Tropical Storm Elsa Brings Wind and Rain to Northeast U.S.

Tropical Storm Elsa brought wind and rain to the northeast U.S. on Friday morning. At 8:00 p.m. EDT on Friday the center of Tropical Storm Elsa was located at latitude 40.2°N and longitude 73.1°W which put it about 90 miles (145 km) southwest of Montauk Point, New York. Elsa was moving toward the northeast at 31 m.p.h. (50 km/h). The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h). The minimum surface pressure was 1000 mb.

A Tropical Storm Warning was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Warning was also in effect for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts including Block Island, Nantucket, Martha’s Vineyard, and Cape Cod.

Tropical Storm Elsa was buffeting the northeastern U.S. with gusty winds and locally heavy rain on Friday morning. The center of Elsa was passing south of Long Island, but rain was falling over an area that extended from New York City to southern Maine. Winds to tropical storm force extended out 150 miles (240 km) to the southeast of the center of Elsa. Winds to tropical storm force also extended out 80 miles (130 km) to the northeast of the center of circulation. Winds in the western half of Tropical Storm Elsa were not as strong. Elsa could cause sporadic power outages and flash floods in the northeastern U.S. on Friday.

Tropical Storm Elsa will make a transition to an extratropical cyclone during the next 24 hours, while it moves quickly toward the northeast. Elsa will move over water where the Sea Surface Temperatures are near 22°C. An upper level trough over the Great Lakes will produce strong southwesterly winds that will blow toward the top of Elsa’s circulation. Those winds will cause strong vertical wind shear. The combination of cooler Sea Surface Temperatures and strong wind shear will cause the structure of Tropical Storm Elsa to change to the structure of an extratropical cyclone. The center of Elsa will pass near Cape Cod on Friday afternoon. Elsa will pass over the Canadian Maritime Provinces on Friday night. It could be near Labrador and eastern Newfoundland on Saturday.

Tropical Storm Elsa Moves over North Carolina

Tropical Storm Elsa moved over North Carolina on Thursday. At 2:00 p.m. EDT on Thursday the center of Tropical Storm Elsa was located at latitude 35.6°N and longitude 79.0°W which put it about 25 miles (40 km) west of Raleigh, North Carolina. Elsa was moving toward the northeast at 20 m.p.h. (32 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 60 m.p.h. (95 km/h). The minimum surface pressure was 1007 mb.

A Tropical Storm Warning was in effect for the portion of the coast from South Santee River, South Carolina to Sandy Hook, New Jersey. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound. A Tropical Storm Warning was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Warning was also in effect for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts including Block Island, Nantucket, Martha’s Vineyard, and Cape Cod.

Tropical Storm Elsa moved a little more quickly toward the northeast on Thursday. The surface center of Elsa moved over North Carolina. The structure of Elsa exhibited the typical characteristics of a tropical storm moving northeast near the coast of the U.S. Heavy rain was falling in the northeastern part of Tropical Storm Elsa. The heaviest rain was falling on eastern North Carolina and eastern Virginia. Drier air was wrapping around the western and southern sides of Elsa. The strongest winds were blowing in the southeastern part of Tropical Storm Elsa that was over the Atlantic Ocean.

An upper level trough over the Great Lakes will steer Tropical Storm Elsa quickly toward the northeast during the next 36 hours. On its anticipated track Elsa will move over Virginia on Thursday evening. Tropical Storm Elsa could be near Long Island on Friday morning. Elsa could pass near Cape Cod later on Friday. Tropical Storm Elsa will make a transition to an extratropical cyclone when it moves farther north. Elsa will bring gusty winds and heavy rain to the East Coast of the U.S. from North Carolina to Massachusetts. Tropical Storm Elsa could cause sporadic power outages along the East Coast. Locally heavy rain could cause flash floods in some locations.

Tropical Storm Elsa Prompts Warnings for East Coast

Tropical Storm Elsa prompted the issuance of warnings and watches for the East Coast of the U.S. on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Elsa was located at latitude 32.1°N and longitude 82.3°W which put it about 55 miles (90 km) west of Savannah, Georgia. Elsa was moving toward the north-northeast at 16 m.p.h. (26 km/h). The maximum sustained wind speed was 45 m.p.h. (75 km/h) and there were wind gusts to 55 m.p.h. (90 km/h). The minimum surface pressure was 1006 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Altamaha Sound, Georgia to Great Egg Inlet, New Jersey. The Tropical Storm Warning included Pamlico Sound and Albemarle Sound. A Tropical Storm Watch was in effect for the portion of the coast from Great Egg Inlet to Sandy Hook, New Jersey. A Tropical Storm Watch was in effect for the eastern portion of Long Island from East Rockaway Inlet to Port Jefferson Harbor. A Tropical Storm Watch was also in effect for the portion of the coast from New Haven, Connecticut to Sagamore Beach, Massachusetts including Block Island, Nantucket, Martha’s Vineyard, and Cape Cod.

