One quarter of an inch of hail was on the ground after a hail storm hit on March 20, and then again on March 23.

A funnel cloud was spotted and photographed (see photo page) directly over downtown Crestone on April 24, and then briefly hit the side of the mountain, so officially it was a tornado. With this storm also came 1/2 inch hail stones in Baca Chalet One, sleet in downtown Crestone, yet no precip at all out in the Grants.
