原本不是說會北移嗎?
進入西太嗎?
現在預測朝向澳洲東北部
跨赤道可是天大的奇蹟,畫眉都甘拜下風。
現在已經是熱帶低氣壓,預測成為一級熱帶氣旋,然後登陸昆士蘭。

REMARKS:
Dvorak analysis based on a curved band pattern with 0.3 degree wrap on a log10
spiral, giving a DT of 2.0. MT and PT both suggest 2.0. FT based on MT.
The Tropical Low has developed in general over the last 24 hours while moving
over the warm sea surface of the northern Coral Sea in a low wind shear
environment. The Tropical Low is expected to continue to move within this
favourable environment for further development over the next 24 hours and it
should intensify into a tropical cyclone during Tuesday.
The Tropical Low has been moving slowly in a westwards direction over the last
12 hours and should continue to move in this direction during Tuesday under the
influence of a developing mid-level ridge across Queensland and the central
Coral Sea.
