==discussion==
Hurricane Sandy has been moving northward through the Northwestern
Bahamas today with winds in excess of 120 km/h. During the weekend
Sandy is forecast to continue to track north or northeastward while
remaining at or near hurricane strength. Sandy will gradually lose
some of its tropical characteristics during the next few days.
On Monday Sandy is expected to take a turn to the northwest toward
the United States East Coast. Current indications are that Sandy
will move inland on the United States East Coast on Tuesday as a very
large and powerful storm. There are various factors influencing the
evolution of the storm. As a result there is still a relatively high
degree of uncertainty in the impacts of the storm.
Based on the current forecast scenario, Southern and Eastern Ontario
are likely to see the most rainfall from this system. These areas
will likely also be subject to strong and gusty winds as will
Southern Quebec and the Maritimes. Although it is too early to nail
down any specific values, people living in these areas are urged to
pay close attention to messages from the Canadian Hurricane Centre
and local weather forecasts and possible future warnings throughout
the weekend.

latest:
- forecast position, central pressure table.
- strength and predicted wind radii table.
- hurricane track information map.

Please also refer to the public and marine forecasts and warnings
issued by Environment Canada for your area.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
343 PM EDT FRI OCT 26 2012
.SYNOPSIS...
HIGH PRESSURE WILL REMAIN ACROSS THE REGION THROUGH SATURDAY.
ON SUNDAY SANDY WILL BEGIN TO MOVE UP THE EASTERN SEABOARD AND
WILL LIKELY AFFECT THE REGION EARLY NEXT WEEK.
&&.....
.....LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
-- Changed Discussion --
MODELS CONTINUE TO FLUCTUATE ON TRACK OF SANDY...WITH THE LATEST
TREND IN FORECAST GUIDANCE SHOWING A SLIGHTLY MORE NORTHERLY PATH
BUT STILL SOUTH OF THE GULF OF MAINE. USED A BLEND OF THE 12Z GEM
GLOBAL AND THE GFS FOR THE WIND FORECAST AND MANUALLY MADE SOME
ADJUSTMENTS UPWARD TO ACCOUNT FOR THE GEM`S LOW BIAS. IT SHOULD
BE NOTED THAT THE STORM IS STILL AT LEAST THREE DAYS AWAY FROM
LANDFALL AND THAT FURTHER FLUCTUATIONS IN THE TRACK WILL BE
POSSIBLE.
IN TERMS OF IMPACTS, IT IS LOOKING LIKE A LATE MONDAY NIGHT/EARLY
TUESDAY MORNING LANDFALL. NORTHERN AND EASTERN MAINE CONTINUE TO BE
ON THE NORTHERN PERIPHERY OF THE SYSTEM. BUT CONSIDERING HOW BROAD
THE SYSTEM IS EXPECTED TO BECOME...SIGNIFICANT WINDS ARE LIKELY
ACROSS SOUTHERN AND COASTAL MAINE. ALONG SHORE WINDS EXPECTED TO
INCREASE TO 30-35 MPH AND HIGHER GUSTS ON MONDAY. WINDS WILL
CONTINUE TO INCREASE MONDAY NIGHT INTO TUESDAY...AS SANDY
TRANSITIONS AWAY FROM TROPICAL CHARACTERISTICS TO EXTRA-TROPICAL.
HIGHEST WINDS FOR COASTAL AREAS WILL LIKELY OCCUR MONDAY NIGHT INTO
THE FIRST PART OF TUESDAY DURING WHICH TIME SUSTAINED WINDS TO 40
MPH WITH HIGHER GUSTS WILL BE POSSIBLE. THIS MAY LEAD TO POWER
OUTAGES AND WILL ALSO LEAD TO STORM SURGE AND POSSIBLE COASTAL
FLOODING/EROSION.
RAIN, HEAVY AT TIMES, WILL ALSO OVERSPREAD THE AREA MONDAY NIGHT
AND CONTINUE TUESDAY. 1 TO 3 INCHES OF RAIN WITH LOCALLY HIGHER
AMOUNTS ARE LIKELY BY TUESDAY EVENING. BEYOND THIS TIME, SANDY
LOOKS TO BE VERY SLOW MOVING AS IT BECOMES CAPTURED UNDER AN UPPER
LEVEL LOW. AS THE STORM GRADUALLY WEAKENS WINDS WILL DIMINISH
THROUGH WEDNESDAY AND THURSDAY WITH PERIODS OF RAIN AND SHOWERS
CONTINUING HOWEVER.

HURRICANE SANDY DISCUSSION NUMBER 18
NWS NATIONAL HURRICANE CENTER MIAMI FL AL182012
500 PM EDT FRI OCT 26 2012
THE LOW-LEVEL CENTER OF SANDY REMAINS EXPOSED TO THE SOUTH OF THE
MAIN AREA OF DEEP CONVECTION AS STRONG SHEAR CONTINUES TO INFLUENCE
THE SYSTEM. THE LAST RECONNAISSANCE MISSION INTO THE TROPICAL
CYCLONE SUGGESTED THAT THE INTENSITY MAY BE DROPPING BELOW
HURRICANE STATUS. THE CURRENT WIND SPEED IS HELD AT 65 KT PENDING
THE NEXT AIR FORCE HURRICANE HUNTER MISSION SCHEDULED FOR A 0000
UTC CENTER FIX. THE SHIPS OUTPUT INDICATES THAT THE SHEAR WILL
REMAIN QUITE STRONG FOR THE NEXT DAY OR SO...AND THEREFORE THE NHC
FORECAST INDICATES WEAKENING FOR THE NEXT 36 HOURS OR SO.
THEREAFTER...THE GLOBAL MODELS SHOW DEEPENING OF THE CYCLONE
PRESUMABLE DUE TO BAROCLINIC FORCING. THIS IS ALSO INDICATED IN
THE OFFICIAL INTENSITY FOREACST. THE GLOBAL MODELS ALSO SUGGEST
THAT SANDY COULD TRANSITION INTO A FULLY EXTRATROPICAL CYCLONE IN 3
TO 4 DAYS.
THE MOTION CONTINUES TO BE RATHER SLOW AND...IN FACT...RECENT
VISIBLE IMAGES SUGGEST LITTLE SHORT-TERM MOVEMENT OF THE CENTER.
HOWEVER A MORE REPRESENTATIVE ESTIMATE OF THE MOTION IS NEAR 360/6.
AFTER SANDY ESCAPES THE INFLUENCE OF A MID- TO UPPER-LEVEL LOW TO
ITS WEST...THE CYCLONE SHOULD MOVE NORTH-NORTHEASTWARD TO
NORTHEASTWARD WITH SOME INCREASE IN FORWARD SPEED. BY AROUND 72
HOURS...A NEGATIVELY-TILTED SHORTWAVE TROUGH NEAR THE U.S. EAST
COAST AND A RIDGE OVER EXTREME EASTERN CANADA SHOULD CAUSE SANDY TO
TURN TOWARD THE NORTHWEST AND WEST-NORTHWEST TOWARD AND OVER THE
U.S. COAST. INTERESTS ARE REMINDED NOT TO FOCUS ON THE EXACT TRACK
OF THIS SYSTEM SINCE SIGNIFICANT IMPACTS WILL EXTEND WELL AWAY FROM
THE LOCATION OF THE CENTER.
