#Drought news: Improvement in the Southwest #US and Rockies

Click here to go to the US Drought Monitor website. Here’s an excerpt:


This U.S. Drought Monitor week saw improvements on the map across parts of the Southeast, Northeast, Northern Plains, the Rockies, and Desert Southwest. In the mountains of drought-stricken areas of Colorado and New Mexico, the cool-season is off to a positive start in portions of the central and southern Rockies where snow shower activity continued this week. In California, persistent dry conditions led to expansion of areas of drought in northern parts of the state where a dangerous and fast-moving wildfire broke out late last week in the Sierra Nevada foothills leading to destruction of the community of Paradise. The Camp Fire is now the most deadly and destructive fire in the state’s history and so far has resulted in the loss of 48 lives and destroyed 7,600 homes. In southern California, the Woolsey Fire broke out late last week and spread quickly across the Santa Monica Mountains because of dry vegetation and strong Santa Ana winds. The fire led to the evacuation of more than 100,000 residents in Los Angeles and Ventura counties and has been responsible for the destruction of >400 homes. In the Southeast, widespread rain shower activity helped alleviate areas of dryness in Alabama and Georgia while short-term precipitation deficits led to expansion of drought in portions of Florida…

High Plains

On this week’s map, improvements were made in North Dakota with the removal of two areas of Severe Drought (D2) in response to normal to above-normal precipitation during the past 30-to-60 days. In northeastern Kansas, areas of Abnormally Dry (D0) and Moderate Drought (D1) were reduced in response to improving soil moisture conditions and above-normal precipitation during the past 60-to-90 days. For the week, the region experienced below-normal temperatures with the largest negative anomalies (12-to-24 degrees below normal) observed in North Dakota, northeastern Nebraska, and northeastern Wyoming…


In California, several dangerous and destructive wildfires broke out in both southern and northern California during the past week. In Butte County in northern California, the Camp Fire devastated the Sierra Nevada foothill community of Paradise – destroying nearly the entire community including 7,600 homes. According to CAL FIRE, the fire has burned in excess of 130,000 acres (35% contained) and has been responsible so far for the loss of 48 lives – making it the deadliest wildfire in California history. North of Los Angeles, the Woolsey Fire has burned 97,000 acres (40% contained) in and around the Santa Monica Mountains leading to the evacuation of more than 150,000 residents and destruction of >435 homes. Continued dry conditions in California led to expansion of an areas of Moderate Drought (D1) in the Sacramento Valley, extending to the western foothills of the northern Sierra Nevada. In the Rockies, widespread snow showers were observed in the Front Range and adjacent foothills as well as in the Sangre de Cristo Range, leading to improvements on the map in north-central and south-central Colorado. Overall, Colorado’s snowpack is off to a positive start with above-normal snow water equivalent (SWE) levels in the Front Range, Sangre de Cristos, and the Mosquito Range of central Colorado. In New Mexico, recent snowfall and above-normal SWE levels led to reduction of Extreme Drought (D3) in the north-central part of the state. In eastern New Mexico, recent storm activity and improved soil moisture levels have improved conditions leading to reduction in areas of Moderate Drought (D1) and Severe Drought (D2). In central Arizona, wet conditions during the past 90-days led to reduction in areas of Moderate Drought (D1). In the Northern Rockies near Glacier National Park, areas of Abnormally Dry (D0) were removed in response to above-normal SWE levels associated with recent snowfall. Average temperatures were below-normal across most of the region during the past week…


On this week’s map, only minor improvements were made in the region including removal of remaining areas of Abnormally Dry (D0) in northeastern and southwestern Mississippi where heavy rains this week erased existing short-term precipitation deficits. In the Texas Panhandle, areas of Abnormally Dry (D0) and Moderate Drought (D1) were reduced in response to improving soil moisture levels from snow shower activity in and around Amarillo. During the past 120-days, precipitation across Texas has been well above normal. For the week, average temperatures were well below normal with the greatest negative anomalies (9-to-15 degrees) observed in the Texas Panhandle and northern Oklahoma…

Looking Ahead

The NWS WPC 7-Day Quantitative Precipitation Forecast (QPF) calls for light-to-moderate accumulations ranging from 1-to-3 inches (liquid) along the Eastern Tier with the heaviest accumulations forecasted for portions of the Southeast and southern Mid-Atlantic. In the central and southern Appalachians, a wintry mix of rain, freezing rain, and snow is expected. West of the Mississippi River, conditions are expected to be dry with the exception of light-to-moderate accumulations in the Northern Rockies and western Washington. The CPC 6–10-day outlook calls for a high probability of above-normal temperatures across portions of the West including Arizona, California, Nevada, Utah, Oregon, and western Washington. In contrast, there’s a high probability of below-normal temperatures in the Midwest, Mid-Atlantic, and Northeast. In terms of precipitation, there is a high probability of above-normal precipitation across California, the western Great Basin, and Arizona while the Pacific Northwest and Northern Rockies are expected to be drier than normal. Moving eastward, above-normal precipitation is expected across Texas, the Gulf Coast, Southern Plains, and Florida while below-normal precipitation is expected in the Midwest, Mid-Atlantic, and Northeast.
