Alamosa County tornado 8/16/08

Tornado strikes northeast of Alamosa...

Mid-afternoon on August 16th a strong supercell thunderstorm, which had already caused extensive crop damage in southern Saguache County, spawned a tornado northeast of Alamosa.  The tornado was witnessed by many, and occurred around 8 miles east-southeast of Mosca (2 1/2 miles south of San Luis Lake), in a rural area.  The tornado only lasted a few minutes, but, remarkably targeted and destroyed a structure...an unoccupied mobile home.
