Tropical Storm Pilar Moves South of Mexico

Tropical Storm Pilar moved south of Mexico on Thursday evening. At 11:00 p.m. EDT on Thursday the center of Tropical Storm Pilar was located at latitude 10.7°N and longitude 99.2°W which put it about 465 miles (750 km) southwest of Salina Cruz, Mexico. Pilar was moving toward the west-southwest at 22 m.p.h. (35 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 998 mb.

There were not a lot of thunderstorms in the circulation around Tropical Storm Pilar on Thursday evening. A few thunderstorms persisted in a band on the northern side of the center of Pilar’s circulation. Bands in the other parts of Tropical Storm Pilar consisted primarily of showers and lower clouds. The circulation around Tropical Storm Pilar was small. Winds to tropical storm force extended out 80 miles (130 km) from the center of Pilar.

Tropical Storm Pilar will move through an environment that will be unfavorable for intensification during the next 24 hours. Pilar will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the Gulf of Mexico. The upper level ridge will produce northeasterly winds that will blow toward the top of Pilar’s circulation. A surface high pressure system that extends from the eastern U.S. across the Gulf of Mexico will produce strong northeasterly winds in the lower levels. The winds in the lower levels of the atmosphere will be stronger than the winds in the upper levels. The difference in wind speed will cause moderate vertical wind shear. The wind shear will inhibit intensification. In addition, the high pressure system will continue to pump cool dry air over the Gulf of Tehuantepec. The effects of the cool dry air and the moderate vertical wind shear will cause Tropical Storm Pilar to weaken on Friday.

Tropical Storm Pilar will move around the southern part of the surface high pressure system. The high pressure system will steer Pilar toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Storm Pilar will move farther away from Mexico on Friday.

Tropical Storm Pilar Moves West and Weakens

Tropical Storm Pilar moved toward the west and weakened on Wednesday. At 11:00 p.m. EDT on Wednesday the center of Tropical Storm Pilar was located at latitude 12.4°N and longitude 92.6°W which put it about 315 miles (505 km) southeast of Salina Cruz, Mexico. Pilar was moving toward the west 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.

Tropical Storm Pilar weakened on Wednesday. Many of the thunderstorms in Pilar’s circulation dissipated during the day. There were still a few thunderstorms in a band just west of the center of Tropical Storm Pilar. Bands in the other parts of Pilar’s circulation consisted primarily of showers and lower clouds. Winds to tropical storm force extended out 80 miles (130 km) from the center of Tropical Storm Pilar.

A large surface high pressure system over the eastern U.S. extended across the Gulf of Mexico to eastern Mexico. The high pressure system produced brisk northeasterly winds that transported cool dry air over the Gulf of Tehuantepec. The circulation around the western side of Tropical Storm Pilar appeared to pull some of the cool dry air into the tropical storm. The drier air reduced the relative humidity which caused the thunderstorms in Pilar to dissipate.

Tropical Storm Pilar will move through an environment that will be unfavorable for intensification during the next 24 hours. Pilar will move over water where the Sea Surface Temperatures are near 29°C. It will move under the southern part of an upper level ridge over the Northwestern Caribbean Sea. The upper level ridge will produce easterly winds that will blow toward the top of Pilar’s circulation. The surface high pressure system will continue to produce northeasterly winds in the lower levels. Easterly winds in the upper levels and northeasterly winds in the lower levels will cause moderate vertical wind shear. The wind shear will inhibit intensification. In addition, the high pressure system will continue to pump cool dry air over the Gulf of Tehuantepec. The effects of the cool dry air and the moderate vertical wind shear will cause Tropical Storm Pilar to continue to weaken on Thursday.

Tropical Storm Pilar will move around the southern part of the surface high pressure system. The high pressure system will steer Pilar toward the west-southwest during the next 24 hours. On its anticipated track, Tropical Storm Pilar will remain south of Mexico on Thursday.

Bonnie Intensifies to a Hurricane South of Mexico

Former Tropical Storm Bonnie intensified to a hurricane over the Eastern North Pacific Ocean on Sunday night. At 11:00 p.m. EDT on Sunday the center of Hurricane Bonnie was located at latitude 13.2°N and longitude 95.5°W which put it about 210 miles (335 km) south of Salina Cruz, Mexico. Bonnie was moving toward the west-northwest at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 987 mb.

