ATL: GORDON - Post-Tropical

[Canelaw99]

TS genesis pretty much right over my house! Cool beans!

My thoughts this morning too!!! Nice to see a fellow Homesteader on S2K!

For some perspective, Gordon wasn't supposed to be a 45mph tropical storm for another 30-36 hours.

To be honest if you had a high density surface observation network (like in South Florida), you could find TS winds in almost any cluster of thunderstorms in the tropics. It's not really any more organized than it was six hours ago.

Going to have to disagree with you there. I was watching this 6 hours ago. The radar presentation is vastly different and much better organized. This looks like a strengthening system on radar and satellite.

Yeah, radar presentation really improved during the past 6 hours with plenty of light westerly winds being reported near Islamorada despite its fast pace towards the WNW.

In the past, you would be correct. However, the PTC designation is for advanced warning which is what the NHC did for South Florida, and the Northern Gulf. No one should have been unaware of this system.

Yup. Feeling it too in Miramar (Dykes Rd and Miramar Pkwy)

AND THE FLORIDA KEYS WITH HEAVY RAINS LIKELY...


SUMMARY OF 830 AM EDT...1230 UTC...INFORMATION
----------------------------------------------
LOCATION...25.1N 80.7W
ABOUT 20 MI...30 KM W OF KEY LARGO FLORIDA
ABOUT 85 MI...135 KM SE OF MARCO ISLAND FLORIDA
MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H

WATCHES AND WARNINGS
--------------------
CHANGES WITH THIS ADVISORY:

A Tropical Storm Warning has been issued for portions of South
Florida from Golden Beach to Bonita Beach, and for the Florida
Keys from Craig Key to Ocean Reef, including Florida Bay.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Storm Surge Watch is in effect for...
* Mississippi-Alabama border westward to the Mouth of the
Mississippi River

A Tropical Storm Warning is in effect for...
* Golden Beach to Bonita Beach
* Craig Key to Ocean Reef, including Florida Bay
* Alabama-Florida border westward to east of Morgan City, Louisiana,
including Lake Pontchartrain and Lake Maurepas

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning areas.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND OUTLOOK
----------------------
At 830 AM EDT (1230 UTC), the center of Tropical Storm Gordon was
located by NOAA Doppler weather radar and surface observations
near latitude 25.1 North, longitude 80.7 West. Gordon is moving
toward the west-northwest near 17 mph (28 km/h) and a west-
northwestward to northwestward motion is expected over the next
72 hours. On the forecast track, the center of Gordon will pass
over the southern tip of the Florida peninsula this morning, move
over the southeastern Gulf of Mexico this afternoon and evening, and
reach the warning area along the central Gulf Coast by late Tuesday
or Tuesday night.

Surface observations and radar data indicate that maximum sustained
winds have increased to near 45 mph (75 km/h) with higher gusts.
Additional strengthening is forecast during the next 48 hours.

Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.

The estimated minimum central pressure is 1009 mb (29.80 inches).


HAZARDS AFFECTING LAND
----------------------
STORM SURGE: The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline. The water could
reach the following heights above ground somewhere in the indicated
areas if the peak surge occurs at the time of high tide...

Destin Florida to the Mississippi-Alabama border...1 to 2 ft.
Mississippi-Alabama border to the Mouth of Mississippi River...2 to
4 ft
Mouth of the Mississippi River to the Louisiana-Texas border...1 to
2 ft

The deepest water will occur along the immediate coast near and to
the east of the landfall location, where the surge will be
accompanied by large waves. Surge-related flooding depends on the
relative timing of the surge and the tidal cycle, and can vary
greatly over short distances. For information specific to your area,
please see products issued by your local National Weather Service
forecast office.

RAINFALL: Gordon is expected to produce total rain accumulations of
2 to 4 inches over the central and northwestern Bahamas, the Florida
Keys, and South Florida through early Tuesday. Isolated maximum
amounts of 8 inches are possible over the southern Florida
peninsula.

Gordon is expected to produce total rain accumulations of 4 to 6
inches over southern Alabama, southern Mississippi and Louisiana,
with isolated maximum amounts of 8 inches through early Thursday.

These rainfall amounts may cause flash flooding.

WIND: Tropical storm conditions are occurring in the warning areas
across South Florida and the Florida Keys, and those conditions
should continue through the afternoon. Tropical storm conditions are
expected within portions of the central Gulf Coast warning area by
late Tuesday.

What's the shear look like now? Moderate?

What are you guys looking at?? If this isn't a tropical storm, I'm not sure what you want to see on satellite and radar. It doesn't get any more classic of a look for a developing tropical storm than what you're seeing now.

In the past, you would be correct. However, the PTC designation is for advanced warning which is what the NHC did for South Florida, and the Northern Gulf. No one should have been unaware of this system.

Most people don't pay attention to a PTC especially during a holiday weekend not like they would actual warnings. It also doesnt get nearly the hype. The average person doesnt keep their head buried in the weather. Not a big deal though, we're used to this kind of weather.

This makes sense, also decoupling easterly winds over Cuba during the night to the south of the vorticity also helped so that it could gain some southerly inflow, IMO.

[Ivanhater]

Is it me or is the center passing over mainland south Florida..which is north of the cone yesterday?

Huh? Guess we've not been watching the same system. Looks like a T.S. to me

It is further North. Originally was thought is would set up at Marathon Key but now over Key Largo may even be a bit further North

Not the fault of the NHC. They warned.

But like you said, it's nothing that anyone can't handle.

its not about the look, its about whats happening at the surface, clearly the nhc sees a closed off center and enough wind to go TS, they make the call, we can disagree just like 2 hours there were some saying it should be classified...bottom line is the real weather doesnt change and nothing really changes except we dont have to waste any more board space going back and forth..next argument will eba bout hwrf which started yesterday..cheers

we just had ,8 in 45 minutes so up to 1.57, still looking for over 4 today which based on radar shouldn't be a problem..6 would be an over achiever
