SUMMARY
DISCUSSION

1. Heavy rainfall will continue to lead to considerable flash, urban, and small stream flooding, along with the potential for additional minor to isolated moderate river flooding over portions of Long Island, New England, eastern New York, New Jersey and northeast Pennsylvania.


There are no coastal watches or warnings in effect.


Key messages for Henri can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC and on the web at www.hurricanes.gov/graphics_at3.shtml?key_messages.

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 through 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 into Monday. These swells could cause life threatening surf and rip current conditions. Please consult products from your local weather office.


At 1100 PM EDT (0300 UTC), the center of Tropical Depression Henri was located near latitude 41.9 North, longitude 73.2 West. The depression is moving toward the west northwest near 8 mph (13 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. 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 days. The minimum central pressure based on nearby surface observations is 1002 mb (29.59 inches).


Henri has continued to weaken over land and synoptic surface observations indicate that its maximum winds have decreased to near 25 kt. A little more weakening is likely during the next 48 hours, and simulated satellite imagery from the global models indicate that the system will be post-tropical after its expected re-emergence into the Atlantic in 36 hours or so. Beyond 48 hours the dynamical guidance suggests that the system will lose its identity.

Satellite imagery and surface data indicate that the center is moving slowly west-northwestward, or 290/7 kt. Henri is interacting with another cyclonic circulation over the northeastern United States. As a result of this interaction, the tropical cyclone is expected to briefly come to a halt overnight, turn toward the east-northeast on Monday, and continue an east-northeastward motion into Tuesday. The official forecast track is similar to the dynamical model consensus, TVCN.

Although Henri's winds are weakening, the cyclone will still continue to be a prolific rain producer, resulting in significant flooding across southern New England and portions of the northern mid-Atlantic states for the next day or two.

This is the last advisory by the National Hurricane Center on Henri. Future information on this system can be found in Public Advisories issued by the Weather Prediction Center beginning at 5 AM EDT, under AWIPS header TCPAT3, WMO header WTNT33 KWNH, and on the web at http://www.wpc.ncep.noaa.gov.