A larger, ragged eye appeared at the center of Hurricane Bonnie on Sunday night. 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 were revolving around the core of Hurricane Bonnie. Storms near the core generated upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 25 miles (40 km) in the eastern side of Bonnie’s circulation. Winds to tropical storm force extended out 80 miles (130 km) from the center of Bonnie.

Hurricane Bonnie will move through an environment favorable for intensification during the next 36 hours. Bonnie will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the southern side of an upper level ridge over the Eastern North Pacific Ocean. The ridge will produce easterly winds that will blow toward the top of Bonnie’s circulation. Those winds will cause some vertical wind shear, but the shear will not be enough to prevent intensification. Hurricane Bonnie will intensify during the next 36 hours. A period of rapid intensification could occur after the ring of thunderstorms around the eye becomes fully formed. Bonnie could strengthen to a major hurricane early next week.

Tropical Storm Bonnie will move south of a high pressure system over Mexico. The high pressure system will steer Bonnie toward the west-northwest during the next 36 hours. On its anticipated track Tropical Storm Bonnie will remain south of the coast of Mexico.

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.

A Hurricane Warning was in effect for the portion of the coast from Salina Cruz to Lagunas de Chacahua, Mexico. A Hurricane Watch was in effect for the portion of the coast from Salina Cruz to Barra de Tonala. Tropical Storm Warnings were in effect for the portions of the coast from Lagunas de Chacahua to Punta Maldonado and from Salina Cruz to Boca de Pijijiapan, Mexico.

Hurricane Agatha maintained its intensity until it made landfall on the southern coast of Mexico just to the west of Puerto Angel on Sunday afternoon. A reconnaissance aircraft reported a circular eye with a diameter of 35 miles (55 km) at the center of Hurricane Agatha. The eye was also visible on satellite images. The eye was surrounded by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms. The ring of thunderstorms was weaker south of the eye. Bands of showers and thunderstorms were revolving around the core of Agatha. Storms near the core generated strong upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Agatha increased slightly in size on Sunday. Winds to hurricane force extended out 25 miles (40 km) from the center of Agatha’s circulation. Winds to tropical storm force extended out 90 miles (145 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Agatha was 17.8. The Hurricane Size Index (HSI) was 8.8 and the Hurricane Wind Intensity Size Index (HWISI) was 26.6.

An upper level trough over northern Mexico will steer Hurricane Agatha toward the northeast during the next 24 hours. On its anticipated track, Hurricane Agatha will move inland over Oaxaca. The center of Agatha could pass northwest of Tehuantepec and Salina Cruz on Monday night. Hurricane Agatha will bring strong winds and locally heavy rain to Oaxaca. Heavy rain is likely to cause flash floods in some locations. Agatha could produce a storm surge of ten feet (three meters) along portions of the coast of Oaxaca. Hurricane Agatha could cause localized serious damage.

The lower part of Hurricane Agatha’s circulation will weaken quickly when it moves over mountains in southern Mexico. The upper level trough over northern Mexico will steer the middle and upper parts of Agatha’s circulation toward the northeast during the next 24 hours. The middle and upper parts of Hurricane Agatha could emerge over the Bay of Campeche or northwest Caribbean Sea in a couple of days. Those parts of Agatha’s circulation could contribute to the development of a tropical or subtropical cyclone over the Gulf of Mexico, northwest Caribbean Sea or western Atlantic Ocean later this week.

Hurricane Agatha Nears Southern Mexico

Hurricane Agatha neared southern Mexico on Monday morning. At 8:00 a.m. EDT on Monday the center of Hurricane Agatha was located at latitude 15.1°N and longitude 97.3°W which put it about 65 miles (105 km) southwest of Puerto Angel, Mexico. Agatha was moving toward the northeast at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 110 m.p.h. (175 km/h) and and there were wind gusts to 130 m.p.h. (210 km/h). The minimum surface pressure was 964 mb.

