Tropical Storm Gordon Forms East of Leeward Islands

Tropical Storm Gordon formed east of the Leeward Islands on Friday morning.  At 11:00 a.m. EDT on Friday the center of Tropical Storm Gordon was located at latitude 19.4°N and longitude 38.6°W which put the center about 1640 miles (2650 km) east of the Leeward Islands.  Gordon was moving toward the west-northwest at 12 m.p.h. (19 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 1006 mb.

A low pressure system over the Atlantic Ocean between the Leeward Islands and the Cabo Verde Islands strengthened on Friday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Gordon.  The distribution of thunderstorms in Gordon’s circulation was asymmetrical.  Thunderstorms were occurring in bands in the eastern side of Tropical Storm Gordon.  Bands in the western side of Gordon’s circulation consisted primarily of showers and lower clouds.

The distribution of winds speeds around Tropical Storm Gordon was also asymmetrical.  Winds to tropical storm force extended out 60 miles (95 km) in the eastern side of Gordon’s circulation.  The winds in the western side of Tropical Storm Gordon were blowing at less than tropical storm force.

Tropical Storm Gordon will move through an environment mostly unfavorable for intensification during the next 24 hours.  Gordon will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southeastern part of an upper level ridge over the subtropical Atlantic Ocean.  The upper level ridge will produce northeasterly winds that will blow toward the top of Gordon’s circulation.  Those winds will cause moderate vertical wind shear.  Gordon will also move through a region of very dry air.  The dry air will make if difficult for new thunderstorms to develop.  Tropical Storm Gordon could weaken to a tropical depression during the weekend because of the dry air.

Tropical Storm Gordon will move around the south side of the subtropical high pressure system will steer Gordon to the west during the next 24 hours.  On its anticipated track, Tropical Storm Gordon will remain far to the east of the Leeward Islands during the weekend.

Elsewhere, the circulation of former Hurricane Francine was meandering over the Lower Mississippi River Valley.  At 11:00 a.m. EDT on Friday the center of Tropical Depression Francine was located at latitude 35.8°N and longitude 91.4°W which put the center about 80 miles (130 km) north-northeast of Little Rock, Arkansas.  Francine was moving toward the southeast at 3 m.p.h. (5 km/h).  The maximum sustained wind speed was 15 m.p.h. (25 km/h) and there were wind gusts to 25 m.p.h. (40 km/h).  The minimum surface pressure was 1005 mb.

Beryl Brings Rain and Storms to Central U.S.

Former Hurricane Beryl is bringing rain and thunderstorms to parts of the central U.S. on Tuesday.  Beryl weakened to a tropical depression on Monday night as it moved farther inland. At 11:00 a.m. EDT on Tuesday the center of Tropical Depression Beryl was located at latitude 35.8°N and longitude 91.2°W which put the center about 35 miles (55 km) west-southwest of Jonesboro, Arkansas.  Beryl was moving toward the northeast at 25 m.p.h. (40 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1004 mb.

A day after Hurricane Beryl hit the coast of Texas and caused over 2.5 million customers to lose electricity, Beryl is bringing rain and thunderstorms to parts of the central U.S.  The center of the surface circulation of former Hurricane Beryl is located over northeastern Arkansas.  Thunderstorms are starting to form in bands over Alabama, western Tennessee and western Kentucky.  Steady light to moderate rain is falling over Missouri, central Illinois and central Indiana.

An upper level trough over the central U.S. will steer Tropical Depression Beryl toward the northeast during the next 24 hours.  On its anticipated track the center of Beryl’s circulation will move from northeastern Arkansas to northern Indiana.

Tropical Depression Beryl will drop heavy rain over parts of the Middle Mississippi River Valley and Lower Great Lakes.  The heaviest rain is likely to fall in southeastern Missouri, central and eastern Illinois, northwestern Indiana and southern Michigan.

