(CNN) A wet spring in Las Vegas has spawned hordes of grasshoppers so large, they're showing up on the weather radar.

In viewing the radar, CNN meteorologist Allison Chinchar said it looked like there were two storms over the Vegas area: one north of the city (that was actual rain) and another right over Las Vegas. But the second one wasn't moving as rain normally would, she said.

"It looked as though it should be torrentially downpouring in Las Vegas," said Chinchar.

By changing the settings on the radar, meteorologists could see that the other "storm" was actually the massive hordes of grasshoppers that have settled over the city in recent days, Chinchar said.

The National Weather Service office in Las Vegas said in a tweet Saturday that people have been asking about "the widespread radar returns" in the city over the past few nights.

🤓 Some of you have been asking about the widespread radar returns the past few nights in #Vegas. Radar analysis suggests most of these echoes are biological targets. This typically includes birds, bats, and bugs, and most likely in our case--> Grasshoppers. 🦗 #VegasWeather pic.twitter.com/reQX7hJR7Y — NWS Las Vegas (@NWSVegas) July 27, 2019
