Tropical Depression Karl Drops Heavy Rain on Southern Mexico

Tropical Depression Karl dropped heavy rain over parts of southern Mexico on Saturday morning. At 5:00 a.m. EDT on Saturday the center of Tropical Depression Karl was located at latitude 18.6°N and longitude 93.0°W which put it about 95 miles (150 km) east-northeast of Coatzacoalcos, Mexico. Karl was moving toward the southwest at 5 m.p.h. (8 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 1007 mb.

The center of Tropical Depression Karl made landfall on the coast of Mexico between Coatzacoalcos and Ciudad del Carmen on Saturday morning. Thunderstorms were occurring in bands in the southern part of Karl’s circulation. Those thunderstorms were dropping heavy rain over western Tabasco and southeastern Veracruz. Heavy rain is likely to cause flash floods in some locations. The circulation in the lower levels of Tropical Depression Karl will continue to weaken as it moves farther inland, but thunderstorms will continue to drop heavy rain over the region during the next few hours.

Tropical Storm Karl Moves South Toward Mexico

Tropical Storm Karl moved south toward Mexico on Thursday. At 5:00 p.m. EDT on Thursday the center of Tropical Storm Karl was located at latitude 20.9°N and longitude 93.5°W which put it about 195 miles (315 km) north-northeast of Coatzacoalcos, Mexico. Karl was moving toward the south-southeast 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 was in effect for the portion of the coast from Alvarado to Ciudad del Carmen, Mexico.

Even though the surface pressure at the center of Tropical Storm Karl decreased by two millibars on Thursday, the maximum sustained wind speed also decreased. The circulation around Karl pulled some drier air into the western part of the tropical storm. In addition, an upper level trough over the eastern U.S. produced west-northwesterly winds that blew toward the top of Karl’s circulation. Those winds caused moderate vertical wind shear. The drier air and the wind shear caused the strongest thunderstorms to occur in bands in the southern and eastern parts of Tropical Storm Karl. Bands in the northern and western parts of Karl consisted primarily of showers and lower clouds. Storms near the center of Karl’s circulation generated upper level divergence that pumped mass away to the east of the tropical storm. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Tropical Storm Karl will move through an environment marginally favorable for intensification during the next 24 hours. Karl will move over water where the Sea Surface Temperatures are near 29˚C. The upper level trough over the eastern U.S. will continue to produce westerly winds that will blow toward the top of Tropical Storm Karl. Those winds will cause moderate vertical wind shear. Moderate vertical wind shear and drier air in the western side of Karl’s circulation will inhibit intensification. The intensity of Tropical Storm Karl could fluctuate during the next 24 hours, but Karl is likely to remain a tropical storm.

Tropical Storm Karl will move around the southern part of a surface high pressure system that extends from the north central U.S. over the Gulf of Mexico. The high pressure system will push Karl toward the south during the next 36 hours. On its anticipated track, Tropical Storm Karl will make landfall on the coast of Mexico between Coatzacoalcos and Paraiso on Friday night. Karl will bring gusty winds and locally heavy rain to the coastal parts of Tabasco and Veracruz when it makes landfall. Heavy rain could cause flash floods in some locations.

Tropical Depression Agatha Drops Heavy Rain on Southern Mexico

Former Hurricane Agatha dropped heavy rain on southern Mexico on Tuesday. Agatha weakened to a tropical depression on Tuesday morning as it moved farther inland over southern Mexico. At 8:00 a.m. EDT on Tuesday the center of Tropical Depression Agatha was located at latitude 17.0°N and longitude 95.3°W which put it about 55 miles (90 km) north of Salina Cruz, Mexico. Agatha was moving toward the northeast at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1004 mb.

Tropical Depression Agatha dropped heavy rain on parts of Oaxaca, Chiapas, Veracruz and Tabasco on Tuesday morning. The lower levels of the circulation of former Hurricane Agatha weakened steadily on Tuesday as it moved farther inland over south Mexico. However, the circulation in the middle and upper levels of Agatha remained well organized. Microwave satellite images showed a well defined center of circulation in the middle levels. Bands of strong thunderstorms were present in the eastern half of Tropical Depression Agatha. Those bands were dropping locally heavy rain over parts of southern Mexico. Bands in the western half of Agatha’s circulation consisted primarily of showers and lower clouds.

An upper level trough over northern Mexico will steer the middle and upper parts of Tropical Depression Agatha toward the northeast during the next 36 hours. Bands in the eastern half of Agatha will continue to drop locally heavy rain over southern Mexico, the Yuacatan Peninsula and parts of Honduras. The heavy rain could cause flash floods in some locations. The middle and upper parts of Tropical Depression Agatha could emerge over the Bay of Campeche or Northwestern Caribbean Sea on Wednesday or Thursday. The remnants of Agatha could contribute to the formation of a tropical cyclone or subtropical cyclone later this week.