Flood Watches are in effect for northern Arkansas, central and southern Missouri, Illinois, far western Kentucky, northern Indiana and southern Michigan.

The circulation around the eastern side of Tropical Depression Beryl could generate enough low level wind shear for rotation in thunderstorms.  Some thunderstorms could produce tornadoes.  The U.S. National Weather Service Storm Prediction Center (SPC) is indicating an Enhanced Risk of Severe Weather for the area stretching from Cincinnati, Ohio through Louisville, Kentucky to Evansville, Indiana.

The center of Hurricane Beryl made landfall on the coast of Texas at Matagorda early on Monday morning.  Beryl was intensifying at the time of landfall.  The maximum sustained wind speed in Hurricane Beryl was 80 m.p.h. (130 km/h) at the time of landfall.  A circular eye with a diameter of 32 miles (52 km) was present at the center of Beryl’s circulation at the time of landfall.

The strongest winds in Hurricane Beryl were occurring in the eastern half of Beryl’s circulation.  At the time of landfall winds to hurricane force extended out 45 miles (75 km) in the eastern side of Beryl.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Hurricane Beryl.

The Hurricane Intensity Index (HII) for Hurricane Beryl at the time of landfall was 11.5.  The Hurricane Size Index (HSI) was 10.3 and the Hurricane Wind Intensity Size Index (HWISI) was 21.8.  Hurricane Beryl was not quite as strong as Hurricane Dolly was when Dolly hit South Texas in 2008.  Beryl was a little smaller that Dolly was.

The eye of Hurricane Beryl passed directly over Matagorda, Texas.  A weather station at Matagorda, Texas (EMAT2) reported a sustained wind speed of 68 m.p.h. (110 km/h) when the northern part of the eyewall passed over the station.  The station also reported a wind gust of 86 m.p.h. (139 km/h).  The station reported a surface pressure of 980 mb when the eye of Hurricane Beryl was over it.

A weather station at Freeport, Texas (FPST2) reported a sustained wind speed of 75 m.p.h. (120 km/h) and a wind gust of 87 m.p.h. (141 km/h).

A weather station at the North Jetty Entrance to Galveston Bay (GNJT2) reported a sustained wind speed of 72 m.p.h. (117 km/h) and a wind gust of 82 m.p.h. (132 km/h).

After Hurricane Beryl made landfall on the coast of Texas, the center of Beryl’s circulation passed just to the west of Houston.  The eastern side of Beryl’s eyewall passed over Houston.  Beryl brought strong winds and heavy rain to the area around Houston.

A weather station at Houston Hobby Airport reported a sustained wind speed of 58 m.p.h. (94 km/h) and a wind gust of 84 m.p.h. 135 km/h).  The weather station also reported 4.15 inches (105 mm) of rain.

A weather station at Houston Intercontinental Airport reported a sustained wind speed of 59 m.p.h. (95 km/h) and a wind gust of 82 m.p.h. (132 km/h).  The station also reported 4.31 inches of rain.

The strong winds in Hurricane Beryl caused widespread electricity outages in east Texas.  There were reports of 2.5 million customers without electricity.

The strong winds in Hurricane Beryl caused a storm surge along the coast of Texas.  There were reports of water level rises of 5 feet (1.5 meters) at multiple locations along the coast.

Tropical Storm Beryl will move under the southeastern part of an upper level trough over the Central U.S.  The upper level trough will steer Beryl toward the north-northeast during the next 12 hours.  On its anticipated track, Tropical Storm Beryl will move over northeast Texas later today.  The upper level trough will steer Beryl toward the northeast on Tuesday.  Beryl will move over Arkansas on Tuesday morning.

