DISCUSSION AND OUTLOOK

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).

HAZARDS AFFECTING LAND
———————-
RAINFALL: Henri is expected to produce storm total rainfall of 3 to 6 inches with locally higher amounts expected over portions of Long Island, New England, southeast New York, New Jersey, and northeast Pennsylvania Sunday into Monday. Isolated maximum totals of 10 to 12 inches are possible across northern New Jersey into southern New York. Heavy rainfall from Henri will continue to result in considerable flash, urban, and small stream flooding, along with the potential for additional minor to isolated moderate river flooding.

SURF: Swells are expected to continue across much of the east coast of the U.S. and Atlantic Canada tonight and continue into Monday. These swells could cause life-threatening surf and rip current conditions.
