Re: EPAC: INVEST 97E
Showers and thunderstorms associated with an area of low pressure
located about 140 miles south of Zihuatanejo, Mexico, have become
better organized today. Although upper-level winds are not
particularly conducive for additional development, only a slight
increase in organization could result in the formation of a tropical
depression during the next day or so. Later this week, upper-level
winds could become a little more favorable for development while the
system moves west-northwestward at about 10 mph.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...60 percent.

In my opinion, I agree that this looks better than 4E in a way. It's more compact and compact systems are much better at strengthening than large, monsoon like ones which closely reflects 4E. Once 4E moves away, the upper level winds might improve and that's why I think this has a better chance than 4E, as of now. However, I could be very, very wrong so don't take it as official.

I tend to agree. I would not rule out a hurricane. The question here is will it impact land?

Re: EPAC: INVEST 97E
With that sentence about a slight increase in organization it could result in the formation of a TD I would have the % at 60%-80% but is only my take.

When conditions aren't the best, NHC tends to go no higher than 50% it seems with this kind of wording.

The only problem now appears to be 4E/Douglas imparting moderate shear on 97E. Other than that, air on the SSD water vapour imagery is quite moist and the sea, as it's been for the whole season thus far, is like a bathtub.

I agree that it should form. The question is when IMO.

Thunderstorm activity associated with an area of low pressure
located about 180 miles south-southeast of Manzanillo, Mexico,
continues to show signs of organization. Latest satellite data,
plus coastal surface observations and ship reports, indicate that
the low is producing tropical-storm-force winds. However, the system
still lacks a well-defined circulation center. Upper-level winds
are not particularly conducive for additional development, but only
a slight increase in organization could result in the formation of a
tropical storm during the next day or so while the system moves
west-northwestward at about 10 mph.
* Formation chance through 48 hours...high...70 percent.

Impressive! Now, the EPAC would have 2 tropical cyclones existing at the same time before the season's first peak. As for the system, this is looking organized.

Douglas is ruining the potential for 97E to develop. There's too much shear right now, even though it looks organised.

What?! This thing has winds of 45 knots? If this develops, it will likely go straight to tropical storm and be stronger than Douglas in terms of wind speeds!
