Hermine's Track, Timeline Shifts, What That Means for Long Island [LIVE BEACH CAM]

Post-Tropical Cyclone Hermine is still expected to deliver significant impacts to the Long Island coast, but the latest storm track from the National Hurricane Center keeps Hermine further offshore and delays any impacts from the storm until at least Sunday night.

As of 8 a.m. Sunday, Hermine was off the Virginia coast with maximum sustained winds of 65 mph. Hermine, which is currently moving east-northeast at 12 mph, had been expected to re-strengthen into a hurricane by Sunday afternoon, but the NHC now says the storm likely won't reach hurricane status (winds of 74 mph or more) until Monday afternoon.

The latest storm track is certainly welcome news for Long Island, which has seen increasingly dire forecasts in recent days, but Hermine remains a serious storm with the potential to deliver a devastating blow to areas along the coast.

"Small changes in the meandering track of Hermine could result in large differences in the impacts along the mid Atlantic coast during the next several days," the NHC said.

Tropical storm conditions that had been expected on Sunday are now not expected to materialize until overnight into Monday. Sunday will be partly sunny and breezy on Long Island with a high near 77, but officials are urging those on Fire Island to leave now. A voluntary evacuation of the island is ongoing.

Here are the current likely storm impacts on Long Island, which remains under a tropical storm warning, according to the National Weather Service:

• Moderate to locally major coastal flooding is expected from Sunday night into at least Tuesday
• Life-threatening surge of 2 to 4 feet having possible significant impacts across low-lying coastal communities along the South Shore and eastern bays of Long Island, well as oceanfront and barrier island communities
• Strong gusty winds are likely, with gusts of 40 to possibly 50 mph likely near the South Shore late Sunday night into Monday morning
• Significant beach erosion
• Dangerous rip currents through at least mid-week (all ocean beaches are closed to swimmers as of Sunday)

The rain threat with Hermine continues to diminish, the NWS says.

"The priority will be coastal flooding," Long Island meteorologist Joe Cioffi wrote on his website. "Wind will only be an impact along the immediate coast, and rain is not going to be much of an impact at all."

Hermine is forecast to begin lifting to the northeast on Wednesday and cloud cover/any precipitation will diminish fairly rapidly as it exits, the NWS says.
