Disturbance fizzeled in Eastern Atlantic

[floridasun78]

it now off the map no yellow circle

[SouthFloridawx]

Not that it's a huge inhibiting factor, but there is a large area of SAL/Dry air to the north of the system. We're getting closer to that time of the year.

[wxman57]

This disturbance is doing the opposite of developing. It's losing convection and organization as it tracks west.Time to look elsewhere for Ana. Maybe next week.

[caribepr]

Hopefully Ana is in a land far, far away and doesn't want to travel.

I think the time has arrived for this thread to die down the pages.

Sidebar=Any member can make a new thread for another system in the Eastern Atlantic.

The Atlantic is quiet. An area of low pressure in the Central Atlantic that was being monitored for development lost much of its thunderstorm activity during the early morning hours of Wednesday. http://www.weather.com/newscenter/hurricanecentral/update/index.html?from=hp_news

TROPICAL WEATHER DISCUSSION FOR NORTH AMERICA...CENTRAL
AMERICA...GULF OF MEXICO...CARIBBEAN SEA...NORTHERN SECTIONS
OF SOUTH AMERICA...AND ATLANTIC OCEAN TO THE AFRICAN COAST
FROM THE EQUATOR TO 32N. THE FOLLOWING INFORMATION IS BASED
ON SATELLITE IMAGERY...METEOROLOGICAL ANALYSIS...WEATHER
OBSERVATIONS...AND RADAR.

BASED ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY
THROUGH 1015 UTC.

...TROPICAL WAVES...

AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 25W TO THE SOUTH OF 16N
MOVING WESTWARD 10 KT. ISOLATED MODERATE SHOWERS FROM 9N TO 15N
BETWEEN 25W AND 30W.

A 1012 MB LOW PRESSURE CENTER IS NEAR 11N33W...MOVING NORTHWEST
15 KT. SHOWERS AND THUNDERSTORMS FROM 12N TO 13N BETWEEN 32W AND
35W.

AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 38W/39W TO THE SOUTH
OF 18N MOVING WEST 15 KT. NO DEEP CONVECTIVE PRECIPITATION.
THIS WAVE HAS BEEN ADJUSTED ACCORDING TO WHAT WE DISCOVERED
24 HOURS AGO.

AN ATLANTIC OCEAN TROPICAL WAVE IS ALONG 18N58W 7N56W MOVING
WEST 15 TO 20 KT. ISOLATED MODERATE SHOWERS FROM 12N TO 14N
BETWEEN 53W AND 60W.

WHAT USED TO BE THE NORTHERN PART OF THE NOW 18N58W-7N56W
TROPICAL WAVE IS A TROUGH ALONG 18N61W 25N63W. THIS SURFACE
TROUGH IS MOVING THROUGH AN UPPER LEVEL TROUGH. IT IS NOT EASY
TO DETERMINE WHICH FEATURE IS MORE RESPONSIBLE FOR AIDING THE
DEVELOPMENT OF ANY NEARBY CONVECTIVE PRECIPITATION.

THE 74W/75W TROPICAL WAVE FROM SIX HOURS AGO HAS BEEN DROPPED
FROM THE ANALYSIS BECAUSE OF LACK OF DATA SUPPORTING ITS
EXISTENCE.

...THE ITCZ...

FROM THE AFRICA COAST NEAR 12N16W TO 9N26W 8N37W INTO
NORTHEASTERN VENEZUELA NEAR 9N63W. ISOLATED MODERATE SHOWERS
ELSEWHERE FROM 7N TO 14N BETWEEN AFRICA AND 42W.

I was not going to reply as I said,the thread has to die,but any member can make a new thread about a new wave emerging Africa today.

[somethingfunny]

That was a very prolonged poof. Any pro-mets care to explain what exactly that thunderstorm complex was, if it wasn't a low pressure center or a wave?

There were enough surface obs around the system to conclude that it wasn't a surface low center, and it wasn't a tropical wave axis. It appeared to be a mid-level feature located between two tropical waves, actually in the ridge axis. Such features generally move W-WSW and die.

Oh, and one more thing:

[cycloneye]

After Jims appearance here,its time to move on to better waves that will emerge Africa.Lets let this thread die as it wont be locked like if there is a invest.

[Frank2]

Yep, the Perfect Season was in danger of being lost, but the opposing team fumbled at the 10 yard line (dry air and shear, which is very strong at this time across the Caribbean)...

We'll see what happens this month...

[dolebot_Broward_NW]

Aye, poof.

[tolakram]

Ok, that one went poof, but what about the area behind it?

MIMIC-TWP


http://www.ssd.noaa.gov/goes/east/tatl/flash-avn.html

Some convection firing near the swirl that appears to be moving further away from the ITCZ.

The negatives?

Shear is very high just north of the current location:

[Sanibel]

Even the surface spiral evaporated. No re-burst from this.

My guess is the easterly shear and synoptic shear pushed the upper well west of the wave axis. It had a nice little pocket of favorability just off Africa but was then dessicated to death by the dry hand of subsidence and SAL which is obviously still well in place in the mid-Atlantic.

The August 16th formation date of Andrew is still open to possibility, but even that looks threatened due to the negative conditions that are obviously still out there in the Cape Verde belt.

Possible a circulation is starting to regenerate near 11.5N/36W?

This could be a threat to Hawai'i in less than 3 weeks.
