Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sun Sep 1 2019

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

The National Hurricane Center is issuing advisories on Hurricane
Dorian, located near the Abacos.

A broad area of low pressure associated with a tropical wave is
located just south of the Cabo Verde Islands. This system has become
better organized since yesterday, and environmental conditions
appear conducive for additional development during the next several
days. A tropical depression is likely to form by the middle of the
week while the system moves generally northwestward 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...medium...50 percent.
* Formation chance through 5 days...high...70 percent.

Another broad area of low pressure is located over the south-central
Gulf of Mexico. This disturbance is producing limited and
disorganized shower 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 toward
the coast of Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

An area of disturbed weather is located several hundred miles
south-southeast of Bermuda. Some gradual development of this system
is possible during the next few days while it moves slowly northward
or north-northwestward.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

Hurricane Dorian Forecast Discussion Number 32

5 years 10 months ago
Issued at 500 AM EDT Sun Sep 01 2019 000 WTNT45 KNHC 010859 TCDAT5 Hurricane Dorian Discussion Number 32 NWS National Hurricane Center Miami FL AL052019 500 AM EDT Sun Sep 01 2019 Dorian continues to exhibit a well-defined eye surrounded by very cold cloud tops on satellite images. Observations from an Air Force Hurricane Hunter aircraft from several hours ago indicated that the intensity was still near 130 kt, and since the cloud pattern remains very impressive, it is assumed that Dorian has at least maintained that strength through the present time. The hurricane will remain in a fairly low-shear environment for the next few days, however since it is forecast to move quite slowly over the shallow waters of the northwesternnmost Bahamas through Monday, this would likely result in less available oceanic heat content. Therefore, a very slow weakening is anticipated to commence after 12 hours or so. The official intensity forecast is near the high end of the numerical guidance suite. The hurricane continues moving westward, or about 280/7 kt. A high pressure ridge to the north of Dorian should maintain this westward movement through today. By tonight, the global models show the ridge weakening, and this evolution should result in a slowing of the forward speed, with the hurricane becoming nearly stationary around 48 hours. In comparison to its earlier runs, the new ECMWF track forecast takes the system farther to the west during the next couple of days, and is the southwesternmost model through 48 hours. As a result, the official track forecast has been shifted a little west during that time frame. In 2 to 4 days, Dorian should turn northward in response to a trough over the eastern United States. By the end of the period, the flow on the south side of the trough should cause the cyclone to move northeastward near the Carolinas. The westward shift of the NHC track within the first 48 hours necessitates the change from a Tropical Storm Watch to a Tropical Storm Warning for a portion of the Florida east coast. Although the official track forecast does not show landfall, users should not focus on the exact track since a Florida landfall is still a distinct possibility. Key Messages: 1. A prolonged period of life-threatening storm surge, devastating hurricane-force winds, and heavy rains capable of producing life-threatening flash floods are expected on the Abaco Islands and Grand Bahama through Monday, and a hurricane warning is in effect for these areas. 2. A tropical storm warning is now 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 middle part of this 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 later this week. Residents in these areas should continue to monitor the progress of Dorian. 4. Heavy rains, capable of producing life-threatening flash floods, are possible over coastal sections of the southeast and lower mid-Atlantic regions of the United States through late this week.

DISCUSSION AND OUTLOOK ---------------------- At 500 AM EDT (0900 UTC), the center of Hurricane Dorian was located near latitude 26.4 North, longitude 76.0 West. Dorian is moving toward the west near 8 mph (13 km/h), and a slower westward motion should occur for the next day or two, followed by a gradual turn toward the northwest. On this track, the core of Dorian should be near or over portions of the northwestern Bahamas later today and tonight, and should move closer to the Florida east coast late Monday through Tuesday night. Maximum sustained winds are 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 934 mb (27.58 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the hurricane warning area across the northwestern Bahamas later today, with tropical storm winds beginning within the next few hours. Tropical storm conditions are expected within the tropical storm warning area on Monday. Tropical storm conditions are possible within the tropical storm watch area by Monday night. STORM SURGE: A life-threatening storm surge will raise water levels by as much as 15 to 20 feet above normal tide levels in areas of onshore winds on 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 totals through late this week: Northwestern Bahamas...12 to 24 inches, isolated 30 inches. Coastal Carolinas...5 to 10 inches, isolated 15 inches. Central Bahamas and the Atlantic Coast from the Florida peninsula through Georgia...2 to 4 inches, isolated 6 inches. This rainfall may cause life-threatening flash floods. SURF: Large swells will 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 AM EDT Sun Sep 1 2019

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

The National Hurricane Center is issuing advisories on Hurricane
Dorian, located about 100 miles east of the northwestern Bahamas.

A tropical wave accompanied by a broad low pressure area is located
about 150 miles south the Cabo Verde Islands. Although this
disturbance continues to produce disorganized thunderstorms,
environmental conditions are forecast to be conducive for
development of this disturbance, and a tropical depression could
form during the early or middle part of next week while the system
moves northwestward 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...30 percent.
* Formation chance through 5 days...medium...60 percent.

