Hurricane Maria Moves Away from Puerto Rico

Hurricane Maria moved away from Puerto Rico on Wednesday night after causing significant wind damage and serious flash floods.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Maria was located at latitude 19.2°N and longitude 67.9°W which put it about 55 miles (85 km) northeast of Punta Cana, Dominican Republic.  Maria was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 110 m.p.h. (175 km/h) and there were wind gusts to 130 m.p.h. (210 km/h).  The minimum surface pressure was 959 mb.

Hurricane Warnings are in effect for the Turks and Caicos, the Southeastern Bahamas, and the portion of the coast from Cabo Engano to Puerto Plata, Dominican Republic.  A Hurricane Watch is in effect for the portion of the coast from Cabo Engano to Isla Saona, Dominican Republic.  Tropical Storm Warnings are in effect for the portions of the coast from Puerto Plata to the northern border with Haiti and from Cabo Engano to Punta Palenque, Dominican Republic.

Hurricane Maria made landfall on the southeast coast of Puerto Rico near Yabucoa on Wednesday morning.  Maria was a Category 4 hurricane on the Saffir-Simpson Scale at the time of landfall.  Hurricane Maria moved northwest across Puerto Rico and the center emerged over the Atlantic Ocean near Arecibo on Thursday afternoon.

Hurricane Maria weakened as the core of the hurricane moved across Puerto Rico.  The mountains on Puerto Rico disrupted the circulation in the lower levels of Maria, but the middle and upper portions of the circulation remained intact.  Hurricane Maria was in the middle of an eyewall replacement cycle when it made landfall in Puerto Rico.  The timing of landfall may have caused Maria to weaken more than it would have if there had not been an eyewall replacement cycle.  The inner eyewall which contained the strongest winds dissipated at Hurricane Maria moved across Puerto Rico.  The strongest winds are occurring in the remaining outer eyewall.  The eyewall replacement cycle contributed to an increase in the size of the circulation of Hurricane Maria.  Wind to hurricane force extend out about 60 miles (95 km) from the center of circulation.  Wind to tropical storm force extend out about 160 miles (260 km) from the center.

Hurricane Maria will move through an environment favorable for intensification on Thursday.  Maria will move over water where the Sea Surface Temperature is near 29°C.  The upper level winds are weak and there is not much vertical wind shear.  It could take another 12 to 24 hours for the lower portions of the circulation to reorganize.   The reorganization could limit the rate of intensification.  In addition the center will pass near the Dominican Republic.  Some of the southern part of the circulation will be over land and that could also limit intensification until Maria moves farther away from Hispaniola.

Hurricane Maria is moving around the southwestern portion of the subtropical high over the Atlantic Ocean.  That high has been steering Maria toward the northwest.  Many of the numerical models are forecasting that the high will weaken and Maria will turn toward the north on Thursday.  If the high remains stronger than the models are forecasting, then Hurricane Maria will move farther toward the west.  Hurricane Maria seems to have moved near the left side of the guidance from the numerical models in recent days.  On its forecast track the center of Hurricane Maria will move north of the Dominican Republic on Thursday.  Hurricane Maria could be near the Turks and Caicos on Friday.

Hurricane Maria is still capable of producing extensive significant damage.  Maria will drop heavy rain on parts of the Dominican Republic and there could be flash floods in some places where there is steeper terrain.

Elsewhere, Tropical Storm Jose move slowly east-northeast southeast of Massachusetts.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Jose was located at latitude 39.5°N and longitude 68.2°W which put it about 150 miles (245 km) southeast of Nantucket.  Jose was moving toward the east-northeast at 6 m.p.h. (9 km/h).  The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were ind gusts to 75 m.p.h. (120 km/h).  The minimum surface pressure was 982 mb.  A Tropical Storm Warning was in effect for the portion of the coast from Woods Hole to Sagamore Beach including Block Island, Martha’s Vineyard, Nantucket and Cape Cod.

