DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Hurricane Dorian was located near latitude 25.5 North, longitude 71.4 West. Dorian is moving toward the west-northwest near 10 mph (17 km/h). A slower west-northwestward to westward motion should begin tonight and continue into early next week. On this track, the core of Dorian should move over the Atlantic well north of the southeastern and central Bahamas tonight and tomorrow, be near or over the northwestern Bahamas on Sunday, and be near the Florida east coast late Monday. Data from a NOAA Hurricane Hunter aircraft indicate that the maximum sustained winds have increased to near 140 mph (220 km/h) with higher gusts. Dorian is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some additional strengthening is possible tonight and Saturday. Although fluctuations in intensity are possible early next week, Dorian is expected to remain a powerful hurricane during the next few days. Hurricane-force winds extend outward up to 30 miles (45 km) from the center and tropical-storm-force winds extend outward up to 105 miles (165 km). The latest minimum central pressure based on data from a NOAA reconnaissance aircraft is 948 mb (28.00 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the hurricane warning area in the northwestern Bahamas by Sunday, with tropical storm winds beginning Saturday night. STORM SURGE: A life-threatening storm surge will raise water levels by as much as 10 to 15 feet above normal tide levels in areas of onshore winds in the northwestern Bahamas. Near the coast,the surge will be accompanied by large and destructive waves. RAINFALL: Dorian is expected to produce the following rainfall accumulations this weekend into the middle of next week: Northwestern Bahamas...10 to 15 inches, isolated 20 inches. Coastal sections of the southeast United States...6 to 12 inches, isolated 18 inches. Central Bahamas...2 to 4 inches, isolated 6 inches. This rainfall may cause life-threatening flash floods. SURF: Swells are likely to begin affecting the east-facing shores of the Bahamas, the Florida east coast, 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.
