Hurricane Warnings Most of Long Island Connecticut

Tropical Storm Warnings NYC to Manasquan NJ

Hurricane Warnings continue for most of Long Island and Connecticut. Tropical Storm Warnings are up either side of the Hurricane Warning area and now include NYC and the New Jersey counties surrounding NY Harbor south to Manasquan. Flash Flood Watches are now up for New Jersey as the heaviest rains will fall west of the storm track.

Some rather impressive rainfall amounts are being indicated by NWS digital forecasts. There are two areas to pay attention. One along and just west of the storm track. The other is inland north and west of the track where we start to encounter elevation. This will create extra lift and could potentially squeeze our a lot of rain for somebody. This explains why we are seeing big rains north up the Connecticut River Valley. Enhancement of rain could also occur in Northern New Jersey and into Eastern Pennsylvania which is where an upper air low is going to be tracking north northeastward at the same time.

We have seen little change in Henri overnight. After two days of strong northeasterly wind shear, even though the shear has relaxed, Henri has not shown strengthening overnight. The window for strengthening is closing once Henri gets north of 36 degrees north. Water temperatures cool north of this line and will not support strengthening. In the meantime today it will be another warm and very humid day as the atmosphere basically primes itself for Henri. Highs will be in the 80s. Watch for passing showers or a scattered heavier downpour.

The first bands of Henri are beginning to appear on the regional radar east of North Carolina and Virginia and they will gradually spread northward as the day wears on. Tonight clouds will thicken up and weather conditions will begin to deteriorate from southeast to northwest during the early morning hours Sunday.

I could have pulled any model and no two had the same track so I opted for the HRRR model from 1pm today through 1am Monday. It illustrates the idea that heaviest rain will be to the west and stronger winds will be to the east. Landfall will be sometime Sunday morning and I think the NHC forecast is ok at this point with the center cutting across Central Long Island.

With regards to storm surge of 2 to 4 feet it will occur east of the track of the storm so mainly from the coast of Central Long Island eastward to Block Island. The wind in the opposite direction on the west side will blow the water out. Remember if the track is further west you will have to adjust the western boundary of the surge.
