For over two hours Wednesday afternoon, cities in the Texas panhandle were hammered by a hailstorm that left quarter-sized balls of ice stacked chest-high in some areas, Time NewsFeed reports.

The deluge began around 3:30 a.m. Over the next few hours, fast-moving hailstones pummeled the area north of Amarillo, Tex., which had lately been sitting in mud and dust due to a lack of precipitation, according to the news organization. The hail mixed with the mud and dust to create four-foot high mounds that shut down a major highway for the next 18 hours.

The National Service Office in Amarillo posted a striking picture on Facebook of a local fireman standing between the mounds and the floodwaters, accumulating due to melting ice and heavy rain.

Krissy Scotten, a meteorologist at the National Weather Service Office in Amarillo,told msnbc.com that the rain and floodwater cause the drifts, and chest-high mounds like the ones shown in the photo are uncommon.

“I can assure you we do not have big rocks like that in West Texas,” Scotten told msnbc.com. “Anytime you have hail accumulate 2 to 4 feet high and get over three inches of rain, no matter how it occurs, it’s pretty incredible.”

Brian Thomas, the sheriff for Potter County, concurred with Scotten, saying the hail mounds were erratic.

“This was just one of those weird storms that just sat here and came down extremely heavy in this one area,” Thomas told KAMR-TV.

Luckily no injuries have been reported from the storm, the station reported.
