Seven Southwest US states suffering "exceptional" drought conditions

The changing of the seasons from winter to spring has brought an unwelcome worsening of drought across the U.S. Southwest and Southern Plains. The animation below shows drought conditions becoming more intense and widespread between the start of the animation on January 9 and the final frame on April 17.

At the start of the year, only a few small areas of extreme drought existed in the contiguous United States, the largest of them in Oklahoma and South Dakota. As the season advanced, extreme drought conditions expanded from Oklahoma into Texas and Kansas, with detached pockets also appearing in Arizona and New Mexico by mid-February.

By mid-March, drought in the panhandle of Oklahoma had reached "exceptional" status, and severe drought had pushed northward from Arizona and New Mexico into Utah and Colorado. As of mid-April, parts of seven Southwest states had progressed into exceptional drought.

Drought impacts are piling up. Endangered fish in the Rio Grande had to be rescued and relocated to wetter stretches as parts of the river in New Mexico dried up. In Arizona and New Mexico, birds and elk have been observed coming to stock ponds and yards for water and food as natural sources of surface water and vegetation become scarce.

In Colorado, livestock operators are hauling water for cows and sheep as stock ponds and streams dry up, and farmers along the Middle Rio Grande in New Mexico have been told to expect half their normal irrigation allotment. Fire danger is extremely high for so early in the season, and burn bans are in place across many counties and forest service districts in multiple states.

Comment: After one of the harshest winters on record, the US is now seeing drought and fire risks much earlier in the season than is usual.

With the sun dipping to its lowest activity in hundreds of years, erratic weather patterns are to be expected; the jet streams are meandering and the Atlantic Ocean circulation is the weakest in over 1000 years, and these are all clues that we are entering an ice age:
