Marie continues to become better organized, with abundant deep
convection and banding features in all quadrants.  Additionally,
water vapor imagery shows that the upper-level outflow is becoming
increasingly well defined.  The current intensity estimate is set at
45 kt in general agreement with objective Dvorak estimates from
UW/CIMSS.  Since the tropical cyclone will be moving through an
environment of low shear and very warm waters for the next several
days, continued strengthening seems inevitable.  Marie should become
a hurricane within 24 hours and will likely attain at least Category
3 status during the forecast period.  This is suggested even by the
global models such as the GFS, which predicts that Marie will deepen
below 950 mb in a few days.  The official wind speed forecast, which
could be conservative, is based on a blend of the objective
intensity guidance.

The storm is moving west-northwestward or 290/15 kt.  The
steering/track forecast scenario appears to be straightforward at
this time.  Over the next several days, Marie should move along the
southern periphery of a mid-tropospheric subtropical ridge that will
be building westward from northern Mexico.  The dynamical track
forecast models are tightly clustered, and the official forecast is
very close to the model consensus.  This is essentially an update of
the previous NHC forecast.

NHC 21Z正報上調巔峰至115KT
強度預報與SHIPS數值模式接近

Marie continues to intensify.  Satellite images show a well-
organized cloud pattern, with considerable deep convection and
numerous rain bands surrounding the center.  The current intensity
estimate is set at 50 kt, which is based on a blend of subjective
Dvorak estimates from TAFB and SAB, ADT values from UW/CIMSS, and
data from a couple of recent ASCAT overpasses.  The tropical cyclone
will be moving over very warm waters of almost 30 deg C and vertical
shear is forecast to remain low throughout the period. Some of the
intensity guidance is very aggressive in strengthening Marie.  In
particular the SHIPS model, which shows strengthening to Category 4
status in 48 hours, and the SHIPS Rapid Intensification Index, which
shows a 59 percent chance of a 35-kt increase in winds over the next
24 hours.  The official intensity forecast is close to the SHIPS
guidance through 48 hours, and is a blend of the LGEM and SHIPS
models thereafter.

繼續上望C4 115kts

這還只是保守的上望而已.

瑪莉未來可能繼金娜薇之後最強的.

仍持續預期快速增強，但預測巔峰稍微下調。NHC 根據的是比較樂觀的模式預測，但沒有很確定，因為不同模式對未來垂直風切的趨勢有歧見。

HURRICANE MARIE DISCUSSION NUMBER 7
NWS NATIONAL HURRICANE CENTER MIAMI FL    EP132014
800 AM PDT SAT AUG 23 2014

Marie has been rapidly intensifying with a 30-kt increase since
yesterday at this time.  Symmetric, cold cloud tops are persisting
in association with the hurricane, though an eye has yet to make an
appearance.  Dvorak CI numbers are increasing, and a blend
of the ADT, SAB, and TAFB values indicate an intensity of 75 kt.
Continued intensification is expected, but how much is fairly
uncertain.  The SSTs, moisture, and convective instability are
likely to continue being very conducive for the next three days.
The GFS-based vertical shear within the SHIPS model suggests about
10-15 kt of deep-layer shear currently and gradually increasing over
next three days.  However, the CIMSS shear analysis suggests
substantially less shear now, which is more consistent with the
symmetric appearance to the convection and the observed rapid
intensification.  The forecast intensity is close to the SHIPS
statistical model through three days, which is higher than any of
the other guidance.  By days four and five, Marie should be passing
over cold waters and moving into a stable atmosphere.  The forecast
intensity at the long-lead times is close to the IVCN consensus.
This official intensity prediction is slightly below that provided
in the previous advisory from 36 hours onward.  Unfortunately, no
new size information has been available and the wind radii analysis
and prediction remain about the same.

The initial position is somewhat uncertain, due to no microwave
passes recently and no eye being seen yet.  However, the available
fixes suggest a somewhat farther northward position than earlier
analyzed.  The current motion is west-northwest at 9 kt, slightly
slower than previously. Marie is primarily being steered by a
deep-layer ridge to its northeast, which should continue being the
main steering factor for the entire forecast time.  The track
guidance is in very close agreement all the way to five days and
suggests more confidence than usual in the forecast track.  The
official track prediction is just slightly northward of the previous
advisory because of the initial shift in position, but is otherwise
quite close in longitude.
