DISCUSSION AND OUTLOOK
———————-
At 200 PM EDT (1800 UTC), the center of Tropical Storm Henri was
located by surface observations and and NOAA Doppler weather radars
near latitude 41.4 North, longitude 71.8 West. Henri is now moving
toward the northwest near 9 mph (15 km/h). A northwestward motion
with a decrease in forward speed is expected this afternoon. The
center of Henri is currently located inland over southwestern Rhode
Island. On the forecast track, Henri is expected to slow down
further and possibly stall near the Connecticut-New York border
tonight, with an east-northeastward motion across northern
Connecticut and southern Massachusetts on expected on Monday.

Data from Doppler radars and surface observations indicate that
maximum sustained winds have decreased to near 50 mph (80 km/h)
with higher gusts. Rapid weakening is expected now that Henri has
moved inland over southern New England.

Tropical-storm-force winds extend outward up to 125 miles (205 km)
from the center.

The latest minimum central pressure estimated from nearby surface
observations is 991 mb (29.26 inches).

HAZARDS AFFECTING LAND
———————-
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 rainfall amounts of 3 to 6
inches over portions of Long Island, New England, southeast New
York, New Jersey, and northeast Pennsylvania Sunday into Monday,
with isolated maximum totals near 12 inches. Heavy rainfall from
Henri may result in considerable flash, urban, and small stream
flooding, along with the potential for widespread minor to isolated
moderate river flooding.

STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide…

South shore of Long Island from East Rockaway Inlet, NY to Montauk
Point, NY…1-2 ft
North shore of Long Island from Flushing, NY to Montauk Point, NY
including Long Island Sound…1-2 ft
Flushing, NY to Merrimack River, MA including Narragansett Bay,
Buzzards Bay, Vineyard Sound, Nantucket Sound, and Cape Cod
Bay…1-2 ft

The deepest water will occur along the immediate coast in areas of
onshore winds, where the surge will be accompanied by large and
dangerous waves. Surge-related flooding depends on the relative
timing of the surge and the tidal cycle, and can vary greatly over
short distances. For information specific to your area, please see
products issued by your local National Weather Service forecast
office.

WIND: Tropical storm conditions are expected to continue in the
tropical storm warning area into tonight.

TORNADOES: The risk for a tornado or two continues today across
parts of southern New England.

SURF: Swells generated by Henri should diminish around Bermuda
later today. Swells are expected to increase across much of the
east coast of the U.S. and Atlantic Canada today and continue into
Monday. These swells could cause life-threatening surf and rip
current conditions. Please consult products from your local
weather office.
