Tropical Storm Bertha Near Texas/Louisiana Border

The center of Tropical Storm Bertha moved back inland near the border between Texas and Louisiana on Thursday afternoon.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Bertha was located at latitude 29.9°N and longitude 93.8°W which put the center about 20 miles (30 km) east of Port Arthur, Texas.  Bertha was moving toward the west at 10 m.p.h. (16 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 1004 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Morgan City, Louisiana to Sargent, Texas.

Tropical Storm Bertha was bringing gusty winds to southern Louisiana and eastern Texas on Thursday afternoon.  However, the strongest winds were in the southeastern part of Bertha’s circulation.  Those winds were occurring over the Gulf of Mexico.

The distribution of wind speeds around Tropical Storm Bertha was very asymmetrical.  Winds to tropical storm force extended out 160 miles (260 km) in the southern part of Bertha’s circulation.  Winds to tropical storm force only extended out 25 miles (40 km) in the northern side of Tropical Storm Bertha.

The heaviest rain was falling in thunderstorms located in bands in the southwestern periphery of Tropical Storm Bertha.  Those thunderstorms were over the Gulf of Mexico east of Texas.  Light to moderate rain was falling over southern Louisiana and eastern Texas from showers and a few thunderstorms in bands closer to the low level center of Bertha’s circulation.

Tropical Storm Bertha will move around the southern side of a high pressure system that is over the Southern Plains.  The high pressure system will steer Bertha toward the west-southwest during the next 24 hours. On its anticipated track, the center of Tropical Storm Bertha will move inland over eastern and south central Texas.

Tropical Storm Bertha will produce gusty winds over eastern and south central Texas as it moves inland.  Thunderstorms, primarily south of the center of Bertha’s circulation, could produce heavy rain in some locations.  Heavy rain could cause flash floods in some places.

Tropical Storm Bertha Moves Across Southeast Louisiana

Tropical Storm Bertha moved across southeastern Louisiana on Wednesday evening.  At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Bertha’ was located at latitude 29.4°N and longitude 91.1°W which put the center about 75 miles (120 km) southwest of New Orleans, Louisiana.  Bertha was moving toward the west-southwest at 12 m.p.h. (19 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 1002 mb.

A Tropical Storm Warning is in effect for the portion of the coast from the Mississippi/Alabama border to Sargent, Texas.  A Tropical Storm Warning is in effect for New Orleans.  A Tropical Storm Warning is in effect for Lake Pontchartrain.

Strong northeasterly winds in the upper levels of the atmosphere appeared to be blowing the middle and upper parts of Tropical Storm Bertha to the southwest of the surface circulation.  The center of the surface circulation was south-southeast of Morgan City, Louisiana.  Thunderstorms were still occurring in bands in the southwestern part of the surface circulation around Tropical Storm Bertha.  Bands in the other parts of Bertha’s circulation consisted primarily of showers and lower clouds.  It is possible that a new center of circulation could develop closer to the area of showers and thunderstorms.

The strongest winds were occurring in the southeastern part of Tropical Storm Bertha.  Those winds were occurring over the Gulf of Mexico.  Winds to tropical storm force extended out 160 miles (260 km) in the southern side of Bertha’s circulation.  Winds to tropical storm force only extended out 60 miles (95 km) in the northern side of Tropical Storm Bertha.

Tropical Storm Bertha will move through an environment that will be unfavorable for intensification during the next 18 hours.  Bertha will move over water where the Sea Surface Temperatures are near 29°C.  It will move under southeastern part of an upper level ridge that is centered over the South Central U.S.  The upper level ridge will produce strong northeasterly winds that will blow across the top of Bertha’s circulation.  Those upper level winds will continue to cause strong vertical wind shear.  Tropical Storm Bertha is likely to continue to weaken during the next 18 hours unless a new center of circulation forms near the thunderstorms over the Gulf of Mexico.

Tropical Storm Bertha will move around the southern side of a high pressure system that is over the southern Mississippi River Valley.  The high pressure system will steer Bertha toward the west during the next 24 hours.  On its anticipated track, the center of Tropical Storm Bertha will move over eastern Texas south of Galveston on Thursday evening.

