The anamoly was not a horde of critters, but detritus from a nearby military base, according to the National Weather Service.
“There are news stories going around about a swarm of grasshoppers potentially appearing on our northern UT weather radar,” the NWS said in a tweet on Saturday. “After further investigation, we’ve determined that the most likely cause of the signature on 6/21 was chaff originating from Nellis Air Force Base in Nevada.”
Chaff is a reflective substance dropped by military aircraft that scrambles radar systems.
Meteorologists initially thought the cloud might be insects because it appeared non-uniform, versus the more contiguous shapes of major weather patterns.
“It can sometimes confuse our radars as well,” Utah meteorologist Monica Traphagan told the Salt Lake Tribune. “The appearance of insects and chaff can have some similar characteristics, which led to the error in the original analysis.”
Utah residents could be forgiven for thinking a biblical bug cloud was heading their way.
In nearby Nevada, blood-red Mormon crickets have been swarming in the north of the state in a mass hatching that began in May.
“It’s almost like a biblical plague,” Elko resident Dana Dolan told The Associated Press
In 2021, large swarms of grasshoppers hit across Utah during a drough, damaging agricultural yields.
The state only recently exited the extreme drought stage it has been in since June of 2020.
A massive snowpack in the winter of 2022 helped get the state back on track.
“Just looking at the entire state at once, we’re currently about 195% of normal,” Utah Snow Survey Supervisor Jordan Clayton told 2News in March. “That number is starting to become less meaningful because what’s probably more interesting to viewers and to listeners is that we’re well outside of the 1983 record at this point,” Clayton said. He went on to call Utah’s ‘22-’23 winter snowpack “the greatest since 1952.”
