Jeanne Sat loop ...whats the black area?

Does the black area indicate stronger convection...or lack of?

Also ...nice IR Satellite Image...

The purply color is EXTREMELY deep convection. I really haven't seen any storm this year w/ such strong activity near the center of the storm like that. Jeanne seems to be very efficient at strengthening w/ what she's given, and now that she is moving over warmer waters...bam! The convection has nearly wrapped around the eye, and it looks to me like the northern eyewall is open now. The rumor of the NHC talk about a Cat 4 may very well ring true if the dry air can be fought off. Also, Sanibel is no longer online, but the flatness of the outflow he/she was talking about is totally gone now. In fact, it has gone bonkers towards the WSW.

It's called "blackout"

It's smoke! The thing's erupting!

Or...Those cloud tops have reached absolute zero!

Honestly, I don't know. It's reading a different temperature there, or it's a-a-a-anomalous.

EVIL!

And very cold cloud tops indicative of very very strong convection.

Check out the DVORAK! Holy moly!

That needs an entire new thread!

I believe Charley had this gray convection on this specific satellite for a period of time.

Sooo... it could be deep convection....or an anomaly.....
Ok. I feel better now.... :roll:

Thought I saw a slight shift to the NW in the entire system but then
the convection to the S enlongated so it doesnt matter too much. Could just be a wobble. Like ppl have already said...dont put a pinpoint on landfall as to who gets affected.

Does appear that the entire S quadrant has deeper convection at this point than the north... but does that mean only precipitation is heavier there while winds are still higher in the N and NE quadrant?

That black "anomally" still there on the latest image 0745.

BTW...that Dvorak looks like abstract art. Someone will probably
buy that off of u for $$$

She's due west and looks like rapid intensification is in progress. If this continues wrapping around, she'll be a cat 3 before long, maybe more.

That's no anomally but very deep convection. Lisa had similar convection for the last couple of days but well displaced from her center.

BTW, if the convection becomes extremely deep, the color changes to white - very rare to see. You'll sometimes catch a glimpse of this occuring over Colombia (in the southwest of the IR satellite photos/loops).

No!!! Its strengthening!! Im getting out of town.