Category 5 Hurricane Maria Bearing Down on Puerto Rico

Category 5 Hurricane Maria was bearing down on Puerto Rico on Tuesday night.  The eye was very near St. Croix.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Maria was located at latitude 17.3°N and longitude 64.7°W which put it about 30 miles (45 km) south-southeast of St. Croix and about 120 miles (190 km) southeast of San Juan, Puerto Rico.  Maria was moving toward the west-northwest at 10 m.p.h. (16 km/h).  The maximum sustained wind speed was 175 m.p.h. (280 km/h) and there were wind gusts to 215 m.p.h. (345 m/h).  The minimum surface pressure was 909 mb.

Hurricane Warnings were in effect for Puerto Rico, Culebra, Vieques, the U.S. Virgin Islands, the British Virgin Islands, and for the portion of the coast from Cabo Engano to Puerto Plata, Dominican Republic.  Hurricane Watches were in effect for the Turks and Caicos, the Southeastern Bahamas, Saba, St. Maarten, St. Martin, St. Eustatius, St. Barthelemy, and the portion of the coast from Isla Saona to Cabo Engano, Dominican Republic.  Tropical Storm Warnings were in effect for Saba, St. Eustatius, St. Maarten, the portion of the coast from Puerto Plata,, Dominican Republic to the northern border with Haiti and for the portion of the coast from Cabo Engano to Punta Palenque, Dominican Republic,

Hurricane Maria is a very well organized powerful hurricane.  It has a small inner eye and a second outer eyewall extends most of the way around the inner eyewall.  The strongest winds are occurring in the inner eyewall.  Additional spiral bands are revolving around the core of the circulation.  The concentric eyewalls have caused the circulation of Hurricane Maria to increase in size.  Winds to hurricane force now extend out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extend out about 160 miles (260 km) from the center.

The Hurricane Intensity Index (HII) for Hurricane Maria is 40.4.  The Hurricane Size Index (HSI) is 19.2 and the Hurricane Wind Intensity Size Index (HWISI) is 59.6.  Those indices indicate that Hurricane Maria is capable of causing regional catastrophic damage.

Hurricane Maria will continue to move through an environment favorable for powerful hurricanes until it reaches Puerto Rico.  Maria will move over water where the Sea Surface Temperature is near 29°C.  The upper level winds are weak and there is little vertical wind shear.  If the outer eyewall completely encircles the inner eyewall, then an eyewall replacement cycle could cause some weakening.  Hurricane Maria will weaken more if the center moves directly over Puerto Rico.  The amount of weakening will depend on the stage of the eyewall replacement cycle at the time of landfall.

Hurricane Maria is being steered toward the west-northwest by the subtropical high pressure system over the Atlantic Ocean.  The western end of the high is forecast to weaken during the next several days.  The weakening of the high will allow Hurricane Maria to move more toward the north.  The core of Hurricane Maria will pass near or over St. Croix during the next few hours.  On its anticipated track Hurricane Maria will reach Puerto Rico on Wednesday morning.

Hurricane Maria is a very dangerous hurricane.  It is capable of causing catastrophic damage.  Maria will also drop very heavy rain over Puerto Rico and there is the potential for significant flash flooding.  Maria could also cause a storm surge of up to 12 feet (4 meters) along the coast.

Elsewhere, Hurricane Jose weakened to a tropical storm east of the U.S.  At 11:00 p.m. EDT on Tuesday the center of Tropical Storm Jose was located at latitude 37.9°N and longitude 70.8°W which put it about 230 miles (375 km) south of Nantucket.  Jose was moving toward the northeast at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 70 m.p.h. (110 km/h) and there were wind gusts to 85 m.p.h. (135 km/h).  The minimum surface pressure was 973 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Woods Hole to Sagamore Beach, Massachusetts including Block Island, Martha’s Vineyard, Nantucket and Cape Cod.  A Tropical Storm Watch was in effect for the portion of Long Island from Fire Island Inlet to Port Jefferson.

Maria Becomes a Hurricane, Jose Prompts Watches for Northeast U.S.

