Nice structure so far, but heading change will hurt it in 48 hours.

GEFS looks like it wants a hurricane. Not so sure if I trust this, given the lack of support for this intensity from other modeling, and the rollercoaster nature of oper-GFS intensity forecasting for this disturbance.

We should see Frank out of this but I'm not very confident in this one becoming anything significant.

I am in no way a professional. Take what I say with a grain of salt as I could be totally wrong. Please refer to the NHC, NWS, or SPC for official information.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Sun Jul 24 2022

For the eastern North Pacific...east of 140 degrees west longitude:

1. Offshore of Southern Mexico:
Shower activity is starting to show signs of organization associated
with a tropical wave located a couple of hundred miles south off the
coast of southern Mexico. Environmental conditions appear conducive
for further development, and this system is likely to become a
tropical depression in the next few days. This system is forecast to
move generally westward at 10 to 15 mph, remaining well south of the
coast of southern and southwestern Mexico during the next several
days.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...80 percent.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 AM PDT Mon Jul 25 2022

For the eastern North Pacific...east of 140 degrees west longitude:

1. Offshore of Southern Mexico:
Shower and thunderstorm activity has increased this morning in
association with a broad area of low pressure located a few hundred
miles south of the coast of southern Mexico. Environmental
conditions appear conducive for additional development, and this
system is likely to become a tropical depression in the next day
or two. This low pressure area is forecast to move generally
westward at 10 to 15 mph, remaining well south of the coast of
southern and southwestern Mexico during the next several days.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

Offshore of Southern Mexico:
Shower and thunderstorm activity is showing signs of organization in
association with an area of low pressure located a few hundred miles
south of the coast of southern Mexico. Recent satellite-derived wind
data also indicates the circulation is gradually becoming better
defined. Environmental conditions appear conducive for additional
development, and this system is expected to become a tropical
depression over the next day or so. This low pressure area is
forecast to move generally westward at 10 to 15 mph, remaining well
south of the coast of southern and southwestern Mexico during the
next several days.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.

HWRF bombs it like usual :lol: 959mb at the end of the run. HMON down to 967mb at the end of the run. GFS keeps it pretty weak.

I'm still leaning towards the weaker solutions for now, but maybe it can get going quickly and prove me wrong
