The curse of the NHC stikes again , this looks terrible this morning, as shear isn't allowing very much sustained convection.

I fully understand why they made it a TD though given the closeness to the US coastline.

Five is falling apart, will be a remant low shortly.

That's another one with promise dissipated. The more these systems fall apart because of dry air or shear, the more cynical I've become about 2010 activity predictions.

The remnant low of TD5 is bringing some very high rainfall totals over Louisiana, particularly the New Orleans area at present. Upto 5 inches of rain has fallen, which is causing some flooding. The remnant low has stopped moving north and is actually inching westwards. Shear has fallen, and if ex-TD5 can move slightly south of west, it may manage to move back over the toasty waters of the GOM. Models have been toying with this idea over the last day, so there is a possibility and it needs to be watched.

This is a very interesting system indeed. Looks likely to re-generate, which if it does, it quite some achievment as TD5 degenerated 5 days ago. The system has remained over land for about 4 days of this time, so the fact that it already looks quite healthy again and has not even emerged over water yet is impressive. NHC upped the chances to 50% in the latest TWO.

Thanks for the imagery Cookie :)

Now up to 60% chance now with lots of convection bubbling up.

I'm guessing this kinda system is very unusual. Are there any records for the longest a depression has spent over land before managing to reach water and re-develop into a TD or storm?

Its upped to 60% now. The best chance for it to develop is to cross Florida quickly, heading south east, if it can do this then it can meander and strengthen before it gets caught by the Jet Stream in around 48 hours.

I think it's moving westwards SB, looks like clipping the Louisiana coast and into the warmest waters in the Gulf.

Recon are in the remnants now, reporting pressure of 1009mb, but I think they haven't reached the centre yet. Plenty of convection with ex-TD5, and it appears to be getting better organised. We will soon see if recon find data justifying the system to be reborn. Surprisingly, it is practically where it dissipated! The remains are currently moving westwards quite quickly so may not have much time over water.