Tropical Storm Beryl will continue to weaken gradually as it moves farther inland.  Beryl will continue to produce strong winds over east Texas during the next few hours.  Widespread minor wind damage is likely to occur.  There are also likely to be additional electricity outages.  Tropical Storm Beryl could drop up to 8 inches (200 mm) of rain on some locations.   Heavy rain is likely to cause flooding.  Flood Watches are in effect for parts of eastern Texas.  Flood Watches are also in effect for parts of southeastern Oklahoma, southwestern Arkansas and northwestern Louisiana.  Tropical Storm Beryl will continue to cause a storm surge of up to 5 feet (1.5 meters) along the coast until the wind speeds decrease when Beryl moves farther away.

Heavy rain was falling over parts of eastern Texas.  Heavy rain was falling in Houston and Galveston.

Hurricane Beryl will move around the western part of a high pressure system over the southeastern U.S.  The high pressure system will steer Beryl toward the north during the next 12 hours. Hurricane Beryl will start to move toward the northeast on Monday night.  On its anticipated track, the center of Hurricane Beryl will pass over Bay City, Texas.  The center of Beryl will pass just to the west of Houston in a few hours.

Hurricane Beryl will start to weaken gradually as the center of Beryl’s circulation moves farther inland.  Beryl will bring strong winds and heavy rain to parts of eastern Texas.  Hurricane Beryl will be capable of causing regional minor damage.  The strongest winds will be in the eastern side of Hurricane Beryl.  Beryl will bring strong winds to Galveston and Houston.  The strong winds are likely to cause electricity outages.

Hurricane Beryl could drop up to 10 inches (250 mm) of rain on some locations.   Heavy rain is likely to cause flooding.  Flood Watches are in effect for parts of eastern Texas.  Flood Watches are also in effect for parts of southeastern Oklahoma, southwestern Arkansas and northwestern Louisiana.  Hurricane Beryl could also cause a storm surge of up to 10 feet (3 meters) where the wind pushes water toward the coast.

 

Beryl Strengthens Back to a Hurricane

Former Tropical Storm Beryl strengthened back to a hurricane on Sunday night as it neared the coast of Texas.  At 12:00 a.m. EDT on Monday the center of Hurricane Beryl was located at latitude 27.7°N and longitude 95.7°W which put the center about 65 miles (105 km) south-southeast of Matagorda, Texas.   Beryl was moving toward the north-northwest 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 985 mb.

A Hurricane Warning was in effect for the portion of the coast from Mesquite Bay to Port Bolivar, Texas.

A Tropical Storm Warning was in effect for the portion of the coast from Mesquite Bay to Port Mansfield, Texas.  A Tropical Storm Warning was also in effect for the portion of the coast from Port Bolivar to Sabine Pass, Texas.

A Storm Surge Warning was in effect for the portion of the coast from Mesquite Bay to Sabine Pass, Texas.

Former Tropical Storm Beryl strengthened back to a hurricane as it neared the coast of Texas on Sunday night.  Beryl strengthened slowly but steadily on Sunday night.  The inner end of a rainband wrapped around the center of Beryl’s circulation.  A circular eye with a diameter of 45 miles (75 km) was at the center of Hurricane Beryl.  The eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms revolved around the center of Hurricane Beryl.  Storms near the center of circulation generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease slowly.

The circulation around Hurricane Beryl became more symmetrical on Sunday.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Beryl’s circulation.

Hurricane Beryl will move through an environment that will be favorable for intensification during the next few hours.  Beryl will move over water where the Sea Surface Temperatures are near 30°C.  It will move under an upper level ridge over the Gulf of Mexico.  The upper level winds are weak in the ridge and there will be be little vertical wind shear.  Hurricane Beryl will continue to intensify during the next few hours.  There could be a brief period of more rapid intensification if an inner core with an eye and and eyewall develops fully.

Hurricane Beryl will move around the southwestern part of a high pressure system over the southeastern U.S.   The high pressure system will steer Beryl toward the north during the next 24 hours.   On its anticipated track, Hurricane Beryl will make landfall on the coast of Texas on Monday.  The center of Beryl’s circulation will make landfall between Matagorda and Galveston, Texas.

