Tropical Storm Nicholas Brings Wind and Rain to Houston

Tropical Storm Nicholas brought wind and rain to Houston on Tuesday morning. At 8:00 a.m. EDT on Tuesday the center of Tropical Storm Nicholas was located at latitude 29.5°N and longitude 95.5°W which put it about 15 miles (25 km) south-southwest of Houston, Texas. Nicholas was moving toward the north-northeast at 8 m.p.h. (13 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 999 mb.

A Tropical Storm Warning was in effect for the portion of the coast from San Luis Pass, Texas to Cameron, Louisiana. The Tropical Storm Warning included Galveston and Port Arthur.

Tropical Storm Nicholas brought gusty winds and locally heavy rain to the area around Houston on Tuesday morning. Houston Intercontinental Airport was reporting a sustained wind speed of 33 m.p.h. (54 km/h) and a wind gust of 51 m.p.h. (82 km/h). The airport was reporting moderate rain. Moderate to heavy rain was also falling over southeast Texas and the southern half of Louisiana. A band of showers and thunderstorms extended from near Port Arthur, Texas southward over the Gulf of Mexico. Other bands of showers and thunderstorms were over southern Louisiana and southwestern Mississippi. Winds to tropical storm force extended out 125 miles (200 km) on the eastern side of Nicholas’ circulation. Winds to tropical storm force extended out 60 miles on the western side of the circulation.

Tropical Storm Nicholas will move slowly toward the east-northeast during the next 36 hours. The circulation around Nicholas will weaken gradually. Tropical Storm Nicholas will continue to drop locally heavy rain over southeast Texas, southern Louisiana and southern Mississippi. Flash Flood Watches are in effect for those locations.

Nicholas Strengthens to a Hurricane near Texas Coast

Former Tropical Storm Nicholas strengthened to a hurricane near the Texas coast on Monday night. At 11:00 p.m. EDT on Monday the center of Hurricane Nicholas was located at latitude 28.4°N and longitude 95.8°W which put it about 45 miles (75 km) southwest of Freeport, Texas. Nicholas was moving toward the north-northeast at 10 m.p.h. (16 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. (145 km/h). The minimum surface pressure was 988 mb.

A Hurricane Waring was in effect for the portion of the coast from Port O’Connor to Freeport, Texas. A Hurricane Watch was in effect for the portion of the coast from Freeport to San Luis Pass, Texas. Tropical Storm Warnings were in effect for the portions of the coast from Port Aransas to Port O’Connor, Texas and from Freeport to Sabine Pass, Texas. The Tropical Storm Warning included Galveston.

Former Tropical Storm Nicholas strengthened to a hurricane on Monday night. An upper level ridge over the Gulf of Mexico enhanced upper level divergence to the northeast of Nicholas. The enhanced upper level divergence pumped away more mass and the surface pressure at the center of Nicholas decreased to 988 mb on Monday evening. The decreased pressure increased the pressure difference and a larger pressure gradient force caused the wind speed to gradually increase to hurricane force.

The circulation around Hurricane Nicholas was still asymmetrical. Drier air was wrapping around the southern side of Nicholas’ circulation and the precipitation was falling in the north half of the hurricane. The strongest winds were occurring in the eastern half of Hurricane Nicholas. Winds to hurricane force extended out 25 miles (40 km) in the northeastern quadrant of Nicholas. Winds to tropical storm force extended out 115 miles (185 km) on the eastern side of Hurricane Nicholas. Winds to tropical storm force extended out 45 miles on the western side of the hurricane.

Hurricane Nicholas will move around the western end of a high pressure system that extends over the Gulf of Mexico. The high pressure system will steer Nicholas toward the north-northeast during the next 24 hours. On its anticipated track the center of Hurricane Nicholas could make landfall near Freeport, Texas in a few hours. Hurricane Nicholas will bring strong winds to the coast of Texas between Matagorda and Port Arthur. Scattered power outages are likely. Nicholas will drop heavy rain over parts of southeastern Texas and over Louisiana on Tuesday. Flash floods could occur in some locations. Southerly winds blowing on the east side of Hurricane Nicholas will push water toward the coast. Those winds could cause a storm surge of up to 7 feet (2 meters). The water level will rise along the coast of southwest Louisiana too.

