The Red Bull Flugtag event scheduled for this morning at North Avenue Beach has been canceled because of "unsafe marine conditions," event organizers said.

The event, which lets teams compete with creatively designed aircraft taking off from a 30-foot-high flight deck and landing in Lake Michigan, was scheduled to begin at 11 a.m. with the first flight at 1 p.m.

According to event spokeswoman Jennifer Belongia-Barak, concern about high waves, perhaps as high as 4-7 feet, led to the cancellation. She said that 28 teams had entered the event, which will not be rescheduled.

All events at the beach are canceled, she said, but a planned after-party at Zella, 1983 N. Clybourn Ave.,  is still on. It runs from 4:30 p.m. to 9 p.m.; tickets are $35.

In the past, the promotion had drawn tens of thousands of spectators, according to past Chicago Tribune stories.
