Issued at 500 PM EDT Sat Aug 31 2019 000 WTNT45 KNHC 312052 TCDAT5 Hurricane Dorian Discussion Number 30 NWS National Hurricane Center Miami FL AL052019 500 PM EDT Sat Aug 31 2019 Dorian's satellite presentation continues to be outstanding. The eye has remained very distinct and is surrounded by a ring of very deep convection. The latest information from the Air Force plane before it departed Dorian supports keeping an initial intensity of 130 kt. Dorian is forecast to move over a deep layer of very warm waters, and with the prevailing low shear along the hurricane's path, some additional strengthening is possible during the next day or so. Most likely, however, the hurricane will experience some fluctuations in intensity due to eyewall replacement cycles that are difficult to predict. Beyond 3 days, as the hurricane begins to gain latitude and encounters increasing shear, gradual weakening is anticipated, but Dorian will remain a dangerous hurricane through 5 days. The best estimate of the initial motion is toward the west or 280 degrees at 8 kt. The hurricane is being steered by the weak flow to the south of the ridge of high pressure over the western Atlantic. In about a day or two, most of the global models shift the high eastward and deepen a trough over the eastern United States. Consequently, the steering currents should collapse and Dorian is anticipated to drift toward the northwest and north-northwest while is moving over the northwestern Bahamas and near the east coast of Florida. After that time, the hurricane should begin to move a little faster northward as the trough over the eastern U.S deepens and should then steer the hurricane toward the northeast by the end of the forecast period. The guidance has not changed significantly since the earlier run, so it has not been necessary to adjust the NHC forecast in this advisory. The uncertainty in the track is high while the hurricane is moving slowly across the northwestern Bahamas and near the east coast of Florida. Any deviation of Dorian's core to the left would result in an increase in the winds along the east coast of Florida. Given that the area of tropical storm force winds could expand, and taking into account the uncertainty in the track forecast, a tropical storm watch was issued for the east of Florida from Deerfield Beach to Sebastian Inlet. Key Messages: 1. A prolonged period of life-threatening storm surge, devastating hurricane-force winds, and heavy rains capable of life-threatening flash floods are expected on the Abaco Islands and Grand Bahama Sunday through Monday, and a hurricane warning is in effect for these areas. 2. A tropical storm watch is in effect for a portion of the Florida east coast. Since Dorian is forecast to slow down and turn northward as it approaches the coast, life-threatening storm surge and dangerous hurricane-force winds are still possible along portions of the Florida east coast by the early to middle part of next week. Residents should have their hurricane plan in place, know if they are in a hurricane evacuation zone, and listen to advice given by local emergency officials. 3. There is an increasing risk of strong winds and dangerous storm surge along the coasts of Georgia, South Carolina, and North Carolina during the middle of next week. Residents in these areas should continue to monitor the progress of Dorian. 4. Heavy rains, capable of life-threatening flash floods, are possible over coastal sections of the southeastern United States from Sunday through much of next week.

DISCUSSION AND OUTLOOK ---------------------- At 500 PM EDT (2100 UTC), the distinct eye of Hurricane Dorian was located near latitude 26.2 North, longitude 74.4 West. Dorian is moving toward the west near 8 mph (13 km/h), and a slower westward motion should continue for the next day or two, followed by a gradual turn toward the northwest. On this track, the core of Dorian should move be near or over portions of the northwestern Bahamas on Sunday, and move closer to the Florida east coast late Monday through Tuesday. Maximum sustained winds remain near 150 mph (240 km/h) with higher gusts. Dorian is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely, 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 estimated minimum central pressure is 945 mb (27.91 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. Tropical storm conditions are possible within the tropical storm watch area on Monday. 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 the Abaco Islands and Grand Bahama Island. 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...4 to 8 inches, isolated 12 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.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sat Aug 31 2019

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Hurricane
Dorian, located a few hundred miles east-northeast of the
northwestern Bahamas.

A tropical wave located a little more than 100 miles east of the
Cabo Verde Islands is producing widespread cloudiness and showers.
Environmental conditions are forecast to be conducive for
development of this disturbance during the next few days and a
tropical depression could form next week while the system moves
across the eastern tropical Atlantic Ocean. Heavy rainfall is
possible over portions of the southern Cabo Verde Islands during the
next couple of days, and interests on those islands should monitor
the progress of this system.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.

