TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2205 UTC FRI MAY 30 2008

TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN
FROM THE EQUATOR TO 32N...EAST OF 140W. 

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY 
THROUGH 2130 UTC.

...TROPICAL WAVES...
.NONE.

...ITCZ...
ITCZ AXIS IS CENTERED ALONG 13N90W 10N96W 8N110W 4N130W 6N140W. 
SCATTERED MODERATE TO STRONG IS FROM 11N TO 14N BETWEEN 93W AND 
96W.  

...DISCUSSION...

E OF 100W...

ALMA DISSIPATED EARLIER TODAY OVER THE HIGH TERRAIN OF HONDURAS 
AND GUATEMALA. HOWEVER...AREAS OF HEAVY RAIN CONTINUE TO AFFECT 
PORTIONS OF CENTRAL AMERICA...ESPECIALLY OVER E NICARAGUA AND 
BELIZE. THIS ACTIVITY IS PRODUCED BY THE REMNANTS OF ALMA 
AND A BROAD AREA OF LOW PRES ASSOCIATED WITH A TROPICAL WAVE 
OVER THE NW CARIBBEAN. AN AREA OF CONVECTION HAS BEEN NEARLY 
STATIONARY OVER THE PAST SEVERAL HOURS S OF THE GULF OF 
TEHUANTEPEC FROM 11N-14N BETWEEN 93W-96W...LIKELY GENERATED  BY 
LOW-LEVEL SPEED AND DIRECTIONAL CONVERGENCE BETWEEN STRONG WINDS 
FUNNELING THROUGH TEHUANTEPEC TO THE LIGHTER FLOW ALONG THE 
ITCZ. A RECENT HI-RES ASCAT PASS REVEALED A NARROW SWATH OF 
20-25 KT IN THE GAP...BUT MODELS INDICATE THESE WINDS QUICKLY 
DIMINISHING OVER THE NEXT 12-18 HOURS OR SO.

W OF 100W...

THE LARGE SCALE PATTERN CONSISTS OF AN UPPER LOW SPINNING OFF 
THE NW CONUS STATES WITH ASSOCIATED TROUGHING EXTENDING INTO THE 
DISCUSSION AREA FROM 30N134W TO 22N140W AND A WELL DEFINED RIDGE 
PARKED OVER CENTRAL MEXICO. THIS OVERALL PATTERN IS PRODUCING 
WIDESPREAD SUBSIDENCE ACROSS NEARLY THE ENTIRE ZONE W OF 
110W...SUPPRESSING CONVECTION/DEEP CLOUDINESS ACROSS THE 
AREA...EVEN ALONG THE ITCZ. A SMALL UPPER LOW IS CENTERED NEAR 
12N106W GENERATING SCATTERED SHOWERS AND ISOLATED TSTMS WITHIN 
240 NM OF THE CENTER. AT THE SFC...A 1025 MB IS SITUATED WELL N 
OF THE AREA NEAR 46N134W. BESIDES FOR A NLY SURGE OFF THE BAJA 
COAST...WINDS REMAIN MAINLY BELOW THE 20 KT HIGH SEAS CRITERIA.
