US south ‘still under the gun’ after deadly storms.

South/America: A storm system that blasted the U.S. South was weakening on Tuesday but another was on its way after thunderstorms and tornadoes left a swath of destruction, killed at least two people and tore up a NASCAR grandstand. More than 30 tornadoes struck on Monday and Tuesday from Texas, Oklahoma and across the southern plains into Missouri, said meteorologists with the National Weather Service.

While this weakening storm system is expected to roll into the Great Lakes region early Wednesday, another system is brewing Wednesday night into Thursday, said Brian Hurley, a forecaster with the NWS Weather Prediction Center. “The Southern Plains can`t catch a break,” Hurley said. “More storms will develop overnight into Thursday morning.”

Rainfalls are predicted to be about 2 inches across eastern Kansas, Oklahoma, and into western Missouri, with localized spots getting up to 5 inches, he said. “That whole area is still under the gun,” Hurley said.

In Wheatland, Missouri, at the Lucas Oil Speedway, a reported tornado injured 7 people, flipped over cars, toppled campers and damaged the grandstands, with local media images showing piles of twisted metal and upside down vehicles.

The Memorial Day weekend “Lucas Oil Show-Me 100” races at the speedway, about 120 miles southeast of Kansas City, were canceled indefinitely. A crowd topping 3,000 fans of the National Association for Stock Car Auto Racing (NASCAR) had been expected, track officials said on Tuesday.

Dozens of people were rescued from rising floodwaters and felled trees that smashed homes and blocked roadways in Oklahoma on Tuesday. Crews using boats pulled at least 50 people from rising water as heavy downpours inundated roads and homes, Oklahoma Emergency Management Agency spokeswoman Keli Cain said.
