Severe weather put the brakes on some of the world's fastest motorsports athletes over the weekend but NASCAR finally made its debut Sunday in Chicago after an overnight rain delay.
The NASCAR Cup started late in the day Sunday following torrential rains that delayed its Saturday start. The delay continued through the afternoon, and the event was shortened with darkness looming.
On Sunday night, New Zealand's Shane van Gisbergen, an Australian Supercar champion, became the first driver in more than half a century to win a debut NASCAR start.
“This was so cool,” he said after the race. “This is what you dream of. Hopefully I can come and do more.”
Chicago wasn't alone. Severe weather took aim across a wide swath of the U.S. from New York and Pennsylvania down to Arkansas.
Scattered showers were reported in Kentucky and Tennessee, and the line of storms was expected to shift into the Appalachians overnight.
In St. Louis, Missouri, a 33-year-old woman was killed when a tree fell on her car during severe weather, according to the Metropolitan Police Department.
Flooding was reported in Clinton County, New York.

“I am closely monitoring the situation and have directed my team to assist local officials however necessary," Hochul said in a statement Sunday.
