SAFETY

Stay Ahead of the Weather
AWWs are provided for ground decisions and are designed to ensure the
safety of passengers, airport personnel and others who may be endangered
by weather events.

N

ational Weather Service (NWS) local
Weather Forecast Offices (WFOs) provide
routine aviation weather products which
are designed specifically for aircraft flight
operations - takeoffs, landings and inflight conditions near the airport.
WFOs can also provide Airport Weather Warnings (AWWs) for "weather phenomena, which
can adversely impact airport ground operations."
AWWs are provided for "ground decisions" not
"in-flight operations."
To accommodate the variety of terminal circumstances, an AWW is issued based on weather criteria
specific to each airport. These criteria have been
predetermined by mutual agreement between the
WFO and the local airport management and are
formalized by a Letter of Agreement (LOA). According to National Weather Service Instruction 10-108,
published in 2019, the AWW will "include the triggering phenomenon, location, start time (end time
as needed) and may include additional remarks."
AWWs are designed to ensure the safety of passengers, airport personnel and others who may be
endangered by weather events. Their issuance also
necessitates changes in operations or procedures
on the ground. Refueling of aircraft can be halted

by a lightning threat. Snow and/or ice will lead
to deicing procedures on aircraft. Snow removal
may be necessary to complete standard operations.
Aircraft and supporting equipment may need to
be tied down during high wind events.
The LOA is basically the contract between the
WFO and the airport. It establishes the weather
elements to be warned for, dissemination mechanisms and points of contact. This LOA may be
amended at any time by mutual consent of all
parties. It is either specifically stated, or at least
implied, that the described weather event may
affect not only the immediate airport ground
operations but the surrounding area within 5
statute miles of the airport center. The AWW was
designed to complement the standard NWS forecasts and warnings. Airport management should
continue to refer to these products.
AWWs are issued with as much lead time as
possible. This does vary depending on the weather
element being dealt with. The actual lead time
by element will be determined in advance by
agreement of the WFO and airport and this will
be reflected in the LOA. Thunderstorm-related
warnings typically have a short lead time, hours
or even minutes. Major winter storms or tropical