A reconnaissance plane found that Tropical Storm Maria had intensified into a hurricane as it moved toward the Leeward Islands on Sunday afternoon.  At the same time Hurricane Jose moved farther north and Tropical Storm Watches were issued for the coast of the northeastern U.S.  At 5:00 p.m. EDT on Sunday the center of Hurricane Maria was located at latitude 13.8°N and longitude 57.5°W which put it about 275 miles (445 km) east-southeast of Dominica.  Maria was moving toward the west-northwest at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 75 m.p.h. (120 km/h) and there were wind gusts to 90 m.p.h. (150 km/h).  The minimum surface pressure was 982 mb.

Hurricane Warnings were in effect for Guadeloupe, Dominica, St. Kitts, Nevis and Montserrat.  Hurricane Watches were in effect for the U.S. Virgin Islands, the British Islands, Saba, St. Eustatius, St. Maarten, St. Martin, St. Barthelemy, and Anguilla.  Tropical Storm Warnings were in effect for Martinique, St. Lucia, Antigua, Barbuda, Saba, and St. Eustatius.  Tropical Storm Watches were in effect for Barbados, St. Vincent and the Grenadines.

A reconnaissance plane found sustained winds to hurricane force when it investigated Hurricane Maria on Sunday afternoon.  The plane reported a circular eye with a diameter of 32 miles (52 km) at the center of circulation.  The eye was surrounded by an almost complete ring of thunderstorms.  The ring was broken south of the center.  The strongest winds wind occurring in that ring of thunderstorms.  Additional bands of showers and thunderstorms were developing in the eastern half of the circulation.  There were fewer showers and thunderstorms in the western half of Maria.  Hurricane Maria was generating upper level divergence which was pumping away mass and allowing the surface pressure to decrease.

Hurricane Maria will move through an environment that will be favorable for intensification.  Maria will move over water where the Sea Surface Temperature is near 29°C.  An upper level low over Caribbean Sea is causing southern winds which are blowing near the eastern side of Hurricane Maria.  Those winds do not appear to be causing significant vertical wind shear.  Hurricane Maria is likely to continue to intensify as it moves toward the Leeward Islands.  Maria could intensify rapidly once a fully closed eye develops.

Hurricane Maria is being steered toward the west-northwest by the subtropical high pressure system over the Atlantic Ocean and that general motion is expected to continue for several more days.  On its anticipated track Hurricane Maria could reach the Leeward Islands by later on Monday.  Maria could be near Puerto Rico by Wednesday.  Hurricane Maria will affect some of the same islands damaged by Hurricane Irma a few days ago.  Strong winds and heavy rain will significantly impact recovery efforts in those areas.

A reconnaissance plane also found that Hurricane Jose was stronger on Sunday afternoon.  At 5:00 p.m. EDT on Sunday the center of Hurricane Jose was located at latitude 31.5°N and longitude 71.8°W which put it about 335 miles (535 km) southeast of Cape Hatteras, North Carolina.  Jose was moving toward the north at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 90 m.p.h. (150 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 967 mb.

Tropical Storm Watches have been issued for the portions of the coast from Fenwick Island, Delaware to Sandy Hook, New Jersey and from East Rockaway Inlet, New York to Plymouth, Massachusetts including Long Island Sound, Block Island, Martha’s Vineyard and Nantucket.

Hurricane Jose strengthened on Sunday as it moved over water where the Sea Surface Temperature was near 29°C.  An eye appeared at times on visible satellite imagery.  The circulation of Hurricane Jose increased in size which often happens when hurricanes move north out of the tropics.  Winds to hurricane force extended out about 60 miles (95 km) from the center of circulation.  Winds to tropical storm force extended out about 290 miles (470 km) from the center.

Hurricane Jose will move through an environment which will be marginal for further intensification.  Jose will move over water which is warm enough to support intensification.  However, an upper level trough over the eastern U.S. is producing southerly winds which are blowing toward the top of the circulation.  Those winds are producing strong vertical wind shear and they could weaken Jose during the next several days.  Jose will be moving over warm water until it gets north of the Gulf Stream.  If the upper level winds slow, then Jose could get stronger.

Hurricane Jose is being steered northward by the subtropical high over the Atlantic Ocean and the trough over the eastern U.S.  On its anticipated track the center of Jose is forecast to move toward the northeastern U.S. and turn toward the east before it reaches the coast.  If Jose follows the forecast track, then the core of the hurricane would remain offshore.  However, the circulation of Jose is large enough that even if the center stays offshore, there could still be tropical storm force winds along the coast.

