<br />-, <br /> <br />~ ~ ~ <br /> <br />time. Additional heavy snowfall amounts during the remainder of <br />November and early December kept the snow pack in excess of the <br />operational seeding criteria. On January I, 1986, snowcourse reading in <br />the seeded area dropped below 150% of average and operational seeding <br />resumed through February 6, 1986. <br /> <br />The weather pattern this winter was basically characterized by extended <br />periods of heavy precipitation followed by prolonged periods of no <br />precipitation. This type of weather pattern, along with the additional <br />concerns for avalanche conditions, greatly limited the ability of the <br />program to prOVide seeding operations for many of the weather events <br />having precipitation augmentation potential. <br /> <br />During the period November 17, 1985 through February 24, 1986, WESTERN <br />WEATHER CONSUL T ANTS, INC. seeded five selected weather events <br />covering portions of seven days. The operations for the San Juan program <br />amounted to 200.25 hours of generator seeding time, which dispensed <br />1925.00 grams of si Iver iodide. <br /> <br />The following table lists the individual seeding events and gives the <br />number of generators operated, the total number of seeding hours, the <br />seeding rate, and the total output of silver iodide in grams. This table is <br />followed by a presentation of precipitation events to seeding events. This <br />presentation is provided for informational purposes only; no Quantitative <br />statistical evaluation of the seeding effects from this program will be <br />attempted. <br />
