DISCUSSION AND OUTLOOK
----------------------
At 200 AM EDT (0600 UTC), the center of Hurricane Henri was located
near latitude 39.3 North, longitude 71.0 West. Henri is moving
toward the north near 21 mph (33 km/h).  A decrease in forward 
speed and a turn toward the north-northwest is expected later this 
morning. On the forecast track, Henri is expected to make landfall 
in southern New England or on Long Island today.  After landfall, a 
turn to the north and a slower forward speed are expected as Henri 
moves over southern New England.

Reports from Air Force Reserve Hurricane Hunter aircraft indicate 
that maximum sustained winds are near 75 mph (120 km/h) with higher 
gusts.  Slight strengthening is possible early this morning. 
Weakening is expected to begin later today. However, Henri is 
expected to be at or near hurricane strength when it reaches the 
coasts of southern New England and Long island.  Rapid weakening is 
expected after Henri makes landfall.

Hurricane-force winds extend outward up to 35 miles (55 km) from
the center and tropical-storm-force winds extend outward up to 150
miles (240 km).

The latest minimum central pressure estimated from data from 
an Air Force Reserve Hurricane Hunter aircraft is 987 mb (29.15 
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.

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...

Flushing, NY to Chatham, MA including Narragansett Bay, Buzzards
Bay, Vineyard Sound, and Nantucket Sound...3-5 ft
North shore of Long Island from Flushing to Montauk Point, NY
including Long Island Sound...3-5 ft
South shore of Long Island from Mastic Beach to Montauk Point,
NY...3-5 ft
Chatham, MA to Sagamore Beach, MA including Cape Cod Bay...2-4 ft
South shore of Long Island from East Rockaway Inlet to Mastic Beach,
NY...2-4 ft
Cape May, NJ to East Rockaway Inlet, NY...1-3 ft
Sagamore Beach, MA to Merrimack River including Massachusetts
Bay...1-3 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:  Hurricane conditions are expected in the hurricane warning
area today, with tropical storm conditions beginning within the 
next few hours.  Tropical storm conditions are expected in the 
tropical storm warning area beginning this morning and continuing 
into tonight. 

RAINFALL:  Henri is expected to produce rainfall amounts of 3 to 6
inches over portions of Long Island, New England, southeast New
York, and New Jersey today into Monday, with isolated maximum
totals near 10 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.

TORNADOES:  A tornado or two may occur today over southern 
New England.

SURF:  Swells generated by Henri should continue to affect Bermuda
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.

I just hit the 1.01" mark for rain as I'm on the SW side of the deathband but still getting the moderate rain.  When the light returns began here yesterday before I went offline, I had 0.01" in the bucket.  As of midnight, ended up with 0.07" total for yesterday and am now at 1.08" at post time, for the event.

1.25" overnight, currently steady rain which looks to have been the case for much of the night. Maybe will see some heavy stuff this morning as it pivots? 

Will have to see if the pivot maintains the moisture funnel as it seems Mt. Holly was suggesting it could start drying up by the western-most parts as the system lifts to the north.

What is throwing the wrench in nailing how it sets up is the ULL south of here that is helping to feed moisture up this way.

  • Hurricane Agnes changed the title to Tropical Storm Henri (as of 7 am EDT 8/22) - 8/21 - 8/23 (70 mph, N 18 mph, 986 mb)

Steady rain falling here in Media Delaware County 0.82" so far.  It looks like the rain band is shrinking.  Strange set up looks like the southern portion of the band is lifting north at like 5 mph and then where the back edge of the band over the area moving north you have individual segments ripping off and moving SSE.  I am guessing this is in response to Henri getting further north of us an the Upper Level low collapsing a bit.

0.37" here event total so far after being tickled by the southern edge of that Atlantic fire hose since about 2 am. Most rain this month in a single event so far, puts mby at 1.41" for the month. Maybe more later on, we shall see - pretty much done for the moment. Nice morning all things considered, 71F currently.