The center of Tropical Storm Elsa was moving across eastern Georgia on Wednesday night. Heavy rain was spreading across South Carolina. Rainbands on the eastern side of Elsa’s circulation were producing winds to tropical storm force over the Atlantic Ocean. NOAA buoy 41008 at Grays Reef reported a sustained wind speed of 38 m.p.h. (61 km/h) and a wind gust of 47 m.p.h. (76 km/h). The circulation around Tropical Storm Elsa was still well defined. A distinct low pressure system was evident on the surface map, radar and satellite displays. Storms on the eastern side of Elsa generated upper level divergence that pumped mass away to the northeast of the tropical storm.

An upper level trough over the Great Lakes will steer Tropical Storm Elsa toward the northeast during the next 48 hours. On its anticipated track Tropical Storm Elsa will move across South Carolina on Thursday morning and North Carolina on Thursday afternoon. Elsa could be over eastern Virginia on Thursday evening and near Long Island by Friday morning. Even though the center of Tropical Storm Elsa will be over land for another 18 to 24 hours, bands on the eastern side of the circulation could produce tropical storm force winds over the Atlantic Ocean and along the East Coast of the U.S. Elsa will also drop locally heavy rain over South Carolina, eastern North Carolina and eastern Virginia. Gusty winds and heavy rain could cause sporadic power outages. Heavy rain could also cause flash floods in some locations.

Tropical Storm Elsa Makes Landfall in Florida

Tropical Storm Elsa made landfall on the coast of north Florida on Wednesday morning. At 11:00 a.m. EDT on Wednesday the center of Tropical Storm Elsa was located at latitude 29.9°N and longitude 83.6°W which put it about 20 miles (30 km) southwest of Perry, Florida. Elsa was moving toward the north at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Aripeka to Ochlockonee River, Florida. A Tropical Storm Warning was also in effect for the portion of the coast from the Mouth of the St. Marys River, Florida to Little River Inlet, South Carolina. A Tropical Storm Watch was in effect for the portion of the coast from Little River Inlet, South Carolina to Sandy Hook New Jersey including Albemarle and Pamlico Sounds.

The center of Tropical Storm Elsa made landfall in Taylor County, Florida about 20 miles southwest of Perry around 11:00 a.m. EDT on Wednesday. Elsa weakened from a hurricane to a strong tropical storm before it made landfall. Bands in the eastern half of the circulation around Tropical Storm Elsa dropped heavy rain over Florida. Rain was beginning to spread over southern Georgia. Gusty winds caused power outages in parts of Florida. Elsa caused a minor storm surge along the west coast of Florida.

Tropical Storm Elsa will weaken steadily during the next 48 hours while the center moves farther inland. Elsa will be steered toward the northeast during the next few days by an upper level trough over the Great Lakes. On its anticipated track Tropical Storm Elsa will move over southern Georgia on Wednesday night. Elsa could be over South Carolina on Thursday morning and it could be over eastern Virginia by Thursday night. Elsa could strengthen back to a tropical storm if the center moves over the Atlantic Ocean later this week.

Tropical Storm Elsa will continue to drop locally heavy rain over northern Florida during the next few hours. Heavy rain will spread over southern Georgia, South Carolina, eastern North Carolina and eastern Virginia. Heavy rain could cause flash floods in some locations. Gusty winds could cause sporadic power outages. There could be enough low level wind shear in stronger rainbands to produce tornadoes. When Tropical Storm Elsa gets closer to the East Coast of the U.S., southeasterly winds will blow water toward the coast. Those winds will cause water levels to rise along the coast

Hurricane Watch Issued for Florida for Tropical Storm Elsa

A Hurricane Watch was issued for a portion of the west coast of Florida because of Tropical Storm Elsa. At 5:00 a.m. EDT on Tuesday the center of Tropical Storm Elsa was located at latitude 24.1°N and longitude 82.4°W which put it about 50 miles (80 km) southwest of Key West, Florida. Elsa was moving toward the north-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 1007 mb.

