Shortly after 8 p.m. Central Time, fans at the semifinal match between Colombia and Chile were told to leave their seats and take shelter in the lower level concourse at the stadium due to severe lightning and thunder.

Severe storms soaked the downtown Loop with torrential rain by the mid-evening hours, WBBM-CBS2 Meteorologist Ed Curran reported.

By 9:35 p.m. local time Wednesday, the rain had stopped in downtown Chicago, and just before 10 p.m. Chicago time, officials announced that the game would resume, WBBM-CBS2’s Sandra Torres reported. But some people left Soldier Field well before that.

Photos at the scene showed flooded concourses as some people left the stadium. A video clip tweeted by Mario Andres Luna showed water cascading down a stairway at Soldier Field like a waterfall.

Chicago’s Navy Pier was also closed due to the storm.

The storms were poised to head eastward, though the bulk of the system will likely strike south of New York City. CBS2’s Lonnie Quinn forecast that the New York City, Long Island and northern New Jersey are only under a marginal – or 10 to 20 percent – threat of severe weather while southern New Jersey was under a 20 to 30 percent, or slight, risk.
