1. Current position, strength, central pressure and motion
At 9.00 PM ADT... Hurricane Bill was located near latitude 37.8 N
And longitude 68.3 W... About 376 nautical miles or 696 km south
southwest of Yarmouth Nova Scotia. Maximum sustained winds are
Estimated at 75 knots... 139 km/h... And central pressure at 961

3. Public weather impacts and warnings summary
Tropical storm warnings are in effect for Atlantic coastal Nova
Scotia with wind speeds of 65 km/h with gusts to 90.
Hurricane watches are continued for eastern mainland Nova Scotia
And Southern Cape Breton with potential wind speeds of 120 km/h
With gusts to 140.
Tropical storm watches remain in effect for the remainder of nova
Scotia.. Eastern Prince Edward Island and the southern half of
Newfoundland with potential wind speeds of 70 km/h with gusts to 100.
Storm impacts:
Rainfall...
On Sunday the centre of hurricane Bill is expected to pass just south
of Nova Scotia giving rainfall amounts of 75 to 100 mm over nova
Scotia..Pei and Newfoundland except for Nova Scotia where local
Amounts up to 150 mm are possible. As a result.. Local flooding
Can be expected in flood-prone areas. Heavy downpours will reduce
visibilities and lead to standing water presenting a hazard to
motorists. Heavy rainfall has the potential to cause street
Flooding..Road washouts and flooded basements.
Winds...
With strong east to northeasterly winds over Nova Scotia we are
likely to see some tree branches breaking and possible downed
Utility lines. Please stay tuned in the event that the storm
Behavior changes where the wind threat could increase.
Coastal surf and surge...
A combination of storm surge (of 0.5 to 1.0 metres) and heavy
Surf along the Atlantic coast of Nova Scotia and Southern
Newfoundland (from large waves ranging from 5 to 10 metres)
Is expected. These conditions may lead to shoreline erosion
And damage to docks as well as generate dangerous rip currents
At local beaches. It is worthy to note that spring tides are
Occurring over the weekend..Increasing the threat of
Coastal flooding.
Spectators are advised to keep a safe distance from the shoreline
Due to the rapid approach of large waves.
Further details are available in the public forecast bulletins.
4. Marine weather impacts and warnings summary
Hurricane force wind warnings are in effect near and south of
The hurricane track with wind speeds in the range of 65 to 75 knots.
Storm warnings are in effect for areas just north of the track.
Large waves generated by Bill over offshore waters will range from
10 to 14 metres south of the track. Further details are available in
the local sea state forecasts.
5. Technical discussion for meteorologists
A. Analysis
Satellite pictures indicate that the highest winds in Bill have
Decreased.. But the overall cloud pattern remains very impressive.
According to the national hurricane centre assessment.. The
Intensity is 75 knots or 140 kmh.
The favourable factors driving Bill indicate that it will
Maintain its intensity this evening but a gradual weakening is
anticipated on Sunday. The track is maintained close to the national
hurricane centre track as well as its intensity.
B. Prognostic
Hurricane Bill will maintain its intensity for the next
12 hours then weaken gradually as it moves northeastward
Over colder water on Sunday. We continue to follow
The nhc track which is consistent with the previous tracks.
Our confidence in the track and intensity is enhanced by
The numerical models consistent track and intensity as well.
We expect extra tropical transition to be delayed until Sunday
Night given that the hurricane will remain embedded in the ambient
tropical airmass that has been present over Eastern Canada for
several days. This implies that Bill will retain tropical
characteristics longer than usual. It is also worthy of note that
Bill has a large circulation based on quikscat imagery.
C. Public weather associated
The anticipated tropical nature of Bill and its delayed transition
To post tropical will likely dictate a close-to-track rainfall
maximum over Nova Scotia.