A Hurricane Watch was issued for the portion of the coast from Egmont Key to Steinhatchee River, Florida. A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to the Dry Tortugas. A Tropical Storm Warning was also in effect for the portion of the coast from Flamingo to Ochlockonee River, Florida. That warning included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings remained in effect for the Cuban provinces of Matanzas, Mayabeque, Havana and Artemisa. A Tropical Storm Watch was in effect for the portion of the coast from Ochlockonee River to Indian Pass, Florida. A Tropical Storm Watch was issued for the portion of the coast from the Mouth of the St. Marys River, Georgia to the South Santee River, South Carolina.

The center of Tropical Storm Elsa was southwest of Key West, Florida on Tuesday morning. The National Weather Service office in Key West reported a wind gust of 47 m.p.h. (76 km/h). The distribution of thunderstorms around Elsa continued to be asymmetrical. The strongest thunderstorms were occurring in bands on the eastern side of Tropical Storm Elsa. Bands on the western side of the storm consisted primarily of showers and lower clouds. Storms near the center or Elsa generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 70 miles from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 18 hours. Elsa will move over water where the Sea Surface Temperatures are near 29°C. It will move under the western end of an upper level ridge. The ridge will produce southwesterly winds that will blow toward the top of Tropical Storm Elsa. Those winds will cause some vertical wind shear that will inhibit intensification. However, the southwesterly winds may also increase upper level divergence to the northeast of Elsa. Additional upper level divergence could cause the surface pressure to decrease on Tuesday. Tropical Storm Elsa could intensify on Tuesday and there is a chance that Elsa could strengthen to a hurricane.

Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Elsa toward the north on Tuesday. Tropical Storm Elsa will turn toward the northeast on Wednesday when it reaches the westerly winds in the middle latitudes. On its anticipated track the center of Elsa will pass west of the Key West on Tuesday morning. The center of Tropical Storm Elsa could pass west of Tampa on Tuesday night. The stronger winds and heavy rain will occur on the eastern side of Elsa. Heavy rain could cause flash floods in some locations. Winds pushing water toward the coast could cause a storm surge of up to six feet (two meters) in Tampa Bay. Tropical Storm Elsa could cause a storm surge of 2 to 5 feet (0.6 to 1.6 m) in the Florida Keys and along the west coast of Florida. A higher storm surge could occur near where the center of Elsa makes landfall. Gusty winds could cause power outages in the Florida Keys and on the Florida peninsula. Elsa will continue to drop heavy rain over parts of Cuba as rainbands on the southern side of the circulation move across the regions

Tropical Storm Elsa Crosses Cuba

Tropical Storm Elsa moved across Cuba during Monday afternoon and evening. At 11:00 p.m. EDT on Monday the center of Tropical Storm Elsa was located at latitude 23.5°N and longitude 82.3°W which put it about 80 miles (130 km) south-southwest of Key West, Florida. Elsa was moving toward the north-northwest at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 1007 mb.

A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to the Dry Tortugas. A Tropical Storm Warning was also in effect for the portion of the coast from Flamingo to Ochlockonee River, Florida. That warning included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings remained in effect for the Cuban provinces of Matanzas, Mayabeque, Havana and Artemisa. A Tropical Storm Watch was in effect for the portion of the coast from Ochlockonee River to Indian Pass, Florida.

The center of Tropical Storm Elsa moved across western Cuba during Monday afternoon and evening. The center passed just to the east of Havana before it moved over water north of Cuba. Tropical Storm Elsa continued to exhibit an organized circulation on satellite and radar imagery even after it spent half a day over land. A reconnaissance plane found sustained winds of 60 m.p.h. (95 km/h) over water north of Cuba. The inner end of a rainband wrapped around the eastern and northern sides of the center of Elsa. Strong thunderstorms were occurring in bands near south Florida and south of Cuba. Storms near the center of Tropical Storm Elsa generated upper level divergence that pumped mass away to the northeast of the tropical storm. Winds to tropical storm force extended out 70 miles (110 km) from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 24 hours. Elsa will move over water where the Sea Surface Temperatures are near 30°C. It will move under the western end of an upper level ridge. The ridge will produce southwesterly winds that will blow toward the top of Tropical Storm Elsa. Those winds will cause some vertical wind shear that will inhibit intensification. However, the southwesterly winds may also increase upper level divergence to the northeast of Elsa. Tropical Storm Elsa could intensify on Tuesday and there is a chance that Elsa could strengthen to a hurricane.

Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Elsa toward the north-northwest during the next few hours. Elsa will move more toward the north on Tuesday. On its anticipated track the center of Elsa will pass west of the Florida Keys on Tuesday morning. The center of Tropical Storm Elsa could pass west of Tampa on Tuesday night. The stronger winds and heavy rain will occur on the eastern side of Elsa. Heavy rain could cause flash floods in some locations. Winds pushing water toward the coast could cause a storm surge of up to six feet (two meters) in Tampa Bay. Tropical Storm Elsa could cause a storm surge of 2 to 5 feet (0.6 to 1.6 m) in the Florida Keys and along the west coast of Florida. A higher storm surge could occur near where the center of Elsa makes landfall. Gusty winds could cause power outages in the Florida Keys and on the Florida peninsula. Elsa will continue to drop heavy rain over parts of Cuba as rainbands on the southern side of the circulation move across the regions

Tropical Storm Elsa Churns South of Cuba

Tropical Storm Elsa was churning south of Cuba on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Storm Elsa was located at latitude 21.5°N and longitude 81.2°W which put it about 20 miles (35 km) east-southeast of Cayo Largo, Cuba. Elsa was moving toward the northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 1006 mb.

Tropical Storm Warnings were in effect for the Florida Keys from Craig Key to the Dry Tortugas and for the portion of the coast from Flamingo to Suwannee River, Florida. The Tropical Storm Warnings included Naples, Ft. Myers, Tampa, St. Petersburg and Tampa Bay. Tropical Storm Warnings were also in effect for the Cuban provinces of Cienfuegos, Matanzas, Ciego de Avila, Sancti Spiritus, Villa Clara, Mayabeque, Havana, Artmemisa. Tropical Storm Watches were in effect for the Florida Keys from Craig Key to Ocean Reef including Florida Bay and for the portion of the coast from Suwannee River, Florida to Indian Pass, Florida.

Tropical Storm Elsa exhibited a little more organization on Monday morning. More thunderstorms formed north and east of the center of Elsa. However, the distribution of thunderstorms remained asymmetrical. The strongest thunderstorms were occurring in bands on the east side of Tropical Storm Elsa. Bands in the western half of the circulation consisted primarily of showers and lower clouds. Storms near the center generated upper level divergence that pumped mass away to the northeast of the tropical storm. Winds to tropical storm force extended out 70 miles from the center of Elsa.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next few hours. Elsa will move over water where the Sea Surface Temperatures are near 30°C. It will move under the western end of an upper level ridge. The ridge will produce southwesterly winds that will blow toward the top of Tropical Storm Elsa. Those winds will cause some vertical wind shear that will inhibit intensification. Tropical Storm Elsa could strengthen a little before it reaches Cuba. Elsa will weaken when the center crosses Cuba. Tropical Storm Elsa could regain some strengthen when it moves over warm water southwest of the Florida Keys, but the upper level ridge will continue to cause vertical wind shear.

Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will steer Elsa toward the northwest during the next few hours. On its anticipated track the center of Tropical Storm Elsa will make landfall on the south coast of Cuba southeast of Havana in a few hours. The center of Elsa will pass west of the Florida Keys on Tuesday morning. The center of Tropical Storm Elsa could pass west of Tampa on Tuesday night. The stronger winds and heavy rain will occur on the eastern side of Elsa. Heavy rain could cause flash floods in some locations. Winds pushing water toward the coast could cause a storm surge of up to six feet ( two meters) along the southern coast of Cuba. Tropical Storm Elsa could cause a storm surge of 2 to 4 feet (0.6 to 1.2 m) in the Florida Keys and along the west coast of Florida. A high storm surge could occur near where the center of Elsa makes landfall.

Tropical Storm Elsa Drops Heavy Rain on Cuba and Jamaica

Tropical Storm Elsa dropped heavy rain over Cuba and Jamaica on Sunday. At 5:00 p.m. EDT on Sunday the center of Tropical Storm Elsa was located at latitude 19.8°N and longitude 77.9°W which put it about 15 miles (25 km) west of Cabo Cruz, Cuba. Elsa was moving toward the west-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 60 m.p.h. (95 km/h) and there were wind gusts to 75 m.p.h. (120 km/h). The minimum surface pressure was 1009 mb.