Tropical Storm Nicholas Nears Texas Coast

Tropical Storm Nicholas neared the coast of Texas on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Storm Nicholas was located at latitude 26.4°N and longitude 96.8°W which put it about 140 miles (225 km) south of Port O’Connor, Texas. Nicholas was moving toward the north at 12 m.p.h. (19km/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 1002 mb.

A Hurricane Watch was in effect for the portion of the coast from Port Aransas to San Luis Pass, Texas. A Tropical Storm Warning was in effect for the portion of the coast from the Mouth of the Rio Grande River to Sabine Pass, Texas. The Tropical Storm Warning included Corpus Christi and Galveston.

The center of Tropical Storm Nicholas reorganized several times on Monday. Each time a new center formed farther to the north-northeast. The new centers formed on the southern sides of clusters of stronger thunderstorms. The inner end of a rainband appeared to be wrapping around the northern side of the most recent center of circulation. Other bands of stronger thunderstorms were occurring north and east of the center of Nicholas. Bands to the south and west of the center consisted primarily of showers and lower clouds. The strongest winds were occurring in the eastern half of Tropical Storm Nicholas. Winds to tropical storm force extended out 115 miles (185 km) on the eastern side of Nicholas. The winds in the western half of the circulation were blowing at less than tropical storm force.

Tropical Storm Nicholas will move through an environment favorable for intensification during the next 12 hours. Nicholas will move over water where the Sea Surface Temperatures are near 30˚C. It will move between and upper level trough over northern Mexico and an upper level ridge over the Gulf of Mexico. The upper trough and ridge will produce southerly winds that will blow toward the top of Nicholas’ circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The upper level low will move west and weaken during the next 12 hours. The upper level ridge will extend northwest over Tropical Storm Nicholas. When the ridge extends over Nicholas the upper level winds will weaken. When the upper level winds weaken, the vertical wind shear will decrease. Tropical Storm Nicholas will strengthen when that occurs. If a more well defined center develops and persists in the middle of Nicholas, the it could strengthen more quickly. There is a chance that Nicholas could intensify to a hurricane later on Monday.

Tropical Storm Nicholas will move around the western side of a high pressure system that extends over the Gulf of Mexico. The high will steer Nicholas toward the north during the next 12 hours. On its anticipated track Tropical Storm Nicholas will approach the central coast of Texas on Monday night. Nicholas will bring gusty winds and locally heavy rain to coastal areas of northeast Texas on Monday night. The strongest winds and the heaviest rain will occur before the center of Tropical Storm Nicholas makes landfall. The strongest winds will occur on the eastern side of Nicholas’ circulation. Scattered power outages could occur along the Upper Texas Coast and in southwestern Louisiana. Tropical Storm Nicholas could also cause a storm surge of up to 7 feet (2 meters) along portions of the coast. Nicholas will move toward the northeast on Tuesday. Locally heavy rain will fall over Louisiana. Flash floods could occur in some locations.

Tropical Storm Nicholas Prompts Hurricane Watch for Texas

A potential threat posed by Tropical Storm Nicholas prompted the issuance of a Hurricane Watch for a portion of the Texas coast on Sunday. At 11:00 p.m. EDT on Sunday the center of Tropical Storm Nicholas was located at latitude 22.5°N and longitude 95.5°W which put it about 260 miles (415 km) south-southeast of the Mouth of the Rio Grande River. Nicholas was moving toward the north at 2 m.p.h. (3 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were’ wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1007 mb.

A Hurricane Watch was in effect for the portion of the coast from Port Aransas to Freeport, Texas. A Tropical Storm Warning was in effect for the portion of the coast from Barra el Mezquital, Mexico to High Island Texas. The Tropical Storm Warning included Corpus Christi and Galveston. A Tropical Storm Watch was in effect for the portion of the coast from High Island to Sabine Pass, Texas.

The circulation around Tropical Storm Nicholas was poorly organized. There was a broad center of circulation in the middle of Nicholas. Several smaller cyclonic circulations were revolving around inside the broad center. Many of the thunderstorms were occurring in bands in the northern half of Tropical Storm Nicholas. Bands in the southern half of Nicholas consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 115 miles (185 km) in the northeastern quadrant of Tropical Storm Nicholas. The winds in the other parts of Nicholas’ circulation were blowing at less than tropical storm force.

