ATL: EIGHT - Post-Tropical - Discussion

[cycloneye]

The BT will likely have it as a tropical cyclone much earlier though, probably 0600Z or earlier.

You think maybe a TS?

[JtSmarts]

I could sure use the NHC naming this albeit just for a few hours. I need to at least pad my preseason numbers some. I have been taking a beating on my 19/8/4 with a ACE of 125 this year....

You think you have it bad, I predicted 21 named storms this year. Anyway, I wonder if we get a post-season upgrade if some reports of ts force winds are later documented.

[SeGaBob]

If this system could stay just offshore until the 5pm advisory it might could be upgraded to a TS...but NHC says it's moving inland now.

There would have to be some observation of TS wind. That won't happen at Tampico, most likely, and it's not near any buoys or ships. No ASCAT ob yet today. If the descending ASCAT pass hits the western Gulf and there are indications of 34kt wind then it could get an upgrade. If not, then no post-season upgrade.

That was a quick ramp-up from this morning! There's just something about systems that only manage to get to TD status and remain that way there whole life. Probably just my OCD.

Knowing that it will most likely be the shortest lived TC this season I'd rather it just remain a TD.

I agree, something conclusive is necessary - an ASCAT pass would be the most likely reason for an upgrade if conclusive 34 kt winds are found. No surface obs exist supporting such.

If a post-season upgrade is made, it would not get named though. A pressure of 1009 or so is awfully high for a tropical storm as well...

[ROCK]

well someone needs to go out there in a john boat with a barometor and anemometer and get this named.. .Tampico gets hammered every other year. I wonder why we dont stick a buoy out there...sheesh...

[CrazyC83]

Highest I see is 30 kt.

TROPICAL DEPRESSION EIGHT DISCUSSION NUMBER 2
NWS NATIONAL HURRICANE CENTER MIAMI FL AL082013
400 PM CDT FRI SEP 06 2013

THE CENTER OF THE DEPRESSION MADE LANDFALL IN THE TAMPICO MEXICO
AREA AROUND 1800 UTC. WHILE THERE HAVE BEEN NO REPORTS OF
SIGNIFICANT WINDS FROM THE MEXICAN COASTAL STATIONS...TAMPICO
REPORTED A PRESSURE OF NEAR 1009 MB AS THE CENTER PASSED OVER. THE
INITIAL INTENSITY IS HELD AT 30 KT SINCE A LARGE AMOUNT OF THE
CIRCULATION IS STILL OVER WATER. NOW THAT THE CENTER IS INLAND...
THE CYCLONE SHOULD STEADILY WEAKEN DURING THE NEXT DAY OR SO UNTIL
IT DISSIPATES COMPLETELY IN 24-36 HOURS.

THE INITIAL MOTION REMAINS A SOMEWHAT UNCERTAIN 250/5. A
LOW/MID-LEVEL RIDGE TO THE NORTH OF THE DEPRESSION SHOULD STEER IT
GENERALLY WEST-SOUTHWESTWARD UNTIL DISSIPATION.

THE MAIN THREAT FROM THE DEPRESSION IS HEAVY RAINS OVER THE MEXICAN
STATES OF VERACRUZ AND TAMAULIPAS...ALONG WITH THE POTENTIAL FOR
FLASH FLOODS AND MUD SLIDES.

ah, man it didnt make it!!! at least we got .0000001 added to the ACE.

Guess what ROCK,TD's don't count for ACE units.

Could someone please post a visible picture between 12:00 UTC and 15:00 UTC of this depression while it was at its peak? I was not at home, so I didn't see the depression at its maximum strength. Thanks.

[CrazyC83]

I'm thinking it became a TD at 0600Z or so based on satellite imagery, probably 25 kt then and 30 kt at 1200Z and 1800Z (landfall). No evidence at all it became a TS.

When this became a TD for the first time, I went to its floater page and this came up. Its probably one of the funniest glitches because its wrong plus 99L becoming 99L? Here's the good part though, after 5 seconds it would keep looping back to this page and it would never stop .

About TD8, I don't think the NHC should have called this IMO. It was 20% that morning and then a TD by 2:00 pm?
