Hurricane Bill information statement issued by the canadian
Hurricane centre of Environment Canada at 3.00 PM ADT Thursday
20 August 2009.

The next statement will be issued by 9.00 PM ADT

Correction to initial position and pressure.

...Hurricane Bill expected to impact Atlantic Canada on Sunday...

1. Current position, strength, central pressure and motion

At 3.00 PM ADT... Hurricane Bill was located near latitude 23.2 N
And longitude 62.6 W... About 310 nautical miles or 575 km
North of st maarteen. Maximum sustained winds are estimated at 105
Knots... 194 km/h... And central pressure at 951 MB. Bill is moving
Northwest at 16 knots... 30 km/h.

2. Forecast position, central pressure and strength

The latest track of hurricane Bill has the storm moving slightly
southeast of the previous position over Newfoundland. However
Given the fact track errors are somewhat large beyond day three
One should not focus on the exact path.

3. Public weather impacts and warnings summary
At this point it is too early for warnings to be issued as Bill
remains well to our south.

Swell from hurricane Bill will arrive along the Atlantic coast
Of Nova Scotia early Friday. By Saturday approaching swell heights
near 2 m will generate rough surf and hazardous rip currents along
some beaches. Breaking wave heights on the shoreline are expected
To be from 2 to 3 m (7 to 10 feet) along the Atlantic coast of
Nova Scotia on Saturday. Residents are advised to exercise caution
where large waves break onshore.

4. Marine weather impacts and warnings summary
Given the current CHC track hurricane Bill is expected to impact
maritime marine areas later this weekend, however it is too early
To issue warnings.

5. Technical discussion for meteorologists

A. Analysis
Currently following nhc.

B. Prognostic
Following nhc on both track and intensity.

Bill is tracking northwestward north of the leeward islands and
Is expected to continue on this path for the next day or two. After
that a deep-layer trough is forecast to move over the eastern
United States while an upper-level ridge builds over the Atlantic.
These two features will steer Bill northward and eventually
northeastward later in the forecast period. Track guidance is
Tightly clustered for the first couple of days but then becomes
divergent on both direction and speed later in the forecast period.

Cyclone phase space diagrams indicate Bill will begin to undergo
extra-tropical transition on the 23rd and will be completed early
On the 24th.

C. Public weather
Nothing to say at this point.

D. Marine weather

[KWT]

If you look at the loops you'll Upper level lows rotating counter clockwise which is the signature of low pressure cells. You can see that on the loops to the WNW of Bill.

[thetruesms]

So ULL 's are represented by the black/ uncoloured areas and storms are pushed/ pulled/ move to try and find them (appreciate that may just be one of many factors)...?

The ULL's aren't determined by the amount of moisture present, but the flow about them. It's kind of hard to pick out in the still image, but if you play the loop, you can clearly see the cyclonic (since we're in the northern hemisphere, counter-clockwise) flow around it. It just happens that this ULL doesn't have much moisture with it, and appears black.

As far as how that affects storm motion - absent any other forcing, low pressure systems (like Bill) will tend to move to where the pressure is falling. As the ULL moves, it causes pressures to fall, which could draw Bill towards those falling pressures. Of course, this explanation is simplified almost to the point of being wrong - there are many other factors at play that influence storm track, otherwise hurricanes would just follow these things around all over the Atlantic. But, it can be a factor that could potentially nudge Bill's track somewhat.

appreciate the dumbed down version best - it suits my simple (lol) mind. At the same level would the 'trough' that is being spoken about be the large band of moisture (front? depression?) over the E USA now?

Also understand that there are many other - and probably (far) more likely - things that may/will influence this storm but a guys gotta start somewhere!

[Cainer]

Our local radio station has been putting out disclaimers about Bill, advising the public to tie up loose objects, board up loose windows and prepare for a few days without power. As far as I can tell, the town is taking the threat from Bill pretty seriously, so hopefully no one will be caught unawares when Bill hits.

On a lighter note, I was looking at the website for the radio station, and their article on Bill is a little off - they have a picture of Hurricane Bill from 1997 . Here's the link if you guys wanted to check it out for yourselves: http://www.cjls.com/news.php?ID=621

As for me, our house is next to the beach, but thankfully there's a big hill and a marsh ready to stop any storm surge from reaching our house. On the other hand, our house is basically made of big windows, and falling trees are always a hazard as it is nestled in the forest. But as long as they don't fall on the house, the trees should help protect us from the strongest winds. We have our generator set up and ready for action if (or when ) its needed. I'll try my best to keep you guys updated throughout the weekend.