Powerful Hurricane Irma Approaches Bahamas, Watches Issued for Florida

Powerful Hurricane Irma move north of the Dominican Republic on its approach to the Bahamas on Thursday morning.  Hurricane Watches were issued for south Florida because of the potential impact of Hurricane Irma.  At 11:00 a.m. EDT on Thursday the center of Hurricane Irma was located at latitude 20.4°N and longitude 69.7°W which put it about 120 miles (190 km) southeast of Grand Turk Island and about 785 miles (1265 km) east-southeast of Miami, Florida.  The maximum sustained wind speed was 175 m.p.h. (280 km/h) and there were wind gusts to 200 m.p.h. (320 km/h).  The minimum surface pressure was 921 mb.

Hurricane Warnings were in effect for the portion of the coast from Cabo Engano, Dominican Republic to Le Mole St. Nicholas, Haiti, the Turks and Caicos, the southeastern Bahamas including the Acklins, Crooked Island, Long Cay, the Inaguas, Mayaguana and the Ragged Islands, the central Bahamas including Cat Island, the Exumas, Long Island, Rum Cay and San Salvador, the northwestern Bahamas including the Abacos, Andros Island, Berry Island, Bimini, Eleuthera, Grand Bahama Island and New Providence.

A Hurricane Watch was in effect for the portion of the coast from Jupiter Inlet to Bonita Beach, Florida including the Florida Keys and Lake Okeechobee and from Matanzas province to Guantanamo province in Cuba.

A Tropical Storm Warning is in effect for the portion of the coast from Cabo Engano, Dominican Republic to the southern border with Haiti, from Le Mole St. Nicholas to Port Au Prince, Haiti and for the Cuban provinces of Guantanamo, Holguin and Las Tunas.

Hurricane Irma remains a large and dangerous hurricane.  Irma weakened slightly on Thursday morning, but it still was a Category 5 hurricane on the Saffir-Simpson Scale.  Irma has a large circular eye at the center of circulation.  The eye is surrounded by a ring of strong thunderstorms and the strongest winds are occurring in that ring of storms.  Winds to hurricane force extend out about 60 miles (95 km) from the center.  Winds to tropical storm force extend out about 185 miles (305 km) from the center.

The Hurricane Intensity Index (HII) for Hurricane Irma is 40.4.  The Hurricane Size Index (HSI) is 19.2 and the Hurricane Wind Intensity Size Index (HWISI) is 59.6.  Those indices indicate that Hurricane Irma is capable of causing widespread catastrophic damage.

Hurricane Irma will remain in a favorable environment for the next several days.  Irma will move over water where the Sea Surface Temperature is near 30°C.  The upper level winds will be weak and there will be little vertical wind shear during the next 24 to 36 hours.  When Irma gets farther north it will be near the southern end of a large upper level trough over the eastern U.S.  The trough will produce southeasterly winds which will increase the shear somewhat.  Hurricane Irma will remain a large dangerous hurricane.

Hurricane Irma is moving around the western end of a subtropical high over the Atlantic Ocean.  The high is steering Irma toward the west-northwest and that general motion is expected to continue for another 36 to 48 hours.  The effects of the upper level trough are expected to turn Irma toward the north during the weekend.  On its anticipated track Hurricane Irma will reach the Turks and Caicos on Thursday night.  Irma will move across the southeastern Bahamas on Friday and it could be north of Cuba by Saturday morning.  Hurricane Irma could reach southern Florida by Sunday morning.

Hurricane Irma is capable of causing widespread catastrophic damage.  Irma will generate storm surges as high as 19 feet (6 meters) when it passes over the Bahamas.  Irma will cause widespread wind damage and locally heavy rain could cause flash floods.

The destructive core of Hurricane Irma moved over Barbuda, St. Barthelemy and St. Martin.  There are reports of widespread damage on those islands.  Other nearby islands my have also suffered significant damage.

