SUBJECT:  Soliciting Comments by October 28, 2016 on the

          Experimental Collaborative Aviation Weather

          Statement (CAWS)


Effective 1000 UTC March 1, 2016, the NWS Aviation Weather

Center (AWC) in Kansas City, MO, will resume the experimental

Collaborative Aviation Weather Statement (CAWS). NWS

meteorologists collaborate with airline meteorologists, and

other airline and Federal Aviation Administration (FAA)

personnel to produce the CAWS product. The CAWS focuses on

specific, convective impacts to the core 29 airports and high

traffic en-route corridors. The product is event-driven,

supporting the ability of the FAA to more effectively initiate,

adjust or terminate planned or active Traffic Management

Initiatives (TMI) and balance traffic demand.


The CAWS product is a step towards the FAA's

collaborative Operational Bridging (OB) process. The OB concept

is a set of weather forecasting processes, communication tools

and engagement protocols between meteorologists and Air Traffic

Management (ATM) decision makers. The intent is to accelerate

the transition of aviation weather forecasts to be more event-

driven, enabling more timely ATM decisions based on improved

precision (e.g., location, duration, magnitude of weather) and

National Airspace System predictability.


NWSChat (password protected) will be leveraged as a web-based

platform for continuous CAWS collaboration. Only authorized

users may take part in the CAWS chat. The AWC meteorologists,

National Aviation Meteorologists, Center Weather Service Unit

meteorologists, ATM decision makers, and others will collaborate

on CAWS before issuing it.


The Experimental CAWS will be available from:

1) AWC website:

2) NWS Telecommunications Gateway:
