Edouard makes landfall as a very weak Tropical Storm.

At about 8pm Wednesday night, Edouard finally made landfall on Daytona
Beach, FL as a 35kt TS.  There was barely any convection, so it was
basically a minor wind event.  Since then, he has continued to drift WSW
across the Florida peninsula, weaken to a TD, and has re-entered the
Gulf.  Given the current state of the storm and the very strong vertical
shear, chances for redevelopment are slim to none.  At 15Z today, TD
Edouard was located at 28.7N 83.0W and moving WSW at 7kts.

Elsewhere, there's a broad area of persistent convection in the
northwest Gulf, with an embedded 1009mb Low at 27N 96W.  Conditions are
favorable for this to develop, but its proximity to land might inhibit
that.  It does have an anticyclone aloft, and a fair amount of relative
vorticity, so it's more than the average blob of convection over warm
water.

Also, a tiny vortex that I've been watching since Tuesday morning is
becoming more interesting now.  Located at about 20N 42W, it's got a
well-defined low-level circulation (1016mb Low), but lacks deep
convection.  Although the shear is currently fairly high (35kts), it
should lessen significantly by the weekend, allowing the system to
perhaps get better organized as it tracks west at 10kts.

Lastly, the tropical wave exiting Africa now is one of the more
impressive ones of the season.  All indicators I typically look at are
favorable for it to develop fairly far east.  The convection is centered
over about 12N 12W.

FYI, the next names on deck are Fay, Gustav, and Hanna, not that I'm
anticipating that all three of these items of interest will become named
storms.  The climatological peak of activity in the Atlantic is Sept 10,
so perhaps this flurry of action will help verify that.

Dolly out of the picture, Edouard creeping toward Florida.

As early as midday Tuesday, I noticed what appeared to be a front coming
off the storm, indicating that Dolly was losing her tropical
characteristics.  Well, NHC issued the 25th and final advisory on Dolly
this morning as she was absorbed by a front.  At 15Z the pressure was
estimated at 1009mb and a center could barely be discerned.

Edouard has remained a TS in the face of 25kt northwesterly shear.  The
convection has actually become more centralized, but not enough to cover
the center itself.  A Tropical Storm Warning is in effect for much of
the northeastern Florida peninsula and some of extreme southern
Georgia.  He is expected to pass over the peninsula from Flagler Beach
on Thursday morning to Homosassa Springs on Friday morning (weakening to
a TD), then re-enter the Gulf (re-intensifying back to a TS).  At 18Z
today, TS Edouard was located at 29.8N 80.5W and meandering westward at
3kts.  Winds are still 35kts and the pressure is up to 1009mb.

Dolly still a Tropical Storm, Edouard forms and sits off of Florida coast.

Dolly never made it to hurricane strength, despite how likely it looked
on Friday morning.  It seems that she ingested a lot of dry air from the
Sahara, and combined with a slight dip in SSTs, intensification was
thwarted.  However, she has maintained TS status and has leveled off in
terms of intensity.  At 15Z today, she was located at 21.5N 53.0W
(approximately 1100km away from the northern Leeward Islands) and
tracking N at 12kts.  This means that she has begun recurving, and will
probably not make it any further west than 55W.  Maximum sustained winds
are at 45kts with 1000mb MSLP.

TD5 formed on Sunday evening just 115 miles east of Daytona Beach, FL. 
At 06Z on 9/2, it was upgraded to TS Edouard, based on virtually every
tool we have: aircraft recon, ground-based radar, surface observations,
and satellite imagery.  He formed in an environment of moderate westerly
shear and meager steering flow, and that has changed little since then. 
At 15Z today, Edouard was at 30.3N 78.6W and stationary.  Winds were
55kts and central pressure was 1003mb and this may be his peak
intensity.  The convection is diminishing and the westerly shear is
increasing, so although he's forecast to loop around and hit the Florida
peninsula on Thursday morning near Daytona Beach, the intensity should
not be alarming (despite the rather warm SSTs he's over).  If he behaves
as expected, he should be a moderate TD or a weak TS at that point. 
There is a Tropical Storm Watch in effect for parts of the northeastern
Florida peninsula.

The only other item to mention is a well-defined surface circulation at
about 18.5N 30.0W.  Although the low-level vortex (1013mb Low) shows up
very well on VIS imagery, there is little convection and the shear is
brutal.  Westerly shear is already 40kts and will be increasing to
50-60kts in the next day or so.
