The NHC was very explict about ***not*** issuing any land based tropical
warnings for Sandy north of Virginia/Chesapeake Sound as it approached
land. The off shore tropical warning products up to the Canadian Border
ended 5 miles off shore (but went out to 200 miles as the storm was
considered tropical until landfall). The near shore (0-5 miles) is where
the local WFO took over and issued their local office products.
More to that reasoning, the tropical storm was forecast to go extropical
immediately upon landfall as colder air from the phasing land trough and
jet stream was ingested. When that occurs, tropical products are no longer
considered technically accurate and watch/warning message issuance reverts
to the local WFO. Further to that point, the NHC stated they didn't want
to issue land tropical warning products only to see them rescinded when
the storm went extropical. They explictily stated that so as to avoid
confusing the public. Made perfect sense.
To which I saw considerable collaboration on what products were issued by
the various WFO's so as to limit confusion. I think that plan well handled
the total storm event.
To that end, I also believe EAS was appropriately not used. The storm was
well predicted and hazards widely disseminated days in adavance. EAS is
for the short fuse "Do it now!!!" message which doesn't have a lead time
to otherwise disseminate through news channels.
