1. CCFP and CAWS WET Date: Fall 2014

2. Overview Evolution of CCFP Collaborative Aviation Weather Statement Timeline of Implementation Summary

3. The Concept of CCFP is Evolving Focus weather forecast collaboration resources on weather with the highest potential of impact to air traffic Take advantage of a blend of the newest high- resolution computerized weather forecast models Issue critical weather forecast information at the optimal time (event driven), even if it is between the usual 2-hour update cycle

4. The Concept of CCFP is Evolving CCFP will become Automated CCFP on 1 Nov 2014 – CCFP “look and feel,” forecast issuance frequency, and full-CONUS coverage will be remain unchanged – Schedule will improve to 24-7-365 issuance New product: Collaborative Aviation Weather Statement (CAWS) coming March 2015 – National Weather Service and Industry meteorologists will collaborate on CAWS 24/7 unlike limited CCFP collaboration in the past – Event-driven – timed and focused on areas of potential air traffic impact (enroute and/or terminal) – More precise forecast and flexible format than 2-hourly CCFP

5. Old CCFP vs New (automated) CCFP

6. CCFP (Old and Automated) CCFP (Current) – Human generated polygons – Issued 1 Mar – 31 Oct – 4, 6, 8 hour forecast – Issued every 2 hours (03- 22Z) at top of hour just prior to SPT – CCFP criteria well known CCFP (Automated) – Uses a blend of state of the art computer models to draw polygons – Issued year round – 2, 4, 6, 8 hour forecast (web) – Issued every 2 hours at bottom of hour prior to SPT – Uses current CCFP criteria and color scheme – No changes to format, headers, etc.

7. CCFP (Automated) Example

8. CCFP: Where to find it? CCFP (Automated) – Will replace current CCFP on TFMS and web on 1 November 2014 – Will show 4, 6, 8 hour forecast on TFMS – Also available on AWC Website: http://aviationweather.gov/ccfp http://aviationweather.gov/ccfp – Will show 2, 4, 6, 8 hour forecast on website – Also will be available though NWS usual gateways – Available 24/7 including winter months (Nov-Feb)

9. Coming March 2015: CAWS Collaborative Aviation Weather Statement (CAWS) Event driven advisory for US CONUS airspace Contains both a text discussion and graphical picture of impacted region Initially issued for convective events but other restrictions (icing, fog, turbulence) will be added in the future Training and familiarization early 2015

10. CAWS Summary Event driven, high resolution text and graphical forecast Focused on convective events which pose high impact to air traffic flow (enroute and terminal) Collaboration: government & industry meteorologists Disseminated to TFM planners and CDM stakeholders concerning convective weather constraints deemed critical to traffic flow management Other weather constraints will be added in the future CAWS archive is available on AWC website 10

11. Important Dates 31 Oct 2014: CCFP shuts down for season 1 Nov 2014: Automated Convective Forecast Product replaces current CCFP Feb 2015: CAWS Training Package available 1 March 2015: Routine CAWS issuance begins
