Seeing some popcorn convection near the circulation. Maybe it can gather itself now in the next 6 hours.

I still see it is still attached to the ITCZ, is going to have to gain some latitude if it wants to do something.

SHIPS doesn't do that good of a job in the short term with invests, especially invests with mid-level shear.

For the eastern North Pacific...east of 140 degrees west longitude:
1. A broad but well-defined area of low pressure is located about 975
miles south-southwest of the southern tip of the Baja California
peninsula. Even though shower and thunderstorm activity remains
minimal and disorganized at this time, a tropical depression could
still form during the next few days as the low moves west-

Convection has increased this morning but broad COC is to the NE of the convection. Chances have definitely gone down for 91E.

1. Showers and thunderstorms associated with an area of low pressure
located about 975 miles south-southwest of the southern tip of the
Baja California peninsula have increased since yesterday.
Environmental conditions appear generally conducive for development,
and a tropical depression could form during the next few days while
the low moves west-northwestward.
* Formation chance through 48 hours...medium...50 percent
* Formation chance through 5 days...medium...60 percent

Re: EPAC: INVEST 91E
Thunderstorm activity has increased, and while mid-level shear causes by a displaced anti-cyclone is forecast to pick up, this shear should relax again as suggested by the SHIPS output and current CMISS graphics. Poleword outflow should eventually increase as this system rounds a ridge in 2-4 days, opening the door for the further development, as support mostly by the GFS, who seems to be handling this system the best for a change.

Re: EPAC: INVEST 91E
Circulation remains broad and elongated SW-NE with most of the convection on the southern quadrant, looking at the vis satellite loop as if there's drier stable air moving into the invest from the north.

Looks like outflow is becoming established to the north.

Re: EPAC: INVEST 91E
Seems to be making progress. Mid-level shear seems to be declining for now at least and poleword outflow is increasing, although the GFS and ECMWF don't show much further progress.

Re: EPAC: INVEST 91E
Still think on the 1-2nd this was a TD before intermittently losing and regaining intensity.
