THROUGH 1015 UTC.

...THE ITCZ...

FROM COASTAL GUINEA NEAR 10N14W 4N25W TO 1N40W...INTO EXTREME 
NORTHEASTERN BRAZIL NEAR 2N51W. STRONG RAINSHOWERS AND

UPPER LEVEL CYCLONIC FLOW COVERS THE GULF OF MEXICO TO THE EAST 
OF 90W...IN THE CARIBBEAN SEA TO THE NORTH OF 15N TO THE WEST OF 
THE WINDWARD PASSAGE...AND IN THE ATLANTIC OCEAN TO THE WEST OF
74W. AN UPPER LEVEL CYCLONIC CIRCULATION CENTER IS NEAR 23N77W 
IN THE WATERS BETWEEN THE BAHAMAS AND CUBA. SCATTERED MODERATE 
RAINSHOWERS TO ISOLATED STRONG THUNDERSTORMS ARE IN THE 
CARIBBEAN SEA FROM 13N TO 17N BETWEEN 76W AND 79W...TO THE

THE REST OF THE ATLANTIC OCEAN THAT IS TO THE EAST OF 60W...

AN UPPER LEVEL CYCLONIC CIRCULATION CENTER IS NEAR 28N48W.
BROAD CYCLONIC FLOW COVERS THE AREA THAT IS TO THE NORTH OF 15N 
BETWEEN 40W AND 55W. AN UPPER LEVEL RIDGE IS ALONG 68W FROM THE 
MONA PASSAGE NORTHWARD. THE ANTICYCLONIC FLOW THAT IS MOVING 
AROUND THE RIDGE THAT SPANS THE AREA THAT IS BETWEEN 56W AND 
80W. A 1009 MB LOW PRESSURE CENTER IS NEAR 27N55W. ONE SURFACE 
TROUGH CURVES AWAY FROM THE LOW CENTER TO 28N48W 26N47W 21N50W
AND 19N62W. A SECOND SURFACE TROUGH ALSO CURVES AWAY FROM THE

THE NORTH OF 15N BETWEEN AFRICA AND 40W. A CYCLONIC CIRCULATION 
CENTER IS NEAR 31N21W. ANY DEEP CONVECTIVE PRECIPITATION THAT 
ACCOMPANIES THIS FEATURE IS ALONG AND TO THE NORTH OF 31N/32N.
A 1011 MB LOW PRESSURE CENTER IS NEAR 32N18W. A COLD FRONT 
EMANATES FROM THE LOW CENTER AND EVENTUALLY PASSES THROUGH
32N12W...TO THE CANARY ISLANDS AND 26N18W. SURFACE ANTICYCLONIC 
FLOW COVERS THE AREA TO THE NORTH OF 12N BETWEEN AFRICA AND 
45W...MOVING AROUND A 33W/34W RIDGE THAT EXTENDS FROM 10N
