Showers could complicate Wallenda's tightwire walk

Forecasters are calling for a chance of showers or thunderstorms to pass Wednesday afternoon, potentially making Nik Wallenda's planned tightwire walk over the Inner Harbor a little more slippery.

National Weather Service meteorologists are calling for a 50 percent of showers Thursday, with a particular risk after 3 p.m. The hourly forecast calls for passing thunderstorms around 6 p.m.

AccuWeather, meanwhile, has a risk of thunderstorms during the 5 o'clock hour of its forecast.

Wallenda is planning to walk a 1-inch-thick wire stretched from the second floor of the Light Street Pavilion to 90 feet above a barge on the harbor. The walk is scheduled for 5:15 p.m. and expected to take 15 minutes.

The walk is spotlighting the Ripley's Believe it or Not Odditorium scheduled to open June 1. Tim O'Brien, a spokesman for Ripley's said Wallenda would perform the walk in light rain conditions, but heavy rain and winds -- and, of course, lightning -- would be unsafe.

Wallenda is following in the footsteps of his great-grandfather, Karl Wallenda, who walked over the Inner Harbor to open the fourth annual Baltimore City Fair in 1973.