A broad area of low pressure located over the south-central Gulf
of Mexico is producing limited shower 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 toward the coast of Mexico.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

On this track, the core of Dorian should be near or over portions of the northwestern Bahamas later today, and move closer to the Florida east coast late Monday through Tuesday. Data from an Air Force Reserve Unit Hurricane Hunter aircraft indicate that the 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 minimum central pressure estimated from Hurricane Hunter observations is 934 mb (27.58 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Hurricane conditions are expected in the hurricane warning area across the northwestern Bahamas later today, with tropical storm winds beginning within the next several hours. 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 15 to 20 feet above normal tide levels in areas of onshore winds on 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 from central Florida northward through the Carolinas...4 to 8 inches, isolated 12 inches. Central Bahamas and South Florida...2 to 4 inches, isolated 6 inches. This rainfall may cause life-threatening flash floods. SURF: Large swells will 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.

Hurricane Dorian Forecast Discussion Number 31

5 years 10 months ago
Issued at 1100 PM EDT Sat Aug 31 2019 000 WTNT45 KNHC 010256 TCDAT5 Hurricane Dorian Discussion Number 31 NWS National Hurricane Center Miami FL AL052019 1100 PM EDT Sat Aug 31 2019 Data from both Air Force and NOAA Hurricane Hunter aircraft indicate that Dorian remains a very powerful hurricane, and the satellite presentation is still quite impressive with a very stable, well-defined eye. There has been no evidence of concentric eyewalls in aircraft or microwave data, which is somewhat surprising given that the intensity has been at category 4 strength for 24 hours. Both aircraft measured peak flight-level winds that support an initial intensity of 130 kt. There have been some higher surface wind estimates from the SFMR, but these data are questionable based on our experience of very high SFMR-measured wind speeds in recent strong hurricanes that didn't match standard flight-level wind reductions. Dorian is forecast to continue moving over very warm waters and into a low-shear environment during the next 12-24 hours, so some additional strengthening is possible. Difficult-to-predict eyewall cycles, however, are likely to begin at some point within the next day or so and could cause fluctuations in intensity. After 72 hours, increasing southerly shear is likely to produce gradual weakening, but Dorian is foreast to remain a dangerous hurricane through the forecast period. The hurricane is moving westward or 280/7 kt. A high pressure ridge to the north of Dorian is predicted to remain intact into early Sunday, and the hurricane should continue westward. By late Sunday, the dynamical models erode the western portion of the ridge, which should cause the hurricane to slow down and become nearly stationary over the northwestern Bahamas in 36 to 48 hours. After that time, the weakness in the ridge becomes more pronounced, and Dorian is expected to turn northwestward, and eventually northeastward near the southeastern United States coast. Although there is general agreement on this overall scenario, there is still considerable spread on how close the storm will track to the east coast of Florida and the southeastern coast of the United States. The latest HWRF run has shifted westward and takes Dorian across the coast of central Florida. The 18Z GFS also shifted a little left closer to the Florida coast. The latest multi-model consensus aids shifted west closer to the previous NHC track, so very little change to that forecast was made. Although the exact NHC track forecast lies east of the Florida peninsula, a track closer to the coast or even a landfall remain a possibility. Since the updated track was slightly slower than the previous advisory, no additional watches are needed for Florida at this time. 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 Monday through Thursday.

Preparations to protect life and property should be rushed to completion. A Hurricane Watch means that hurricane conditions are possible within the watch area. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Interests elsewhere in southern and central Florida should continue to monitor the progress of Dorian. Additional watches may be required for portions of the east coast of Florida on Sunday. For storm information specific to your area in the United States, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. For storm information specific to your area outside of the United States, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM EDT (0300 UTC), the center of Hurricane Dorian was located near latitude 26.3 North, longitude 75.1 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 be near or over portions of the northwestern Bahamas on Sunday, and move closer to the Florida east coast late Monday through Tuesday. Data from NOAA and Air Force reconnaissance aircraft indicate that the 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 latest minimum central pressure estimated from reconnaissance aircraft data is 940 mb (27.76 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 overnight. 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 15 to 20 feet above normal tide levels in areas of onshore winds on 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 from central Florida northward through the Carolinas...4 to 8 inches, isolated 12 inches. Central Bahamas and South Florida...2 to 4 inches, isolated 6 inches. This rainfall may cause life-threatening flash floods. SURF: Large swells will 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. NEXT ADVISORY ------------- Next intermediate advisory at 200 AM EDT. Next complete advisory at 500 AM EDT. $$ Forecaster Brown

DISCUSSION AND OUTLOOK ---------------------- At 800 PM EDT (0000 UTC), the distinct eye of Hurricane Dorian was located near latitude 26.2 North, longitude 74.7 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 be near or over portions of the northwestern Bahamas on Sunday, and move closer to the Florida east coast late Monday through Tuesday. Data from NOAA and Air Force Hurricane Hunter aircraft indicate that the maximum sustained winds remain near 150 mph (240 km/h) with higher gusts. Dorian remains 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 latest minimum central pressure reported by reconnaissance aircraft is 941 mb (27.79 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.
