<br />!"" ... <br />,- <br /> <br />Colorado are generally higher than normal for this time of year. This condition developed because of <br />. reservoir operations in anticipation of below average snowpack earlier this year. <br /> <br />. <br /> <br />. <br /> <br />4) LANDSLIDES, ROCKSLIDES, AND DEBRIS FLOWS <br />The Colorado Geological Survey presented information about various geological hazards throughout the <br />state. There seems to be a higher Occurrence of slides in certain parts of Colorado this year. The CGS is <br />working with other agencies on the 1-70 landslide east of Grand Junction and on other problem areas. <br />Garfield County, Mesa County, and Clear Creek County are specific areas of concern at this time. The <br />Colorado Department of Transportation is working hard to keep roadways open and to clean up and <br />mitigate the effects of slides when they impact state highways. The current conditions exist due to the <br />seasonal nature of freeze-thaw cycles, wet and dry periods, and the general precipitation conditions over the <br />past three years. <br /> <br />5) COLORAD CLIMATE <br />The Colorado Climate Center (CCC) provided a big picture perspective on how this year is shaping up, <br />weather wise, compared to previous years. It looks as though 1998 is similar in nature to 1983. We are <br />now on the way out of an EI Nino year, and this should have some impacts to our weather patterns. <br />Southeast Colorado, in particular, may see some flooding problems in June due to widespread, large general <br />rainstorm events. Traditionally, northeastern Colorado is more at risk for those large June events, but this <br />year may be different. <br /> <br />John Henz and Nolan Doesken presented some interesting information about this year's "polar cold cell." <br />At this time, there is a singular large cold cell (northern hemisphere) that has not broken up yet. The Task <br />Force will be monitoring the polar cold cell, as it has specific impacts on our weather patterns and <br />precipitation events as we move into summer. <br /> <br />Additionally, the CCC mentioned that the period from May 30 through June 12 historically has a very high <br />incidence of tornado activity in eastern Colorado. <br /> <br />6) FUTURE MEETING OF THE TASK FORCE <br /> <br />Next Task Force meeting is Friday, June 5,1998 at 9:00 AM <br /> <br />Location: <br /> <br />US F&WS Building <br />655 Parfet, 3rd Floor <br /> <br />fnfonnation in this report is a compilation of materials from presentations of the "The Colorado Task Force", Lany Lang, Chair. <br />Colorado Water Conservation Board.
