I'd downgrade her to an open wave at this point but with the heavy convection, shear lessening, the ULL weakening in the FL straits, and generally W-NW movement now I won't be at surprised if she redeveloped down the road.

[tropicwatch]

Based on what the HH are finding, I don't think the NHC will kill it completely. Minimal TS or TD.

Late night a backup is performed that takes Storm2K offline for a few minutes, FYI. Not sure if it was related or not.

that makes sense. Thanks tolakram

[Weatherboy1]

Yeah, I would think they'll give this thing another six hours til the 5 p.m. before killing her off just in case she's fighting back. But you never know.

They will probably keep it at minimum TS at best at 11a.m. my best educated guess.

[tailgater]

Chantal position sure is displaced from it's 850mb vorticity, also note Southern Fla.

[Janie2006]

What's the current forward speed?

[artist]

for those wanting to know how wind direction is figured here is a chart -

Wind Direction and Degrees

Cardinal Direction Degree Direction

N
348.75 - 11.25

NNE
11.25 - 33.75

NE
33.75 - 56.25

ENE
56.25 - 78.75

E
78.75 - 101.25

ESE
101.25 - 123.75

SE
123.75 - 146.25

SSE
146.25 - 168.75

S
168.75 - 191.25

SSW
191.25 - 213.75

SW
213.75 - 236.25

WSW
236.25 - 258.75

W
258.75 - 281.25

WNW
281.25 - 303.75

NW
303.75 - 326.25

NNW
326.25 - 348.75


take this line and look here for the direction the HDOB shows -

142130 1637N 07143W 9249 00802 0137 +206 +200 332003 005 015 000 00
that is a wind direction of 332 which is a NNW wind

[wxman57]

It does look a lot better on satellite now. Sort of like Ernesto last year in the Caribbean. "I'm not dead yet!"

[Dave]

I will be MIA today, strong storms in western IN now, flood watch just issued and expecting a thunderstorm watch within the next 2 hours for us here as well. Strong system approaching our area so will be on weather here locally. Thanks to all who are covering the recon side of Chantal.

[artist]

[northjaxpro]

Yes, look at that increased vorticity at 850 mb up around the southern tip of Florida. Very interesting. Is that feaure in the Florida Straits beginning to get its act together slowly?

[DESTRUCTION5]

It does look a lot better on satellite now. Sort of like Ernesto last year in the Caribbean. "I'm not dead yet!"

Reminds me of the Ernesto that was supposed to go to TeX but ended up east coast of Fl as a slight breeze...not sure when that was.

[cycloneye]

Stays as TS Chantal!

Take care Dave, and stay safe! I am sure some of us can help out here.

Something tells me a lot of rain is headed my way!
