<br />,> <br /> <br />THE PURGATORY SKI AREA -UPPER HERMOSA, DOLORES AND LA PLATA RNER <br />DRAINAGE BASINS WEATHER MODIFICATION PROGRAM <br /> <br />The 2000-2001 winter season weather pattern over the Western United States returned to a <br />more nonnal sequence of weather systems resulting in only slightly below nonnal precipitation <br />over the region. The first half of November was quite wet with frequent systems moving through <br />the Western San Juan Region, The last half of November and into early December were well <br />below nonnal in snowfall from minimal infrequent weather systems. <br /> <br />The two weeks prior to Christmas saw a return to frequent and ample snowfall from five <br />stonn events that moved through the San Juan Mountains. The end of December and nearly the <br />first two weeks of January had a return to more fair skies and little additional snowfall with no <br />seeding opportunities, <br /> <br />The weather patterns again changed to allow a succession of six weather systems to move <br />through the legion during the remainder of January. The wide swings from wet periods to <br />extended dry periods of weather, coupled with several of the wetter stonns hitting only the <br />southern San Juan Mountains, left the Western San Juan's with near nonnal precipitation along <br />the Southern face and near 80 to 90 % of nonnal precipitation in the high country and along the <br />Northwestern Basins as the seeding season ended, <br /> <br />Western Weather Consultants has completed its first season of a 5-year Cloud <br />Seeding Pennit for the Western San Juan Mountains that was issued in November 2000. <br />
