east-northeast Monday afternoon.  A faster motion toward the 
east-northeast is expected on Tuesday.  On the forecast track, Henri 
is expected to slow down further and possibly stall near the 
Connecticut-New York border tonight, then move across Massachusetts 
on Monday afternoon and Monday night and over the Atlantic on 
Tuesday.
 
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.
Some additional slow weakening is likely during the next couple of
