Lookout Posted October 29, 2012 Share Posted October 29, 2012 That is a lot of snow. I see the local NWS is saying 1-2 feet so I am guessing this is somewhat overdone. NWS is actually forecasting up to 3 feet, maybe more, in parts of the higher elevations of wv. Combine that with 60mph plus winds they are forecasting and the fact it will be a heavy wet snow, you can't help to believe damage will be severe.

BlizzardWx Posted October 29, 2012 Share Posted October 29, 2012 NWS is actually forecasting up to 3 feet, maybe more, in parts of the higher elevations of wv. Combine that with 60mph plus winds they are forecasting and the fact it will be a heavy wet snow, you can't help to believe damage will be severe. I must have missed something then. Either way it looks to be quite a bit of wet snow, and maybe even briefly rain as the storm pushes inland. That much wet snow, with strong winds is as you say, troubling.

BeauDodson Posted October 29, 2012 Share Posted October 29, 2012 I must have missed something then. Either way it looks to be quite a bit of wet snow, and maybe even briefly rain as the storm pushes inland. That much wet snow, with strong winds is as you say, troubling. With the amount of moisture in the snow - lot of compacting. I would imagine once it gets above a certain depth that you will see quite a bit of compacting. We had a storm back in the 1990s (southern IL) that produced about 8-10" of wet snow. It compacted after a few hours down to 5-6 inches. Not exactly sure how one figures that into the equation. We shall see. I would be concerned about roof collapses. Lot of weight. Link to comment Share on other sites More sharing options...