Tropical Depression Three Strengthens Into Tropical Storm Cristobal

Former Tropical Depression Three strengthened into Tropical Storm Cristobal on Tuesday.  At 12:15 p.m. EDT on Tuesday the center of Tropical Storm Cristobal was located at latitude 19.3°N and longitude 92.7°W which put it about 75 miles (120 km) northwest of Ciudad del Carmen, Mexico.  Cristobal was moving toward the southwest at 3 m.p.h. (5 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 1004 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Campeche to Puerto de Veracruz, Mexico

An Air Force Reserve Hurricane Hunter plane investigating former Tropical Depression Three on Tuesday found sustained winds of 40 m.p.h. (65 km/h) and the National Hurricane Center designated the system as Tropical Storm Cristobal.  The formation of Tropical Storm Cristobal on June 2 is the earliest date for the formation on the third named storm over the Atlantic Basin (including the Caribbean Sea and Gulf of Mexico) in the historical record.

The reconnaissance plane found that the circulation around Tropical Storm Cristobal was continuing to get better organized.  More thunderstorms were forming near the center of circulation.  Bands of showers were revolving around the center of Cristobal.  Storms near the center were generating upper level divergence which was pumping mass away to the east of the tropical storm.  Winds to tropical storm force extended out 40 miles (65 km) from the center of circulation.

Tropical Storm Cristobal will move through an environment favorable for intensification during the next 12 to 24 hours.  Cristobal will move over water where the Sea Surface Temperature is near 29°C.  It will move under the western side of an upper level ridge centered over the western Caribbean Sea.  The ridge will produce southerly winds which will blow toward the top of the circulation.  Those winds will cause some vertical wind shear, but the shear will not be great enough to prevent intensification.  Tropical Storm Cristobal is likely to strengthen during the next 12 to 24 hours.

Tropical Storm Cristobal will move around the northwestern part of a larger counterclockwise circulation sometimes called a Central American Gyre (CAG).  The CAG will steer Cristobal toward the southwest during the next few hours.  Tropical Storm Cristobal will move more toward the south on Tuesday night.  The larger CAG will slowly contract around the circulation of Cristobal during the next several days.  Tropical Storm Cristobal will meander slowly near the south coast of the Bay of Campeche while the CAG contracts.  Eventually, a subtropical high pressure system over the western Atlantic Ocean will steer Cristobal northward toward the U.S.

Tropical Storm Cristobal will mix cooler water to the surface while it meanders over the southern Bay of Campeche.  The cooler water will reduce the energy available to Cristobal and the tropical storm could weaken during the middle of the week.  Tropical Storm Cristobal will weaken even more if the center of circulation moves over land.  Cristobal will drop heavy rain over Campeche, Tabasco and eastern Veracruz.  Prolonged heavy rain is likely to cause flash floods in some locations.

Tropical Depression Three Develops Over Bay of Campeche

Tropical Depression Three developed over the Bay of Campeche on Monday afternoon.  At 5:00 p.m. EDT on Monday the center of Tropical Depression Three was located at latitude 19.6°N and longitude 91.2°W which put it about 55 miles (90 km) north-northeast of Carmen, Mexico.  The depression was moving toward the west-northwest at 7 m.p.h. (11 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 1007 mb.

The government of Mexico issued a Tropical Storm Warning for the portion of the coast from Campeche to Puerto de Veracruz.  

The remnants of the center of circulation of former Tropical Storm Amanda moved northward across Honduras and emerged over the eastern Bay of Campeche on Monday afternoon.  The National Hurricane Center designated the system as Tropical Depression Three and initiated advisories on the system.

More thunderstorms began to form on the northern side of Tropical Depression Three after the center of circulation moved over the eastern Bay of Campeche.  More thunderstorms were developing near the center.  Bands of showers and thunderstorms that included the remnants of the the circulation of former Tropical Storm Amanda were revolving around the center of the depression.

Tropical Depression Three will move through an environment favorable for intensification during the next 24 hours.  The depression will move over water where the Sea Surface Temperature is near 29°C.  It will move under the western side of an upper level ridge over the northwestern Caribbean Sea.  The ridge will produce northerly winds which will blow toward the top of the depression.  Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification.  Tropical Depression Three is likely to intensify into a tropical storm on Tuesday.

Tropical Depression Three will move around the northern side of a larger counterclockwise circulation sometimes called a Central American Gyre (CAG).  The CAG will steer the depression toward the west-northwest during the next 12 to 24 hours.   The depression could move toward the southwest on Tuesday when it moves around the northwestern part of the CAG.  On its anticipated track Tropical Depression Three could approach the coast around the southern Bay of Campeche.   The depression could drop heavy rain over Campeche, Tabasco and eastern Veracruz.  The heavy rain could cause flash floods in some locations.
