Similar to the FAA OIS, TMU Notices allow facilities to communicate ground stops, delays, routing, etc. to other facilities. This is especially useful during events or busy periods. For VATUSA purposes, this will be also be called N.T.O.S.: National Traffic Operations Status.
Facility staff members have access to manage Notices for each sector that your facility has a TMU map for. Active notices can be found on the public-facing TMU Notices page, linked under TMU Maps.
On another note, all timestamps on the website are now in UTC for consistency.
