What’s up with Henri
At the National Hurricane Center's 11 a.m. advisory, they have upgraded Henri to a Category 1 hurricane, with sustained winds of 75 mph, central pressure of 991, moving north northeast at 14 mph. He is about 453miles south of Montauk on the eastern tip of Long Island. Henri won’t take the usual out to see track due to that ridge of high pressure in the northern Atlantic and into eastern Canada. There is also that upper level low and trough to his west that will also help tug Henri west. Henri is over SST that is near 84°F. The Moderate shear that he has been battling, keeping him from becoming stacked (vertically aligned) has lessened. So, the environment should promote improving outflow. So, there is room for further deepening. As Henri moves farther north, he will move over cooler water, SST off the Coast of Long Island are 75°F. cool water doesn’t support tropical cyclone development, so he should weaken as approaches the Coast.The NHC center storm surge forecast is between 3 and 5 feet from Henri is possible from Flushing, New York, to Chatham, Massachusetts; and for parts of the North Shore and South Shore of Long Island. Could Henri still reach Category 2? Yes, but he’s time is running out. If Henri does attain Cat 2 status his storm surge could almost double.
Those closer to the Coast can expect wind gust of Tropical and hurricane force. While those inland for parts of far eastern New York State and Central and southern parts of New England can expect gust of tropical storm force. Those across northern parts of the region will see breezy conditions but they likely won't be damaging.
Henri will be slowing as it approaches the Coast, it will continue to slow and even stall for a bit over the region. This will add to the flooding worries.
Rainfall between 3 to 6 inches with isolated areas of 8 to 10 inches, especially for areas in northern New Jersey into Long
