Hurricane Dorian projected to take to take a more western path across the state
The cloud pattern has become better organized with a hint of an eye
on high resolution satellite imagery and plenty of convective bands.
In addition, earlier data from a reconnaissance plane and surface
observations from St. Thomas as Dorian moved by yield an initial
intensity of 70 kt.  Now that the hurricane has developed an inner
core with a 15 to 20 n mi eye, strengthening is more likely. Given
the favorable environment of warm waters and low shear prevailing in
the western Atlantic, the NHC forecast calls for a marked
intensification, and brings Dorian to category 3 intensity in 72
hours, and keeps it at that intensity until landfall. This
forecast is very close to the intensity consensus, the HCCA model,
and the SHIPS guidance.

Satellite and earlier reconnaissance plane fixes indicate that
Dorian has been moving toward the northwest or 320 degrees at 12
kt.  The cyclone is heading toward a weakness in the Atlantic
subtropical ridge, and this northwest motion should continue for the
next 24 to 48 hours. However, after that time, all the global models
continue to build a strong ridge over the western Atlantic, and this
flow pattern should force Dorian to turn more to the west-northwest
toward Florida. All indications are that by this Labor Day weekend,
a powerful hurricane will be near or over the Florida peninsula. The
new NHC track forecast is a little bit to the south of the previous
one, given that global models have a stronger ridge to the north and
the track models show more of a westward motion.  Users are reminded
not to focus on the exact forecast track, as the average 5-day track
error is around 200 miles.

Key Messages:

1. Dangerous winds will continue in the Virgin Islands, Culebra,
Vieques, and portions of Puerto Rico during the next few hours.
Heavy rainfall over portions of Puerto Rico and the Virgin Islands
could produce flash flooding through Thursday morning.

2. The risk of dangerous storm surge and hurricane-force winds later
this week and this weekend continues to increase in the central and
northwestern Bahamas and along the Florida east coast, although it
is too soon to determine where these hazards will occur. Residents
in these areas should ensure they have their hurricane plan in place
and not focus on the exact forecast track of Dorian's center.

3. Heavy rains are expected to occur over portions of the Bahamas,
Florida, and elsewhere in the southeastern United States later this
week and into early next week.