Tropical Storm Bertha will bring gusty winds to the northwestern Gulf Coast.  Bertha could drop locally heavy rain over parts of southern Louisiana and eastern Texas.

Tropical Storm Bertha Weakens

Tropical Storm Bertha weakened on Wednesday morning as it moved toward southeastern Louisiana.  At 2:00 p.m. EDT on Wednesday the center of Tropical Storm Bertha was located at latitude 29.9°N and longitude 89.1°W which put the center about 60 miles (95 km) east of New Orleans, Louisiana.  Bertha was moving toward the west-northwest at 7 m.p.h. (11 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 1000 mb.

A Tropical Storm Warning is in effect for the portion of the coast from the Alabama/Florida border to Morgan City, Louisiana.  A Tropical Storm Warning is in effect for New Orleans.  A Tropical Storm Warning is in effect for Lake Pontchartrain.

A Tropical Storm Watch is in effect for Lake Maurepas.   A Tropical Storm Watch is in effect for the portion of the coast from Morgan City to Sargent, Texas.

Tropical Storm Bertha weakened on Wednesday morning because of strong northeasterly winds in the upper troposphere.  Those winds were causing strong vertical wind shear, and the wind shear was causing Bertha to weaken.  The vertical wind shear was also affecting the structure of Tropical Storm Bertha.  Most of the bands revolving around the center of Bertha’s circulation consisted primarily of showers and lower clouds.  Thunderstorms were still occurring in bands in the far southwestern part of Tropical Storm Bertha.  There were no thunderstorms near the center of Bertha to generate upper level divergence.  Convergence of mass in the lower atmosphere was causing the surface pressure to increase.

Tropical Storm Berta was still producing sustained winds to tropical storm force.  Winds to tropical storm force extended out 105 miles (165 km) in the eastern side of Bertha’s circulation.  Winds to tropical storm force extended out 70 miles (110 km) in the western side of Tropical Storm Bertha.

Tropical Storm Bertha will move through an environment that will be unfavorable for intensification during the next 24 hours.  Bertha will move over water where the Sea Surface Temperatures are near 29°C.  It will move under southeastern part of an upper level ridge that is centered over the South Central U.S.  The upper level ridge will produce strong northeasterly winds that will blow across the top of Bertha’s circulation. Those upper level winds will continue to cause strong vertical wind shear.  Tropical Storm Bertha will continue to weaken during he next 24 hours.

Tropical Storm Bertha will move around the southern side of a high pressure system that is over the southern Mississippi River Valley.  The high pressure system will steer Bertha toward the west during the next 24 hours.  On its anticipated track, the center of Tropical Storm Bertha will move over southeastern Louisiana in a few hours.

Tropical Storm Bertha will bring gusty winds to the central Gulf Coast.  Since the strongest winds are in the southern part of Bertha’s circulation, those winds will remain over the Gulf of Mexico during the next 24 hours.  Bands on the northern side of Tropical Storm Bertha could drop locally heavy rain over parts of southern Alabama, southern Mississippi, and southern Louisiana. Bertha could also cause a storm surge of up to 4 feet (1 meter) along parts of the coast of southeastern Louisiana.

Tropical Storm Arthur Weakens

Former Tropical Storm Arthur weakened on Wednesday evening as it moved along the coast near Galveston, Texas.  At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Arthur was located at latitude 29.7°N and longitude 94.5°W which put the center about 35 miles (55 km) north-northeast of Galveston, Texas.  Arthur was moving toward the northeast at 9 m.p.h. (15 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 1000 mb.

An upper level trough over the central U.S. was producing westerly winds that were blowing across the top of Tropical Depression Arthur on Wednesday evening.  The upper level winds blew the tops off of many of the thunderstorms in Arthur.  A few thunderstorms were still occurring in bands in the eastern periphery of Arthur’s circulation.  The other bands revolving around the center of Arthur consisted primarily of showers and lower clouds.

