Might as well start the thread since it's up to 0/40.

1. A broad low pressure area centered near the northeastern coasts of
Nicaragua and Honduras is producing an extensive area of
disorganized clouds and thunderstorms over the central and western
Caribbean Sea, as well as portions of Central America. While
surface pressures are relatively low in the area, upper-level winds
are currently not favorable for tropical cyclone formation.
Environmental conditions could become less hostile by late this
weekend or early next week, and a tropical depression could form as
the system moves slowly northwestward across the northwestern
Caribbean Sea and the southern Gulf of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...medium...40 percent.

Yep all models have something now, so looking more and more likely...
 
What does "environmental conditions become less hostile" mean?
I.e. if its less shear, what is changing to cause that to happen? Movement of the high? Thanks so much! :):D:rolleyes:
 
I found 19 TCs on record since 1851 during El Nino that had genesis 10/1-10 either in the W Caribbean or the GOM. Of those, 11 landfalled in FL with 6 of those hitting in/near the Big Bend though none have done so since 1900, 1 hitting Tampa area, 3 hitting Ft. Myers area, and 1 hitting the S tip. Another 2 hit LA and 1 hit the TX/LA border. So, 14 of 19 hit the CONUS. Regarding the other 5, 3 hit the Bahamas or Turks and Caicos, 1 hit MX, and 1 died in the W Caribbean.
13 of the 19 were during weak Nino, 3 during moderate Nino, and 3 during strong Nino. So, of all during El Nino, they've been more common during weak ones similar to what we're in now.


**Edit for pcbjr and others to make feel somewhat better: Of the 14 that hit the CONUS, only 5 hit as a H (good news). I assume this is partially due to there being shear inducing El Nino in some of these cases.
Edit 2: But the bad news is that SSTs are above normal much of the GOM..so more fuel.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Thu Oct 4 2018

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Leslie, located over the central Atlantic Ocean.

1. Surface observations and satellite data indicate that an area of low
pressure is located near Cabo Gracias a Dios on the eastern border
of Honduras and Nicaragua. This system is accompanied by an
extensive area of disturbed weather extending from Central America
eastward through Hispaniola. Upper-level winds are not currently
favorable for tropical cyclone formation, but environmental
conditions are forecast to become less hostile and a tropical
depression could form by late this weekend or early next week in the
northwestern Caribbean Sea or the southern Gulf of Mexico as the
system moves slowly northwestward. Regardless of tropical cyclone
formation, this disturbance will continue to bring torrential rains
primarily to portions of Central America and the Yucatan peninsula
during the next few days.
* Formation chance through 48 hours...low...near 10 percent.
* Formation chance through 5 days...medium...50 percent.
 
We have 97E in the pacific close by so probably gotta wait til that moves out.

FWIW, which ain't much in the long range.
 
0Z UKMET FL panhandle into SE AL and then west central GA: way right of 24 hours ago; nearly identical to 0Z CMC;
pressure at hour 144 of 979 mb looks funky since that's well inland

An area of low pressure located near Cabo Gracias a Dios on the
eastern border of Honduras and Nicaragua is accompanied by an
extensive area of disturbed weather extending from Central America
eastward across Hispaniola. Although strong winds aloft are located
just to the north of this system, the upper-level environment is
expected to be conducive enough to allow for some development, and a
tropical depression could form by late this weekend or early next
week over the northwestern Caribbean Sea or southern Gulf of Mexico
while the system moves slowly northwestward. Regardless of tropical
cyclone formation, this disturbance will continue to bring
torrential rains primarily to portions of Central America and the
Yucatan peninsula during the next few days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.
