ECFP Background

The Extended Convective Forecast Product (ECFP) Planning Tool is a graphical representation of the forecast probability of thunderstorms. The product identifies graphically where in the US thunderstorms are likely over the next 72 hours. It is intended to enhance the TFM Collaborative Forecast (TCF). The TCF is only valid out to 8 hours. The product is not a TCF forecast (it is not forecasting the exact TCF criteria), but intended to support the long range planning for TCF type of constraints in the National Airspace System.

The ECFP planning tool has been developed in response to FAA and Industry needs in planning for weather hazards, specifically convection, one to two days in advance. To meet these planning needs, and to support TCF planning beyond 8 hours, the ECFP is intended to provide traffic planners and collaborators a quick-look forecast of the greatest probability of convection/thunderstorms.

The ECFP is intended for FAA Traffic Managers at Air Route Traffic Control Centers (ARTCC), FAA Air Traffic Control System Command Center (ATCSCC), airline and aviation industry dispatch and flight planners, and private weather vendors supporting airline/FAA.

New 3 Hour ECFP

This new ECFP depiction is an automated graphical forecast created from the Short Range Ensemble Forecast (SREF) Calibrated Thunderstorm guidance with forecast times valid in 3 hour intervals. Probability of Thunderstorm contours are depicted at 30, 50, and 70% probabilities. Blue hashed areas represent 30-49% probability, solid orange-lined areas represent 50-69% probability, and solid magenta-filled areas represent greater than 70% probability.

Archive ECFP

The archive ECFP information will retain the legacy ECFP graphics. This product is also an automated graphical forecast created from the (SREF) Calibrated Thunderstorm guidance. Probability of Thunderstorm contours are depicted at 40, 60, and 80% probabilities, using TCF-like shading. Hashed areas represent 40-59% probability, solid lined areas represent 60-79% probability, and solid blue filled areas represent greater than 80% probability.
