At 8 a.m. EDT (1200 UTC), the eye of Hurricane Irma was located near latitude 21.8 North, longitude 74.7 West. There is an airspace flow program for traffic going into Florida today that started at 13z and runs until at least 2259z. There are also numerous required reroutes to help manage the significant volume of traffic into and out of Florida and the northeast. ZMA is requesting that to the extent possible, operators file out of ZMA via the Q-routes on the west side and the ARs or AZEZU routes on the east side. These will be the best routes out of Florida and likely to receive the least delays throughout the day. Airports throughout Florida are likely to begin closing on Saturday.