A Tropical Storm Warning was in effect for the Florida Keys from Craig Key to the Dry Tortugas. Tropical Storm Watches were in effect for the Florida Keys from Craig Key to Ocean Reef including Florida Bay, and for the portion of the coast from from Flamingo to Anclote River, Florida including Tampa Bay. Hurricane Watches were in effect for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas and Santiago de Cuba. Tropical Storm Warnings were also in effect for Jamaica and for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas and Santiago de Cuba, Ciego de Avila, Sancti Spiritus, Cienfuegos, Villa Clara, Matanzas, Maybeque, and Havana. Tropical Storm Watches were in effect for Cayman Brac, Little Cayman and the Cuban province of Artemisa.

Tropical Storm Elsa exhibited organization on visible satellite images and images from weather radars in southeastern Cuba. However, reconnaissance planes flying through Elsa on Sunday morning reported that the tropical storm was not as organized as it appeared to be on satellite and radar images. The planes found that the maximum sustained wind speed was 60 m.p.h. (95 km/h) and that the minimum surface pressure had increased to 1009 mb, which was an usually high pressure for a tropical storm.

The strongest thunderstorms were occurring in bands south and east of the center of Tropical Storm Elsa. Bands in the northwestern part of Elsa consisted primarily of showers and lower clouds. Air sinking down sides of mountains in southeastern Cuba may have been inhibiting the development of thunderstorms in the northwestern quadrant of the circulation. Storms near the center of Elsa generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 18 hours. Elsa will move over water where the Sea Surface Temperatures are near 30°C. It will move under an upper level ridge where the winds are weak and there will be little vertical wind shear. Air on the northern side of Tropical Storm Elsa will pass over Cuba where friction will slow it. However, once Elsa moves west of Jamaica, air converging from the southwest will be able to blow directly toward the center of the tropical storm. A stronger flow of warm humid air from the southwest could provide more energy to the tropical storm. Tropical Storm Elsa could intensify on Monday and there is a chance it could strengthen back to a hurricane before the center moves over Cuba. Elsa will weaken when the center crosses Cuba.

Tropical Storm Elsa will move around the western end of the subtropical high pressure system over the Atlantic Ocean during the next several days. The high will continue to steer Tropical Storm Elsa toward the northwest on Sunday night. Elsa will move more toward the north-northwest on Monday. On its anticipated track the center of Tropical Storm Elsa could make landfall on the south coast of Cuba near Cienfuegos on Monday afternoon. Elsa could reach the Florida Keys on Monday night. Elsa will continue to cause gusty winds and locally heavy rain over parts of Jamaica and Cuba. Heavy rain could cause flash floods in some locations.

Tropical Storm Elsa Prompts Watch for Florida Keys

The forecast of the future track prompted the issuance of a Tropical Storm Watch for the Florida Keys from Craig Key to the Dry Tortugas on Saturday. At 11:00 p.m. EDT on Saturday the center of Tropical Storm Elsa was located at latitude 17.9°N and longitude 75.3°W which put it about 175 miles (280 km) east-northeast of Montego Bay, Jamaica. Elsa was moving toward the west-northwest at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h). The minimum surface pressure was 1004 mb.

Hurricane Watches were in effect for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas and Santiago de Cuba. Tropical Storm Warnings were in effect for Jamaica and for the portion of the coast from Port Au Prince, Haiti to the southern border with the Dominican Republic. Tropical Storm Warnings were also in effect for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas and Santiago de Cuba, Ciego de Avila, Sancti Spiritus, Cienfuegos, and Villa Clara. A Tropical Storm Watch was in effect for the Florida Keys from Craig Key to the Dry Tortugas. Tropical Storm Watches were also in effect for Cayman Brac, Little Cayman and the Cuban provinces of Matanzas, Mayabeque and Havana.

Tropical Storm Elsa looked impressive on infrared satellite images on Saturday night, but data from reconnaissance planes indicated that its circulation was not as well organized as it appeared to be. Very strong thunderstorms developed in bands east of the center of Elsa. Thunderstorms also increased in a band on the western periphery of the tropical storm. However the lower level center of circulation was still to the west of the center in the middle levels of the Tropical Storm Elsa. The lack of vertical alignment of the two centers was preventing Elsa from intensifying on Saturday evening. The strong thunderstorms east of the center were generating strong upper level divergence that was pumping mass away from the tropical storm. Winds to tropical storm force extended out 130 miles (210 km) from the center of Tropical Storm Elsa.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 12 hours. Elsa will move over water where the Sea Surface Temperatures are near 30°C. Tropical Storm Elsa will move more slowly during the next 24 hours. If Elsa moves more slowly, there is a chance that the lower level and middle level centers could become vertically aligned. It will move into a region where the upper level winds are weak and there will be less vertical wind shear. Tropical Storm Elsa could intensify back to a hurricane before it reaches Cuba on Sunday.

