As promised in my final 2012 hurricane season birdseye discussion back in December...I still plan to release post-storm reports for the 2012 Atlantic Hurricane Season which will include an evaluation of how my storm forecasts (issued on these birdseye discussions) compared with that of the official forecasts from the National Hurricane Center.
