Extreme winds and possible storms expected on Tuesday have forced the cancellation of Mardi Gras parades in Jefferson Parish, La., as officials in neighboring New Orleans moved up parade starting times because of the forecast.

The National Weather Service is warning that strong winds, with gusts reaching up to 60 miles per hour, will begin early in the morning, creating potentially hazardous conditions for parade floats and spectators.

“I’m going to cut to the chase with very disappointing news,” the Jefferson Parish president, Cynthia Lee Sheng, said at a news conference on Monday. “Tomorrow’s weather, especially the gusty winds, is severe enough that we have no other choice other than to cancel our scheduled parades for tomorrow.”

There are two parades in Jefferson Parish on Mardi Gras. The Krewe of Argus was scheduled to roll with 20 floats through Metairie, La., followed by the Krewe of Elks Jeffersonians with 43 floats.

Collin Arnold, the director of New Orleans Homeland Security, told New Orleans’s Fox affiliate that strong winds could create a public safety hazard for the floats, riders and spectators in the early part of the day, with the potential for tornadoes and thunderstorms later in the afternoon.

The New Orleans Police Department said on social media that it was adjusting the starting times of its Zulu and Rex parades, with Zulu set to begin earlier at 7 a.m., and Rex starting around 9 a.m. Both would be slightly pared down, with “no additional elements,” officials said.
