Convection is almost gone so Zeta's hours as a cyclone are numbered.But it has made history.

The models and the official forecast take it NWwd. Shear is stronger up there, plus the waters are colder. Zeta will probably be a remnant low in a few hours, and regeneration is unlikely unless something really freaky happens. Like everything that happened with Epsilon.
But that can't happen twice...can it?

4 PM Discussion:
Zeta consists of a very vigorous low-level circulation but the
convection appears to be rapidly vanishing. There are a few
clusters of thunderstorms within cyclonically curved bands to the
east of the center. The current satellite presentation suggests
that Zeta has continued to weaken and the best estimate of the
intensity is 45 knots. These winds are probably confined to the
north and east of the center. It seems that finally shear and
dry air are disrupting the cyclone...and a faster weakening trend
should begin soon. However...the system could linger as a remnant
low for several more days.
Now that Zeta is becoming a shallow system...it will probably be
steered by the low level flow between the subtropical high and an
approaching cold front. Zeta should then turn more to the northwest
and continue on this general track until dissipation.

ZETA ON A WEAKENING TREND...IT IS ABOUT TIME...
Above is the header that Avila wrote at the 4 PM Public Advisorie.Farewell very soon for Zeta but it made it's history and was unique.

Mark
According to what I read in this same forum, 1954 received the ACE numbers of Alice life in 1955 since the storm formed in 1954. So, I think since Zeta formed in 2005, its ACE numbers of 2006 will go toward 2005!
That is true. As a matter of fact, this morning, Zeta pushed 2005 into the lead for ACE.
