Overview

At 5 a.m. EDT (0900 UTC) the National Hurricane Center (NHC) issued its final advisory on Irma, which has lost its tropical characteristics and is now classified as a post-tropical cyclone. The center of Irma was located near latitude 33.0 north and longitude 85.2 west. Irma has been moving northwestward through the southeast U.S., and will continue this motion and approach the Tennessee Valley by Tuesday afternoon. Irma is expected to weaken throughout the day on Tuesday.

Minimum central pressure is 998 mb (29.47 inches).

Track Information

What's left of Irma will continue to slowly drift northwest before turning back to the east/northeast. At this point, there are just showers and isolated storms that are no longer causing significant impacts to traffic management.

Airport Information

Operators planning to travel to areas impacted by Irma – Jacksonville, Miami and San Juan centers, as well as the Piarco FIR – should check NOTAMs and call service providers before each leg.

More airports are opening, especially the larger ones, but there are still issues with staffing, ground access to airports, damage to facilities (ILS, radar, etc.), availability of customs, availability of fuel, etc. The most important thing this week will be to understand the limitations of the system after the devastating impact of hurricane Irma.

The FAA Command Center has been posting a list of key equipment outages and failures due to hurricane Irma on their Advisory Database page twice a day. As with everything else, additional information can be found in NOTAMs.

Route Information

There are some routes out to help with increased traffic into the Florida area due to issues with frequency coverage on the east coast of Florida in addition to some of the other challenges noted above.

Both the Ohio Valley and Midwest to Florida have been issued to help manage the traffic. They are also monitoring the JX7 as a way to watch the amount of volume returning to Jacksonville (ZJX), Miami (ZMA) and San Juan (ZSU) centers as well as Piarco FIR. An airspace flow program is not out of the question through the end of this week to help manage traffic volume into the south.

Airspace coordination areas (ACAs) have been issued via NOTAM. At this time, there are no Irma-related temporary flight restrictions (TFRs). The ACAs urge pilots to "exercise extreme caution due to the presence of numerous flight operations engaged in disaster response and recovery efforts."

Operators are encouraged to monitor the FAA Current Reroutes page and the FAA Advisories Database for the latest on required reroutes and route closures.
