瑪麗亞傭有2017年最頂級的風眼 .

瑪莉亞颶風登陸波多黎各







洪水的其中地方之一 , Ciales的影像釋出 .  約6米

今年的熱帶氣旋壽命很長。

諾盧 、艾瑪、荷西、瑪麗亞。

瑪麗亞颶風一次顛峰










瑪麗亞颶風二次巔峰











瑪麗亞拿兩張的巔峰主要是因為，一顛峰像1992蓋伊。
瑪麗亞的一顛峰其實潛力更好，是針眼實測140Kts的，但正好登陸了多米尼克。

雖然後來整體強度都不如二顛的小眼，但是一顛很有氣勢。如果不是因為風眼登陸了多米尼克島。
或許瑪麗亞的真實強度更強，可不輸給艾瑪。
瑪麗亞的modis是深藍眼(莫蘭蒂風眼的等級).
從針眼至小眼.
另外我發現瑪麗亞很像2013利奇馬 針眼至小眼 (同樣modis也是深藍眼與瑪麗亞同個等級)
或許利奇馬也是個150Kts+
波多黎各的風暴潮錯誤已確定. 但也很驚人 (13米!!!)




波多黎各在Palomas的79呎已經證實是錯誤的,  79呎=24米 (這是311地震大海嘯的等級....)
證實是虛驚一場。

最高的紀錄是Cidia的42呎. 約13米~而首都聖胡安是12呎(3米). 而其中一個影片Toa Baja地方也有達到8米.


近年的風暴潮紀錄

2017 颶風-瑪麗亞   13米
2005 颶風-卡翠娜     8米
2013 颱風-海燕         7米

總之無論如何，波多黎各經濟困難。災後重建恐怕不是很容易。

從命名到現在已經達13天
將持續朝東北前進

中心在北卡東方外海，準備再轉向衝向愛爾蘭。

Tropical Storm Maria Discussion Number  44
NWS National Hurricane Center Miami FL       AL152017
1100 PM EDT Tue Sep 26 2017

Practically all of the deep convection associated with Maria is
over the eastern semicircle of the circulation, and the center is
exposed near the edge of the dense overcast due to moderate
west-northwesterly shear.  SFMR-observed surface winds from an Air
Force Hurricane Hunter aircraft support a current intensity of 60
kt, although satellite classifications indicate a much weaker
cyclone.  Since SSTs are not expected to cool significantly along
the projected path of Maria over the next couple of days, only
slight weakening is forecast up to 72 hours.  Later in the forecast
period, the global models depict the cyclone as embedded in a
frontal zone, so the system is forecast to become extratropical by
day 4.

Maria continues to move slowly northward along the western periphery
of a subtropical ridge.  In 24-48 hours, the mid-latitude
westerlies should shift southward in association with a broad
mid-tropospheric trough moving across eastern North America.  This
should cause Maria to turn east-northeastward and then accelerate
ahead of the trough by late in the week.  The track models are in
general agreement on this scenario, however, the guidance has
become less tightly clustered.  This is especially true later
in the forecast period, where the ECMWF is much slower than the GFS
and HWRF models.  The official track forecast lies between these
options and is a little to the left of the previous one in the
early part of the period, in deference to the ECMWF solution.


KEY MESSAGES:

1. Maria is forecast to move roughly parallel to the U.S. east coast
for the next day or so, bringing some direct impacts to portions of
the North Carolina coast through Wednesday where a tropical storm
warning is in effect.

2. Storm surge flooding, especially along the sound side of the
North Carolina Outer Banks, is expected, and a storm surge warning
and watch are in effect for portions of eastern North Carolina.

3. Swells generated by Maria are affecting much of the east coast of
the United States.  These swells are also affecting Bermuda, the
Turks and Caicos Islands, and the Bahamas.  These swells are likely
to cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office for more
information.

NNNN

登陸波多黎各後，風切已經增強，加上艾瑪經過因素。環境不如以往，現在只剩Cat.2







另外李也Cat.1了，今年大西洋颶風很強。

仍是個C3，開始轉北進行，大概就複製Jose的路徑沿著西經72度附近北上。

Hurricane Maria Discussion Number  29
NWS National Hurricane Center Miami FL       AL152017
500 AM EDT Sat Sep 23 2017

Maria is sending mixed signals regarding its intensity this
morning.  One one side, the 35 n mi wide eye has become better
defined in satellite imagery, and the last report from an Air Force
Reserve Hurricane Hunter aircraft indicated that the central
pressure had fallen to 952 mb.  On the other side, the
aircraft-reported winds decreased a little since the previous
advisory, with maximum 700-mb flight-level winds of 110 kt and
maximum surface wind estimates from the Stepped Frequency Microwave
Radiometer near 100 kt.  Based on the aircraft winds, the initial
intensity is lowered to 105 kt.  Various analyses show that Maria is
experiencing about 15 kt of southwesterly shear, which is likely the
reason for an asymmetric distribution of convection in the eyewall
at this time.

The hurricane is likely to stay over warm water in an environment
of light to moderate shear for the next 36-48 h.  The intensity
forecast during this time will show some fluctuations in strength,
with the forecast lying near the upper edge of the intensity
guidance.  After 48 h, the forecast track takes Maria over the cold
sea surface temperatures left behind by former hurricane Jose,
which are below 26C in some areas.  This should cause a pronounced
weakening, and the new forecast is similar to the old forecast
in showing such a trend during this time.

The initial motion remains 345/8.  Maria is currently being steered
by a subtropical ridge to the east of the hurricane and a mid- to
upper-level trough over the southeastern United States.  This
combination should cause a north-northwestward to northward motion
for the next couple of days. After that, the ridge is forecast to
amplify toward the northwest due to the influence of a mid- to
upper-level ridge in the westerlies moving through the northeastern
United States.  The track guidance has responded to this evolution
by shifting westward since the last advisory, with several of the
global models now calling for Maria to come close enough to the
U. S. east coast to cause direct impacts before the system recurves
into the westerlies around 120 h. The latter part of the forecast
track is also shifted to the west, but it lies to the east of the
consensus models and the center of the guidance envelope.  If the
current model trends continue, additional westward adjustments to
the track forecast will be necessary later today.


KEY MESSAGES:

1. Swells from Maria are expected to increase along the coast of
the southeastern United States and will likely cause dangerous surf
and life-threatening rip currents for the next several days.

3. Maria will likely move between the east coast of the United
States and Bermuda by the middle of next week.  While the forecast
track has moved closer to the U. S. east coast, it is still too soon
to determine what, if any, direct impacts there might be in these
areas.

4. For more information on the flooding and rip current hazards in
the United States, please monitor information from your local
National Weather Service forecast office at www.weather.gov.
