Hurricane NICOLE (Text)

Hurricane Nicole Discussion Number  12
NWS National Hurricane Center Miami FL       AL172022
1000 PM EST Wed Nov 09 2022

The hurricane has large intense bands extending quite far from the 
center, but does not have a distinct Central Dense Overcast.  
Flight-level wind observations from Hurricane Hunter aircraft 
indicate that the maximum winds are near 65 kt.  Dvorak satellite 
classifications gave a slightly lower intensity, probably because 
the system does not have a classic tropical cyclone appearance at 
this time.  Nicole has a large eye over 50 nmi in diameter, and a 
very large extent of tropical-storm-force winds over its northern 

Nicole has made its expected turn toward a west-northwestward 
heading and the motion estimate is now 285/11 kt.  The system 
should turn toward the northwest and north during the next day or 
so while moving along the western side of a mid-level anticyclone, 
moving over the Florida peninsula and northern Florida.  In 36 to 
48 hours, Nicole should accelerate north-northeastward to the east 
of a longwave mid-tropospheric trough.  The official track forecast 
is about the same as the previous one and remains close to the 
multi-model consensus prediction.

The hurricane has little time to strengthen further before making 
landfall in Florida.  Weakening will occur while Nicole moves over 
Florida, and even though the center may briefly emerge over the 
extreme northeastern Gulf of Mexico, this is not likely to result in 
any significant re-intensification.  The system should weaken to a 
depression and become a post-tropical cyclone over the southeastern 
United States.  Nicole should merge with another extratropical low 
over the eastern United States after 48 hours.

Key Messages:
1. Hurricane and tropical storm conditions and a dangerous storm
surge are expected to continue over portions of the northwestern
Bahamas tonight, where a Hurricane Warning remains in effect.
2. Hurricane conditions are expected across portions of the coast
of southeast and east-central Florida tonight, where a Hurricane 
Warning is in effect.  Tropical storm conditions will continue along 
the east coast of Florida, Georgia, and South Carolina within the 
warning areas into Thursday.  Tropical storm conditions are expected 
to begin along the west coast of Florida tonight and Thursday.
3. A dangerous storm surge is expected along much of the east coast
of Florida, portions of coastal Georgia, and the Florida Big Bend
along the Gulf coast.  The storm surge will be accompanied by large
and damaging waves along the Atlantic coast.  Residents in the
warning area should listen to advice given by local officials.
4. Do not focus on the exact track of Nicole since it is a large
storm with hazards extending well to the north of the center,
outside of the forecast cone.  These hazards will affect much of the
Florida peninsula and portions of the southeast United States.
5. Nicole will produce heavy rainfall tonight into Thursday across 
the Florida Peninsula. Flash and urban flooding will be possible 
across portions of the Florida Peninsula along with renewed river 
flooding on the St. Johns River. Isolated flash, urban, and small 
stream flooding will also be possible on Friday in the Southeast 
through the southern and central Appalachians, including the Blue 
Ridge Mountains, and extending northward through west-central 
Pennsylvania into western New York by Friday night into Saturday.
