The remnants of Tropical Storm Ivo, off the coast of Baja, are pumping tropical moisture into the Southwest.

Tropical storm off Baja pumping moisture into Southwest

By Summit Voice

FRISCO — So far, the Atlantic hurricane season hasn’t been particularly active, but in the eastern Pacific, nine named storms have formed, most of them moving out to sea with little impact to land areas.

But the latest in the series, Tropical Depression Ivo, is dawdling off the west coast of Baja California and sending moisture streaming into northwestern Mexico and the southwestern U.S. The moisture could affect much of western Colorado and eastern Utah Sunday and Monday, with another round of heavy thunderstorms possible.

Monsoon rains brought above-average moisture to Summit County in July.

By Bob Berwyn

FRISCO — July brought above-average moisture to both official National Weather Service sites in Summit County, especially in Dillon, where the monsoon delivered 3.35 inches of water, about 1.47 inches more than average for the month.

At least a trace of precipitation was reported on all but seven days at the Dillon weather observation station, with the wettest days on July 25 and July 26, both delivering about a half inch of moisture.

The average daily maximum temperature at Dillon during July was 74.4 degrees, just .10 above average, but the daily average low temperature was 39.8 degrees, nearly 4 degrees above average, probably due in part to plentiful nighttime cloud cover. Continue reading

FRISCO — Flashes of lightning, loud thunder and heavy rains Friday marked the start of Colorado’s summer monsoon season. The one- to 2-month period when moist and warm air flows northward from the subtropics may not be as dramatic as the Asian monsoon, but it’s still a critical piece of the state’s overall weather picture, providing abundant moisture just at the time when forests and fields are reaching their driest point.

FRISCO — June, the second-driest month in Summit County, ended up especially dry this year, with only 0.26 inches of precipitation at the official National Weather Service site in Breckenridge, and even less — 0.19 inches at the Dillon station.

Averages for the two sites are 1.37 inches in Breckenridge and 1.14 inches at Dillon, where there was measurable precipitation on two days, June 18 and June 29.

The sparse total in Breckenridge made it the fourth-driest (tied with 2006) on record, dating back more than 100 years, said weather observer Rick Bly. The driest June ever (0.06 inches) was in 1980, during another notable Colorado dry spell, followed by June 1891 (0.10 inches) and June 2002 (0.24 inches). Continue reading

FRISCO —Even the drive-by spots in Summit County are just littered with wildflowers these days, and some of the best spots to look are in some of the areas that were clear-cut a few years ago. Bright sunlight and plenty of moisture this spring have spurred an amazing variety of flowering plants where there was once only pine tree litter. Meanwhile, the sky was putting on its own show, preparing to fire up a nice round of thunderstorms. Continue reading

Denver Water eases watering restrictions

Spring snow and rain helped boost reservoir storage

Dillon Reservoir is about as close to full as it’s going to get this year.

By Summit Voice

SUMMIT COUNTY — Just a day after the Colorado Water Conservation Board described lingering drought conditions across much of Colorado, Denver Water eased watering restrictions, saying that the city’s water supply situation has “greatly improved” since Stage 2 drought restrictions were enacted in early April.

“Our customers have responded very well to the call to use even less water, and we can finally be confident that enough water from the late-season snows has reached our reservoirs to bring them to reasonable levels,” said Greg Austin, president of the Denver Board of Water Commissioners.

“While the drought is not over, conditions have improved enough that customers may water a third day, if their lawns need it. We all still need to do our part to protect against the possibility of another dry winter, and we ask everyone to continue to use even less,” Austin said. Continue reading
