BASED ON 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0300 UTC.

...ITCZ...
INTERTROPICAL CONVERGENCE ZONE IS CENTERED ALONG...08N80W TO 
07N85W TO 10N96W TO 06N106W TO 10N128W TO 07N140W. CLUSTERS OF 
SCATTERED MODERATE TO STRONG CONVECTION ARE FROM 03N TO 10N 
BETWEEN 98W AND 104W. SCATTERED MODERATE TO ISOLATED STRONG 
CONVECTION IS WITHIN 150/175 NM OF ITCZ FROM 85W TO 89W AND FROM 
05N TO 09N BETWEEN 124W TO 130W. CLUSTERS OF SCATTERED MODERATE 
CONVECTION ARE FROM 02N TO 07N BETWEEN 82W AND 108W.

...DISCUSSION...
E OF 110W...
FRESH TO STRONG EASTERLY WINDS ACROSS THE CARIBBEAN ARE 
GENERATING GAP WINDS OF UP TO 20 KNOTS IN THE GULF OF PAPAGAYO 
REGION. UPPER RIDGE ANCHORED OVER NICARAGUA WITH THE RIDGE AXIS 
EXTENDING W TO 110W IS PROVIDING DIFFLUENCE ALOFT TO ENHANCE THE 
CONVECTION WITHIN THE ITCZ. A SURFACE TROUGH IS EMBEDDED WITHIN 
THE ITCZ FROM 10N100W TO 04N104W FURTHER ENHANCING THE 
CONVECTION IN THE VICINITY OF THE TROUGH AXIS. 

W OF 110W...
AN ELONGATED UPPER LOW IS OFF THE W COAST OF BAJA NEAR 25N115W 
MOVING NW ALONG THE BAJA COAST BUT IS EMBEDDED WITHIN MODERATE 
TO STRONG SUBSIDENCE AND DRY AIR. AN UPPER RIDGE ANCHORED SW OF 
THE AREA COVERS THE SW PORTION OF THE REGION PROVIDING 
DIFFLUENCE ALOFT TO ENHANCE THE CONVECTION WITHIN THE ITCZ W OF 
124W. A SURFACE TROUGH IS EMBEDDED WITHIN THE ITCZ FROM 11N122W 
TO 05N126W FURTHER ENHANCING THE CONVECTION MAINLY W OF THE 
TROUGH AXIS. A SURFACE RIDGE EXTENDS FROM A 1035 MB HIGH NW OF 
THE REGION NEAR 42N145W WITH THE RIDGE AXIS EXTENDING SE THROUGH 
32N134W TO A WEAK 1014 MB HIGH NEAR 21N116W. FRESH TO STRONG

PORTION OF THE REGION. 

FRESH TO STRONG WINDS ARE ALSO S OF THE REGION AND ARE PUSHING 
SWELLS N ACROSS THE EQUATOR OVER A GOOD PORTION OF THE AREA S OF 
10N.
