8AM Advisory: Dorian Strengthens but Florida Outlook Improves

At 8AM, Category 4 Hurricane Dorian strengthens to 145 mph but there's been a positive change overnight to the forecast of Dorian as the storm veered north and potentially away from the Florida coastlines.

Southern Miami-Dade County including Miami and the Florida Keys are no longer in the cone of uncertainty. Broward and Palm Beach Counties remain in the cone.

The Bahamas are currently bracing for the Category 4 Dorian where a hurricane warning has been issued for the Northwestern Bahamas.

On its current path,the eye of Dorian should move over the Atlantic well north of the southeastern and central Bahamas today, be near or over the northwestern Bahamas tomorrow, and be near the Florida east coast late Monday.

South Florida residents can expect severe weather conditions as early as Sunday morning.

8 AM DISCUSSION AND OUTLOOK:

At 800 AM EDT (1200 UTC), the distinct eye of Hurricane Dorian

was located near latitude 25.8 North, longitude 73.0 West. Dorian is

now moving toward the west near 12 mph (19 km/h). A slower westward

motion should 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 today, be near or over the

northwestern Bahamas on Sunday, and be near the Florida east coast

late Monday.

Data from a NOAA Hurricane Hunter plane indicate that the maximum

sustained winds have increased to near 145 mph (225 km/h) with

higher gusts. Dorian is a category 4 hurricane on the Saffir-

Simpson Hurricane Wind Scale. While some fluctuations in intensity

are possible, but 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 just reported by a NOAA

Hurricane Hunter aircraft was 944 mb (27.88 inches).

HAZARDS AFFECTING LAND

----------------------

WIND: Hurricane conditions are expected in the hurricane warning

area across the northwestern Bahamas by Sunday, with tropical storm

winds beginning tonight.

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 25 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 will begin affect 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.
