This Day in Weather History: May 20
In 1951, heavy rain in Delta washed out trees, send boulders roaring down streets and poured a wall of mud and water 6 feet high over a highway for several hours. In 1975, one of the worst May snowstorms ever dumped 21 inches of snow on Fillmore and 20 inches at Delta. A foot of snow also shut down Payson and Santaquin.
