Re: ATL: INVEST 93L - Discussion
Why do I have a feeling this might be another Humberto, takes a while to consolidate and then after forming go through RI and becomes a strong Cat 1 low Cat 2 before landfall?

Re: ATL: INVEST 93L - Discussion
GFS does initialize a low in the vicinity of the invest location, but then it develops another low north of the Yucatan. Very odd. I don't trust it.

The systems broad circulation is becoming much more evident this morning,I think we should have a depression by Sunday

Would be similar to Cindy 2005..low reforming to the north and threatening northern Gulf Coast

Re: ATL: INVEST 93L - Discussion
The forerunner of this topic was locked just after Tolakram posted a beautiful loop of the center of the system (http://i.imgur.com/ndf3Szj.gif).
Maybe one of the mets can comment on this: About halfway through the loop, the large convective cell closest to the center of the frame is the source of a semicircular set of clouds that, at the playback speed, look like shock waves spanning roughly 6:00 to 12:00 (centered on the cell). They move out radially from the center, with no evidence of Coriolis effects at all. Are they associated with outflow boundaries from that cell? I guess the timing could be right...
Thanks in advance!

Funny too that this very well could be Cindy assuming Invest 92L becomes Bret.

Re: ATL: INVEST 93L - Discussion
Now that we have a tightening broad low we have something to track and while Texas is still my area of choice for this system the GFS solution can't be completely discounted as we seem to have a very slow NNW motion to this broad low

Re: ATL: INVEST 93L - Discussion
Have the models ever whiffed on intensity? In terms of predicting low intensity, and then out of no where the storm gets stronger than they thought? Just curious. I am not saying this one will do that.

All the time. We are pretty inept still with any type of intensity modeling.

Thanks. I forgot in the past if there were any major fails by the models. Is shear supposed to be high with this system?

I noticed that too. they look like gravity waves to me. fantastic loop for sure.

I haven't looked at the shear maps in a few days. Initially the N Gulf was supposed to have pretty strong westerly winds up to 50mph as of early this weeks air pattern forecasts.

Re: ATL: INVEST 93L - Discussion
2pm TWO. Up to 30/80%.
Satellite data and surface observations indicate that a broad low
pressure area has formed over the Gulf of Honduras, and the
associated shower activity is showing signs of organization.
Continued gradual development is expected as the system moves slowly
northwestward across the Yucatan Peninsula during the remainder of
the weekend, and a tropical cyclone is likely to form early next
week over the southern or central Gulf of Mexico. Regardless of
development, heavy rains are likely to spread over portions of
Central America, the Yucatan Peninsula, Jamaica, the Cayman Islands,
and western Cuba during the next several days. An Air Force Reserve
Hurricane Hunter aircraft is scheduled to investigate this system on
Sunday, if necessary.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...high...80 percent.
