9.  Weather Reconnaissance Area (WRA) 

a.  General.

 Hurricane Hunters from the United States Air Force Reserve 53

rd

 Weather Reconnaissance 

Squadron (WRS) and the National Oceanic and Atmospheric Administration (NOAA) Aircraft Operations 

Center (AOC) operate weather reconnaissance/research aircraft missions, in support of the National Hurricane 

Operations Plan (NHOP), to gather meteorological data on hurricanes and tropical cyclones. 53

rd

 WRS and 

NOAA AOC aircraft normally conduct these missions in airspace identified in a published WRA Notice to Air 

Missions (NOTAM). 

b.  WRAs.

 Airspace with defined dimensions and published by a NOTAM, which is established to support 

weather reconnaissance/research flights. ATC services are not provided within WRAs. Only participating 

weather reconnaissance/research aircraft from the 53

rd

 WRS and NOAA AOC are permitted to operate within 

a WRA. A WRA may only be established in airspace within U. S. Flight Information Regions (FIR) outside of 

U. S. territorial airspace. 

c. 

A published WRA NOTAM describes the airspace dimensions of the WRA and the expected activities 

within the WRA. WRAs may border adjacent foreign FIRs, but are wholly contained within U.S. FIRs. As ATC 

services are not provided within a WRA, non

−

participating aircraft should avoid WRAs, and IFR aircraft should 

expect to be rerouted to avoid WRAs.