Tropical Storm Nicholas will move through an environment favorable for intensification during the next 24 hours. Nicholas will move over water where the Sea Surface Temperatures are near 30˚C. It will move between and upper level low over northern Mexico and an upper level ridge over the northwestern Caribbean Sea. The upper low and ridge will produce southerly winds that will blow toward the top of Nicholas’ circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The upper level low will move west and weaken on Monday. The upper level ridge will extend west over Tropical Storm Nicholas. When the ridge extends over Nicholas the upper level winds will weaken. When the upper level winds weaken, the vertical wind shear will decrease. Tropical Storm Nicholas will strengthen when that occurs. If a more well defined center develops in the middle of Nicholas, the it could strengthen more quickly. There is a chance that Nicholas could intensify to a hurricane later on Monday.

Tropical Storm Nicholas will move around the western side of a high pressure system that extends over the Gulf of Mexico. The high will steer Nicholas toward the north-northwest during the next 24 hours. On its anticipated track Tropical Storm Nicholas will approach the coast near the Mouth of the Rio Grande River on Monday. Nicholas will bring gusty winds and locally heavy rain to coastal areas of northern Mexico and east Texas on Monday. Tropical Storm Nicholas could also cause a storm surge of up to 7 feet (2 meters) along portions of the coast. It is possible that a new center of circulation could develop closer to the thunderstorms in the northern half of Tropical Storm Nicholas. If a new center develops farther to the north, that could increase the threat to northeastern Texas and western Louisiana.

Tropical Storm Nicholas Forms over Southwest Gulf of Mexico

Tropical Storm Nicholas formed over the southwestern Gulf of Mexico on Sunday morning. At 11:00 a.m. EDT on Sunday the center of Tropical Storm Nicholas was located at latitude 20.5°N and longitude 94.8°W which put it about 405 miles (645 km) south-southeast of the Mouth of the Rio Grande River. Nicholas was moving toward the north-northwest at 13 m.p.h. (20 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were’ wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1008 mb.

A Tropical Storm Warning was issued for the portion of the coast from Barra el Mezquital, Mexico to Port Aransas, Texas. A Tropical Storm Watch was issued for the portion of the coast from Port Aransas to High Island, Texas.

An Air Force Reserve Hurricane Hunter reconnaissance plane found sustained winds of tropical storm force in a low pressure system over the southwestern Gulf of Mexico on Sunday morning and the National Hurricane Center designated the system as Tropical Storm Nicholas. The circulation around Tropical Storm Nicholas was still organizing. Thunderstorms began to form near the center of Nicholas. Thunderstorms were also developing in bands revolving around the center of circulation. Winds to tropical storm force extended out 100 miles (160 km) in the northeastern quadrant of Tropical Storm Nicholas. The winds in the other parts of the circulation were blowing at less than tropical storm force.

Tropical Storm Nicholas will move through an environment favorable for intensification during the next 24 hours. Nicholas will move over water where the Sea Surface Temperatures are near 30˚C. It will move between and upper level low over northern Mexico and an upper level ridge over the northwestern Caribbean Sea. The upper low and ridge will produce south-southwesterly winds that will blow toward the top of Nicholas’ circulation. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. The upper level winds are forecast to weaken on Monday and Tropical Storm Nicholas could strengthen more quickly when that occurs. There is a chance that Nicholas could intensify to a hurricane on Monday.

Tropical Storm Nicholas will move around the western side of a high pressure system that extends over the Gulf of Mexico. The high will steer Nicholas toward the north-northwest during the next 24 hours. On its anticipated track Tropical Storm Nicholas will approach the coast near the Mouth of the Rio Grande River on Monday. Nicholas will bring gusty winds and locally heavy rain to coastal areas of northern Mexico and southern Texas on Monday. Tropical Storm Nicholas could also cause a storm surge of up to 7 feet (2 meters) along portions of the coast.

Hurricane Laura Rapidly Intensifies into a Major Hurricane

Hurricane Laura rapidly intensified into a major hurricane during the overnight hours.  At 8:00 a.m. EDT on Wednesday the center of Hurricane Laura was located at latitude 26.4°N and longitude 91.4°W which put it about 280 miles (450 km) south-southeast of Lake Charles, Louisiana.  Laura was moving toward the northwest at 15 m.p.h. (24 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 963 mb.

