11 PM NHC UPDATE ON HENRI: Current Data And Track
Henri is moving to the north as it approaches the southern New England coast by Sunday. The latest track has shifted even further west, with a landfall in Long Island and then central-western Connecticut by Sunday afternoon.
IMPACTS FROM HENRI
Please prepare now for the potential for wind damage and power outages, rainfall and storm surge flooding and significant beach erosion. We will also see large, dangerous waves and rip current risks at area beaches, starting as early as Saturday Evening
The extent of any impacts will be highly dependent on the exact track, intensity and timing of the storm, so continue to stay up to date with the latest forecast. With the track shifting more west, this will confine the very heavy rain totals out in central and western CT, and not as much rainfall for Rhode Island and southeast Mass.
Areas located to the West of the center of the storm will see the heaviest rain and highest rain totals. While areas located on the Eastern side of the storm will see stronger wind gusts and higher storm surge.
There is a high probability of Tropical Storm (39mph-74mph) strength winds along the coast and further inland throughout southern New England, while hurricane-force winds (70mph+) will also be a risk along the the immediate coastline and offshore
Increased wave heights combined with strong onshore wind will lead to the chance for significant storm surge as well as beach erosion. Water levels have the potential to be 3-5 feet above normal. This storm is also occurring at astronomical high tide with a nearly full moon, enhancing the risk of flooding, especially at high tide on Sunday evening.
The good news is that Saturday will be a quiet weather day to allow for preparations for Henri.
HOUR BY HOUR: Conditions for the next 36 hours »
Increasing clouds and some gusty winds developing later Saturday night (after midnight) By Sunday morning the outer rain bands will begin to spread inland with conditions expected to deteriorate through the day.
We will continue to fine-tune the forecast, so please stay tuned to updates on Henri.
