Narrative:

An air carrier requested a weather deviation 30 [degrees] right of course; I probed deviation request into atop and numerous traffic conflictions were depicted. I then examined alternate clearances; climb or descent for deviation; deviation to the other side of course. Due to traffic volume on adjacent airways and traffic on the same airway; there were no deviation options available for the air carrier. I advised the air carrier unable deviation request due to traffic. The aircraft advised 'we are going to descend 300 ft; flight is declaring an emergency'. Upon receipt of pilot's intentions; I emergency altituded the flight at FL367 and requested a phone patch with the aircraft. On phone patch I advised pilot of traffic in the area and asked what direction and how far he was deviating. Pilot advised deviating 30 right of course at FL367. I advised pilot that I understood he declared an emergency and asked if he needed further help. He stated no and I terminated the patch. I advised the flm of what was going on. I VHF'd the 30 right deviation into the flights profile. The air carrier advised on course at FL370. Recommendation; the ZNY traffic management unit should be more proactive in metering traffic on oceanic non-radar airways when there is weather. There was a significant tropical storm over the ocean a having far-reaching impact on oceanic traffic.