A Hurricane Warning was in effect for the portion of the coast from San Luis, Pass, Texas to Intracoastal City, Lousiana.  Tropical Storm Warnings were in effect for the portions of the coast from Sargent, Texas to San Luis Pass and from Intracoastal City to the Mouth of the Mississippi River.

Hurricane Laura strengthened rapidly over the warm water in the Central Gulf of Mexico during the overnight hours.  An eye with a diameter of 30 miles (50 km) formed at the center of Laura.  A ring of strong thunderstorms surrounded the eye and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Laura.   Storms near the core were generating strong upper level divergence which was pumping large quantities of mass away from the hurricane in all directions.  The removal of mass allowed the surface pressure to decrease quickly, which caused Laura to rapidly intensify.

The size of the circulation around Hurricane Laura also increased during the overnight hours.  Winds to hurricane force extended out 70 miles (110 km) from the center of circulation).  Winds to tropical storm force extended out 175 miles (280 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Laura was 20.6.  The Hurricane Size Index (HSI) was 19.1 and the Hurricane Wind Intensity Size Index (HWISI) was 39.7.  Hurricane Laura was capable of causing widespread major damage.

Hurricane Laura will continue to move through an environment favorable for intensification today.  Laura will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will little vertical wind shear.  Hurricane Laura could strengthen to Category 4 on the Saffir-Simpson Scale.  When Hurricane Laura approaches the coast it will get closer to an upper level trough over Texas and Oklahoma.  The trough will produce southwesterly winds which will blow toward the top of Laura.  Those winds will cause some vertical wind shear and Hurricane Laura could start to weaken just before it makes landfall.

Hurricane Laura will move around the western end of a subtropical high pressure system that extends from the Atlantic Ocean over the Gulf of Mexico.  Laura will move toward the north-northwest as it approaches the western end of the high.  On its anticipated track Hurricane Laura will make landfall near the border between Louisiana and Texas tonight.

Hurricane Laura will be capable of causing major damage over western Louisiana and eastern Texas.  Strong winds could cause widespread power outages.  Wind blowing water toward the coast will cause a storm surge of 10 to 15 feet (3 to 5 meters) near and to the east of where the center makes landfall.  Laura will drop locally heavy rain when it moves inland and flash floods could occur in some locations.

The wind speed in Hurricane Laura will be similar to the winds in Hurricane Harvey when Harvery made landfall on the coast of Texas in 2017.  Laura will be bigger than Harvey was.  The winds in Hurricane Laura could be stronger than the winds were in Hurricane Rita when Rita hit the same area in 2005.  However, Rita had intensified to Category 5 on the Saffir-Simpson Scale, but it was weakening when it made landfall.  Laura will not be as big as Rita was in 2005.

Hurricane Laura Strengthens over Central Gulf of Mexico

Hurricane Laura strengthened over the central Gulf of Mexico on Tuesday night.  At 11:00 p.m. EDT on Tuesday the center of Hurricane Laura was located 25.2°N and longitude 89.5°W which put it about 405 miles (655 km) southeast of Lake Charles, Louisiana.  Laura was moving toward the west-northwest at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 110 m.p.h. (175 km/h).  The minimum surface pressure was 978 mb.

A Hurricane Warning was in effect for the portion of the coast from San Luis Pass, Texas to Intracoastal City, Louisana.  Tropical Storm Warnings were in effect for the portions of the coast from Sargent to San Luis Pass, Texas and from Intracoastal City, Louisiana to the Mouth of the Mississippi River.  A Tropical Storm Warning was also in effect for Houston, Texas.

Hurricane Laura intensified over the warm water in the central Gulf of Mexico on Tuesday night.  An eye was visible intermittently on satellite imagery.  The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Laura.  Storms near the core generated upper level divergence which pumped mass away from the hurricane.  The removal of large quantities of mass was causing the pressure to decrease more rapidly.

The area of Laura with hurricane force winds expanded on Tuesday night.  Hurricane force winds extended out 45 miles (75 km) from the center of circulation.  Winds to tropical storm force extended out 175 miles (280 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Laura was 13.9.  The Hurricane Size Index (HSI) was 13.7 and the Hurricane Wind Intensity Size Index (HWISI) was 27.6.