Hurricane Jose is following in the wake of Hurricane Irma and Watches have been issued for some of the northern Leeward Islands.  At 11:00 a.m. EDT on Thursday the center of Hurricane Jose was located at latitude 14.9°N and longitude 50.6°W which put it about 715 miles (1155 km) east of the Leeward Islands.  Jose was moving toward the west-northwest at 18 m.p.h. (30 km/h).  The maximum sustained wind speed was 90 m.p.h. (150 km/h) and there were wind gusts to 105 m.p.h. (170 km/h).  The minimum surface pressure was 986 mb.

Hurricane Watches have been issued for Antigua and Barbuda.  Tropical Storm Watches have been issued for Anguilla, Montserrat, St. Kitts and Nevis.

Hurricane Jose is moving through a favorable environment of warm Sea Surface Temperatures and little vertical wind shear.  Hurricane Jose is forecast to intensify into a major hurricane.  The same subtropical high steering Hurricane Irma is also steering Hurricane Jose.  On its anticipated track Hurricane Jose could reach the northern Leeward Islands on Saturday.  It could be a major hurricane at that time.  If Hurricane Jose moves over some of the same places hit by Hurricane Irma it will serious impede efforts to recover from Irma.

Hurricane Katia is threatening parts of Mexico.  At 11:00 a.m. EDT on Thursday the center of Hurricane Katia was located at latitude 21.6°N and longitude 94.6°W which put it about 215 miles (345 km) east of Tampico, Mexico.  Katia was stationary.  the maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (155km/h)  The minimum surface pressure was 980 mb.

A Hurricane Warning is in effect for the portion of the coast from Cabo Rojo to Laguna Verde, Mexico.

 

Hurricane Irma Strengthens to Cat. 4, Watch in effect for Puerto Rico

Hurricane Irma strengthened to Category 4 on the Saffir-Simpson Scale on Monday and a Hurricane Watch was issued for Puerto Rico and the U.S. Virgin Islands.  At 5:00 p.m. EDT on Monday the center of Hurricane Irma was located at latitude 16.7°N and longitude 54.4°W which put it about 490 miles (790 km) east of the Leeward Islands.  Irma was moving toward the west at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 130 m.p.h. (215 km/h) and there were wind gusts to 160 m.p.h. (260 km/h).  The minimum surface pressure was 944 mb.

Hurricane Warnings are in effect for Antigua, Barbuda, Anguilla, Montserrat, St. Kitts, Nevis, Saba, St. Eustatius, St. Maarten, St. Martin, and St. Barthelemy.  Hurricane Watches are in effect for Guadeloupe, the British Virgin Islands, the U.S. Virgin Islands, Puerto Rico, Vieques and Culebra.  A Tropical Storm Warning is in effect for Guadeloupe.  A Tropical Storm Watch is in effect for Dominica.

The circulation of Hurricane Irma has been going through a series of eyewall replacement cycles.  A plane flying through Irma reported concentric eyewalls earlier today.  The two eyewalls appear to have merged.  A small circular eye is at the center of circulation.  A ring of strong thunderstorms surrounds the eye and the strongest winds are occurring in that ring of storms.  Additional bands of showers and thunderstorms are revolving around the core of Hurricane Irma.  Storms around the center are generating strong upper level divergence which is pumping away mass in all directions from the hurricane.

Hurricane Irma has been increasing in size.  Winds to hurricane force extend out about 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extend out about 140 miles (225 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Irma is 25.1.  The Hurricane Size Index (HSI) is 13.6.  The Hurricane Wind Intensity Size index (HWISI) is 38.7.

Hurricane Irma will move through an environment very favorable for tropical cyclones.  Irma will move over water where the Sea Surface Temperature is near 30°C.  The upper level winds are weak and there is little vertical wind shear.  Hurricane Irma could strengthen further and it has a chance to reach Category 5 on the Saffir-Simpson Scale.  Hurricane Irma is likely to go through additional eyewall replacement cycles, which will cause fluctuations in its intensity, but Irma should remain a strong hurricane as it nears the northern Leeward Islands.