A broad area of low pressure located over the southeastern Gulf of
Mexico is producing limited shower and thunderstorm activity. Some
gradual development of this system is possible during the next
few days while it moves slowly westward across the southern and
southwestern Gulf of Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

Issued at 1100 AM EDT Sat Aug 31 2019 000 WTNT45 KNHC 311456 TCDAT5 Hurricane Dorian Discussion Number 29 NWS National Hurricane Center Miami FL AL052019 1100 AM EDT Sat Aug 31 2019 Dorian's satellite presentation is outstanding with a distinct eye of about 15 n mi in diameter. Both NOAA and Air Force Hurricane Hunter planes have been penetrating the eye this morning and based on a blend of the flight-level and SFMR winds, the initial intensity has been adjusted upward to 130 kt in this advisory. Dorian is forecast to move over a deep layer of very warm waters, which is like high octane-fuel for hurricanes. The combination of the warm ocean and the prevailing low shear along Dorian's path should favor some additional strengthening, but most likely the hurricane will experience some fluctuations in intensity due to eyewall replacement cycles that are difficult to predict. Beyond 3 days, as the hurricane begins to gain in latitude a gradual weakening is anticipated. Plane fixes indicate that Dorian is moving toward the west or 280 degrees at 7 kt, steered by weak flow to the south of the ridge of high pressure over the western Atlantic. Most of the global models shift the high eastward and deepens a trough over the eastern United States beyond 2 days. This steering flow would typically favor a gradual turn of the hurricane to the northwest and north, however there is large uncertainty in the exact location and timing of this northward turn. Although the latest guidance has shifted a little bit eastward again this morning, there are still ECMWF and GFS ensemble members that do not forecast the northward turn so soon. On this basis, NHC prefers to shift the track forecast just a little bit to the right of the previous one, and the new official forecast lies along the western edge of the guidance envelope. This will allow for further adjustments in the track during future forecast cycles. Key Messages: 1. A prolonged period of life-threatening storm surge and devastating hurricane-force winds are expected in portions of the northwestern Bahamas, particularly on the Abaco Islands and Grand Bahama Island. A hurricane warning is in effect for these areas, and residents should listen to advice given by local emergency officials and have their hurricane preparations completed today. 2. Life-threatening storm surge and dangerous hurricane-force winds are still possible along portions of the Florida east coast by the early to middle part of next week, but since Dorian is forecast to slow down and turn northward near or just offshore of the coast, it is too soon to determine when or where the highest surge and winds could occur. Residents should have their hurricane plan in place, know if they are in a hurricane evacuation zone, and listen to advice given by local emergency officials. 3. The risk of strong winds and dangerous storm surge is increasing along the coasts of Georgia, South Carolina, and North Carolina during the middle of next week. Residents in these areas should continue to monitor the progress of Dorian. 4. Heavy rains, capable of life-threatening flash floods, are expected over portions of the Bahamas and coastal sections of the southeastern United States this weekend through much of next week.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Warning is in effect for... * Northwestern Bahamas excluding Andros Island A Hurricane Watch is in effect for... * Andros Island A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area. Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. Interests in southern and central Florida should continue to monitor the progress of Dorian. Watches may be required for portions of the east coast of Florida later today. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM EDT (1500 UTC), the distinct eye of Hurricane Dorian was located near latitude 26.0 North, longitude 73.4 West. Dorian is moving toward the west near 8 mph (13 km/h) and 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 move near the Florida east coast late Monday through Tuesday. Data from both NOAA and Air Force Hurricane Hunter planes indicate that the maximum sustained winds have increased to near 150 mph (240 km/h) with higher gusts. Dorian is a category 4 hurricane on the Saffir-Simpson Hurricane Wind Scale. Some fluctuations in intensity are likely, 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 115 miles (185 km). The minimum central pressure reported from both reconnaissance planes was 945 mb (27.91 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...4 to 8 inches, isolated 12 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.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sat Aug 31 2019

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Hurricane
Dorian, located a few hundred miles east of the northwestern
Bahamas.

A tropical wave located about midway between the coast of Africa
and the Cabo Verde Islands continues to produce a large area of
showers and a few thunderstorms. Environmental conditions appear
conducive for development of this system, and a tropical depression
could form next week while the system moves across the eastern
tropical Atlantic Ocean. Heavy rainfall is possible over portions
of the southern Cabo Verde Islands during the next few days, and
interests on those islands should monitor the progress of this
system.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...60 percent.

A broad area of low pressure located over the southeastern Gulf of
Mexico is producing disorganized showers and thunderstorms. Some
gradual development of this system is possible during the next
several days while it moves slowly westward across the southern and
southwestern Gulf of Mexico.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
