At 800 PM EDT (0000 UTC), the center of Tropical Depression Henri 
was located by surface observations near latitude 41.7 North, 
longitude 72.8 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 35 mph (55 km/h)
with higher gusts.  Additional weakening is forecast during the next
couple of days.

The estimated minimum central pressure based on nearby surface
observations is 1000 mb (29.53 inches).
