Much below average precipitation and above normal temperatures during April caused the snow water equivalent to drop from 90% of average on April 1 to just 40% of average on May 1. At the same time, observed April runoff was just 65% of average. These factors combined to reduce the forecast streamflows from 65% on April 1 to 50% on May 1.
