NHC : 40%

1. A broad area of low pressure centered near the northeastern coast
of Honduras is drifting northwestward and producing disorganized
shower and thunderstorm activity from Central America
east-northeastward across the Western Caribbean to Hispaniola.
Although strong winds aloft persist just to the north of the
system, the upper-level environment is expected to be conducive
enough to allow slow development.  A tropical depression could
form by late this weekend or early next week over the northwestern
Caribbean Sea or Gulf of Mexico while the system moves northwestward
to northward.  Regardless of tropical cyclone formation, this
disturbance will continue to bring torrential rains primarily to
portions of Central America and the Yucatan peninsula during the
next few days.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...high...70 percent.

iCyclone 追風團隊在Michael登陸期間
在兩個地點所記錄到的氣壓變化

原文:

During #MICHAEL, I collected quality-controlled data from 2 locations inside #hurricane's inner core. POINT A went through eye; POINT B (just 3.7 n mi to NW) stayed in inner eyewall, without ever having calm. Differences between data from these 2 points are fascinating.

麥可颶風 風眼裏面的樣子
台灣的山太高了 颱風還沒登陸颱風眼就毀得差不多了
這景象 台灣本島應該沒那麼容 ...

有，不過那是1996年強颱賀伯晚間登陸宜蘭時，我有見過朦朧的星光。另外就是1994年中颱葛拉絲中午登陸蘇澳十，不過很奇妙的是，眼牆的底層往上凹陷，高層卷積雲蓋住高層眼牆。

麥可爾颶風登陸美國成為21世紀威力最強的颶風

陸上實測 :  920.2hPa  135Kts  (近岸爆發巔峰登陸)

The Labor Day Hurricane was the most intense storm ever known to have struck the United States (and any land areas in the Western Hemisphere), having the lowest sea level pressure ever recorded in the United States—a central pressure of 892 mbar (26.35 inHg)—suggesting an intensity of between 162 kn and 164 kn (186.4 mph – 188.7 mph). The somewhat compensating effects of a slow (7 kn, 8.1 mph) translational velocity along with an extremely tiny radius of maximum wind (5 nmi, 9.3 miles) led to an analyzed intensity at landfall of 160 kt (184.1 mph, Category 5). This is the highest intensity for a U.S. landfalling hurricane in HURDAT2, as 1969's Hurricane Camille has been recently reanalyzed to have the second highest landfalling intensity with 150 kn (172.6 mph).
