Tropical Storm PABLO


Tropical Storm Pablo Discussion Number   3

Pablo remains a small cyclone, and recently the eye-like feature
that was noted in earlier satellite images is no longer evident.
Since the system continues to have an area of deep convection
concentrated near the center, it should still be classified as a
tropical cyclone.  The current intensity is held at 40 kt, in
general agreement with the most recent estimate from TAFB, and
pending a new scatterometer overpass.  Pablo is embedded within a
much larger cyclonic circulation that is also producing gale-force
winds well to the north and northwest of the center.

The tropical storm is moving a little south of east at around 8 kt.
A turn toward the northeast and north is expected over the next
couple of days as Pablo moves around the periphery of a large
deep-layer trough over the eastern Atlantic   The official forecast
is a little faster than the previous one but slightly slower than
the latest corrected dynamical model consensus.

Some slight strengthening is possible during the next day or so
while Pablo moves through an environment that is unstable enough to
support deep convection.  However, by 36 hours the cyclone will be
passing over waters of 18 deg C or colder.  This should result in
the system becoming an extratropical low around that time.  In 2-3
days, the global models show the post-tropical low merging with
a larger low over the north Atlantic.

Given that Pablo is embedded within a large extratropical low,
which itself is forecast to bring strong winds to the Azores, the
Portuguese Institute for the Sea and Atmosphere (IPMA) has included
the effects of this small cyclone in their products.  Those products
already account for the strong winds and high waves expected in the
