Hurricane Henri has now been down graded to a tropical storm based on top winds of 70 mph as of the 7am update from the National Hurricane Center. At this point everything is underway. The storm is elongated east west reflecting the pull of the upper low in the Mid Atlantic. The worst of it from the standpoint of wind will be from now until landfall somewhere in Southeastern Connecticut or Rhode Island after a pass near the East of Long Island. I think the biggest issue with Henri will be heavy rains of several to many inches. Flash Flood Watches cover almost all of Eastern Pennsylvania, New Jersey, the Hudson Valley an much of Southern and Central New England.

Bands of heavy rain and gusty winds are arcing back westward across Long Island and into New Jersey Connecticut and the Hudson Valley. Henri’s slow movement means that some places will be piling up the rain in inches. As the stronger bands arrive winds will be gusty at times though the strongest winds will be closer to the center of the storm.

The slowing movement of Henri will prolong rain and rack up some big totals in areas mostly to the west and well away from the actual track of the center. Several to 6 inches of rain are possible when this is all said and done and it would not surprise me at all to see some double digit amounts in some of the elevated areas in Connecticut, the Hudson Valley, and possibly even into Northern New Jersey.

As far as the winds are concerned, the strongest winds will occur into mid afternoon. The map below shows wind gusts forecast for 12 noon which is around the time that Henri will be crossing the easternmost portion of the twin forks on Long Island. Gusty winds will extend westward back through Suffolk County in Western Nassau as well as the coasts of Connecticut and Rhode Island.

Rain and wind will last into the late afternoon and evening until the storm center moves into Connecticut and weakens. This will eventually push the arc of rain back northwestward. Be sure to tune into the Joe & Joe Weather Show at 10:30am Eastern Time for another update on Henri.
