0330 UTC.

...TROPICAL WAVES...

TROPICAL WAVE OVER PANAMA ALONG 81W/82W N OF 7N TO THE PANAMA 
COAST AND EXTENDING N INTO WESTERN CARIBBEAN MOVING W AT 10 TO 
15 KT. SCATTERED MODERATE ISOLATED STRONG CONVECTION HAS MOVED 
OFF THE COAST OF PANAMA AND IS WEAKENING WITH TIME. WEAK 
DIFFLUENT UPPER FLOW IS EXPECTED TO TRACK W WITH THE WAVE ON THE 
SOUTHEASTERN SIDE OF THE UPPER LOW CURRENTLY NEAR 15N78W. THIS 
LOW IS EXPECTED TO MOVE WWD OVER HONDURAS OVER THE NEXT 24 HOURS.

TROPICAL WAVE OVER THE GULF OF TEHUANTEPEC AND BAY OF CAMPECHE 
ALONG 98W AND N OF 6N MOVING W AT 10 TO 15 KT. DEEP CONVECTION 
ASSOCIATED WITH MODERATELY DIFFLUENT FLOW ALOFT ACCOMPANIES THE 
S EDGE OF THE TROPICAL WAVE...WITH SHOWERS AND SCATTERED 
THUNDERSTORMS GENERALLY N OF 10N BETWEEN 92W AND 105W.

...ITCZ...
ITCZ AXIS 07N78W TO 06N85W TO 16N97W TO 07N128W TO 10N140W. 
SCATTERED MODERATE FROM 02N TO 08N E OF 89W. SCATTERED MODERATE 
ISOLATED STRONG FROM 10N TO 15N BETWEEN 90W AND 107W. 

...DISCUSSION...
STRONG NORTHERLY FLOW AT THE SURFACE IS WEDGED BETWEEN THE DEEP 
ANTICYCLONE OVER THE NORTHEAST PACIFIC CENTERED NEAR 35N132W AND 
DEEP LAYER TROUGHING OVER THE NORTHERN BAJA PENINSULA. AN UPPER 
LEVEL LOW HAS PINCHED OFF NEAR 25N120W AND IS DRIFTING W. THIS
HAS FORCED THE ANTICYCLONE NORTHWARD AND SLACKENING THE WINDS AT 
THE SURFACE OVER THE REGION...BUT CONTINUED STRONG N FLOW 
BETWEEN THE SURFACE HIGH PRESSURE AND THE PACIFIC NORTHWEST 
COAST SHOULD CONTINUE TO BRING NORTHERLY SWELLS TO 10 FT TO MUCH 
OF THE REGION N OF 15N TOMORROW.  CONVERGENT FLOW ALOFT 
PRODUCING MODERATE TO STRONG SUBSIDENCE IN MOST OF REGION 
NORTHEAST OF 13N115W.

THE REMNANTS OF DOUGLAS CONTINUE TO DIRECT SURFACE FLOW 
CYCLONICALLY CENTERED AROUND THE REMNANT LOW LEVEL CENTER NOW 
LOCATED NEAR 19N115W. THE REMNANTS REMAIN DEVOID OF DEEP 
CONVECTION. HOWEVER...THE SYSTEM IS EXPECTED TO LINGER OVER THE 
REGION OVER THE NEXT 36 TO 48 HOURS.

THE REMNANTS OF TROPICAL DEPRESSION FIVE-E CONTINUES TO TRIGGER 
SCATTERED CONVECTION MAINLY ALONG THE IMMEDIATE MEXICAN COAST 
AND JUST INLAND GENERALLY BETWEEN 21N AND 24N AND BETWEEN 105W 
AND 108W.  THE LOW LEVEL CENTER WITH THIS SYSTEM IS ONSHORE AND 
SHOULD CONTINUE TO WEAKEN AND DISSIPATE WITHIN THE NEXT 6 TO 12 
HOURS.
