Just as a contrast to the heroic conditions braved by other forum members, I am a fair weather backpacker, usually confining myself to June through September when the weather in the Pacific Northwest is reliably moderate (or mostly so). The worst I've ever dealt with are some brief, but vigorous thunderstorms that dumped several inches of hail in a quarter hour and blew gusts up to a moderate 25 or 30 mph, some wet snowfall at night that melted by noon the next day, and a couple of multi-day bouts of steady, but quiet, rain with fog.

Nothing much, really. Certainly nothing dire. But don't get me wrong, I am not complaining.
