Tropical Cyclone HENRI - AL082015

This page compares PIIH predictions for storm HENRI - AL082015 with models currently used by the National Hurricane Center. To compare model accuracy we use Mean Average Deviation (MAD; average absolute prediction error) and Mean Squared Error (MSE; mean squared prediction error). We report the errors here as averages over the whole storm, averages per forecast period (12 to 120 hours into the future), and by individual prediction.
