Forecasters from services such as AccuWeather have taken issue with the National Hurricane Center's decision to not issue hurricane warnings north of North Carolina in preparation for Hurricane Sandy's arrival. They contend that citizens and governments might have taken even greater precautions had the NHC reinforced that a serious hurricane was approaching the mid-Atlantic. The NHC chose not to issue warnings further up the coast because Sandy technically would no longer be a hurricane once it began to mix with non-tropical air.
