It is a long read. So much went right, not a lot went wrong but a lot of recommendations for future clarity. Probably the longest Service Assessment ever as it affected the entire NWS Eastern Region practically (over 90 million people).

A lot of the NHC questions have to do with the extratropical transition and inland impacts. Some thoughts:
* Tropical storm or hurricane watches/warnings should continue to be issued inland, but for ALL CWA's, not just coastal or near-coastal regions. In the case of Irene, that would have affected the Burlington, Buffalo, State College and Raleigh CWAs. That would eliminate the mixed messages.
* Once a storm becomes post-tropical, warnings should be retained as long as would otherwise be necessary (i.e. until the threat departs or if winds drop below tropical storm force).
* Coastal breakpoints should be just that - for over water. While most often, forecasts match or come close, the WFOs should be allowed to override and issue a lower (or higher) warning as necessary.
* Backup offices are difficult in this case since virtually ALL offices in NWS Eastern Region were affected by Irene. In a case like this, a special one-time agreement should be made for a special backup office outside the affected region (most likely a Central Region or Southern Region office).
