23 HKT, 2009/11/27 (or earlier 或更早)

NIDA underwent rapid deepening in the past 24 hours, strengthening from a severe tropical storm into a typhoon of the highest category. NIDA is also the third category 5 super typhoon in northwestern Pacific Ocean this year, and is probably the strongest among them. At 20 HKT, NIDA was centred about 300 km (160 NM) WSW of Guam.

妮妲於過去 24 小時出現爆發性增強，由強烈熱帶風暴迅速增強為颱風的最高級別。妮妲亦為本年西北太平洋內第三個五級超級颱風，並很可能為三者中最強。在 20 HKT，妮妲集結在關島西南偏西約 300 公里 (180 海里)。

NIDA is now moving NW along the southwestern periphery of the Pacific subtropical ridge. The cyclone is expected to decelerate as it nears the ridge axis, and now a recurvature is expected as it is likely that NIDA will be strong enough not to be guided by the low-level northeasterlies.

妮妲正處於副熱帶高壓脊的西南部，並向西北移動。預料妮妲將於靠近脊線時減慢；由於預測妮妲強度仍稍高，被東北季風帶動的機會較少，本佈因此預料妮妲將於稍後轉向東北移動。

Current T-number: T7.5/7.5/D4.0/30 HRS
NIDA intensified explosively in an extremely favourable environment - outflow is very good and the level of vertical wind shear is virtually nil. NIDA is expected to peak in strength very soon, and as it moves north it will encounter cooler waters which will initiate weakening.

現時的 T 號碼: T7.5/7.5/D4.0/30 HRS
妮妲於極佳的週邊環境下大幅增強，該區輻散良好而垂直風切變甚低。預料妮妲即將到達巔峰強度，其後將受較涼海水的影響而逐步減弱。

妮妲為熱帶氣旋名稱列表中第 96 個名字，由泰國提供，為一女性名字。這個名稱曾於 2004 年使用。

NIDA is expected to travel NW in the next 72 hours. However, models start to diverge after t+72, with some depicting recurvature as the ridge will not be strong enough to prevent NIDA from penetrating. This bulletin reduces the magnitude of the westward turn in the extended forecast period to reveal a greater uncertainty in NIDA's track at that time.

妮妲將於未來 72 小時向西北移動。數值模式對 72 小時後的預測路徑出現分歧，部分模式預計副熱帶高壓脊將未能大幅增強，而令妮妲繼續向西北甚至轉為北移。本佈稍為修改延伸預報期的預測，以反映該時段路徑預報的不確定性。

Current T-number: T3.5/3.5/D1.0/18 HRS
NIDA is expected to pick up strength gradually in moderate environments with low shear and warm seas. Typhoon status is imminent.

現時的 T 號碼: T3.5/3.5/D1.0/18 HRS

妮妲將於未來 48 至 72 小時向西北移動。預料副熱帶高壓脊將於三天後增強，妮妲或會在預測後期改回偏西路徑。部份模式預料妮妲跟 27W 間將發生相互影響；如此情境發生，妮妲的移動路徑將變得更為複雜。
