Thursday Update: Hurricane Dorian moving northwest, may impact Florida this weekend

Despite interacting with the Greater Antilles Wednesday, including the island of Puerto Rico, Dorian strengthened from a tropical storm to a hurricane, and it is now moving into the open waters of the Atlantic Ocean this afternoon.

Over the next several days, Dorian will remain south of a high pressure system anchored over the Eastern Seaboard of the U.S. This high will steer Dorian further west, in the direction of the Florida Peninsula and it may make landfall as a major Category 3 hurricane with wind speeds as high as 110 – 129 mph somewhere along the east coast of Florida.

Dorian may then continue west into the Gulf of Mexico, however it is too soon to know the exact timing and location of Dorian’s path in the Gulf.

Anyone with family, friends, or travel interests in Florida, the Georgia Coastline, and the Gulf Coast should continue to monitor the path and strength of Dorian over the next several days. The interactive map above will allow you to see how Dorian’s forecast path may impact regions of interest to you.

Below is additional information from the National Hurricane Center.

DISCUSSION AND OUTLOOK
----------------------
At 1100 AM AST (1500 UTC), the center of Hurricane Dorian was
located near latitude 21.4 North, longitude 67.2 West. Dorian is
moving toward the northwest near 13 mph (20 km/h), and this general
motion is expected to continue through Friday.  A west-northwestward
motion is forecast to begin by Friday night and continue into the
weekend.  On this track, Dorian should move over the Atlantic well
east of the southeastern and central Bahamas today and on Friday,
approach the northwestern Bahamas Saturday, and move near or over
portions of the northwest Bahamas on Sunday.

Maximum sustained winds are near 85 mph (140 km/h) with higher
gusts.  Strengthening is forecast during the next few days, and
Dorian is expected to become a major hurricane on Friday, and remain
an extremely dangerous hurricane through the weekend.

Hurricane-force winds extend outward up to 15 miles (30 km) from the
center and tropical-storm-force winds extend outward up to 90 miles
(150 km).

The minimum central pressure based on data from a NOAA Hurricane
Hunter aircraft is 986 mb (29.12 inches).



HAZARDS AFFECTING LAND
----------------------
RAINFALL:  Dorian is expected to produce the following rainfall
accumulations this weekend into early next week:

The central Bahamas...1 to 2 inches, isolated 4 inches.
The northwestern Bahamas...3 to 6 inches, isolated 8 inches.
Coastal sections of the Southeast United States...4 to 8 inches,
isolated 12 inches.

This rainfall may cause life-threatening flash floods.

SURF:  Swells around the U.S. and British Virgin Islands and
Puerto Rico should gradually diminish today.  Swells are likely to
begin affecting the east-facing shores of the Bahamas and the
southeastern United States coast during the next few days.  These
swells are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
