No real consensus on intensity right now on this run.GFS is the only one that goes to Hurricane.

I'm looking at 91E for the first time, to me it looks nothing more than a low pressure attached to the ITCZ, we all know things take longer to get going in this case, so I don't expect anything out of this over the next 48 hrs if not longer.

12 ECMWF keeps this weak and broad and eventually fizzles this out. 12z EPS Ensembles show the same. 12z HWRF doesn't do much with this, but the run didn't seem well-initialized and the GFDL is in the same camp of the ECMWF intensity-wise.

Track wise, the models are in good agreement, however. 91E will continue west before briefly moving north due to a trough but rather than re-curving, gets blocked and turns back to the west.

30%-80%.

TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
500 PM PDT TUE MAY 31 2016

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

An elongated area of low pressure located about 1000 miles south of
the southern tip of the Baja California peninsula is producing a
large area of disorganized cloudiness and showers. Environmental
conditions are expected to be conducive for slow development of
this system during the next several days, and a tropical
depression is likely to form later this week as the disturbance
moves slowly west-northwestward.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...high...80 percent

The 00z intensity models are more bullish than in past runs.

Seems the GFS upgrade hasn't changed a thing as far as the model bombing out systems in the medium to long-range. No other model is showing anything close to what the GFS is showing, even the usual bullish CMC.

I don't think a hurricane is out of the question.

An anti-cyclone is building over the system and shear ahead of the system in the short and medium range is weak-moderate:

SST's are plenty warm:

CMC is seldom bullish in the EPAC; it usually shows a bunch of weak systems interacting with each other. It likely won't get as strong as the GFS is showing, but a minimal hurricane is not out of the question. EPAC storms have a tendency to greatly outdue expectations, but given the erratic nature of low latitude storms that 91E is in, I expect this to take its sweet time.

00z GFS flips weaker. Wouldn't be surprised if the 06z is a cane' again.

I would believe this will be a tropical storm but no stronger based on model consensus

I agree... streamline analysis has 91E tucked firmly into the ITCZ. Until that changes, development will be slow to occur. As it gains that latitude in a few days, that will boost those chances at development, in concert of what the NHC is currently saying.

conducive for additional development of this system during the next
several days, and a tropical depression is likely to form later this
week as the disturbance moves west-northwestward at about 15 mph.
* Formation chance through 48 hours...medium...50 percent
* Formation chance through 5 days...high...90 percent
