ShearMap is down but SST's are showing 30C.

This shows that northward moving outflow boudary pretty well.

Outflow

Quoting Drakoen:


Yea. I would focus more on the area around the Yucatan

\


100% agree. the southern blob will collapse by late day.

this outflow boundary will enhance the northern LLC IMO.

Quoting kmanislander:


The one that takes off to the N very quickly ?. It is partially obscured so the still would not pick it up.

Yes, also on the eastern quad.

These two graphics don't make sense, unless there is a low off Honduras and discount the low forming in the GOM from developing. ???

Quoting angiest:


2.5 feet of motion (mostly horizontal in that area) isn't a whole lot. It is believed by some seismologists that the San Andreas proper north of the border may have up to 30 feet of motion built up in it. The 1906 San Francisco earthquake involved up to 20 feet of movement.

Houses and other buildings don't respond well when the earth moves 2.5 ft.
My brother's house sits almost on top of the San Andreas, not exactly on top but way too close for comfort.

regarding 96L the models are crap..the system is decoupled. but, i see it making substantial progress today on rectifying that. I believe that it will pull together some where between the mid level swirl you see south and east and the low evel swirl near the yucatan. Lets see if this does not happen. The witches brew is starting to come together i think.

Quoting StormW:
Here's food for thought, what if...the scenario is different? Let me surmise this...look at the 06Z Surface analysis map, then think about this...the Tropical Wave seems to be "drawn incorrect". Look at the waves behind it, look how the axis runs through the upward "kinks" in the isobars, then down to the ITCZ. Look at the wave near the Yucatan. Goes from the south tip of the "kink", straight south. My thought is, it is oriented more like the wave at the Antilles, and draped across the Bahamas and Cuba, and the low we are seeing in the channel, is the southern end of the wave axis, while the stuff near Honduras is the monsoonal stuff of 96L.

Interesting thinking, but you would have to believe the NHC would know where the wave axis runs through ?.

I suspect that they have "comingled" if I might put it that way the wave passage with 96L having its true genesis from the ITCZ pushing back into the Caribbean and that has created the uncertainty over tracking as well as graphical depiction.

Yes

Wednesday and Thursday looks wet as another system in the Caribbean heads for South Texas. This tropical system could turn into Bonnie.

Quoting IKE:
My amateur guess is...they'll lower the pct. on 96L further on the next TWO and 95L looks near land...close to death....

I'll go w/a 20-30% chance on 96L. I'd say 20%, but I don't think the NHC will....

Nah. We are one day closer to Bonnie than yesterday. I think the storm is getting its act together as we type. It will stay at 40% minimum.

Models from overnight now showing system not developing and moving more toward Texas.

Quoting RecordSeason:
Rumors of a record season were greatly exaggerated.

poor guy just joined the blog to see 45 storms before september. dry your eyes :( sob sob

Agreed. Right near 19 N and 85 W.

NHC 72 hour:

Quoting StormW:


Well, the only problem I have with them knowing where the axis is, is that if the predominate flow is running SE to NW in the low level steering, why is the wave moving due west? On a surface map, without knowing where the wave axis is, that's how we track waves, by the kinks in the isobars.

I agree it is odd. Another case study for the 2010 season LOL

That is true, merely stating that it was not a particularly large movement of the earth, even as the San Andreas system goes.

...as the invests turn, so do the days of our lives...bbl

Have to say it is slightly disappointing, went to bed last night with 4 circles kind of looking forward to seeing what was up this morning

Get up, check the TWO and one circle is gone and the other 3 were all lowered lol

just a matter of time before the season is a bust people come out

shouldn't be disappointing buddy! Hate to think how a developing storm on 96L forecast track would affect the gulf coast. Little yellow circles = happy faces

Morning Tex. :) Lol. As usual they're no help at all. I have no idea what's happening with 96l this morning. So that's a good thing.

yeah, not sure. It doesn't look as good as it did yesterday, although that could change....

What we need to watch for today is growing convection towards the cyclonic curvature, that would be a sign that the northerly flow is relaxing some over the system.

i thought they were here allready if im mistaken we've had like ten of them so far

Updated 925 mb sat and vort overlay map

4 very distinct areas. 95L, 96L " North", 96L "South" and inside the Windward islands.

Notice the two areas associated with 96L have a separation to them.

Some of the Cuban radar sites seem to be down the last hour, at least those in the west. This mosaic shows some of the storms off the Yucatan earlier. If the sites come back online, could be helpful.

latest radar looks like 95L starting to move more NNE could be wrong though.

Yeah. I know. :( But I been wanting to use the smiley guy and thought I'd better get it in there before his sad friends have to come back out. Lol.

Interesting and has my attention...

95L has more vorticity than 96l..easily

LOL

Quoting Patrap:

These are the new ones? Look pretty much like yesterday.......

Buoy 42056 should be watched for falling surface pressures.

Quoting StormW:


I agree!

One other point though, with these monsoonal types, they hang around and take time, so why would a LLC kick out and move quicker than the rest of the energy?

I skipped the lecture where they went over that material LOL

I am about to go to bed, Don't be surprised if the 3 circles become 5. Last night it went from 2 to 4 while i was sleeping. Fingers crossed it stays only 3.
Goodnight all.

I will say it was one heck of an earthquake. Strongest I've felt. We've had a bunch of aftershocks too that have been up there as well. You start to get used to it really but every now and then, one really gets your attention.

StormW, I'm trying to follow what you and kman are talking about. Is it possible the this system is trying to break in to two?

Hi all... long time! My internet has been out since last week. Not cool at all.

We made it through the 3 days of rain from Alex. Now I see we a few new things to keep our eyes on.

..Please.

Carry on
