New records were set 'at several sncM courses on May 15. <br />Berthoud Summit broke the old record set in 1957 by 5.1 inches of snow water <br />equivalent. Many SNOTEL sites had shown an increase in water content by as <br />much as 1 1/2 inches during the first week of May. This increase waS followed <br />by an unseasonably warm period even at higher elevations. <br /> <br />The warm temperatures have induced snowmelt at all elevations, however, the <br />.lower elevations are melting at a faster rate and have contributed to the <br />majority of the higher streamflows. Many of the SNOTEL sites have been <br />averaging a melt of about 1/2-1 inch of water per day throughout the recent <br />warmer period. <br /> <br />Highest streamflow forecasts are on the Arkansas, Colorado, and Gunnison River <br />basins where the majority of streams are forecast to flow 40%-80% above <br />average this summer. Expected streamflow volume on the Arkansas above Pueblo <br />is nearly 75% above average for the April through September forecast period. <br /> <br />l.rEf~7 HEXICO <br /> <br />There were no manual snow courses measured on May 15, however, 5NOTEL readings <br />show a rapid melt at those sites with snow. The majority of sites had melted <br />out by mid May. Precipitation at most of the sites has been less than 1/2 <br />inch for the first half of May. <br /> <br />Nearly all of the major streams are forecast to flow above average this year <br />with the majority forecast at 35% to 50% above average. <br />
