MARINE WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
130 AM EDT SUN JUN 10 2007

MARINE WEATHER DISCUSSION FOR GULF OF MEXICO...CARIBBEAN SEA
AND SOUTHWEST NORTH ATLC S OF 31N W OF 55W.

A STRONG CUTOFF LOW JUST N OF THE AREA NEAR 37N62W IS BEGINNING 
TO INTERACT WITH THE NRN BRANCH OF THE WESTERLIES TONIGHT BY 
INTERCEPTING SHORTWAVES AND ROTATING THEM AROUND THE SRN 
PERIMETER OF THE CUTOFF INTO OUR AREA. THIS IS RESULTING IN 
LOWERING SURFACE PRES ALONG OUR BORDER AND INCREASING SWLY WINDS 
N OF 30N. OTHERWISE A MID LEVEL RIDGE COVERS THE NW GULF WHILE A 
WEAK MID LEVEL TROUGH SLIDES SW AROUND THE RIDGE OVER WRN CUBA 
AND THE NW CARIB. A FLAT MID LEVEL RIDGE COVERS THE TRPL ATLC S 
OF 24N E OF 75W. ON THE SURFACE TONIGHT ONE TRPL WAVE WAS NEAR 
40W ANOTHER NEAR 65W AND A THIRD ONE NEAR 75W. A STRONG WAVE WAS 
OFF THE AFRICAN COAST BUT FORECAST TO MOVE OVER COLDER WATERS 
AND NOT DEVELOP.

LATER DAY 1 WHILE THE MID LEVEL RIDGE HOLDS FIRM OVER THE NW 
GULF..THE CUTOFF BEGINS TO LIFT NNE. THE MID LEVEL TROUGH OVER 
WRN CUBA DRIFTS SW OVER THE NW CARIB. ON THE SURFACE LATER DAY 1 
SWLY WINDS OF 20 KT WILL CONTINUE N OF 30N BETWEEN 58W AND 74W. 
THE ATLC RIDGE SHOWS SIGNS OF STRENGTHENING BUT TRADES REMAIN 
LIGHT TO MODERATE. CARIB WINDS 15 TO 20 KT WHILE GULF WINDS 
MOSTLY LIGHT.

FOR DAY 2 THE NRN BRANCH CONTINUES TO SWING SE OFF THE SE COAST 
WITH A SHORTWAVE OVER THE MO VALLEY HEADING SE. LITTLE CHANGE TO 
THE MID LEVEL RIDGE OVER THE NW GULF. THE TROUGH OVER NW CARIB 
WEAKENS. THE MID LEVEL RIDGE OVER THE TRPL ATLC LOOKS BETTER. ON 
THE SURFACE DAY 2 THE ATLC RIDGE SHOWS SOME LIFE WITH A 1027 MB 
CENTER NEAR 30N40W AND TRADES INCREASE TO 20 KT. CARIB WINDS 
ALSO INCREASE SLIGHTLY E OF 80W WHILE ATLC W OF 65W AND GULF 
WINDS REMAIN LIGHT.

OUTLOOK PERIOD...

FOR DAY 3 A LARGE MID LEVEL TROUGH CONFIGURATION SETS UP MOSTLY 
N OF THE AREA BUT HAVING SOME AFFECT OVER THE SW ATLC. THE MID 
LEVEL RIDGE OVER THE NW GULF BUILDS NWD INTO THE WRN GREATLAKES 
AS STRONG TROUGHING DEVELOPS OVER THE WRN CONUS. LITTLE CHANGE 
TO THE MID LEVEL TRPL RIDGE. ON THE SURFACE DAY 3 LITTLE CHANGE 
FROM THE DAY BEFORE EXCEPT FOR A WEAK FRONT THAT SLIPS INTO ATLC 
WATERS FROM 31N63W TO 28N70W WITH WINDS TO 20 KT AHEAD OF IT. 

FOR DAY 4 THE LARGE BLOCKING TROUGH CONFIGURATION CONTINUES OVER 
THE ATLC EXTENDING BACK TO THE SE CONUS. THE MID LEVEL RIDGE 
SHOWS SIGNS OF WEAKENING AS A BUBBLE SEPARATES AND MOVES NE INTO 
SE CANADA. MID LEVEL RIDGING COVERS THE ATLC E OF 65W S OF 30N. 
ON THE SURFACE DAY 4 A 1024 MB HIGH ANCHORS THE ATLC RIDGE NEAR 
28N42W WITH MODERATE TRADES S OF 20N E OF 76W. A WEAK FRONTAL 
TROUGH DROPS S OVER THE FL PANHANDLE WITH SW WINDS OVER THE NE 
GULF PICKING UP TO 20 KT. 

FOR DAY 5 MID LEVEL HIGH PRES OVER SE CANADA PUSHES THE MID 
LEVEL TROUGH SWD OVER THE SE CONUS WITH MORE AFFECT ON OUR 
REGION. MID LEVEL HEIGHTS BEGIN TO FALL SOME OVER THE PLAINS AS 
A TROUGH MOVES E FROM THE ROCKIES. ON THE SURFACE DAY 5 LITTLE 
CHANGE TO THE ATLC RIDGE AND TRADES REMAIN ABOUT THE SAME. SOME 
FRONTAL ACTIVITY OVER THE ATLC 31N58W TO 28N65W AND OVER THE NE 
GULF BUT WINDS REMAIN MOSTLY LIGHT.
 
WARNINGS...
ATLANTIC...NONE.

CARIBBEAN...NONE.

GULF OF MEXICO...NONE.
