Another Test? AL852006

[skysummit]

I looked at satellite imagery and I don't see anything there. The Discussion did mention something about a closed low at the surface, but the coordinates don't match to where these models are. Probably just another test....

From the Disco.....can't be the same thing.

...DISCUSSION...

THE GULF OF MEXICO...AND THE ATLANTIC OCEAN
NORTH OF 20N WEST OF 60W...
THE MID TO UPPER LEVEL LOW CURRENTLY OVER NEW MEXICO IS
PRODUCING 60 TO 90 KT WINDS OUT OF THE WEST AND WEST-SOUTHWEST
OVER MEXICO IN THE UPPER LEVELS. ZONAL WEST WINDS OF 50 TO 60
KT ARE FOUND IN THE UPPER LEVELS OVER THE GULF OF MEXICO ...
WHICH TURN CYCLONICALLY OVER THE WESTERN NORTH ATLANTIC BETWEEN
20N AND 30N IN RESPONSE TO THE SLOWLY MOVING DEEP LAYER LOW
SOUTH OF NOVA SCOTIA. AT THE SURFACE ... WINDS OVER THE GULF OF
MEXICO ARE PRIMARILY OUT OF THE SOUTHEAST AND ARE STRONGEST ...
UP TO 20 KT ... IN THE SOUTHWESTERN GULF. IN THE ATLANTIC A
FRONTAL BOUNDARY THAT IS BECOMING STATIONARY EXTENDS FROM 22N72W
TO 24N60W. SOUTH OF THE FRONT WINDS ARE WEAK AND DISORGANIZED
WHILE NORTH OF THE FRONT THE WINDS ARE WEAKLY FROM THE NORTH.
SOME SHOWER ACTIVITY MAY BE ASSOCIATED ALONG THE FRONT. A WEAK
NEW DISTURBANCE/CLOSED LOW HAS FORMED AT THE SURFACE NEAR 30N77W
... WHICH MAY HAVE DEVELOPED OFF OF THE WESTERN REMNANTS OF THE
FRONT ALREADY MENTIONED. NUMEROUS STRONG SHOWERS AND SOME
THUNDERSTORMS ARE WITHIN A 75 NM RADIUS OF 28N76W ... SOMEWHAT
SOUTH AND EAST OF THE WEAK CIRCULATION CENTER.

[P.K.]

85 is one of the test numbers yes.

When the storm number is 01-49... this is a tropical cyclone. 50-79 are reserved for internal use. (i.e. some runs of Cyclone Catarina were on 50L) 80-89 are for tests and exercises. 90-99 are for tropical disturbances.

Ahh...thanks for the info!

Look like shear is lowering a little because most of the other test latly they kill them in around 24 hours this on is lastin to 72hours
