FRISCO — Even though winters may become warmer as climate change ramps up, it probably won’t result in a big reduction of winter deaths, says a new study that contradicts the conventional wisdom on health impacts of climate change.

“For years I’ve been hearing people say that global warming will reduce winter deaths but I wanted to check this claim out for myself,” said Columbia University Professor Patrick Kinney.

Kinney and his colleagues used statistical methods to pick apart the possible factors contributing to deaths of older people during the winter; they found that cities with warmer winters have similar amounts of winter deaths as do cities with colder winters. The new research was published this week in IOP Publishing’s Environmental Research Letters journal. Continue reading

Flows in Blue River tributaries like Straight Creek are near their seasonal peak.

*Story corrected at 2 p.m. Dillon Reservoir outflow to the Blue River increased to 1,600 cfs Monday, July 15.

Staff Report

FRISCO — Dillon Reservoir should be full within a week, according to the latest update from Denver Water, which just bumped up the outflow to the Lower Blue to make room for more runoff the next few days.

As of June 15, Denver Water was releasing about 1.600 cubic feet per second from Dillon Reservoir, with about 2,200 cfs flowing in from the Blue River and its tributaries. And Denver Water is expecting more high inflows for the foreseeable future, according to a recent email update:

“A fresh look at the estimated level of snowpack above Dillon Reservoir … tells us there is still eight inches of snow in some places, meaning high flows can be expected for the foreseeable future. The good news is that inflows to Dillon Reservoir – which have ranged from 2,206 to 2,623 over the past several days – appear to be trending downward.” Continue reading

May precipitation breaks records in southern Colorado

Wet spring boosts streamflow forecasts

Miracle May?

Staff ReportFRISCO — Statewide precipitation was more than twice the average, federal water watchers said in their June update. The rain and snow, along with cool temperatures at higher elevations, delayed the onset of runoff and boosted streamflow forecasts for the summer. “This substantial addition of moisture, both in the form of snow and rain have notably increased water supply forecasts across the state from a month ago,” said Brian Domonkos, the Colorado snow survey supervisor for the USDA Natural Resources Conservation Service.

Flooding is possible in southwest Colorado, parts of the high country, as well as many Front Range streams.

Staff Report

FRISCO — With more subtropical moisture streaming into Colorado from the Southwest, parts of the state are under flood watches and flood warnings at the start of the weekend, including:

Blue River snowpack still growing.

Staff Report

FRISCO — Late-season storms have helped boost snowpack in the Blue River to near last year’s level, promising healthy runoff and flows in Summit County, according to Denver Water.

The effects of the steady barrage of spring storms is already showing up the Lower Blue River, where flows are increasing due to increased releases from Dillon Reservoir, according to Denver Water, which won’t be diverting water through the Roberts Tunnel until mid-July at the earliest.

Staff Report

FRISCO — A new study led by Colorado-based scientists seems to reinforce the old saying that, when it comes to the state’s weather, there’s no such thing as normal.

The research aimed to track seasonal and geographical patterns of extreme weather events, especially the monster storms that create headaches for emergency responders and resources managers. But pinpointing those trends is not easy the weather experts found. Continue reading
