Parades planned for Fat Monday, or Lundi Gras (LUHN-dee grah), are threatened by more rain in the forecast.
That includes the Krewe of Orpheus, the star-studded group led by entertainer Harry Connick Jr. It was scheduled to roll at 6 p.m. Monday, with Connick, actor Gary Sinise and New Orleans musician Troy "Trombone Shorty" Andrews.
And Fat Tuesday could be a wet one: The National Weather Service expects rain for much of the day, when as many as 1 million people party in the streets.
Carnival season culminates Tuesday with the Rex and Zulu parades. So far, they haven't been canceled.
