Recon now heading to the south

[Aric Dunn]

Probably forming just south of 14.5N, maybe around 14.3 or 14.4N.

Not well defined but that wind shift is quite tight to be fair. Recon enedws to go south of there to see whats going on and if there is any more change in wind direction.

I will be going to the south to look for any west winds..

Any possible LLC development looks to be on the southern side of the circulation

Recon now heading to the south

Yeah hopefully they look to the south of that wind shift to see how things are going.

[brunota2003]

Correction, they are heading SE. Perhaps they'll be turning back around to the WNW shortly.

There is some SSE winds.

[KWT]

Actually looking at it on that map center is probably very close to where the NHC estimated on its last update...thats an amazing call from them it has to be said.

That is of course depending on that actually being the center of the developing disturbance of course!

[Aric Dunn]

There is some SSE winds.

had a few 168 degree's which is straight south ..

[brunota2003]

There is some SSE winds.

had a few 168 degree's which is straight south ..

Still reads SSE on GE Recon. Though that is not very far from 180 true south.

yeah guess its right on the cusp of SSE and S
