A MONSOON TROUGH EXTENDS FROM 15N130E TO A WEAK CIRCULATION NEAR
12N147E THEN EAST-SOUTHEASTWARD TO 8N167E WHERE IT MEETS WITH A
SURFACE TROUGH WHICH CONTINUES TO THE EQUATOR AT 177E. SCATTERED
SHOWERS AND ISOLATED THUNDERSTORMS ARE FOUND IN THREE AREAS. THE
FIRST IS BETWEEN 9N AND 14N FROM 130E TO 144E WHICH INCLUDES
NORTHERN PORTIONS OF YAP STATE. THE SECOND IS BETWEEN 7N AND 11N

NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS ARE FOUND BETWEEN 11N
AND 16N FROM 143E TO 148E WHICH INCLUDES THE MARIANAS. THE SHOWERS
AND THUNDERSTORMS ARE BEING ENHANCED BY A COMBINATION OF THE POORLY
ORGANIZED CIRCULATION AND AN UPPER-LEVEL LOW NEAR 25N147E. THE
UPPER-LEVEL LOW IS ALSO CREATING SCATTERED SHOWERS AND ISOLATED
THUNDERSTORMS NORTH OF POHNPEI WITHIN 60 MILES OF A LINE FROM
