Florence Update from NBAA Air Traffic Services

Updated Sept. 12, 2018, 1200 EDT

Major Hurricane FLORENCE is still a Category 4 storm with sustained winds of 115 knots. As noted previously, the "cone of uncertainty" shows the possible path of the center of the storm. Overnight, that cone shifted just a little more to the south. However, the important thing to remember is that the hurricane force winds in excess of 64 knots are reaching 75 miles from the center while the tropical storm force winds of 34 - 63 knots extend as much as 175 miles from the center.

As this monster gets closer to shore we'll start to hear from facilities regarding planned evacuations. Operators should prepare for the possibility that some towers will be evacuated (ATC Zero) if sustained winds are forecast to exceed 60 knots. Currently, the National Hurricane Center (NHC) forecast indicates that the most likely time to expect tropical storm force winds at the shore is later in the day on Thursday.

We have also been alerted to the issuance of the Airspace Coordination Area (ACA) NOTAMs. These are informational in nature and encourage pilots to "exercise extreme caution while operating in these areas due to ongoing current rescue operations." These will lay out the areas where the government is expecting to be carrying out rescue and recovery operations. There are NO RESTRICTIONS associated with the ACAs and at this time we are not expecting TFRs to be issued for this storm


NBAA Airspace/Airport Alerts are informational in nature. Official current NOTAMs are available from Flight Service Stations at 1-800-WX-BRIEF. Notices, restrictions, and advisories may change at any time and without notice. Do not attempt any operation in the National Airspace System without first obtaining and understanding a thorough pre-flight briefing. In addition to talking to a FSS Specialist, operators can use the FAA NAIMES website to check for the latest TFRs.
