They have this one gaining latitude fairly quickly up into that area with the dry salmon cirrus clouds.
Hope our luck continues, all we need is an East coast trough for Karl and 96L could end the season(at least for Texas).

How would it end the season for Texas?

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
805 AM EDT SAT SEP 17 2016

A tropical wave located just offshore of the west coast of
Africa extends along 18W-19W from 10N-17N with a 1009 mb low
near 12N18W moving west 5 to 10 kt over the past 24 hours.
Wave
coincides with a global model 700 mb trough and is embedded
within a surge of moisture as shown on the Total Precipitable
water imagery. Numerous strong convection is within 30/45 nm of
a line from 12N21W to 16N17W. Scattered moderate to isolated
strong convection are from 11N13N between 18W-22W and from 13N-
18N west of 23W to just inland over Africa. Environmental
conditions appear conducive for gradual development, and a
tropical depression could form by the middle of next week.
Regardless of tropical cyclone formation, this system could
bring rain and gusty winds to portions of the Cabo Verde Islands
during the next couple of days. This system has a medium chance
of tropical formation within the next 48 hours.

Showers and thunderstorms continue near an elongated area of low
pressure located between Africa and the Cabo Verde Islands.
Environmental conditions appear conducive for development, and a
tropical depression could form by the early part of next week while
this system moves west-northwestward to northwestward across the
eastern tropical Atlantic. This system is likely to bring heavy
rain and gusty winds to portions of the Cabo Verde Islands during
the next couple of days.

Tropical Weather Discussion
NWS National Hurricane Center Miami FL
146 PM EDT SAT SEP 17 2016

Showers and thunderstorms have increased today near a broad
surface low associated with a tropical wave located between
Africa and the Cabo Verde Islands. The wave axis extends from
17N19W to a 1008 mb low near 12N19W to 10N19W. Environmental
conditions appear conducive for development, and a tropical
depression could form by the early next week while this system
moves westward to west-northwestward across the eastern tropical
Atlantic. This system is likely to bring heavy rain and gusty
winds to portions of the Cabo Verde Islands during the next couple
of days. At this time, a broad area of scattered moderate
convection prevails from 06N-18N between 17W-23W. This system has
a medium chance of tropical formation within the next 48 hours.

The cold fronts start digging further south in October, so the eastern gulf coast gets more of the storms that enter the GOM.

A broad area of low pressure located between the Cabo Verde Islands
and the west coast of Africa is producing a large, but disorganized
area of cloudiness and showers. Although this disturbance has not
become any better organized today, conditions are favorable for a
tropical depression to form by the early part of next week while
the system moves west-northwestward to northwestward across the
eastern tropical Atlantic. Regardless of development, heavy rains
and gusty winds are expected in the Cabo Verde Islands during the
next couple of days.

Up to 50%-80%

A large low pressure, located a couple of hundred miles southeast of
the Cabo Verde Islands, continues to produce a widespread area of
cloudiness and disorganized thunderstorms. Environmental conditions
are expected to be conducive for development, and a tropical
depression is likely to form by mid-week while the low moves
west-northwestward to northwestward across the eastern tropical
Atlantic. Regardless of development, locally heavy rains and strong
gusty winds are possible in the Cabo Verde Islands during the next
couple of days.

A broad area of low pressure located near the Cabo Verde Islands is
producing disorganized cloudiness and thunderstorms. Gradual
development of this system is likely, and a tropical depression
could form within the next few days before environmental conditions
become less conducive late this week. This system is expected to
move west-northwestward to northwestward over the eastern Atlantic
during the next several days. Regardless of development, locally
heavy rains and strong gusty winds are possible in the Cabo Verde
Islands during the next day or so.

This will be a fish, look at the break in the ridge around 40W in a few days but does look like it could become Larry later this week
