Hurricane Epsilon
Jamais Cascio, 4 Dec 05

IR image of atlantic weatherAs most of you know, this year's Atlantic hurricane season, which just ended officially (even if the Atlantic hurricanes haven't noticed), was the most active on record. What you might not have heard, however, is that all National Weather Service predictions were for Epsilon to weaken instead of getting stronger. This year's hurricane season wasn't just stronger and more active than anyone expected, it was also weirder.

This point is driven home by the latest update on Epsilon published by the National Hurricane Center at NOAA. I've reproduced the discussion here in its entirety:

HURRICANE EPSILON DISCUSSION NUMBER  21
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
10 AM EST SUN DEC 04 2005

AFTER A SLIGHT WEAKENING OVERNIGHT...MORNING SATELLITE IMAGES
INDICATE THAT EPSILON HAS RESTRENGTHENED. THE EYE HAS BECOME MORE
SYMMETRIC AND THE RING OF CONVECTION IS STRONGER THAN YESTERDAY.
T-NUMBERS FROM TAFB AND SAB ARE 4.5 ON THE DVORAK SCALE AND ON THIS
BASIS...THE INITIAL INTENSITY IS INCREASED TO 75 KNOTS. THERE ARE
NO CLEAR REASONS...AND I AM NOT GOING TO MAKE ONE UP...TO EXPLAIN
THE RECENT STRENGTHENING OF EPSILON AND I AM JUST DESCRIBING THE
FACTS. HOWEVER...I STILL HAVE TO MAKE AN INTENSITY FORECAST AND THE
BEST BET AT THIS TIME IS TO PREDICT WEAKENING DUE TO COLD WATER
...HIGH SHEAR AND DRY AIR.

EPSILON IS MOVING EASTWARD AT 10 KNOTS...RUNNING AHEAD OF A STRONG
MID-LATITUDE TROUGH. BUT SOON...ACCORDING TO THE GLOBAL
MODELS...THE CYCLONE WILL BE TRAPPED SOUTH OF A DEVELOPING RIDGE
WHICH EVENTUALLY FORCE EPSILON SOUTHWARD AND THEN SOUTHWESTWARD.
THERE IS FAIRLY GOOD GUIDANCE AGREEMENT IN SHOWING THIS MOTION.
ALTHOUGH EPSILON WILL ENCOUNTER WARMER WATERS ONCE IT MOVES TOWARD
THE SOUTHWEST. HOWEVER...THE UPPER LEVEL WINDS ARE EXPECTED TO BE
HIGHLY UNFAVORABLE AND EPSILON WILL LIKELY BECOME A REMNANT LOW. I
HEARD THAT BEFORE ABOUT EPSILON...HAVEN'T YOU?

FORECASTER AVILA

When the forecasters at the National Hurricane Center are visibly disturbed by the progress of a storm, you know things have gotten bad.

Definitely a wacky storm ... but also most definitely not another Category FIve.

"What you might have heard is that the latest hurricane, Epsilon, joined the ranks of the multiple Category Five hurricanes this year;"

whoops, misread the forecast text. fixed.

Epsilon is going to get stronger as it heads west to make landfall on the US east coast. It willgo south then southwest anf finally west along the track tropical waves go over, but its already a hurricane. Batton down the hatches.

I hope Epsilon continues to defy forcaters. Just what we need.

Does anyone remember a book that was banned in the early sixties called Epsilon Rising that accuratly depicts the last five storm including Katrina and now Episolan as the precurser to some dire pridictions of the author all which have certainly come true?
