A rainy Sunday pushed six regional Mardi Gras parades later in the schedule. Here are times and maps for Femme Fatale, Carrollton, King Arthur, Barkus, Atlas and Dionysus.

Due to the high possibility of rain, parades previously expected to roll Sunday on the Uptown New Orleans route have been rescheduled. The krewes of Femme Fatale, Carrollton and King Arthur will now take place on Tuesday night starting at 5:30 p.

Be on the lookout this Mardi Gras for a little extra star power in New Orleans as Shaquille O'Neal, "True Blood" star Rutina Wesley and others reign as celebrity monarchs in parades. Why it matters: Some will throw custom doubloons and swag.