Will have to see if that band pivots any further south.  I'm up to 1.39" for the day so far although the rate is very light/misty at the moment.  This plus yesterday's 0.07" has me at 1.46" so far for the event and now at a whopping 8.31" for the month of August, with 10 days left, an not even at the peak of hurricane season! :o

progress of Henri.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 800 AM EDT (1200 UTC), the center of Tropical Storm Henri was 
located by reconnaissance aircraft and NOAA Doppler weather radars 
near latitude 40.7 North, longitude 71.3 West. Henri is moving 
toward the north-northwest near 16 mph (26 km/h). A north- 
northwestward motion with a decrease in forward speed is expected 
this morning. On the forecast track, Henri is expected to make 
landfall in southern New England or on Long Island later this 
morning or early this afternoon.  After landfall, a turn back toward 
the north and an even slower forward speed are expected as Henri 
moves over southern New England.

Maximum sustained winds are near 70 mph (110 km/h) with higher 
gusts.  Some slight weakening will be possible this morning, but 
Henri is still forecast to be a strong tropical storm when it 
reaches the coasts of southern New England and Long island.  Rapid 
weakening is expected after Henri makes landfall.

Tropical-storm-force winds extend outward up to 125 miles (205 
km). A Weatherflow station on Block Island, Rhode Island, recently 
reported a sustained wind of 41 mph (66 km/h) and a gust to 50 mph 
(80 km/h). A Weatherflow station near Narragansett, Rhode Island, 
recently measured a sustained wind of 44 mph (71 km/h) and a gust to 
55 mph (89 km/h). 

The latest minimum central pressure estimated from Air Force 
Reserve reconnaissance aircraft data is 986 mb (29.12 inches).

Well I am happy that the rain hasn’t been catastrophic.  More will come but looks manageable. 

Yeah, about 1.80” of a nice, soaking rain here. Let’s build up soil moisture before the heat moves back in this week.

DISCUSSION AND OUTLOOK
----------------------
At 1100 AM EDT (1500 UTC), the center of Tropical Storm Henri was 
located by an Air Force Reserve reconnaissance aircraft and NOAA 
Doppler weather radars near latitude 41.1 North, longitude 71.6 
West. Henri is moving toward the north-northwest near 12 mph (19 
km/h). A north-northwestward motion with a decrease in forward speed 
is expected for the next few hours, followed by a turn toward the 
northwest this afternoon. The center of Henri is currently passing 
near Block Island and on the forecast track the center is expected 
to make landfall in Rhode Island by early afternoon.  Henri is 
forecast to slow down and possibly stall near the Connecticut-New 
York border tonight, followed by an east-northeastward motion across 
northern Connecticut and southern Massachusetts on Monday.

Data from the aircraft, Doppler radars, and surface observations 
indicate that maximum sustained winds have decreased to near 60 mph 
(95 km/h) with higher gusts. Little change in strength is expected 
until landfall occurs, followed by rapid weakening after Henri moves 
inland over southern New England.

Tropical-storm-force winds extend outward up to 125 miles (205 km) 
from the center.  A Weatherflow station on Block Island, Rhode 
Island, recently reported a sustained wind of 52 mph (84 km/h) and 
a gust to 65 mph (105 km/h).  Another Weatherflow station near Point 
Judith, Rhode Island, recently measured a sustained wind of 51 mph 
(82 km/h) and a gust to 69 mph (111 km/h). The NOAA C-MAN station at 
Buzzards Bay, Massachusetts, recently measured a sustained wind of 
49 mph (79 km/h) and a gust to 57 mph (92 km/h), while an amateur 
radio operator in Westport, Massachusetts, recently reported a  
sustained wind of 41 mph (66 km/h) and a gust to 62 mph (100 km/h).

The latest minimum central pressure estimated from Air Force
Reserve reconnaissance aircraft data is 987 mb (29.15 inches).

with water reported in the streets in some areas of the city.

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

damage has already been reported across southern Rhode Island.

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.

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
