First visible images show it does not look too bad.

[Yellow Evan]

[cycloneye]

A broad area of low pressure located several hundred miles
south of Acapulco, Mexico, is producing disorganized showers and
thunderstorms. Environmental conditions appear conducive for some
slow development of this system during the next several days while
it moves westward to west-northwestward.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...30 percent.

[cycloneye]

I wonder why the global models are not so enthusiastic with this system while the intensity models are more bullish.

[Yellow Evan]

Track is way too south.

[Kingarabian]

Even if the system gains latitude, the latest CIMSS wind shear chart keeps shear very low until about 130W...

[Kingarabian]

Past couple of frames hinting at outflow trying to establish north of the system.

[cycloneye]

Low long-track riders generally get good ACE units pending conditions.

[Kingarabian]

I would up it to 50% for development:

[cycloneye]

Showers and thunderstorms associated with a broad area of low
pressure located several hundred miles south-southwest of Acapulco,
Mexico have become better organized over the past several hours.
Environmental conditions appear conducive for some additional
development of this system during the next several days while
it moves westward to west-northwestward.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...40 percent.

[Yellow Evan]

Low long-track riders generally get good ACE units pending conditions.

I doubt this turns into anything more than a weak TS or TD. Shear is just ok and this doesn't have much model support.

[Kingarabian]

28/2345 UTC 9.1N 102.5W T1.0/1.0 93E -- East Pacific

[cycloneye]

HWRF is crazy.

[Kingarabian]

I'm sure the NHC would'vet went much higher if there was GFS/Euro support.



Rare to see an invest with a convective signature well defined like this one only @ 20%.

Here is the crazy HWRF.

The National Hurricane Center is issuing advisories on Tropical
Depression Gilma, located about 1300 miles east of Hilo, Hawaii.

1. Showers and thunderstorms associated with a broad area of low
pressure located several hundred miles south-southwest of Acapulco,
Mexico continue to show signs of organization. Environmental
conditions appear conducive for some additional development of this
system during the next several days while it moves westward to
west-northwestward.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...40 percent.

Forecaster Beven

Convection is becoming a little more organized near broad low
pressure centered west of the offshore waters of Central America
near 09N102W. The estimated sea level pressure is 1010 mb. While
there has been steady development of this system over the past 12
to 18 hours, there remains some uncertainty about its development
over the next couple of days. There is a moderate chance for
tropical cyclone development through the next five days. At any
rate, large clusters of showers and thunderstorms are ongoing
within 180 nm mainly in the northwest semcircle of the low
pressure. Expect fresh to occasionally strong winds in this
convection, with seas building to 8 ft through the next two to
three days.
