National Hurricane Center and HPC Not Messing Around

Wow, VERY bold. The National Hurricane Center just put this out with their 11am update:



PRELIMINARY EXTENDED FORECAST DISCUSSION
NWS HYDROMETEOROLOGICAL PREDICTION CENTER COLLEGE PARK MD
942 AM EDT THU OCT 25 2012

VALID 12Z MON OCT 29 2012 - 12Z THU NOV 01 2012


...HIGH IMPACT MERGING OF ENERGETIC SYSTEMS ANTICIPATED OFF THE
MID ATLANTIC COAST...


PRELIMINARY UPDATE...

DESPITE A MODEST CLUSTER OF OUTLYING DETERMINISTIC SOLUTIONS AND
ENSEMBLE MEMBERS FROM THE VARIOUS MODELING CENTERS, THE LION'S
SHARE OF GUIDANCE INDICATES THAT THE CIRCULATION ASSOCIATED WITH
HURRICANE SANDY WILL PASS CLOSE ENOUGH TO THE AMPLIFYING POLAR
TROUGH OVER THE EASTERN UNITED STATES TO BECOME INCORPORATED INTO
A HYBRID VORTEX OVER THE MID ATLANTIC AND NORTHEAST NEXT TUESDAY.

THE HIGH DEGREE OF BLOCKING FROM EASTERN NORTH AMERICA ACROSS THE
ENTIRE ATLANTIC BASIN IS EXPECTED TO ALLOW THIS UNUSUAL MERGER TO
TAKE PLACE, AND ONCE THE COMBINED GYRE MATERIALIZES, IT SHOULD
SETTLE BACK TOWARD THE INTERIOR NORTHEAST THROUGH HALLOWEEN,
INVITING PERHAPS A GHOULISH NICKNAME FOR THE CYCLONE ALONG THE
LINES OF "FRANKENSTORM", AN ALLUSION TO MARY SHELLEY'S GOTHIC
CREATURE OF SYNTHESIZED ELEMENTS.
