..OTHER WEATHER SYSTEMS
NEAR-EQUATORIAL TROUGH...
A NEAR-EQUATORIAL TROUGH (NET) ENTERS THE REGION NEAR 5N130E,
EXTENDING ENE ACROSS YAP PROPER TO A WEAK CIRCULATION SE OF YAP
PROPER, SSW OF GUAM, CENTERED NEAR 8N140E. THE NET THEN TURNS ESE
THROUGH ANOTHER WEAK CIRCULATION JUST S OF WENO, CHUUK NEAR 6N153E.
FROM HERE, THE NET STRETCHES E, PASSING JUST S OF MAJURO, TURNING SE
TO BEYOND THE DATE LINE NEAR 4N. THERE IS VERY LITTLE CLOUD COVER OR
CONVECTION ASSOCIATED WITH THE NET FOR PALAU. OVER YAP PROPER AND
FARTHER E, CONVECTION INCREASES SIGNIFICANTLY. PATCHES OF NUMEROUS TO
WIDESPREAD LOCALLY HEAVY SHOWERS AND ISOLATED THUNDERSTORMS ARE
FOUND OVER YAP PROPER TO N OF WENO, CHUUK AND POHNPEI. SCATTERED TO
NUMEROUS SHOWERS ARE FOUND N OF KOSRAE, ACROSS THE SOUTHERN MARSHALL
ISLANDS TO THE DATE LINE. THE NET LOOKS TO MEANDER N AND S OVER THE
NEXT FEW DAYS, WITH WEAK CIRCULATIONS DEVELOPING AND TRAVERSING THE
NET, PRODUCING LOCALLY HEAVY SHOWERS AND ISOLATED THUNDERSTORMS
ACROSS MOST OF MICRONESIA.
TRADE-WIND TROUGHS...
A WEAK TRADE-WIND TROUGH IS SEEN JUST E OF THE FAR NORTHERN CNMI,
EXTENDING NNE FROM NEAR 16N147E TO END NEAR 24N149E. SPOTTY CLOUDS
AND SHOWERS ARE FOUND WITH THIS TROUGH. THE TROUGH IS EXPECTED TO
MOVE W AND WEAKEN FURTHER OVER THE NEXT COUPLE OF DAYS.
ANOTHER TRADE-WIND TROUGH IS FOUND N OF THE CIRCULATION ALONG THE NET
THAT IS CENTERED JUST S OF WENO, CHUUK, EXTENDING N TO END NEAR
12N155E. THIS TROUGH IS ENHANCING CONVECTION N OF WENO. HE TROUGH
WILL CONTINUE TO MOVE W, INTERACTING WITH THE NET AS IT APPROACHES
YAP.
OTHER SYSTEMS...
A DECAYING COLD FRONT ENTERS THE REGION NEAR 25N146E, EXTENDING SE
TO END NEAR 21N137E. SPOTTY CLOUDS AND SHOWERS ARE FOUND ALONG THE
BOUNDARY. THE FRONT WILL CONTINUE TO DISSIPATE AS IT MOVES E OVER THE
NEXT COUPLE DAYS, WITH DECREASING CLOUDS AND SHOWERS.
..ITCZ
THE ITCZ THAT WAS PRESENT ACROSS FAR E MICRONESIA HAS MERGED WITH THE
NET AND IS NO LONGER DISTINGUISHABLE W OF THE DATE LINE.
