Satellite data along with ship and buoy observations indicate that
a broad low pressure system has developed several hundred miles
south-southeast of the Gulf of Tehuantepec. Shower and thunderstorm
activity is currently disorganized, but environmental conditions are
expected to be favorable for this system to develop into a tropical
depression by the end of this week while it moves toward the
west-northwest.
* Formation chance through 48 hours...medium...30 percent.
* Formation chance through 5 days...high...80 percent.

Very favorable environment does this on intensity.

[TropicalAnalystwx13]

92E should have no problem intensifying into a major hurricane given wind shear near or below 10 knots, SSTs of 28C to 30C, mid-level RH near 80%, and increasing Ocean Heat Content through 120 hours. I think this will peak as a Category 4 hurricane.

You don't think it may get close to cat 5 or even reach it?

[Yellow Evan]

I see this peaking anywhere from 90-160 knts.

It's possible, but I'm not going to outright forecast a Category 5 hurricane this far out.

Yea, to reach Cat 5, you kinda need luck as in no ERC's and when you predict a Cat 5, and it busts, let me say this: it's not a good situation all around. I've burned those bridges before.

[Yellow Evan]

According to Ryan Manue one of his pictures on twitter, CMA makes this fairly strong as well.

[Steve820]

This is a dramatic invest. It might have a shot at C5 status in the long run due to upcoming favorable conditions. Personally, I'm predicting it to peak at around 155-165 mph so we could see future Hurricane Marie be a very powerful one.

Yeah one wouldn't predict a cat 5 you just got to let it happen. One thing is fore sure most models suggest this system will be very large. Something more reminiscent of a Rick etc. It's not going to behave like Amanda or Cristina, I think the ceiling potential will higher with some luck as you mention. Doesn't mean it will reach it but definitely favorable.

It's fairy large, but so far, it's ahead of schedule. It's not one of those monsoonal ITCZ breakdowns you sometimes see.

[CrazyC83]

I see no reason why this storm can't become an absolute monster.

Interesting week ahead for sure...I also wonder how the potential Gulf storm (or lack thereof) could influence its track? Could a stronger "Cristobal" act as a blocker for "Marie", or draw it inland?

As said 92E should have no problem reaching Cat.3 or higher. But 160kt? I'm not sure about that
I bet even Linda won't receive the 160kt rating today due to a more conservative ADT version

[cycloneye]

I would want to see recon go and get the data but I know they will not go.

[CrazyC83]

To get an idea on the big picture track, we would also need to know what 96L/Cristobal? does as well. The G-IV jet would have to sample the entire region in both the Gulf/Caribbean and EPAC.

Not too much, at least early on IMO. I'd lean towards the second case.
