nice nascar lineup on DK this past Sunday.  Too bad you had to split first place 

Thanks

 

just drove home from Trinity over to Wesley Chapel. Pretty decent rain but the winds are still pretty calm. Been very uneventful so far for me but the night is still young.

Wow, shear wins. I've never seen a hurricane get smushed like that. Like a bug against a windshield. 

I'd be so depressed if I was chasing this thing or if I lived in Tampa, would be the same feeling as doing an entire 8 ball of cocaine and running out.

LOL yeah I remember Don fizzled in like two advisories in South Texas years ago.

The radar presentation has really crapped out over the last hour.

Definitely looks better for us. The strongest winds are a couple hours away, but driving sideways rains are not an issue right now. We are good on rain lately, don't need a few inches.

Looks like drier air and clear skies for morning!

Unreal how quickly the inner core dissolved on radar.  I'm in St. Petersburg and we're in what should be a very strong inner band and it's a total non event outside right now. Little rain and a little wind, but nothing to write home about.

I wouldn’t count this storm out yet. It’s literally done this every day just about since it was named. Gets going, starts to get an inner core, then gets disrupted by shear/land/dry air. It could cycle back quick with a new convective burst. Just one of those systems.

WS National Hurricane Center Miami FL       AL052021
1100 PM EDT Tue Jul 06 2021

After an earlier flurry of convective bursting and even the 
development of a eye in radar imagery, Elsa appears to have leveled 
off over the past couple of hours. Between 2100 UTC and 0000 UTC, 
WSR-88D radars from Tampa and Key West indicated areas of average 
Doppler velocities of 75-85 kt between 8000-13,000 ft, which were 
co-located with convective bands consisting of 50 dBZ and higher 
reflectivity values, which equates to at least 65 kt surface winds. 
Elsa's center also passed just barely to the east of Buoy 41023 
around 2100 UTC, producing a sustained wind of 49 kt at 3-meters 
elevation, which equals a 10-meter wind speed of 55 kt on the west 
side of the cyclone. The strongest 850-mb flight-level wind measured 
by an Air Force reconnaissance aircraft so far has been 74 kt. 
However, radar data indicate that the aircraft just missed the 
strongest winds in the convection by only about 5 n mi. The initial 
intensity is being held at 65 kt just in case convection redevelops 
around the ragged eye feature later tonight.

Elsa is moving northward, or 360/12 kt. This motion should continue 
tonight and early Wednesday until landfall occurs across the 
northwestern Florida peninsula. Thereafter, a gradual turn toward 
the north-northeast is expected by late Wednesday, followed by some 
acceleration toward the northeast on Thursday as Elsa rounds the 
western periphery of a deep-layer subtropical ridge and gets caught 
up by the southwesterly flow ahead of a mid-level trough. The 
official track forecast lies between the simple and 
corrected-consensus tracks models and the previous NHC track 
forecast.

Elsa's inner-core convection looks pretty ragged right now, but the 
vertical structure has improved based on the reconnaissance data, 
which indicate that the low-, middle- and upper-level circulations 
are nearly vertically stacked now. Elsa's ragged eye feature along 
with the very warm water beneath the cyclone and the upcoming 
nocturnal convective maximum period could combine to allow 
convection to redevelop. However, proximity to dry mid-level air 
just to the west should prevent any significant strengthening from 
occurring. After landfall, rapid weakening is expected due to 
increased frictional effects and Elsa's small size. The pressure 
gradient, however, is forecast by the GFS and ECMWF models to 
increase between Elsa and a sprawling surface high pressure system 
over the western Atlantic, which should act to increase the winds to 
tropical storm force near the coastal areas from Georgia to North 
Carolina on Wednesday and Thursday. The new NHC intensity forecast 
is similar to the previous advisory and follows the consensus 
intensity models HCCA and IVCN.


Key Messages:

1. Heavy rain will impact Cuba tonight resulting in significant 
flooding and mudslides. As Elsa moves across the western and 
northern Florida Peninsula through Wednesday, heavy rainfall may 
result in considerable flash, urban, and minor to isolated moderate 
river flooding.  Mid to late week, heavy rainfall across southeast 
Georgia, South Carolina, North Carolina, and southeastern Virginia 
may result in isolated flash and urban flooding, with considerable 
flash and urban flooding possible across coastal Georgia and the 
Lowcountry of South Carolina.

2. There is a danger of life-threatening storm surge along portions
of the west coast of Florida tonight and Wednesday, and a Storm
Surge Warning is in effect for that area.

3. Hurricane conditions are expected tonight and early Wednesday 
along a portion of the west coast of Florida, where a Hurricane 
Warning is in effect.  Tropical storm conditions are occurring 
across portions southwest Florida and will continue to spread 
northward along the west coast of the state within the warning area 
through Wednesday morning.

4. Although the center of Elsa is expected to remain inland of the
coastline from Georgia through the Carolinas during the next couple
of days, tropical storm conditions are expected along much of the
coasts of Georgia and South Carolina.

It collapsed when it finally became vertically stacked :lol: 

I love tropical.

Looked best at highest pressure, when a hurricane looked horrible. Been a weird one.

As far as here, the Fat Lady has not sung yet, but I'm looking forward to sleep in a couple hours or so with power...

Well in all seriousness, while I think we all agree it's not a hurricane, as @NorthHillsWx said this system has a pattern of pulsing up and down. I mean just in the last hour we see more prominent banding features on the east side of the circulation, and the first pass by recon tonight showed 70+ kt FL winds. I can see how Elsa has a burst that brings in some bigger wind to some coastal spot. 

NHC is all about continuity so this isn't terribly surprising.

Radar has a juicy band setting up from Tampa metro to east of Sarasota, will be pivoting thru and dumping during the overnight.  High tide at 320AM with the coc close to due west offshore.  3-5ft surge seems on target, could be a tad higher.

Seems like Elsa is a little behind schedule and the onshore wind will be at high tide.

3-5 is about right based on the history around here. It doesn't take much, and there is wind.
