DISCUSSION AND OUTLOOK
----------------------
At 500 PM EDT (2100 UTC), the center of Tropical Storm Henri was 
located by surface observations and and NOAA Doppler weather radars 
near latitude 41.6 North, longitude 72.4 West. Henri is moving 
toward the west-northwest near 7 mph (11 km/h), and this general 
motion with a decrease in forward speed is expected through early 
Monday morning. A slow turn toward the north is expected Monday 
morning, followed by a motion toward the east-northeast Monday 
afternoon. On the forecast track, Henri is expected to slow down 
further and possibly stall near the Connecticut-New York border 
tonight, then move across northern Connecticut or southern 
Massachusetts by Monday afternoon.
 
Maximum sustained winds have decreased to near 40 mph (65 km/h) with 
higher gusts. Additional weakening is forecast during the next 
couple of days, and Henri is expected to become a tropical 
depression this evening and degenerate into a post-tropical remnant 
low by Monday afternoon.
 
Tropical-storm-force winds extend outward up to 35 miles (55 km)
from the center, mainly over Long Island Sound. A sustained wind of 
29 mph (47 km/h) and a gust to 42 mph (68 km/h) were recently 
measured by a private weather station at Orient Point on eastern 
Long Island.
 
The estimated minimum central pressure based on nearby surface 
observations is 997 mb (29.44 inches).

Island, New England, southeast New York, New Jersey, and northeast
Pennsylvania Sunday into Monday. Isolated maximum totals of 10 to 12