Hurricane Laura will move through an environment favorable for intensification on Wednesday.  Laura will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Laura will strengthen on Wednesday and it could intensify rapidly.  Laura will strengthen into a major hurricane and it could reach Category 4 on the Saffir-Simpson Scale.

Hurricane Laura will move around the western end of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Laura toward the northwest during the next 12 to 18 hours.  The hurricane will turn toward the north when it reaches the western end of the high.  On its anticipated track Hurricane Laura will landfall near the border between Louisiana and Texas on Wednesday night.

Hurricane Laura will be a major hurricane when it makes landfall.  It will be capable of causing regional major wind damage.  Hurricane Laura will also cause a storm surge of 10 to 15 feet (3 to 5 meters) near and to the east of where the center makes landfall.  Locally heavy rain could cause flash floods in parts of east Texas and Louisiana when Hurricane Laura moves inland.

Laura Strengthens into a Hurricane

Former Tropical Storm Laura strengthened into a hurricane on Tuesday morning.  At 8:15 a.m. EDT on Tuesday the center of Hurricane Laura was located at latitude 23.4°N and longitude 86.4°W which put it about 625 miles (1005 km) southeast of Lake Charles, Louisiana.  Laura was moving toward the west-northwest at 17 m.p.h. (28 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. (145 km/h).  The minimum surface pressure was 991 mb.

A Hurricane Watch was in effect for the portion of the coast from San Luis Pass, Texas to Morgan City, Louisiana.  The Hurricane Watch includes Galveston, Texas.  Houston, Texas is under a Tropical Storm Watch.  Tropical Storm Watches are also in effect for the portions of the coast from Freeport to San Luis Pass, Texas and from Morgan City, Louisiana to the Mouth of the Mississippi River.

A Hurricane Hunter aircraft found on Tuesday morning that former Tropical Storm Laura had strengthened into a hurricane.  The distribution of thunderstorms around Laura was asymmetrical.  Many of the thunderstorms were occurring in bands in the southern half of the circulation and near the center of Laura.  Bands in the northern half of the circulation consisted primarily of showers and lower clouds.  Storms near the center of circulation were generating upper level divergence which was pumping mass away from the hurricane.  Winds to tropical storm force extended out 175 miles (280 km) on the eastern side of Laura.  Winds to tropical storm force extended out 100 miles (160 km) on the western side of the hurricane.

Hurricane Laura will move through an environment favorable for intensification during the next 30 hours.  Laura will move over water where the Sea Surface Temperature is near 30°C.  It will move under an upper level high where the upper level winds are weak.  There will be little vertical wind shear.  Hurricane Laura will continue to intensify.  When an inner core is fully formed with an eye and an eyewall, Laura could strengthen more rapidly.  Laura will likely strengthen into a major hurricane over the Gulf of Mexico.

Hurricane Laura will move around the western end of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Laura toward the west-northwest during the next 12 hours.  Laura will turn more toward the northwest as it approaches the western end of the high.  On its anticipated track the center of Hurricane Laura will approach the portion of the coast between Freeport, Texas and Lake Charles, Louisiana on Wednesday night.

Hurricane Laura is likely to be a major hurricane when it approaches the coast.  In addition to the strong winds, Laura could create a storm surge of over 10 feet (3 meters) along a portion of the coast. Heavy rain could also cause flash floods in some locations.

Tropical Storm Laura Prompts Hurricane Watch for Northwest Gulf Coast

The potential threat from Tropical Storm Laura prompted the issuance of a Hurricane Watch for a portion of the northwest Gulf Coast on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Laura was located at latitude 21.7°N and longitude 82.2°W which put it about 40 miles (65 km) east of the Isle of Youth, Cuba.  Laura was moving toward the west-northwest at 20 m.p.h. (32 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 1001 mb.

A Hurricane Watch was issued for the portion of the coast from Port Bolivar, Texas to Morgan CIty, Louisiana.  A Tropical Storm Watch was issued for the portion of the coast from Morgan City to the Mouth of the Mississippi River.  A Tropical Storm Warning remained in effect for the Florida Keys from Craig Key to Key West and the Dry Tortugas.  Tropical Storm Warnings were also in effect for the Cuban provinces of Ciego de Avila, Sancti Spiritus, Villa Carla, Cienfuegos, Matanzas, Mayabeque, La Habana, Artemisa, Pinar del Rio and Isle of Youth.

