Convection blowup SE of BOC (Is invest 99L)

[ravyrn]

Could someone share their opinion as to what is causing that convection blow up just W/SW of the Yucatan slightly inland from SE BOC?

Can be seen here.

[bob rulz]

I was noticing this too. Certainly that is a massive envelope of moisture.

[alanstover]

Yes, it would be interesting if someone more knowledgeable than I could give us some explanation. I noticed this too this morning when I looked at the images of our area. Yesterday the sun finally came out here as invest 98L moved away, but this morning is cloudy again here in SW Guatemala.

Enough with the BOC systems, geeez! J/K, it is something to keep an eye on!

Is 98L being pulled back over the BOC? The visible satellite is looking like a turn is off the coast of Mexico again. Pressures are high and shear is still strong BUT this has been an interesting season so far.

NHC is calling it "upper level diffluence" in the latest tropical discussion:

THE GULF OF MEXICO...
TROPICAL DEPRESSION BONNIE IS OVER THE NE GULF OF MEXICO. SEE
ABOVE. IN THE UPPER LEVELS...AN UPPER LEVEL LOW IS CENTERED OVER
THE W GULF OF MEXICO NEAR 28N94W. UPPER LEVEL DIFFLUENCE S OF
THE CENTER IS PRODUCING SCATTERED MODERATE TO STRONG CONVECTION
OVER THE BAY OF CAMPECHE AND S MEXICO FROM 18N-22N BETWEEN
95W-99W. EXPECT... BONNIE TO BE ALONG THE NORTH CENTRAL GULF
COAST IN LESS THAN 24 HOURS.

I guess I should read the updates first before posting, thanks Portastorm! Waves are up, time to go surf!

Yeah just looks like a shear enhanced region of convection, the Caribbean has been convectivly very active, bet we get a big un in October down there...

[lrak]

A lot of turning down there. And the convection has been cranking all afternoon with very high cloud tops.

[TexWx]

Ive been looking from my Iphone all day.

Is there circulation, and any movement?
If so, in what direction?
