Hurricane Sandy

Recommended Posts

Rather large shift

My feeling looking at the last few days is that there is going to be a continued adjustment NE. To what degree? Who knows... NCEP full diagnostic

...HURRICANE SANDY...

BASED ON THE NAM/ECMWF BNDRY LAYER WIND ANALYSES... THE MODELS

HAVE INITIALIZED SANDY ABOUT 20 NM E OF THE OBSERVED 12Z POSN OF

28.8N 76.8W. THEIR CNTRL PRESSURES ARE ABOUT 10 MB HIGHER THAN

OBSERVED. THE GFS BNDRY LAYER WIND ANALYSIS COMPARES BETTER TO

OBSERVED POSN... THOUGH THE GFS CNTRL PRES IS 10-15 MB HIGHER THAN

OBSERVED.

THE NAM BRIEFLY RETURNS TO THE 15Z NHC TRACK DURING THE DAY SUN

AND THEN TRACKS THE SYSTEM FARTHER NWD THAN THE OFFICIAL TRACK

INTO MON NIGHT. FROM MON NIGHT THRU TUE THE NAM BRINGS THE SFC

LOW ASSOC WITH THE POST-TROPICAL/EXTRATROPICAL EVOLUTION OF SANDY

FARTHER WWD THAN MOST OTHER GUIDANCE OR NHC TRACK. THE NAM MID

LVL SYSTEM COMPARES SOMEWHAT BETTER TO CURRENT CLUSTERING BY THAT

PART OF THE FCST. THE GFS STRAYS TO THE NE/N OF THE OFFICIAL

TRACK F36-60 LATE SUN-LATE MON... CURLING A LITTLE TO THE W/S BY

TUE. BY F84 LATE TUE THE GFS CLOSED LOW ALOFT IS A LITTLE SEWD OF

THE NAM. FOR MOST OF THE LAST 2 DAYS OF THE FCST THE GFS IS ON

THE STRONGER SIDE OF THE SPREAD WITH THE SYSTEM. THE UKMET IS ONE

OTHER SOLN ABOUT AS STG AT THE SFC IN SPITE OF BEING WEAKER ALOFT.

THE UKMET TRACES A WIDER ARC THAN CONSENSUS/OFFICIAL TRACK FROM

SUN ONWARD AS DOES THE CANADIAN REG GEM THRU F48 EARLY MON. THE

CANADIAN GLBL SHOWS A TRACK INCREASINGLY TO THE RIGHT OF OFFICIAL

FCST... NOT FAR FROM BEING A FASTER/SLIGHTLY SWD VERSION OF THE

UKMET. THE ECMWF DRIFTS SOMEWHAT RIGHT OF THE NHC TRACK SUN-MON

BEFORE TRENDING BACK TOWARD THAT TRACK BY F72-84 TUE. CONSULT

LATEST NHC ADVISORIES/DISCUSSIONS FOR FURTHER INFO REGARDING SANDY.

Am I the only person from sne that would have real surge issues and be evacuated?

im in short beach branford..the water from irene came close last time im at 9 feet so im very concerned about flooding also have the tidal marsh behind me where the east haven trolly tracks are so i can be cut off if it goes 12 feet im in trouble.

When I read the model interpretation during the middle of model run it's always like I'm looking at a different model. I hear how the euro has trended n and then look and see a very slight difference with the model almost the same landfall as the srn gfs that some folks were saying was by itself even though gefs ens mean was also in the same place.

From Mike

I've been working on this yesterday and today, and I'm pleased to announce

the release of a temporary sector just for Sandy as it makes landfall in

the northeast. It's a minimal selection of products that are zoomed in

slightly and a bit easier to read than some of the other images that we

offer. It's running for both the NAM and GFS, and both models offer a

Total Precip Accumulation product so we can more easily see the rainfall

impact. This sector will be removed once its usefulness has expired.

The landfall point wasn't the issue as much as how it got there.

It's a 100 mile move NE from the same time period at the 0z. That's huge. When the southern outlier comes north that much in one run - and still at 60-70 hours and with any potential adjustment in escape/speed ENE before the swing being amplified later - not sure what people are looking at. It's like people want to pick and choose model run/hours.

Not calling you narrow minded. But when someone suggests a model solution isn't meteorologically sound, usually some reasoning follows

yeah, the funny thing is I accidentally hit reply before I wanted to and just said ah f it.

What I was going say is that it takes time for the internal processes of the cyclone engine to convert - if we look at other examples of warm seclusions, its a long process. Initially the warmer cord of Sandy would resist moving the cyclone across the faster flow part of the geoptential gradient, too. It's like the left solutions are processing the cyclone like it is already converted.

It's going to be fascinating to now cast this.

That is very funny---now, We'lll see come Wednesday if he's laughing though.

I just got a robocall from WMECO (Western Mass Electric) about storm preparations/what to do, etc.). Never got one of those before.

Why would I be laughing facing this storm at my location? I find it strange this close in to even joke about stuff like that...this is serious its not snow.