The appearance of Tropical Storm Laura did not change much on Monday afternoon.  Many of the stronger thunderstorms were occurring in bands in the southern half of the circulation.  bands in the northern half of the circulation consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 175 miles (280 km) from the center on the eastern side of Laura.  Winds were blowing at less than tropical storm force in the western half of the circulation.

Tropical Storm Laura will move near Cuba for another 12 to 18 hours.  So, the flow of air across Cuba is likely to continue to disrupt the northern half of the circulation during the time period.  When Laura moves over the Gulf of Mexico on Tuesday , it will move into an environment favorable for intensification.  Tropical Storm Laura will move over water where the Sea Surface Temperature is near 30°C.  It will move into an area where the upper level winds will be weak and there will be little vertical wind shear.  Tropical Storm Laura will intensify into a hurricane over the Gulf of Mexico and it could strengthen into a major hurricane.

Tropical Storm Laura will move around the western end of a subtropical high pressure system over the Atlantic Ocean.  The high will steer Laura toward the west-northwest during the next 12 to 24hours.  Laura will move more toward the north when it reaches the western end of the high.  On its anticipated track Tropical Storm Laura could make landfall on the northwest coast of the Gulf of Mexico on Wednesday night.  Laura could be a major hurricane when it makes landfall.

Elsewhere,  the center of Tropical Storm Marco was very close to the Mouth of the Mississippi River.  At 5:00 p.m. EDT on Monday the center of Tropical Storm Marco was located at latitude 29.0°N and longitude 88.9°W which put it about 15 miles (25 km) east-southeast of the Mouth of the Mississippi River.  Marco was moving toward the northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1008 mb.  All coastal watches and warnings for Tropical Storm Marco have been discontinued.

Tropical Storm Imelda Forms Along Upper Texas Coast

Tropical Storm Imelda formed along the Upper Texas coast on Tuesday.  At 2:00 p.m. EDT on Tuesday the center of Tropical Storm Imelda was located at latitude 29.0°N and longitude 95.3°W which put it near Freeport, Texas.  Imelda was moving toward the north at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1005 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Sargent to Port Bolivar, Texas.

A small low pressure system over the northwestern Gulf of Mexico exhibited greater organization on satellite and radar images on Tuesday.  When a surface weather station reported a sustained wind speed of 40 m.p.h. (65 km/h), the National Hurricane Center designated the system as Tropical Storm Imelda.  The winds to tropical storm force were occurring southeast of the center of circulation.  Winds to tropical storm force extended out about 45 miles (75 km) in the southeastern quadrant of Tropical Storm Imelda.

Tropical Storm Imelda will move around the western end of a warm high pressure system over the southeastern U.S.  The high will steer Imelda slowly toward the north during the next several days.  On its anticipated track Tropical Storm Imelda will move slowly inland over east Texas.  Although Imelda will cause a small storm surge along the coast around the northwestern Gulf of Mexico, locally heavy rain will pose a much greater risk.  Southeasterly winds blowing around the eastern side of Tropical Storm Imelda will transport very moist air over parts of eastern Texas.  Over a foot of rain (0.33 meters) could fall in some locations where rain bands linger.  Flash Flood Watches have been issued for a number of counties around Houston and Galveston.

Elsewhere over the Atlantic Ocean, Hurricane Humberto moved closer to Bermuda and Tropical Depression Ten formed east of the Lesser Antilles.  At 2:00 p.m. EDT on Tuesday the center of Hurricane Humberto was located at latitude 30.8°N and longitude 72.9°W which put it about 490 miles (785 km) west-southwest of Bermuda.  Humberto was moving toward the east-northeast at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).  The minimum surface pressure was 961 mb.

A Hurricane Watch and a Tropical Storm Warning were in effect for Bermuda.

At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Ten was located at latitude 12.9°N and longitude 44.9°W which put it about 1165 miles (1870 km) east-southeast of the Leeward Islands.  It was moving toward the west-northwest at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1007 mb.  The depression is forecast to strengthen into a hurricane while it moves toward the northern Leeward Islands.
