Convection has balled up nicely now and the circulation appears a bit tighter. It's not perfect, but if this was a recon storm I'm betting they would find a tropical storm with 40-45kt winds.
What model showed this, or at least something like it, first? I'd say it was a win for that model.

Looking good, almost seems like it has a closed circulation now.

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
640 PM PDT Fri Apr 24 2020

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

Special Outlook issued to update discussion on the low pressure area
located well south-southwest of Baja California Sur.

Showers and thunderstorms associated with a broad area of low
pressure located about 800 miles south-southwest of the southern
tip of Baja California Sur have changed little in organization
today. Environmental conditions are forecast to be conducive for
further development, and a tropical depression is likely to form
during the next day or so while the system moves northwestward at
around 10 mph. By Sunday, upper-level winds should become
unfavorable for development. The next Special Tropical Weather
Outlook on this system will be issued by 8 AM PDT Saturday, or
earlier, if necessary.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...80 percent.

Tropical Depression One-E Discussion Number 1
NWS National Hurricane Center Miami FL EP012020
800 AM PDT Sat Apr 25 2020

Overnight ASCAT data showed the disturbance over the central eastern
Pacific basin has developed a well-defined center. Furthermore,
convection associated with the low has increased in organization
since yesterday. Advisories have therefore been initiated on
Tropical Depression One-E. The initial intensity is set at 30 kt
based primarily on the aforementioned ASCAT data. This marks
the earliest formation of a tropical cyclone in the eastern North
Pacific basin since the satellite era began in 1966.

The depression is not expected to stick around for long. Dry air in
the surrounding environment appears to have already wrapped around
much of the cyclone's circulation, and this is likely limiting its
associated convection. This should also prevent the depression from
strengthening much during the next 24 h, but it can not be ruled out
that the system could briefly become a tropical storm later today.
On Sunday, an increase in vertical wind shear and lower SSTs along
the forecast track will contribute to the depression's demise, and
it is expected to become a remnant low within about 36 h, if not
sooner.

The initial motion estimate is northwest at 6 kt. The depression
should continue on a general northwestward heading for another day
or so until it becomes a remnant low. The remnants should then turn
westward with the low-level trade wind flow until it dissipates
entirely in a couple of days.


FORECAST POSITIONS AND MAX WINDS

INIT 25/1500Z 14.1N 116.1W 30 KT 35 MPH
12H 26/0000Z 14.9N 116.8W 30 KT 35 MPH
24H 26/1200Z 15.9N 118.1W 30 KT 35 MPH
36H 27/0000Z 16.7N 119.8W 25 KT 30 MPH...POST-TROP/REMNT LOW
48H 27/1200Z 17.1N 121.7W 25 KT 30 MPH...POST-TROP/REMNT LOW
72H 28/1200Z...DISSIPATED

She did it. The mad lad actually did it. We have an EPac cyclone in April, 20 days before the season starts.

Eat your heart out, Adrian ‘17.

Though it looks at the moment it will likely remain a Tropical Depression.

True, but impressive nonetheless. Last year, the first system didn’t form until the very end of June.
