appeas recon is in Bonnie coc now.. and it appears that the surface center may be to the sw of convection and the center may be on the wsw side of the big island there in Bahama's... wsw of city of Congo Town.

Bonnie as of 12:15 am ET...is north of progged forecast track points by about 1 degree latitude.
What strikes me is that Bonnie currently seems to be more than a degree due East if not slightly ENE of the projected 8 AM position (according to the 11 PM update).
Quote:
FORECAST VALID 23/1200Z 24.4N 78.7W
MAX WIND 40 KT...GUSTS 50 KT.
34 KT... 75NE 30SE 0SW 30NW.
Now granted, for the "center" I 'm using just to the SW of the apparent blow-up in convection seen in the water vapor and AVN loops (yes, I know the pitfalls of this). And of course, to prove how misleading these sat images can be, the latest recon has the center even lower than I was estimating (thx Storm Hunter).
Still, Bonnie is going to need to start moving due west soon, or the may need to adjust the forecast even more to the north (east).

doesn't appear to be TS Bonnie on first pass... ***only thing i can think is there may be two centers... and a more stronger center could be forming under the blob of convection to the NE of this center***

Stupid question/comment...Do they ever send the airplane to the wrong place?
One heck of a good imitation of a tropical storm at the center of all that convection and banding.

Looking at sats... the convection is very well defined near Nassau Bahama... with recon showing one center to the SW outside of the convection... i'm looking for surface data to prove that i think Bonnie may have reformed to the NE under that convection... there appears to be two hot towers in recent sats that have stayed well centered so to speak in that area of storms and is very symmetrical for a couple of hours. Nice banding on this feature... recon just completed the SE Outbound leg... turning north and heading towards the Nassau.
**one thing i noted... to the NE of all of this... there appears to be some strong winds aloft coming towards Bonnie..** G-IV flew yesterday evening in GOM and into the Atlantic around Bonnie.. so we should be getting good data into models now until landfall in GOM

actually pre-flight briefing which happens about hr before takeoff... has a "target area" they think will be where when they arrive on scene they should find there invest/low/storm, etc... When they arrive on scene... the on board radar which is located in front of C-130 for Air Force planes and underneath on P-3's... will give them a real time look to the Met. on board... who will direct the pilot to what they think is center... the AF planes all have screens at each position on the aircraft so they all know whats going on and all agree and know what to do/jobs... the navigator usually will then pick out the butterfly invest pattern they will fly... and the Met. on board will make and ask for special procedures if something comes up... like a circle in the center... or a stuff like that... usually the met will ask when they arrive in center area.... they will give directions to pilot.. "turn left 10 degrees...etc. so they pass dead center.. and when they pass... Met./wx officer will tell dropsonde tech to release the GPS dropsonde... and they will monitor via RF the GPS dropping to the surface.. all while HDOB is running and the SMRF is running... all lasting about 10 hrs or so per flight. vortex data is reviewed and check and then add reports and then sent VIA sat Internet to servers for to use.... so in reality there not sent to wrong area... but with systems like Bonnie... things can change very quickly. Its up to crew on board to find and report there infromation back to . They do have Sat phns... and Sat Internet on board if they need to talk to or whomever.

Based on the location of the last 2 center fixes by RECON. It appears that the center of Bonnie will pass just south of the mainland. This would place Bonnie on a track over the Keys and over the Florida Straits.
In other words Bonnie would be passing over the Gulf Stream for a longer period of time than if she were to pass over the mainland. Window of possible/ probable intensification would be longer.

Satellite imagery early this morning shows Bonnie elongated NW to SE as wind shear continues to impact Bonnie. The system continues to move at a pretty good clip to the WNW. Wind Shear analysis continues to depict strong winds aloft over the state of FL and nearing 30 and 40 knot upper winds and despite the ULL moving westward the speed of the system is fast enough to continue to be impacted by the upper environment. Radar imagery at 0.5 degrees has the circulation on scope however the circulation is not completely wrapped around the system supporting discussion at the possibility the system may become an open wave.

Mets here in Orlando are predicting low 90's, high clouds, and maybe some rain. They don't see much chance of intensification as she moves through the straights, maybe a little. Maybe some intensification as she moves into the central gulf. Let's hope this low intensification forecast holds true. Nobody wants to see a strong storn hit the gulf right now, more than ever.

Would not just keep an eye on the exact storm track. Most of the convection is to the North and North East. The Tampa-Clearwater area is expecting blustery conditions this evening with heavy thunderstorms.

The system becoming declassified would not be a big surprise considering the shape it is in. Is it me or is that ULL conslidating?

Bonnie (if you can still call it that) really got squished between the high to the NE and low to the SW. The strong is elongated and moving at very fast clip. Winds in the middle Keys are 14 mph gusting to 35 mph. Considering the storm is moving at almost 20 mph itself this will be over before it even begins. All the weather is so displaced from the center there is almost no way this will be a TS by the time it reaches the west cost. Pretty much a non-event aside from a strong breeze and some passing showers. We have had afternoon thunderstorms produce worst conditions. Based on the radar it appears that the center will come ashore in Coral Gables/South Beach versus the upper Keys. Still seems to be tracking north of forecast just like yesterday.

I agree that it appears to be tracking slighting more north. I also agree that here on the West Coast we get afternoon storms that gust well over 40kt on a regular basis.

But is seems that you (and I, and others) think the "center" is in a different location than the . Based on radar, I'm thinking more along 25.1 N 79.3 W, compared the the 's loc of 24.7 N 79.8 W.

Looking at Miami radar indicates that initial landfall will be just N of Key Largo and traverse the peninsula over the Everglades. Weather over the southern half of FL will deteriorate and, with some afternoon heating in Central FL and the instability introduced by Bonnie, the thunderstorms will pop up. The environment is still not conducive to intensification and the relatively rapid motion of Bonnie will also inhibit strengthening.

Miami Storm relative velocity loop is showing what appears to be 2 or 3 vortices rotating around the center. Northernmost vortice is just east of Miami while the southwestern most vortice is just east of Key Largo. Look for the empty circular areas.

When you look at satellite loops of Bonnie, you get a sense that you are watching a mirror image of a dying hurricane as it races past Nova Scotia as it merges with the Easterlies.
I think under the present circumstances, bonnie won't insensify much if at all. In fact if it weakened into an open wave, I wouldn't be surprised.
Here in La. they are predicting some blusterly winds and some rain, but we could use the rain and some cooler temps.
As for the oil, the fears are it could get pushed more inland, but maybe that won't happen and the choppy seas will help agitate the GOM and it will in fact break the oil down and help it dispurse.
