Hurricane Bill intermediate information statement issued by the
canadian hurricane centre of Environment Canada at 6.00 PM ADT
Sunday 23 August 2009.

The next statement will be issued by 9.00 PM ADT

At 6.00 PM ADT... Hurricane Bill was located near latitude
45.1 N and longitude 60.8 W... About 40 nautical miles or 70 km
South of louisbourg Nova Scotia.

Bill is accelerating towards the northeast at 30 knots... 55 km/h.
Maximum sustained winds are estimated at 65 knots... 120 km/h and
central pressure at 970 MB.

The eye of hurricane Bill became evident on conventional radar
imnagery from gore Nova Scotia early this afternoon and at its
closest approach was 75 kilometres south of the Halifax regional
municipality.

Hurricane Bill continues to race northeastward just off the coast
Of Guysborough County and has become very sheared to the east..
However it remains very tropical with no evidence of baroclinicity.
There is very little precipitation remaining on the west side. The
storm rainbands have contracted somewhat but the spatial coverage
Of the rainfall near the centre of Bill is expanding.

The centre of hurricane Bill passed south of the Georges Bank
Buoy between 08 and 09 UTC then south of the Browns Bank buoy
Between 10 and 12 UTC. The centre then passed north of the Lahave
Bank buoy between 12 and 13 UTC. That buoy recorded a maximum
significant wave of 13.4 metres with a maximum wave height of
26.4 metres and a maximum wind speed of 73 knots. This was the
highest reported wind speed from the buoy netwrok through to
20Z. The highest significant wave height reported by the Environment
Canada offshore buoy network up to 20 UTC was 14.1 metres on the east
Scotian Slope.

The storm and hurricane force winds and large waves in the
Southern quadrant of hurricane Bill are forecast to spread into
The eastern marine district of the Maritimes early this evening
And to the waters of Southeastern Newfoundland tonight. The envelope
of high seas carried with hurricane Bill will strike coastal regions
of Newfoundland facing the brunt of Bill. A storm surge warning is
In effect for the southeasternmost portions of Newfoundland as the
centre of Bill is expected to track across land there.

Rainfall.. Southern Nova Scotia was battered by rainbands from
hurricane Bill this morning where rainfall rates of 15 to 20
millimetres per hour caused localized flooding of streets and
Roads and some basements. Some road surfaces were washed away.
Rainfall totals in the rainbands were in the 50 to 75 mm range.
The highest official rainfall total by 18 UTC was 65.2 mm at
Yarmouth airport. Rainbands and torrential rainfalls from Bill moved
in Halifax regional municipality before noon causing some catch
basins to overfill and streets to flood. Localized property flooding
was
Also reported due to the rapid rainfall rates. Total rainfall
Amounts across the hrm were near 55 millimetres. Rain from Bill moved
into the eastern sections of Nova Scotia
And Cape Breton this afternoon and complete totals are not yet
available. Rainfall rates of 15 to 25 millimetres per hour
Can be expected making driving conditions hazardous with reduced
visibilities and standing water on roadways. This heavy rainfall
Has the potential to cause street and road flooding.. Undermine
Some road surfaces.. Washouts and flooded basements. The outer edges
of the rain from Bill reached Prince Edward
Island and Northern Nova Scotia where rainfall totals island
Were lower than areas of Nova Scotia. Total rainfall amounts
Will be available at 00 UTC. One outer rainband from hurricane Bill
also stalled across
Southern New Brunswick for a time this morning. High rainfall
Amounts were very localized with Moncton receiving 30 millimetres
And St Stephen reporting 35 millimetres. Meanwhile Saint John
received only 6 millimetres as the rainband was to their north
And the rain from Bill never made it across the Bay of Fundy. Heavy
rainfalls will reach much of Newfoundland tonight where localized
amounts could still exceed 100 mm.

Winds.. Tropical storm force winds were reported in many areas
Of Nova Scotia. In Southern Nova Scotia.. Yarmouth airport and
Lunenburg reported 43 knots (80 km/h).. And Baccaro Point 46 knots
(85 km/h). Across the Halifax regional municipality the highest
recorded wind was 47 knots (87 km/h). The strongest winds have
Just moved into Eastern Nova Scotia.. Prince Edward Island and
Cape Breton. At the height of the storm.. Nova Scotia power
Reported 10 of thousands of customers without power. There were
reports of trees down in some areas while flights and ferry
Services were canceled in most regions for some time.
For southeastern regions of the Newfoundland.. From east of harbour
Breton to Bonavista with potential wind speeds of 70 km/h with
Gusts to 100 and local wind gusts to 120 km/h over exposed
Coastal areas to the south of the storm track. Elsewhere over the
island except the Northern Peninsula there is potential for gusts
To 90 km/h.

Waves and storm surge.. Large waves reported over all sections
Of coastal Nova Scotia. The buoy outside of Halifax harbour reported
a significant wave height of 9.0 metres at 18 UTC with a maximum
Wave height of 14.9 metres. These large waves inundated some
Roadways and forced local police services to close many coastal
roads. There were reports that a road along Bedford Basin in
Halifax was also underwater. The waves are now subsiding from
Halifax westward but the eastern shore and Cape Breton can
Expect these conditions for a few more hours this evening.
The combination of storm surge (0.5 to 1.0 metres) and heavy
Surf (significant waves ranging from 5 to 10 metres) is also
Expected in Southern Newfoundland. These conditions may lead to
shoreline erosion and damage to wharves and coastal structures as
well as generating dangerous rip currents at local beaches. It is
Worthy to note that spring tides are occurring this weekend..
Increasing the threat of coastal flooding. A storm surge warning has
been issued for the area around
Placentia Bay and the Burin Peninsula in Newfoundland as the
Large waves combine with storm surge from Bill to raise
Water levels 50 to possibly 90 centimetres above high tide
Near midnight.

Spectators are strongly advised to keep a safe distance
From the shoreline due to the rapid approach of large waves.

Public and marine interests are advised to monitor forecasts
And warnings issued for their region by Environment Canada.

SHORELINE EROSION AND DAMAGE TO WHARVES AND COASTAL STRUCTURES AS
WELL AS GENERATING DANGEROUS RIP CURRENTS AT LOCAL BEACHES. IT IS
WORTHY TO NOTE THAT SPRING TIDES ARE OCCURRING THIS WEEKEND..
INCREASING THE THREAT OF COASTAL FLOODING.
A STORM SURGE WARNING HAS BEEN ISSUED FOR THE AREA AROUND
PLACENTIA BAY AND THE BURIN PENINSULA IN NEWFOUNDLAND AS THE
