Just a small portion of Colorado is abnormally dry according the latest U.S. drought monitor.
Much of Colorado鈥檚 current moisture is a holdover from the record wet spring according to Mark Svoboda a climatologist and the Monitoring Program Area Leader for the National Drought Mitigation Center. The information is based on satellite images and ground observations especially in remote areas of Colorado, like Grand County, the largest yellow spot on the map.
鈥淎 lot of these areas where we鈥檝e seen a lot of issues this year are in the forested mountainous areas. A lot of fire issues in Washington, Oregon and California. It鈥檚 not unusual,鈥� he said.
Colorado continues to be , where much of the Pacific Northwest and especially California are in the worst drought seen in decades.
鈥淲e haven鈥檛 seen a drought like this in California in 40 years. We鈥檙e living in a drought that would rival any in the last century plus another decade. Historically, you don鈥檛 see these kinds of droughts come around and then last for several years. That鈥檚 what makes it unique it鈥檚 not only the intensity, but also the duration,鈥� Svoboda said.null
Unlike other natural disasters, droughts can last for years causing billions of dollars in economic, social and environmental damage.
Why El Ni帽o Won鈥檛 Fix the Drought
Warmer oceanic sea surface temperatures, which characterize the natural phenomenon of , will release more moisture into the atmosphere, which rises into the jet stream and 鈥渋s our conveyer belt of storm tracks and activity,鈥� he said.
Forecasters expect a warmer winter in the central to northern Rockies and up into the Pacific Northwest, 鈥渟o the drought could actually intensify up in the Pacific Northwest,鈥� Svobota said.
remains the wild card.
鈥淪outhern California certainly with the strong El Ni帽o the odds are tilted in favor of being wetter, but that doesn鈥檛 mean that will push all the way up to the Sierra Nevada where we need big snows to fill in the reservoirs and streams.鈥�
Because of the duration and severity of the drought, Svobota thinks it will take years of at least average snowpacks to bring the state back to a comfortable water storage position.
鈥淸It all depends on] where that [El Ni帽o] pattern sets up. Where does it come on shore in California? And that remains to be seen.鈥�
Climatologists have forecast that the El Ni帽o may stick around through spring of 2016. But the key is what form the moisture takes.
鈥淭he perception is going to be El Ni帽o is here, the drought is over,鈥� Svobota said. 鈥淚t takes more than that to recover. We want to see it in the form of snow, not rain. We want big snows that melt out slowly next summer that will help them sustain and start the recovery process. This winter is going to be really really critical.鈥�
