The Coca-Cola 600 started under blue skies and bright sunshine at Charlotte Motor Speedway. Off to the east a line of showers and storms began to form.
This activity is associated with tropical storm Beryl that is preparing to make landfall later tonight in north Florida and southeast Georgia. That is why the storms are coming from the east moving west.
At 7 p.m. ET these storms were 35 to 40 miles to the east-southeast and moving west-northwest at an estimated 15 to 20 miles per hour. This roughly puts the storms arrival at 9:30 p.m. ET if they don't weaken.
