On this track, Dorian should move over the Atlantic well east of the southeastern and central Bahamas tonight and on Friday, approach the northwestern Bahamas Saturday, and move near or over portions of the northwest Bahamas on Sunday. Maximum sustained winds have increased to near 105 mph (165 km/h) with higher gusts. 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 25 miles (35 km) from the center, and tropical-storm-force winds extend outward up to 105 miles (165 km). The latest minimum central pressure estimated from Hurricane Hunter data is 977 mb (28.85 inches).

The northwestern Bahamas...3 to 5 inches, isolated 7 inches. Coastal sections of the Southeast United States...5 to 10 inches, isolated 15 inches. This rainfall may cause life-threatening flash floods. SURF: 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.
