Not to detract from Dorian, but this just formed off Africa.

1. A broad area of low pressure associated with a tropical wave is
located just south of the Cabo Verde Islands. This system has become
better organized since yesterday, and environmental conditions
appear conducive for additional development during the next several
days. A tropical depression is likely to form by the middle of the
week while the system moves generally northwestward across the
eastern tropical Atlantic Ocean. Heavy rainfall is possible over
portions of the southern Cabo Verde Islands during the next couple
of days, and interests on those islands should monitor the progress
of this system.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.

A broad area of low pressure centered near the Cabo Verde Islands is
producing a large area of showers and thunderstorms. This system is
showing signs of becoming better organized, and environmental
conditions appear conducive for additional development during the
next several days. A tropical depression is likely to form by the
middle of the week while the system moves generally northwestward
across the eastern tropical Atlantic Ocean. Heavy rainfall is
possible over portions of the southern Cabo Verde Islands during the
next day or so, and interests on those islands should monitor the
progress of this system.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...70 percent.
Now up to 60/70.

An area of low pressure located about 100 miles west-southwest of
the Cabo Verde Islands is producing a large area of showers and
thunderstorms. This system is gradually becoming better organized,
and environmental conditions appear conducive for additional
development during the next several days. A tropical depression is
likely to form by the middle of the week while the system moves
generally northwestward across the eastern tropical Atlantic Ocean.
Heavy rainfall is possible over portions of the southern Cabo Verde
Islands during the next day or two, and interests on those islands
should monitor the progress of this system.
* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...high...80 percent.

80/80 chances of development with this one now.

Recent satellite-derived surface wind data indicate that the low
pressure system located about 150 miles west-southwest of the Cabo
Verde Islands has become better defined. Shower and thunderstorm
activity is beginning to show signs of organization, and
environmental conditions appear conducive for a tropical depression
to form during the next day or so
while the system moves generally
northwestward across the eastern tropical Atlantic Ocean
. Locally
heavy rainfall will be possible over the Cabo Verde Islands through
Tuesday.

* Formation chance through 48 hours...high...80 percent.

* Formation chance through 5 days...high...80 percent.

Recent satellite-derived wind data indicate that an elongated area
of low pressure located a few hundred miles west of the Cabo Verde
Islands has become better defined since yesterday. Although this
system is currently producing limited showers and thunderstorms, a
tropical depression is expected to form during the next day or so
while the system moves generally northwestward across the eastern
tropical Atlantic Ocean.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

Up to 90/90 odds. Should have something later today.

Recent satellite-derived surface winds indicate that the low
pressure area located a few hundred miles west of the Cabo Verde
Islands is becoming better defined. Associated thunderstorm

activity has been increasing and showing signs of organization, and
a tropical depression is expected to form later today while the
system moves generally northwestward across the eastern tropical
Atlantic Ocean.


* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

An area of low pressure located a few hundred miles west of the Cabo
Verde Islands continues to exhibit a broad circulation. Any
significant increase in thunderstorms would contribute to the
formation of a tropical depression.

NHC giving Gabrielle a 80% chance at a comeback.

An area of low pressure, the remnants of Gabrielle, is producing
an area of showers and thunderstorms to the north of its center.
Although upper-level winds are not particularly favorable for
re-development of this system at this time, conditions are expected
to become increasingly conducive for regeneration, and the low is
likely to become a tropical storm again within the next day or so.

* Formation chance through 48 hours...high...80 percent.

* Formation chance through 5 days...high...80 percent.