Hurricane Beryl will bring strong winds and heavy rain to parts of eastern Texas.  The strong winds are likely to cause power outages.  Beryl could bring strong winds to Galveston and Houston.  Up to 10 inches (250 mm) of rain could fall in some locations.  Heavy rain is likely to cause flooding.  Flood Watches are in effect for parts of eastern Texas.  Flood Watches are also in effect for parts of southeastern Oklahoma, southwestern Arkansas and northwestern Louisiana.  Hurricane Beryl could also cause a storm surge of up to 10 feet (3 meters) where the wind pushes water toward the coast.

 

 

 

Hurricane Delta Brings Wind and Rain to Louisiana

Hurricane Delta brought wind and rain to Louisiana on Friday evening.  At 8:00 p.m. EDT on Friday the center of Hurricane Delta was located at latitude 30,0°N and longitude 93.0°W which put it about 25 miles west-southwest of Jennings, Louisiana.  Delta was moving toward the north-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 90 m.p.h. (145 km/h) and there were wind gusts to 105 m.p.h. (165 km/h).  The minimum surface pressure was 971 mb.

A Hurricane Warning was in effect for the portion of the coast from High Island, Texas to Morgan City, Louisiana.  Tropical Storm Warnings were in effect for the portions of the coast from San Luis Pass to High Island, Texas and from Morgan City, Louisiana to the Mouth of the Pearl River.  The Tropical Storm Warning includes New Orleans, Lake Pontchartrain and Lake Maurepas.

According the National Hurricane Center the center of Hurricane Delta officially made landfall on the coast of Louisiana near Creole.  The maximum sustained wind speed at the time of landfall was 100 m.p.h. (160 km/h).  Winds to hurricane force extended out 40 miles (65 km) from the center of circulation.  Winds to tropical storm force extended out 160 miles (260 km).

Hurricane Delta weakened on Friday while moved toward the coast of Louisiana.  An upper level trough produced southwesterly winds which blew toward the top of Delta.  Those winds caused moderate vertical wind shear.  The circulation around Hurricane Delta pulled drier air about the southern side of the hurricane.  In addition, Delta moved over cooler water near the coast of Louisiana.  The combination of shear, drier air and cooler water caused the circulation to weaken on Friday afternoon.

Even though it weakened, Hurricane Delta brought strong winds and rain to Louisiana.  A weather station in Lake Charles, Louisiana reported a sustained wind speed of 64 m.p.h. (103 km/h) and a wind gust of 95 m.p.h. (153 km/h).  A weather station at Lake Arthur, Louisiana reported a sustained wind speed of 77 m.p.h. (125 km/h) and a wind gust of 96 m.p.h. (154 km/h).  A weather station at Cameron, Louisiana reported a sustained wind speed of 58 m.p.h. (93 km/h) and a wind gust of 78 m.p.h. (128 km/h).  A weather station at Port Arthur, Texas reported a wind gust of 71 m.p.h. (114 km/h).

Winds blowing around the eastern side of Hurricane Delta pushed water toward the coast and cause a storm surge.  A station at Freshwater Canal Locks in Louisiana reported a water level rise of 8 feet (2.4 meters).  Delta also dropped heavy rain over parts of Louisiana.  Flash Flood Warnings were issued for some of the areas around Lake Charles and Lafayette, Louisiana.

Hurricane Delta will weaken steadily as it moves farther inland.  The upper level trough will steer Delta toward the northeast during the next several days.  On its anticipated track Delta will move across Louisiana toward southwest Tennessee.  The center of Delta will pass near Alexandria and Monroe, Louisiana.  Flash Flood Watches were in effect for Louisiana, northern Mississippi. southeastern Arkansas, and southwestern Tennessee.

