NEAR EQUATORIAL TROUGH...
THE NEAR-EQUATORIAL TROUGH HAS RETREATED WESTWARD SIGNIFICANTLY,

THIS TROUGH IS EXPECTED TO RETREAT WEST OF MICRONESIA WITHIN THE
NEXT COUPLE OF DAYS.
TRADE-WIND TROUGHS...
A TRADE-WIND TROUGH STRETCHES FROM EQ136E TO 8N135E. ANOTHER
TRADE-WIND TROUGH EXTENDS FROM 1N150E TO 20N150E. AN AREA OF
CONVERGENCE BETWEEN THE TWO TROUGHS IS CREATING SCATTERED SHOWERS AND
ISOLATED THUNDERSTORMS SOUTHEAST OF YAP AND SOUTHWEST OF CHUUK. BOTH
TROUGHS ARE EXPECTED TO MOVE WESTWARD WITH LITTLE CHANGE IN INTENSITY.
TRADE-WIND SURGE...
A TRADE-WIND SURGE COVERS POHNPEI AND KOSRAE STATES AND MOST OF THE
