot of outdated misinformation about gutters out there, don't listen to old-timers who tell you gutters won't work in your climate. Gutters prevent runoff damage to your landscape and completely eliminate dangerous icicles hanging off your roof. Downspouts can direct water into rain barrels, flower beds, and to the base of trees--saving water.