Laura Weakens to Tropical Storm over Arkansas

Former Hurricane Laura weakened to a tropical storm over Arkansas on Thursday afternoon.  At 2:00 p.m. EDT on Thursday the center of Tropical Storm Laura was located at latitude 32.9°N and longitude 92.8°W which put it about 25 miles (40 km) west-southwest of El Dorado, Arkansas.  Laura was moving toward the north-northeast at 15 m.p.h. (24 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 988 mb.

All coastal Tropical Storm Warnings have been discontinued.

Hurricane Laura caused significant wind damage over southwestern Louisiana.  The largest concentration of damage appeared to be around Lake Charles, Louisiana.  There were reports that the dome for the weather radar at the National Weather Service office in Lake Charles sustained heavy damage.  The Automated Surface Observing Station (ASOS) at Lake Charles reported a peak wind speed of 133 m.p.h. (215 km/h).  There were also reports of widespread power outages in Louisiana and eastern Texas.

Former Hurricane Laura gradually weakened as it moved inland over Louisiana.  The circulation around Tropical Storm Laura was still well organized.  However, drier air was wrapping around the western and southern sides of the circulation.  The heavier rains and stronger winds were north and east of the center of Laura.  Flash Flood Watches were in effect for parts of Arkansas, western Tennessee, western Kentucky and extreme southeastern Missouri.

Tropical Storm Laura will turn more toward the east when it reaches southern Missouri on Friday.  Westerly winds in the middle latitudes will carry Laura toward the east coast of the U.S.  Tropical Storm Laura could bring gusty winds and locally heavy rain to West Virginia on Saturday.

Powerful Hurricane Laura Makes Landfall in Southwest Louisiana

Powerful Hurricane Laura made landfall in southwest Louisiana on Wednesday night.  At 2:00 a.m. EDT on Thursday the center of Hurricane Laura was located at latitude 29.8°N and longitude 93.3°W which put it about 30 miles (50 km) south-southwest of Lake Charles, Louisiana.  Laura was moving toward the north at 15 m.p.h. (24 km/h).  The maximum sustained wind speed was 150 m.p.h. (240 km/h) and there were wind gusts to 175 m.p.h. (280 km/h).  The minimum surface pressure was 938 mb.

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

The center of Hurricane Laura officially made landfall near Cameron, Louisiana on Tuesday night.  Hurricane Laura was the strongest hurricane on record to make landfall on the coast of southwest Louisiana.  Laura was stronger than Hurricane Rita was when Rita made landfall in the same area in September 2005.  The Hurricane Intensity Index (HII) for Hurricane Laura was 31.6.  The Hurricane Size Index (HSI) was 19.6 and the Hurricane Wind Intensity Size Index (HWISI) was 51.2.  Hurricane Laura was capable of causing widespread extensive damage.

A NOAA National Ocean Service weather station at Calcasieu Pass measured a sustained wind speed of 93 m.p.h. (150 km/h) and a wind gust of 127 m.p.h. (204 km/h) during the passage of the northern eyewall.  The station also recorded a water rise of over 10 feet (3 meters).  The National Weather Service station at the Lake Charles airport measured a wind gust of 104 m.p.h. (167 km/h) during the passage of an inner rainband.  There were numerous reports of power outages.

Hurricane Laura will move inland over western Louisiana on Thursday.  The center of Laura will move over southern Arkansas by Thursday night.  Hurricane Laura will continue to cause a significant storm surge along the coast of Louisiana on Thursday morning.  Laura could produce hurricane force winds in Alexandria, Louisiana.  It could bring strong tropical storm force winds to Shreveport and Monroe.  Hurricane Laura will also drop heavy rain over Louisiana and parts of Arkansas.  Flash floods could occur in some locations.

