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.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 AM PDT Thu Oct 21 2021

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

Disorganized showers and thunderstorms within a few hundred miles of
the southern coast of Mexico are associated with a broad area of
low pressure located just to the southwest of the Gulf of
Tehuantepec. Environmental conditions are expected to be
conducive for gradual development of this system during the next
several days, and a tropical depression is likely to form by this
weekend while the system moves slowly west-northwestward to
northwestward near or just offshore the southern coast of Mexico.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...90 percent.

18z GFS has development starting in 12 hours and a steady spin up.

Looking at visible satellite imagery, development might be starting right now. Convection has been quite consistent over where I think the LLC is trying to form.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
500 PM PDT Thu Oct 21 2021

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

1. Shower activity associated with a low pressure area located a few
hundred miles southwest of the Gulf of Tehuantepec has become better
organized during the last 24 hours. Environmental conditions are
expected to be conducive for additional development of this system
during the next several days, and a tropical depression is likely to
form during the next couple of days while the system moves slowly
west-northwestward to northwestward near or just offshore the
southern coast of Mexico.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.

This has definitely organized throughout the day but not sure there’s a closed surface circulation.

just what we always wanted for day of the dead.. showers and a blow dry.. i am hoping mazatlan is not bullseye this time, but friends live under jalisco and some other wonderful potential bullseyes here.. all on boats yes. folks are returning from summer away to their poor lonely boats and other friends in san blas mx are hunkering for this potential.
summer does wish to make its exit as a lion doesnt it... may the storm be gorgeous and damages minimal.

Looks really good. Could get classified at 500 edt. Distinct spiraling is occurring with deep convection. Might be a tc already.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
1100 PM PDT Thu Oct 21 2021

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

Showers and thunderstorms associated with a low pressure area
located about 250 miles south of Acapulco, Mexico, continue to show
signs of organization, but recent satellite wind data indicate that
the low does not yet have a closed surface wind circulation.
Environmental conditions are expected to be conducive for additional
development, and a tropical depression or tropical storm is expected
to form over the next day or so while moving slowly
west-northwestward or northwestward just offshore the southern coast
of Mexico. Interests along the southern and southwestern coast of
Mexico should monitor the progress of this system during the next
few days, and additional information, including gale warnings, can
be found in High Seas Forecasts issued by the National Weather
Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...90 percent.

&&

High Seas Forecasts issued by the National Weather Service can be
found under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on
the web at ocean.weather.gov/shtml/NFDHSFEPI.php
