這裡已經安靜好一陣子了
結構看起來相當鬆散還有待整合
不過我反到認為風速是個亮點...
這種結構居然有35kts@@?

這樣...哪招 = =
該算是TS還是擾動呢
第一次看過這種圖 = =

根據NHC的報文
這個系統在48小時內有60%的機率
會變成一個副熱帶或熱帶氣旋
不過依這個結構個人認為比較像副熱帶氣旋

A LARGE AREA OF CLOUDINESS AND THUNDERSTORMS OVER THE CENTRAL
ATLANTIC OCEAN IS ASSOCIATED WITH A NON-TROPICAL LOW PRESSURE
SYSTEM CENTERED ABOUT 800 MILES EAST-SOUTHEAST OF BERMUDA.
SATELLITE AND SHIP DATA INDICATE THAT THIS SYSTEM IS PRODUCING GALE
FORCE WINDS.  ENVIRONMENTAL CONDITIONS ARE EXPECTED TO BE CONDUCIVE
FOR THE LOW TO ACQUIRE SUBTROPICAL OR TROPICAL CHARACTERISTICS
DURING THE NEXT COUPLE OF DAYS WHILE IT MOVES SLOWLY NORTH-
NORTHWESTWARD TO NORTHWARD.  AFTER THAT TIME...CONDITIONS ARE
FORECAST TO BECOME LESS CONDUCIVE FOR DEVELOPMENT AS THE LOW MOVES
NORTH-NORTHEASTWARD TOWARD THE NORTH ATLANTIC. THIS SYSTEM HAS A
HIGH CHANCE...60 PERCENT...OF BECOMING A SUBTROPICAL OR TROPICAL
CYCLONE DURING THE NEXT 48 HOURS....AND A HIGH CHANCE...
70 PERCENT...OF BECOMING A SUBTROPICAL OR TROPICAL CYCLONE DURING
THE NEXT 5 DAYS.  ADDITIONAL INFORMATION ON THIS SYSTEM CAN BE
FOUND IN HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER
SERVICE.
