TROPICAL WEATHER OUTLOOK
NWS NATIONAL HURRICANE CENTER MIAMI FL
800 AM EDT THU SEP 18 2014

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Hurricane
Edouard, located about 900 miles west of the western Azores.

A tropical wave, accompanied by a broad low pressure system, is
located just off of the west coast of Africa. Although shower and
thunderstorm activity remains disorganized, environmental conditions
are expected to be at least marginally conducive for some gradual
development of this system over the next several days while it moves
slowly west-northwestward to northwestward over the far eastern
tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.

HURRICANE EDOUARD DISCUSSION NUMBER  28
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL062014
500 AM AST THU SEP 18 2014

An 0426 UTC GCOM microwave pass showed that Edouard has a small,
solid inner eyewall surrounded by a thinning outer ring of deep
convection.  The infrared satellite presentation has not changed
appreciably from 6 hours ago, and the initial intensity is held at
75 kt based on a blend of Dvorak estimates from TAFB, SAB, and the
UW-CIMSS ADT.  Edouard is over 24C water, but there is still some
atmospheric instability available for the hurricane to maintain its
convective structure.  However, the SHIPS guidance shows the
instability decreasing and westerly vertical shear increasing over
30 kt during the next 24 hours, so Edouard is expected to begin a
faster weakening trend later today.  The hostile conditions should
cause Edouard to lose all of its deep convection in 36-48 hours,
and the official forecast still calls for the system to be a
post-tropical low in 48 hours and dissipate by day 5.  The NHC
forecast is just an update of the previous one and closely follows
the ICON intensity consensus.

The hurricane appears to be slowing down just a little bit and has
an initial motion of 065/24 kt.  Edouard is moving around the
northern side of a mid-tropospheric high located over the central
Atlantic, and it is forecast to turn eastward and then
southeastward
around this feature during the next 3 days.  Most of the track
models are in good agreement on this scenario.  The two main
outliers are the UKMET, which shows a sharper southward turn after
12 hours, and the GFDL, which shows Edouard continuing to race
northeastward ahead of a cold front.  The updated NHC track
forecast
is close to a consensus of the GFS, ECMWF, and HWRF models and is a
little south and west of the previous forecast after 48 hours.
