DENVER, Colorado — Cloud seeding can provide between 5% and 15% more snow to help ski areas, farmers and watersheds in the state, supporters say. "These observations show us that cloud seeding does work," said University of Colorado researcher Katja Friedrich, who has studied cloud seeding inside and outside of a laboratory. She worked with scientists who flew planes near moisture-rich clouds and injected them with silver iodide, a substance that causes moisture to become heavy and fall to the ground as snow. On a radar image, she pointed outlines of snow that later formed. The visible lines matched the pattern the cloud seeding plane had flown in the sky. Cloud seeding in Colorado aims to produce more snow, not rain. Friedrich said it's difficult to quantify how much additional snow is created. Cloud seeding doesn't make more clouds, but supporters believe it gets more snow out of an approaching storm. Planes can be used to seed approaching storm clouds. Ground seeders use propane to heat the air and also used in the mountains and Western Slope. Silver iodide is then added to the warmed air as it rises. The moisture, already in the clouds, bonds to the silver iodide. When it becomes heavy, it falls to the ground as snow. Cloud seeding has been happening for about 70 years in Colorado but is slowed in years when there is heavy snowfall. Cloud seeders operated during the 2018-2019 winter but slowed in places where significant snowpack accumulated. A man who owns a cloud seeding company on the Western Slope said the technology works well. Cloud seeder's viewpoint Cloud seeders dot highpoints in Colorado from the west to central part of the state. Ski areas hire Eric Hjermstad's Western Weather Consultants company to cloud seed early in the season, so there's more natural snow before opening day. He continues seeding until mid-April. He showed off a cloud seeder located at a recreation site north of Leadville. He can remote start the seeder, turn on the propane flame and add the silver iodide. 2040

My heart breaks this morning at the loss of NBC audio technician Larry Edgeworth (pictured right) due to COVID19. I adored Larry. We traveled together for two straight months on a campaign in 2008 and he was always the most warm, most professional, most loving. All hours of the day and night, no matter how hungry or tired or stressed we were - he was always a joy. He loved his work and excelled at it. He loved his colleagues and boy did we love him. Larry, dear, I will miss you. My deepest condolences and prayers to his family. 549

For 52 years, Tom Hollett has been scanning the water as a lifeguard. But being a lifeguard in Vancouver, Canada means he also keeps watch over frozen water. “I'd rather make 10,000 rescues in the warm ocean than one here,” Hollett says of the frozen lake.This part of Canada, nestled between the Pacific Ocean and the North Shore Mountains, it’s the only part of the country where the average temperature stays above freezing, even in the winter. So, when the lakes start to freeze over, it’s a novelty. The lake attracts visitors, who are often tempted to tread on the thin ice, often times with their pets. “There’s people that don't understand the ice, so they just figure they can walk on it,” Hollett says. When temperatures are colder, as they have been this week, the City of Vancouver Parks and Recreation department dubs a few of their summer lifeguards, "iceguards." "Lifeguards are always scanning and keeping an eye out, so that's what our iceguards do,” Sean Healy with the Vancouver Board of Parks and Recreation says. “When they come out to iceguard, they actually do a walking patrol around the lake. They also keep binocs close at hand.”Hollett says he’s had to make ice rescues before for people’s pets. “Believe it or not, I’ve saved many dogs,” he recalls. “I grabbed their collar like this, reach out and bring ‘em up in the ice." 1369
