Disorganized showers and thunderstorms located several hundred
miles south-southwest of Manzanillo, Mexico, are associated with a
tropical wave. Environmental conditions appear conducive for the
development of a tropical depression by early next week while the
system moves westward at about 10 mph.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...80 percent.

Long-range GFS has for a while brought it semi-close to Hawaii.

Looking at these forecasts, it won't surprise me to see a stronger hurricane.

It would not shock me either, but models usually come down after the 1st run.

Showers and thunderstorms associated with an area of low pressure
located about 550 miles southwest of Manzanillo, Mexico, are
gradually becoming better organized. Environmental conditions are
conducive for development, and this system is likely to become a
tropical depression over the weekend as it moves westward at about
10 mph.
* Formation chance through 48 hours...high...60 percent.
* Formation chance through 5 days...high...90 percent.

GFS makes this one even stronger than Iselle and also sends it into Hawaii.

Image

CMC looked very similar to GFS, and ECMWF also shows a strong Julio but misses Hawaii to the north.

Satellite images indicate that showers and thunderstorms are
becoming better organized near the area of low pressure located
about 700 miles southwest of Manzanillo, Mexico. Environmental
conditions remain conducive for additional development, and this
system could become a tropical depression at any time during the
next day or two while it moves westward at about 10 mph.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 5 days...high...near 100 percent.

I think Recon could stay in Hawaii after they sample Iselle on Wednesday.

They will likely need to stay there. They start sampling at about 145W?

That's what they did back in the 80's and 90's when the EPAC was in its heyday. They would sometimes fly into storms on their way back as well.

I think it's as soon as it crosses 140W.