Hurricane Laura Intensifies to Cat. 4

Hurricane Laura rapidly intensified to Category 4 on the Saffir-Simpson Scale on Wednesday.  At 2:00 p.m. EDT on Wednesday the center of Hurricane Laura was located at latitude 27.3°N and longitude 92.5°W which put it about 200 miles (320 km) south-southeast of Lake Charles, Louisiana.  Laura was moving toward the northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 140 m.p.h. (225 km/h) and there were wind gusts to 170 m.p.h. (275 km/h).  The minimum surface pressure was 952 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 continued to intensify rapidly on Wednesday morning.  The eye became more circular and well defined.  The ring of thunderstorms around the eye strengthened and the highest wind speeds were occurring in that ring of storms.   Storms near the core of Laura generated strong upper level divergence which pumped large quantities of mass away from the hurricane.  The continued removal of mass allowed a further rapid decrease in surface pressure.

Hurricane Laura grew into a large hurricane on Wednesday.  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 of Laura.  The Hurricane Intensity Index (HII) for Hurricane Laura was 28.3.  The Hurricane Size Index (HSI) was 19.1 and the Hurricane Wind Intensity Size Index (HWISI) was 47.4.  Hurricane Laura was capable of causing widespread significant damage.

Hurricane Laura could strengthen during the next few hours.  Laura will move over water where the Sea Surface Temperature is near 30°C.  There is a possibility that Hurricane Laura could intensify to Category 5 on the Saffir-Simpson Scale.  When Hurricane Laura nears the coast of western Louisiana, it will be 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 the vertical wind shear to increase and that could stop the intensification of Hurricane Laura.

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 start to move towards the north when it reaches the western end of the high.  On its anticipated track Hurricane Laura will make landfall south of Lake Charles, Louisiana in 8 to 10 hours.  After it makes landfall, Laura will move north over western Louisiana.

Hurricane Laura is a strong, extremely dangerous hurricane.  It is capable of causing widespread significant damage.  Laura will be stronger than Hurricane Rita was when Rita hit the same area in 2005.  Hurricane Laura will cause a storm surge of 15 to 20 feet (5 to 7 meters) near and to the east of where the center makes landfall.  Large sections of the southwest coast of Louisiana south of Interstate 10 will go underwater.  Hurricane Laura will bring hurricane force winds to much of western Louisiana and to extreme east Texas.  Widespread power outages are likely.  Hurricane Laura will drop heavy rain over parts of western Louisiana, eastern Texas and Arkansas.  Flash floods could result from the heavy rain

Tropical Depression Cristobal Brings Rain to Lower Mississippi River Valley

Tropical Depression Cristobal brought rain to the lower Mississippi River Valley on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Depression Cristobal was located at latitude 34.8°N and longitude 92.8°W which put it about 10 miles (15 km) west of Little Rock, Arkansas.  Cristobal was moving toward the north-northwest at 17 m.p.h. (28 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 994 mb.

Tropical Depression Cristobal moved northward across Louisiana and Arkansas on Monday.  Steadier rain fell in the northern part of the circulation around Cristobal.  Diverging air from a surface high pressure system east of the Great Lakes converged with the circulation around the northern side of Tropical Depression Cristobal to produce rising motion.  The rising motion produced the steadier rain.  Thunderstorms in bands in the southern and eastern parts of Cristobal dropped locally heavy rain over parts of Louisiana, Mississippi and Alabama.  Jackson, Mississippi received 2.49 inches (6.3 cm) of rain.  Little Rock, Arkansas received 1.49 inches (3.8 cm) of rain.

Tropical Depression Cristobal will move around the western side of a high pressure system.  The high will steer Cristobal toward the north during the next several days.  The circulation around Tropical Depression Cristobal retained tropical characteristics on Monday night.  Radiosonde data from Little Rock and Jackson, Mississippi showed that there was still a warm core in the middle troposphere.  Cristobal is forecast to make a gradual transition to an extratropical cyclone during the next 24 to 36 hours.  The circulation could strengthen during the extratropical transition and a Gale Warning has been issued for Lake Michigan.  Flood Watches were also in effect for locations from Mississippi to Wisconsin.
