有個小錯誤,其實那是JMA06Z時的天氣圖,12ZJMA已經連低壓都撤了,JMA天氣圖時間(UTC)位於左上角

感謝提醒，已經修改為正確時間^^

JMA 06Z減弱為低壓，已登陸民答那峨。

LOW PRESSURE AREA 1008 HPA NEAR 06N 123E WEST 10 KT

JTWC 06Z發FW,接近菲中群島，逐漸消散。

REMARKS:
180900Z POSITION NEAR 6.6N 127.9E.
TROPICAL DEPRESSION (TD) 03W (THREE), LOCATED APPROXIMATELY 170 NM
EAST OF DAVAO, PHILIPPINES, HAS TRACKED WESTWARD AT 16 KNOTS OVER
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS A
DISORGANIZED SYSTEM WITH A SMALL AREA OF FRAGMENTED CONVECTION
SHEARED NORTHWESTWARD OF A RAGGED, EXPOSED, AND ILL-DEFINED
CIRCULATION. A 180121Z DIRECT ASCAT PASS INDICATES THE LOW LEVEL
CIRCULATION HAS UNRAVELED AND OPENED INTO A WAVE/INVERTED TROUGH. THE
SAME ASCAT IMAGERY AND AGENCY DVORAK ESTIMATES FROM PGTW AND RJTD
INDICATE THE TD HAS WEAKENED TO BELOW JTWC WARNING CRITERIA AND IS
NOT EXPECTED TO RECOVER AS IT TRACKS WESTWARD IN THE PHILIPPINE SEA
UNDER INCREASING VERTICAL WIND SHEAR. ADDITIONALLY, BY TAU 12, THE
SYSTEM WILL MAKE LANDFALL IN THE SOUTHERN PHILIPPINE ISLAND OF
MINDANAO NEAR DAVAO LEADING TO ITS FURTHER EROSION. HOWEVER, THE
SHEARED CONVECTION WILL STILL BRING NUMEROUS THUNDERSTORMS AND LARGE
AMOUNTS OF PRECIPITATION THAT CAN TRIGGER GUSTY WIND CONDITIONS AND
FLASH FLOODING OVER SOUTHERN MINDANAO. THIS IS THE FINAL WARNING ON
THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 180600Z IS 10 FEET.//
