Re: EPAC: INVEST 97E
Already up to 20%/50%
A broad low pressure area located about 500 miles south-southwest of
Manzanillo, Mexico, continues to show signs of organization. Some
gradual development of this disturbance is possible during the next
several days while the system moves west-northwestward to
northwestward.
* Formation chance through 48 hours...low...20 percent
* Formation chance through 5 days...medium...50 percent

Not seeing this do much to be honest. MJO is in the dead circle and there hasn't been that much model support.

Re: EPAC: INVEST 97E

An area of low pressure, located about 430 miles south-southwest of
Manzanillo, Mexico, is producing disorganized showers and
thunderstorms. Upper-level winds are marginally conducive for some
slow development of this system during the next few days while it
moves generally northwestward.

Re: EPAC: INVEST 97E
The circulation looks fairly good IMO, but it's displaced to the east of the associated convection.

Just need convection to build and maintain itself over the LLC and we'll either have a TD or a TS.

As it moves WNW towards lesser shear values, waters are to be very very warm and the environment will be moist.

Re: EPAC: INVEST 97E
Up to 60%/70% and a change in the wording which actually calls for better conditions to come.
A well-defined low pressure system located about 350 miles southwest
of Manzanillo, Mexico, is producing limited shower and thunderstorm
activity. Although strong upper-level winds are currently inhibiting
tropical cyclone formation, these winds are forecast to decrease
by the weekend. The generally more conducive environment is likely
to result in the formation of a tropical depression during the next
day or two while this system moves generally northwestward.

NHC is being very aggressive with this system, LLC is still naked, and I don't see a break in the NE shear. IMO.

For the eastern North Pacific...east of 140 degrees west longitude:
1. Showers and thunderstorms associated with a well-defined low
pressure system located about 360 miles west-southwest of
Manzanillo, Mexico, continue to show signs of organization.
Upper-level wind conditions continue to improve, and a tropical
depression is likely to form tonight or Friday while this system
moves generally northwestward.
