BASED ON 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0245 UTC.

...ITCZ...
AXIS IS ALONG 05N77W TO 04.5N80W TO 06.5N87W TO 03N99W TO 
07N120W TO 04.5N140W. SCATTERED MODERATE TO STRONG CONVECTION 
WITHIN 240 NM S OF AXIS BETWEEN 83W AND 86W. SCATTERED MODERATE 
TO STRONG CONVECTION WITHIN 180 NM N OF AXIS BETWEEN 87W AND 
95W. SCATTERED MODERATE CONVECTION WITHING 150 NM N OF AXIS AND 
90 NM S OF AXIS BETWEEN 99W TO 117W. SCATTERED MODERATE ISOLATED 
STRONG CONVECTION WITHIN 240 NM S OF AXIS W OF 126W. 

...DISCUSSION...
A LARGE AMPLITUDE UPPER LEVEL TROUGH EXTENDS FROM THE N PART OF 
THE BAJA PENINSULA SW TO 11N125W. UPPER LEVEL RIDGING PREVAILS 
ACROSS THE REMAINDER OF THE AREA ON EITHER SIDE OF THE TROUGH. 
MID AND UPPER LEVEL MOISTURE FROM CONVECTION IN THE ITCZ W OF 
126W IS BEING ADVECTED NE IN THE SW FLOW ON THE E SIDE OF THE 
UPPER LEVEL TROUGH TOWARD AND OVER CENTRAL MEXICO. 

AT THE SURFACE...HIGH PRESSURE 1024 MB CENTERED NEAR 31N134W IS 
MAINTAINING FRESH TO STRONG TRADES FROM 05N TO 20N W OF 125W. 
THE STRONG TRADES ARE MAINTAINING ENOUGH MOISTURE CONVERGENCE TO 
KEEP THE ITCZ CONVECTIVELY ACTIVE W OF 126W. STRONG TO NEAR GALE 
WINDS FLOWING ACROSS THE GULF OF PAPAGAYO IS ALSO HELPING FUEL 
MOISTURE CONVERGENCE INTO THE ITCZ TO MAINTAIN CONVECTIVE 
ACTIVITY BETWEEN 83W AND 95W.

GAP WINDS
GULF OF TEHUANTEPEC WINDS HAVE DIMINISHED BELOW 20 KT. WITH THE 
COLD FRONT IN THE WESTERN CARIBBEAN REACHING NICARAGUA...WINDS 
FUNNELING INTO THE GULF OF PAPAGAYO HAVE INCREASED. WINDS ARE 
NORTHEASTERLY 20-30 KT. WINDS WILL GRADUALLY DIMINISH THROUGH  
THE FORECAST PERIOD. STRONG TRADES FROM THE CARIBBEAN ARE ALSO 
FUNNELING INTO THE GULF OF PANAMA...PRODUCING A SMALL AREA OF 20 
KT WINDS N OF 07N BETWEEN 79W AND 81W. THESE WINDS WILL MAINTAIN 
UNTIL TOMORROW NIGHT...THEN DIMINISH BELOW 20 KT.