A Hurricane Warning was in effect for the portion of the coast from Salina Cruz to Lagunas de Chacahua, Mexico. A Hurricane Watch was in effect for the portion of the coast from Salina Cruz to Barra de Tonala. Tropical Storm Warnings were in effect for the portions of the coast from Lagunas de Chacahua to Punta Maldonado and from Salina Cruz to Boca de Pijijiapan, Mexico.

Hurricane Agatha did not change much during Sunday night. A small circular eye was present at the center of Hurricane Agatha. 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 Agatha. Storms near the core generated strong upper level divergence that pumped mass away from the hurricane.

Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Agatha was 19.2. The Hurricane Size Index (HSI) was 7.3 and the Hurricane Wind Intensity Size Index (HWISI) was 26.5. The intensity of Hurricane Agatha was the same as the intensity of Hurricane Sally when Sally hit northwest Florida in 2020. Agatha was smaller than Sally was.

Hurricane Agatha will move through an environment favorable for intensification during the next few hours. Agatha will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the center of an upper level ridge over the Eastern North Pacific Ocean. The upper level winds are weak near the center of the ridge and there will be little vertical wind shear. Hurricane Agatha could strengthen a little before it reaches Mexico. An upper level trough over Baja California will approach Agatha as the hurricane makes landfall on the coast of Mexico. The upper level trough will produce westerly winds that will blow toward the top of Agatha’s circulation. Those winds will cause the vertical wind shear to increase. More wind shear will make the environment less favorable for intensification. The circulation around Hurricane Agatha could pull drier air over Mexico into the western part of Agatha. More vertical wind shear and drier air could cause Hurricane Agatha to start to weaken just prior to landfall.

The upper level trough over Baja California will steer Agatha toward the northeast more quickly on Monday. On its anticipated track, Hurricane Agatha will make landfall on the coast of Mexico near Puerto Escondido and Puerto Angel in a few hours. Hurricane Agatha will bring strong winds and locally heavy rain to Oaxaca and Chiapas. Heavy rain is likely to cause flash floods in some locations. Agatha could produce a storm surge of ten feet (three meters) along portions of the coast of Oaxaca. Hurricane Agatha could cause localized serious damage.

Tropical Storm Warnings were in effect for the portions of the coast from Lagunas de Chacahua to Punta Maldonado and from Salina Cruz to Boca de Pijijiapan, Mexico.

Tropical Storm Agatha strengthened on Saturday. However, microwave satellite images suggested that the center of circulation in the middle troposphere could be a little to the northeast of the center at the surface. A ring of thunderstorms surrounded much of the center in the middle troposphere and the center at the surface could reform under the mid-tropospheric center. Thunderstorms around the center in the middle troposphere generated upper level divergence that pumped mass away from the tropical storm. Some drier air over Mexico appeared to get pulled into the northwestern part of Agatha’s circulation. Bands in the northwestern part of Tropical Storm Agatha consisted primarily of showers and lower clouds. Bands of thunderstorms were in the southern and eastern parts of Agatha. Winds to tropical storm force extended out 70 miles (110 km) from the center of Tropical Storm Agatha.

Tropical Storm Agatha will move through an area favorable for intensification during the next 36 hours. Agatha will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the center of an upper level ridge over the Eastern North Pacific Ocean. The upper level winds are weak near the center of the ridge and there will be little vertical wind shear. Tropical Storm Agatha will intensify during the next 36 hours and it could strengthen to a hurricane on Sunday. Agatha could undergo a period of rapid intensification if the center at the surface reforms under the center in the middle troposphere and an inner core with an eye and an eyewall develop fully.

Tropical Storm Agatha will move around the western part of a high pressure system over Central America and the Eastern North Pacific Ocean. The high pressure system will steer Agatha toward the north during the next 12 hours. Agatha will move toward the northeast on Sunday night and Monday when it moves around the northwestern part of the high pressure system. On its anticipated track, Tropical Storm Agatha will move approach the coast of Mexico near Puerto Escondido and Puerto Angel on Monday afternoon. Tropical Storm Agatha is likely to be a hurricane when it approaches Mexico. There is a chance Agatha could be a major hurricane when it nears the coast of Mexico.