[cpdaman]

looks like a bit more TRUE NW motion last few images (maybe even 320 ish) ....IMO lets see if this wiggles back WNW next

[KWT]

Yeah I agree I'd go for about 315 myself, however Derek did say he expected this to possibly move back more to the WNW in about 12hrs time.

NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL032009
500 PM AST THU AUG 20 2009

BOTH NOAA AND AIR FORCE RECONNAISSANCE PLANES HAVE BEEN SENDING VERY
VALUABLE DATA FROM HURRICANE BILL. THE LATEST MINIMUM PRESSURE WAS
DOWN TO 948 MB AND THE PEAK FLIGHT-LEVEL WIND WAS 135 KNOTS. THE
SFMR REPORTED EARLIER A PEAK WIND OF 101 KNOTS. SINCE THEN...THE
SATELLITE PRESENTATION HAS IMPROVED AND THE EYE IS NOW BETTER
DEFINED. IN FACT...GOES SATELLITE SUPER-RAPID SCAN SHOWS THE
STRUCTURE OF THE EYEWALL AND SEVERAL MESOVORTICES INSIDE THE
EYE...TYPICAL OF STRONG HURRICANES. BASED ON THE AIRCRAFT DATA AND
THE CURRENT SATELLITE PRESENTATION...THE INITIAL INTENSITY IS
ADJUSTED UPWARD TO 110 KNOTS. THE LARGE SCALE ENVIRONMENT
CONTINUES TO BE CONDUCIVE FOR REINTENSIFICATION SINCE BILL IS ABOUT
TO ENCOUNTER THE WARMEST WATERS ALONG ITS PATH SO FAR.
FURTHERMORE...GLOBAL MODELS SHOW BILL EMBEDDED IN A WELL DEFINED
200 MB ANTICYCLONE. GIVEN THE FAVORABLE ENVIRONMENT...THE OFFICIAL
FORECAST CALLS FOR RESTRENGTHENING AND BILL IS EXPECTED TO REACH
CATEGORY FOUR STATUS AGAIN WITHIN THE NEXT 12 TO 36 HOURS.
THEREAFTER...THE HURRICANE SHOULD GRADUALLY BEGIN TO INTERACT WITH
A MID-LATITUDE TROUGH AND BY 96 HOURS IT SHOULD BE EXTRATROPICAL.

THERE IS PRACTICALLY NO CHANGE IN THE FORECAST TRACK. BILL IS MOVING
TOWARD THE NORTHWEST OR 305 DEGREES AT 16 KNOTS EMBEDDED IN VERY
STRONG AND WELL DEFINED STEERING CURRENTS AROUND THE SOUTHWESTERN
PORTION OF THE AZORES-BERMUDA HIGH. HOWEVER...IN A DAY OR SO A
LARGE MID-LATITUDE TROUGH IS EXPECTED TO SWEEP ACROSS THE EASTERN
UNITED STATES AND THE FLOW BETWEEN THE TROUGH AND THE SUBTROPICAL
HIGH SHOULD FORCE THE HURRICANE TO MOVE ON A NORTHERLY AND THEN
NORTHEASTERLY TRACK. THE DYNAMICAL TRACK GUIDANCE IS EXTREMELY
TIGHTLY CLUSTERED DURING THE FIRST 48 HOURS...INCREASING
CONSIDERABLY THE CONFIDENCE IN THE OFFICIAL TRACK FORECAST FOR THAT
PERIOD. ON THIS TRACK...THE CORE OF THE HURRICANE WILL MOVE OVER
THE OPEN WATERS BETWEEN BERMUDA AND THE EAST COAST OF THE UNITED
STATES SATURDAY MORNING AND BY SUNDAY...THE HURRICANE WILL BE
APPROACHING THE WATERS SOUTH OF NOVA SCOTIA.

LARGE SWELLS GENERATED BY THIS HURRICANE ARE AFFECTING THE NORTHERN
LEEWARD ISLANDS...PUERTO RICO...HISPANIOLA AND SHOULD BEGIN
AFFECTING THE BAHAMAS...BERMUDA...MOST OF THE EASTERN U.S.
COAST...AND THE ATLANTIC MARITIMES OF CANADA DURING THE NEXT FEW

Man you take the fun out of it. Love to see the little wibbles wobble but they don't fall down

[Shaun2453]

Heard a rumour that the trough of low pressure that is supposed to move Bill out to sea has transformed itself with a "negative tilt". I have no idea of the significance or this or even what it means in laymans terms though I'll be googling it to find out but the same personm told me that its effect may be to pull Bill closer to the shore...

Anyone else heard/ seen or have an opinion on this?
