The powerful nor'easter is still intensifying as it moves north, with Long Island and coastal New England bracing for a hard hit after major flooding along the Jersey Shore. FOX News Hurricane Specialist Bryan Norcross says a long-duration stretch of powerful winds and multiple high-tide cycles could keep coastal flooding a major threat well into tomorrow. Long Island could see winds of 50 to 60 mph, while shifting winds could push water into Long Island Sound and potentially flood runways at LaGuardia Airport around midday tomorrow. Water levels are already running nearly five feet above normal high tide at Sandy Hook and three feet above normal at the southern tip of Manhattan. Follow the nor'easter's path: ▻
