Drought pressures will increase in California and western areas of the United States this spring even as the dry season begins, the government's Climate Prediction Center said Thursday.
"Periods of record warmth in the West and not enough precipitation during the rainy season cut short drought relief in California this winter, and prospects for above-average temperatures this spring may make the situation worse,'' Jon Gottschalck, chief of the Operational Prediction Branch at the Climate Prediction Center, said in issuing its spring outlook.
The center, a division of the National Oceanic and Atmospheric Administration, also said rivers in western New York and eastern New England have the greatest risk of spring flooding in part because of heavy snowpack coupled with possible spring rain.
The western United States is expected to see the multi-year drought continue and intensify in 2015 and extend into the northern Plains, the outlook said. Drought is forecast to persist in California, Nevada and Oregon through June, with the onset of the dry season in April.
"I see nothing that would indicate much improvement, if any improvement, in the overall situation for field crops for 2015,'' said Brad Rippey, meteorologist with the U.S. Department of Agriculture, noting he expected to see a significant drop in field crops again this year in California.
"Drought is also forecast to develop in remaining areas of Oregon and western Washington. Drought is also likely to continue in parts of the southern Plains,'' NOAA said.
Drought also is likely in the northern Plains, upper Mississippi Valley and western Great Lakes, but forecasters expect drought improvement in some areas of the Southwest, southern Rockies and Gulf Coast.
Above-average temperatures are favored this spring across the Far West, northern Rockies, and northern Plains eastward to include parts of the western Great Lakes, and for all of Alaska. Below-normal temperatures are most likely this spring for Texas and nearby areas of New Mexico, Colorado, Kansas and Oklahoma, the outlook said.
In the Midwest crop belt, a lack of snowfall in the northern states will mean an early planting season and little to no flooding, Rippey said. In contrast, the southern crop belt is wet and has already seen minor to moderate flooding.
"I would expect planting to go a little better in the upper Midwest this spring than it will in the Ohio Valley,'' Rippey said.