Tropical Storm Elsa will move south of the subtropical high pressure system over the Atlantic Ocean during the next 12 hours. The high will continue to steer Tropical Storm Elsa toward the west-northwest, but Elsa is likely to move more slowly. An upper level trough over the eastern U.S. is forecast to weaken the western end of the high pressure system on Sunday. When the high weakens, then Tropical Storm Elsa will move more toward the northwest. On its anticipated track the center of Tropical Storm Elsa will pass just to the north of Jamaica. Elsa could be near eastern Cuba by Sunday morning. Tropical Storm Elsa could approach the Florida Keys on Monday. Elsa will cause gusty winds and locally heavy rain over parts of Haiti, Jamaica and Cuba.

Elsa Weakens South of Hispaniola

Former Hurricane Elsa weakened back to tropical storm intensity while it passed south of Hispaniola on Saturday. At 2:00 p.m. EDT on Saturday the center of Tropical Storm Elsa was located at latitude 17.3°N and longitude 73.0°W which put it about 255 miles (410 km) east of Kingston, Jamaica. Elsa was moving toward the west-northwest at 29 m.p.h. (46 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 1002 mb.

A Hurricane Warning was in effect for the portion of the coast from Port Au Prince, Haiti to the southern border with the Dominican Republic. Hurricane Watches were in effect for the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas and Santiago de Cuba. Tropical Storm Warnings were in effect for the portion of the coast from Port Au Prince to the northern border with the Dominican Republic and from Punta Palenque, Dominican Republic to the southern border with Haiti. Tropical Storm Warnings were also in effect for Jamaica and the Cuban provinces of Camaguey, Granma, Guantanamo, Holguin, Las Tunas, and Santiago de Cuba. A Tropical Storm Watch was in effect for the portion of the coast from Punta Palenque to Cabo Engano, Dominican Republic. Tropical Storm Watches were in effect for Cayman Brac, Little Cayman and the Cuban provinces of Ciego de Avila, Sancti Spiritus, Cienfuegos, Villa Clara and Matanzas.

Strong winds in the lower levels pushed the surface center of former Hurricane Elsa to the west of the center in the middle levels early on Saturday. The displacement between the two centers disrupted the vertical circulation of Elsa and it weakened back to tropical storm intensity. More thunderstorms started to develop east of the center of Tropical Storm Elsa on Saturday morning. Mountains in southwestern Haiti appeared to deflect the low level flow around the northern side of Elsa. More thunderstorms began forming to the north of the center of Tropical Storm Elsa on Saturday afternoon. A NOAA plane appeared to find that the surface pressure was decreasing again at the center of Elsa on Saturday afternoon. Winds to tropical storm force extended out 130 miles (210 km) from the center of circulation.

Tropical Storm Elsa will move through an environment somewhat favorable for intensification during the next 18 hours. Elsa will move over water where the Sea Surface Temperatures are near 28°C. The center of Tropical Storm Elsa will pass just south of Haiti and just north of Jamaica. Elsa will move more slowly during the next 24 hours. It will move into a region where the upper level winds are weak and there will be less vertical wind shear. Tropical Storm Elsa could intensify back to a hurricane on Saturday night.

Tropical Storm Elsa will move south of the subtropical high pressure system over the Atlantic Ocean during the next 18 hours. The high will continue to steer Tropical Storm Elsa toward the west-northwest, but Elsa is likely to more more slowly. An upper level trough over the eastern U.S. is forecast to weaken the high pressure system on Sunday. When the high weakens, then Tropical Storm Elsa will move more toward the northwest. On its anticipated track the center of Tropical Storm Elsa will pass just to the south of the southwestern coast of Haiti. The center of Tropical Storm Elsa could pass north of Jamaica and be near eastern Cuba by Sunday morning. Elsa could approach the Florida Keys on Monday. Elsa will cause gusty winds and locally heavy rain over parts of Haiti, Jamaica and Cuba.