Tropical Depression Arthur will move around the northwestern side of a high pressure system that extends from the western Atlantic Ocean to over the Gulf of Mexico.  The high pressure system will steer Arthur toward the northeast during the next 24 hours.  On its anticipated track, Tropical Depression Arthur will move near the border between Texas and Louisiana on Thursday.  Arthur will start to move toward the east by Friday.

Tropical Depression Arthur could interact with a stationary front to drop heavy rain over parts of the Southeast U.S.  Heavy rain could cause floods in some locations.

Flood Watches are in effect for southeast Texas, most of Louisiana, the southern half of Mississippi, central Alabama, Northwest Florida, and northern Georgia.

Tropical Storm Arthur Develops Near Texas Coast

Tropical Storm Arthur developed near the coast of Texas on Wednesday morning.  At 12:30 p.m. EDT on Wednesday the center of Tropical Storm Arthur was located at latitude 28.8°N and longitude 95.5°W which put the center about 40 miles (65 km) southwest of Galveston, Texas. Arthur was moving toward the northeast at 9 m.p.h. (15 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 999 mb.

A Tropical Storm Warning is in effect for the portion of the coast from Sargent, Texas to Morgan City Louisiana.

A low pressure system near the coast of Texas, formerly called Potential Tropical Cyclone One, strengthened on Wednesday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Arthur.

The strongest winds were occurring in bands in the eastern and northern sides of Tropical Storm Arthur.

A weather station in Galveston, Texas, (KGLS) reported a sustained wind speed of 39 m.p.h. (63 km/h) and a wind gust of 59 m.p.h. (95 km/h).

NOAA buoy 42035 which is east of Galveston, Texas reported a sustained wind speed of 45 m.p.h. (75 km/h) and a wind gust of 52 m.p.h. (83 km/h).

A weather station on oil platform Galveston 209A (KGVW) reported a sustained wind speed of 70 m.p.h. (113 km/h) and a wind gust of 80 m.p.h. (130 km/h).  It should be noted that the weather station is 121 feet (37 meters) above sea level.

The distribution of thunderstorms in Tropical Storm Arthur was asymmetrical.  Thunderstorms were occurring in bands in the eastern and northern parts of Arthur’s circulation.  Bands in the western and southern parts of Tropical Storm Arthur consisted primarily of showers and lower clouds.

The surface center of Tropical Storm Arthur appeared to be east of a low in the middle troposphere based on visible satellite loops.  The middle level low was producing southwesterly winds that were blowing toward the top of Arthur’s circulation.  Those winds were causing strong vertical wind shear.  The vertical wind shear was causing the asymmetrical distribution of thunderstorms.

The strongest winds were occurring in the bands of thunderstorms in the eastern and northern parts of Tropical Storm Arthur.  Winds to tropical storm force extended out 175 miles (280 km) in the eastern half of Arthur’s circulation.  Winds in the western half of Tropical Storm Arthur were blowing at less than tropical storm force.

Tropical Storm Arthur will move around the northwestern side of a high pressure system that extends from the western Atlantic Ocean to over the Gulf of Mexico.  The high pressure system will steer Arthur toward the northeast during the next 24 hours.  On its anticipated track, Arthur will move inland near the border between Texas and Louisiana in a few hours.

Tropical Storm Arthur will move through an environment that will be marginally favorable for intensification during the next few hours.  Arthur will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southern part of an upper level trough that is over the central U.S.  The upper level trough will produce westerly winds that will blow toward the top of Arthur’s circulation.  Those winds will cause strong vertical wind shear.  The vertical wind shear will inhibit development, but the wind shear may not be enough to prevent some intensification.  Tropical Storm Arthur could intensify during the next few hours before it makes landfall in Louisiana.

Tropical Storm Arthur will bring gusty winds and heavy rain to parts of the southeastern U.S.  Heavy rain is likely to cause floods in some locations.

Flood Watches are in effect for southeast Texas, most of Louisiana, the southern half of Mississippi, central Alabama, Northwest Florida, and northern Georgia.

Tropical Storm Arthur could also cause a storm surge of up to 4 feet (1 meter) along the coast of Louisiana.