The subtropical high pressure system over the Atlantic Ocean has been steering Hurricane Irma toward the west and that general motion is expected to continue for another 12 to 24 hours.  After that time Irma is expected to turn more toward the west-northwest.  On its anticipated track Hurricane Irma will approach the northern Leeward Islands late on Tuesday.  Hurricane Irma could approach Puerto Rico on Wednesday.

Hurricane Irma Moves Toward Leeward Islands, Watches Issued

Hurricane Irma moved toward the northern Leeward Islands on Sunday and Hurricane Watches were issued for a number of those islands.  At 11:00 p.m. EDT on Sunday the center of Hurricane Irma was located at latitude 17.2°N and longitude 51.0°W which put it about 710 miles (1145 km) east of the Leeward Islands.  Irma was moving toward the west-southwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 140 m.p.h. (225 km/h).  The minimum surface pressure was 961 mb.

Hurricane Watches were in effect for Antigua, Barbuda, Anguilla, Montserrat, St. Kitts, Nevis, Saba, St. Eustatius, St. Maarten, St, Martin, and St. Barthelemy.

The circulation of Hurricane Irma is very well organized.  There is a nearly circular eye with a diameter of 30 miles (48 km) at the center of circulation.  The eye is surrounded by a ring of strong thunderstorms and the strongest winds are occurring in the northeastern part of the ring.  Bands of showers and thunderstorms are revolving around the core of Hurricane Irma.  Thunderstorms around the core are generating strong upper level divergence which is pumping mass away in all directions from the hurricane.  Winds to hurricane force extend out about 35 miles (55 km) from the center.  Winds to tropical storm force extend out about 140 miles (225 km) from the center.

The Hurricane Intensity Index (HII) for Hurricane Irma is 20.6.  The Hurricane Size Index (HSI) is 11.7 and the Hurricane Wind Intensity Size Index (HWISI) is 32.3.

Hurricane Irma will move through an environment favorable for intensification.  Irma will move over water where the Sea Surface Temperature is near 29°C and there is warmer water farther west.  The upper level winds are weak and there is little vertical wind shear.  Hurricane Irma could intensify into a Category 4 hurricane on the Saffir-Simpson Scale.  There is a possibility that Irma could strengthen to Category 5 when it passes near the northern Leeward Islands and moves toward the Bahamas.  Hurricane Irma has already completed several eyewall replacement cycles and there could be more.  Each eyewall replacement cycle could result in fluctuations in the intensity of Hurricane Irma.

A strong subtropical high pressure system over the Atlantic Ocean is steering Hurricane Irma toward the west-southwest.  The high is forecast to weaken just a bit during the next several days and Hurricane Irma is expected to move more toward the west-northwest.  On its anticipated track Hurricane Irma will approach the northward Leeward Islands on Tuesday night.  It will be a strong, dangerous hurricane at that time.

Tropical Depression Four

A reconnaissance aircraft found westerly winds in the southeastern side of a low pressure system over the Southeastern Bahamas and was able to close off a center of circulation.  As a result the National Hurricane Center classified the low as Tropical Depression Four (TD4).  At 5:00 p.m. EDT on Saturday the center of TD4 was located at latitude 21.8°N and longitude 72.3°W which put it about 75 miles northeast of Great Inagua Island in the Bahamas and about 560 miles east-southeast of Miami, Florida.  TD4 was moving toward the northwest at 12 m.p.h.  The maximum sustained wind speed was 35 m.p.h. and the minimum surface pressure was 1005 mb.

Tropical Storm Warnings have been issued for the Southeastern Bahamas including The Acklins, Crooked Island, Long Cay, The Inaguas, Mayaguana and the Ragged Islands as well as The Turks and Caicos Islands and the Central Bahamas including Cat Island, The Exumas, Long Island, Rum Cay and San Salvador.

A small upper low north of Cuba is causing some wind shear over the western portion of TD4.  On the other hand the Sea Surface Temperatures around The Bahamas are very warm and TD4 is very likely to intensify into Tropical Storm Cristobal and eventually into a hurricane.  Since the center has just formed the motion and future track are still highly uncertain, although a general motion toward the southeastern U.S. seems likely.