Re: ATL: HURRICANE BILL (03L)
Bill clearly looks to be moving NNE this evening. Continued weakening is in the cards for Bill. Just talked with my middle son who was out surfing today in Va Beach. He said there 8-10 foot waves......MGC

THE CYCLONE SHOULD BE WELL INTO THE TRANSITION PROCESS BY EARLY
MONDAY AS IT MOVES AWAY FROM NEWFOUNDLAND. THE OFFICIAL INTENSITY
FORECAST SHOWS SLOW WEAKENING THROUGH 24 HOURS DUE TO COOLER SEA
SURFACE TEMPERATURES AND INCREASING VERTICAL WIND SHEAR. BEYOND
THAT TIME...A MORE SIGNIFICANT DECREASE IN INTENSITY IS FORECAST...
ALONG WITH A LARGE EXPANSION OF THE 34-KT WIND RADII...AS BILL
COMPLETES EXTRATROPICAL TRANSITION.
LARGE SWELLS GENERATED BY BILL ARE STILL AFFECTING THE EAST COAST OF
THE UNITED STATES. THESE SWELLS WILL CONTINUE TO SPREAD NORTHWARD
INTO THE CANADIAN MARITIMES ON SUNDAY...CAUSING EXTREMELY DANGEROUS
SURF AND LIFE-THREATENING RIP CURRENTS. PLEASE CONSULT STATEMENTS
ISSUED BY YOUR LOCAL WEATHER OFFICE AND METEOROLOGICAL SERVICES FOR
MORE DETAILS.

Will be interesting to see how accurate the below is........
Storm Watch Information
Hurricane Bill has weakened to a strong Category 1 storm after passing Bermuda Friday night. Some fluctuation in strength could occur over the next 24 hours but Bill is expected to weaken as it moves into cooler waters.
Hurricane Bill could still be a significant storm, even stay a Category 1 hurricane, when it passes or makes landfall in the Maritimes late Sunday.
The current storm track has Bill brushing the coast of Nova Scotia near Halifax late Sunday evening and hitting Newfoundland Monday morning.
The Maritimes
Rain is forecast to begin in Nova Scotia early Sunday morning. Storm surge along the eastern coast of Nova Scotia from Halifax to Sydney could raise ocean levels by 3-4 m at the height of the storm. Rainfall amounts could reach 140 mm locally in the hardest hit areas in Nova Scotia and PEI. Flooding will be a serious concern. Less affected areas of New Brunswick and western PEI could see up 50 mm of rain.
Wind is another serious concern with gusts expected between 110-130 km/h in the hardest hit areas from Yarmouth to Sydney along the coast. Hurricane force winds could cause significant damage and power outages are likely.
Newfoundland
Hurricane Bill may no longer be officially a hurricane when it makes landfall near St. John's early Monday morning but it will be a significant tropical storm packing winds gusts up to 130 km/h. Rain amounts could be up to 100 mm locally before the storm moves out into the Atlantic.
Residents of Atlantic Canada, in particular Nova Scotia, PEI, eastern New Brunswick and all of Newfoundland should be prepared for a potential weather emergency. These preparations should include an Emergency Kit with enough food and water for 72 hours at least. Do not wait to prepare yourself.
Be sure to stay tuned to The Weather Network where we will be covering Hurricane Bill extensively including live coverage from the Maritimes as well as interviews with staff from the Canadian Hurricane Centre in Halfiax. Hurricane Bill's storm track could change so check regularly to find out how this storm will affect you.
Current Hurricane Bill Statistics
Hurricane Bill is currently a strong Category 1 storm located 415 km south or Nantucket, MA and about 880 km south-southwest of Halifax. The storm has increased its forward speed and is traveling north at about 39 km/h. This motion is expected to continue today until Bill gradually begins to turn north-northeast on Sunday.
Bill's wind speeds have slowed slightly with max. sustained winds measuring 140 km/h. The storm's impact is still significant with hurricane force winds extending 140 km from the centre of the storm, and tropical storm force winds extending 445 km from centre.
Hurricane Bill will probably lose hurricane status either before or shortly after making landfall in Newfoundland on Monday. The remnants of the storm will move across the Atlantic to impact the north of England Wednesday.
Tropical Storm, Rainfall and Hurricane Watches and Warnings are in effect across Atlantic Canada.

Bill is now experiencing the force of the trough, which not only accelerates the storm northeastward but also allows the hurricane to intensify as if it were a non-tropical cyclone. This is why we have seen an increase in the intensity of the convection. Still, Bill is unlikely to increase in intensity, at least significantly.
