DigitalJanitor, Rune, and some others have it. Sometimes weather is an inconvenience one can prepare for. Sometimes it is something that one cannot carry enough gear to really handle as the possible conditions are very severe to the point of life threatening for the most prepared. Pushing on anyway in those conditions crosses over the line between adventure and stupid. I translate that to having and using a plan B or C and picking as appropriate. That might include changing trip dates depending on time of year and travel distances.
Free advice worth what you paid for it. ;-)
