As you said,it all depends on how far it moves from the Mexican coast to then be the big one of this basin.

This has one thing going for it. It's more likely to get going much faster than 93/94E.

GFS and ECMWF runs have been pretty consistent over the last few days about 95E staying far enough off of the coast to bomb out. The GFS has been the most aggressive, being the GFS, but the Euro still produces at least a Cat 2 hurricane.

This will probably be the last notable storm in the EPac before the Atlantic takes over next week.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Cabo San Lucas will have a close call.

Look at the intensity models.

This one actually does have a pretty good satellite signature right now with some deep convection and healthy spin. I’m feeling slightly hopeful in regards to intensity. I think it might have a legitimate shot at Cat 2/3. We’ll see though, this season has been full of disappointment.

Definitely think this is the EPAC's best shot at another major out of all the storms in this outbreak. 10E is struggling, 93E probably won't amount to anything and 94E looks like it'll be a moderate TS at the very most. This will have by far the most time and the most favorable environment out of all of them, and models are clearly latching on to this.

I think this will barely muster Cat.2 and that's me being generous. Prove me wrong, EPAC.

Showers and thunderstorms associated with a trough of low pressure
located several hundred miles southeast of the Gulf of Tehuantepec
are beginning to show signs of organization. Conditions appear
conducive for further development and a tropical depression or
tropical storm is likely to form later this weekend or early next
week while the system moves generally west-northwestward just
offshore of the southwestern coast of Mexico.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

3. A low pressure system located several hundred miles southeast of the
Gulf of Tehuantepec continues to show signs of development. A broad
and elongated closed low pressure system has formed, and the
associated shower and thunderstorm activity is beginning to organize
into bands. Although recent satellite-derived wind data indicate
that the system does not yet have a well-defined center, environment
conditions appear conducive for further development. A tropical
depression or tropical storm will likely form tonight or on Sunday
while the system moves generally west-northwestward just offshore of
the southwestern coast of Mexico.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
