While everyone's paying attention to Joaquin, 99L appears to be tightening up on radar as some strong curved bands have developed over the eastern Gulf and a decent circulation about 100 miles west of Tampa is taking shape.

If you also go to NWS long range radar as well, you can see and pick out a circulation as you mentioned about 100 miles due west of Clearwater. It will move inland by tomorrow afternoon somewhere in the Apalachee Bay region. As someone mentioned earlier, this will be the fourth system to impact that region of the GOM this season.

Could the 12Z ECMWF be on to something and we might get Kate before landfall?

Interesting evening in the GOM with 2 Low Pressure systems. NHC/WPC surface analysis with the stationary 1005 mb Low just off the Upper TX coast and the 1006 mb Low just west of the Florida Gulf coast moving north-northeast.

If I am not mistaken, Air Force Reconnaisance aircraft is on its way to investigate 99L and is scheduled to arrive into it very shortly.

EDIT: It appears NHC cancelled that mission late today.

That radar product can't be completely accurate. It shows a trace throughout Pinellas County where it's been raining almost non-stop (outside of an hour break or so) since about 1:30 PM, and that band that went through Orlando originally came through Clearwater around 2:45, while I was driving and the rainfall was so intense I could hardly see at one point. What's funny is that band petered out as it reached Pasco, then re-intensified late this afternoon near the Hernando-Citrus border as it arced ESE-SE into inland central FL.

thats exactly what happened. totally skipped us here in southern hernando county. I did hear distant thunder though. that line got real strong north of us. hearing thunder right now too.

Well 99L is a bust here... all the mentions of heavy rain and not a drop.
Today was supposed to be "the wettest day of the week." It's disappointing when we need some serious rain here. :(

For giggles...

The remnant 99L vortex is actually dropping southward through our local marine area. It's now located about 50 miles ESE of Cape Canaveral and can be seen pretty easily on our radar imagery. We tracked it as it moved east across north Florida , where it emerged east of JAX on TUE night, where it turned and started dropping southward since WED morning.
