The National Weather Service is the official issuer of a watch or a warning, based on expected weather conditions.

Stormcenter7 Meteorologist Brett Collar explains the difference.

In severe weather season, knowing the difference between a watch and a warning can be life-saving.

WATCH means you should prepare for the possibility of a severe storm or tornado.

WARNING means you should take action now, get to a safe location because severe weather is occurring or a tornado has been seen or indicated by radar.

Doug Cope, the leader of Ohio Task Force One, called NewsCenter 7 to describe what was going on inside the arena.

“At about 8:10 they made an announcement for all the students on the floor to egress back to the backstage area, and this was because of the large monitor that hangs over the floor for basketball games,” Cope said. “They were telling folks to stay off the concourse area because of all the glass doors.”

Right then, NewsCenter 7’s James Brown gave a dire warning.

“Please tell the folks not to go outside, it’s headed right toward you,” Brown said.
