Weather, of course, is a major factor in staging the Parade. The Committee is well aware of its responsibilities to participants and spectators alike. When weather conditions threaten, the Committee will use sound judgement, based on up-to-date weather information, in deciding whether to stage or postpone the Parade.

If postponed because of inclement weather, the Parade automatically is rescheduled for the Sunday following March 17 for all units indicating on their application that they will be available on that day to take part. Please answer the application form question about availability of your unit(s) to be in a rescheduled Parade. All broadcast media will be notified to announce any postponement, and band directors will be called individually.

If weather is in doubt, please do not try to call the Committee. Instead, please listen to the broadcast media for the announcement.
