Tropical Storm Beatriz Develops Near Mexico

Tropical Storm Beatriz developed over the Eastern North Pacific Ocean near Mexico on Thursday afternoon. At 5:00 p.m. EDT on Thursday the center of Tropical Storm Beatriz was located at latitude 15.0°N and longitude 99.4°W which put it about 135 miles (220 km) south-southeast of Acapulco, Mexico. Beatriz 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 1004 mb.

A Hurricane Warning was in effect for the portion of the coast from Zihuatenajo to Playa Perula, Mexico. The Hurricane Warning included Manzanillo. A Hurricane Watch was in effect for the portion of the coast from Playa Perula to Cabo Corrientes, Mexico. A Tropical Storm Warning was in effect for the portion of the coast from Punta Maldonado to Zihuatenajo, Mexico. The Tropical Storm Warning included Acapulco. A Tropical Storm Watch was in effect for the portion of the coast from Cabo Corrientes to Punta Mita, Mexico.

Former Tropical Depression Two-E strengthened to Tropical Storm Beatriz over the Eastern North Pacific Ocean near Mexico on Thursday afternoon. A distinct low level center of circulation was evident on visible satellite images of Tropical Storm Beatriz. Bands of showers and thunderstorms were revolving around the center of Beatriz’ circulation. Storm near the center of circulation generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 45 miles (75 km) in the northeastern quadrant of Tropical Storm Beatriz. The winds in the other parts of Beatriz’ circulation were blowing at less than tropical storm force.

Tropical Storm Beatriz will move through an environment favorable for intensification during the next 24 hours. Beatriz will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southwestern part of an upper level ridge over Mexico and the southern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Tropical Storm Beatriz. However, the winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Tropical Storm Beatriz will intensify during the next 24 hours. Beatriz could intensify rapidly at times. Tropical Storm Beatriz could strengthen to a hurricane during the next 24 hours.

The upper level ridge over Mexico and the southern U.S. will steer Tropical Storm Beatriz toward the northwest during the next 36 hours. On its anticipated track, Tropical Storm Beatriz will move closer to the coast of Mexico. The center of Beatriz could be near Manzanillo by Friday evening. Beatriz could be a hurricane when it gets near Manzanillo. Bands in the northern side of Tropical Storm Beatriz could bring gusty winds and locally heavy rain to parts of the west coast of Mexico. Locally heavy rain could fall in parts of Oaxaca and Guerrero. Strong winds and locally heavy rain could affect Michoacan, Colima and Jalisco. Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian was churning south of Baja California. At 5:00 p.m. EDT on Thursday the center of Hurricane Adrian was located at latitude 16.4°N and longitude 110.7°W which put it about 450 miles (720 km) south of the southern tip of Baja California. Adrian was moving toward the west-northwest at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 85 m.p.h. (135 km/h) and there were wind gusts to 100 m.p.h. (160 km/h). The minimum surface pressure was 980 mb.

Mexico Issues Tropical Storm Watches and Warnings

The government of Mexico issued Tropical Storm Watches and Tropical Storm Warnings for the west coast of Mexico on Wednesday night. A Tropical Storm Warning was in effect for the portion of the coast from Punta Maldonado to Lazaro Cardenas, Mexico. The Tropical Storm Warning included Acapulco. A Tropical Storm Watch was in effect for the portion of the coast from Lazaro Cardenas to Manzanillo, Mexico.

A low pressure system over the Eastern North Pacific Ocean is forecast to strengthen to a tropical storm during the next several days as it moves near the coast of Mexico. The low pressure system was designated as Potential Tropical Cyclone Two-E on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Potential Tropical Cyclone Two-E was located at latitude 13.5°N and longitude 96.8°W which put it about 315 miles (505 km) southeast of Acapulco, Mexico. It was moving toward the northwest at 12 m.p.h. (19 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.

A low pressure system over the Eastern North Pacific Ocean southeast of Acapulco exhibited more organization on Wednesday night. The U.S. National Hurricane Center designated the system as Potential Tropical Cyclone Two-E. More thunderstorms formed in bands in the eastern side of Potential Tropical Cyclone Two-E. Storms near the center of circulation began to generate upper level divergence that pumped mass away from the system. Removal of mass will allow the surface pressure to decrease.

Potential Tropical Cyclone Two-E will move through an environment favorable for intensification during the next 36 hours. It will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southwestern part of an upper level ridge over Mexico and the southern U.S. The upper level ridge will produce easterly winds that will blow toward the top of Potential Tropical Cyclone Two-E. However, the winds in the lower levels of the atmosphere will also blow from the east. So, there will be little vertical wind shear. Potential Tropical Cyclone Two-E is likely to intensify during the next 36 hours. It could strengthen to a tropical depression during the next 12 hours. Potential Tropical Cyclone Two-E could intensify to a tropical storm during the next 24 hours.

The upper level ridge over Mexico and the southern U.S. will steer Potential Tropical Cyclone Two-E toward the northwest during the next 36 hours. On its anticipated track, Potential Tropical Cyclone Two-E will move closer to the coast of Mexico. It could be south of Acapulco on Thursday. Bands in the northern side of Potential Tropical Cyclone Two-E could bring gusty winds and locally heavy rain to parts of the west coast of Mexico. Locally heavy rain could fall in parts of Oaxaca, Guerrero and Jalisco. Heavy rain could cause flash floods in some locations.

Elsewhere over the Eastern North Pacific Ocean, Hurricane Adrian was spinning southwest of Manzanillo. At 11:00 p.m. EDT on Wednesday the center of Hurricane Adrian was located at latitude 15.4°N and longitude 109.0°W which put it about 395 miles (640 km) southwest of Manzanillo, Mexico. Adrian was moving toward the west at 6 m.p.h. (10 km/h). The maximum sustained wind speed was 80 m.p.h. (130 km/h) and there were wind gusts to 95 m.p.h. (150 km/h). The minimum surface pressure was 986 mb.

Tropical Depression Lester Brings Rain to Southern Mexico

Tropical Depression Lester brought rain to southern Mexico on Saturday afternoon. At 2:00 p.m. EDT on Saturday the center of Tropical Depression Lester was located at latitude 16.5°N and longitude 98.5°W which put it about 85 miles (135 km) east-southeast of Acapulco, Mexico. Lester was moving toward the north at 10 m.p.h. (16 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 1009 mb.

Former Tropical Storm Lester quickly weakened to a tropical depression after the center made landfall on the coast of Mexico east of Acapulco. The government of Mexico discontinued the tropical storm warnings and watches for the coast. Tropical Depression Lester is forecast to dissipate quickly as it moves farther inland over Mexico. Even though Lester will weaken quickly, bands in the eastern side of Lester’s circulation will drop locally heavy rain over parts of Guerrero and Oaxaca. 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.

Hurricane Agatha Makes Landfall Near Puerto Angel, Mexico

Hurricane Agatha made landfall near Puerto Angel, Mexico on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Hurricane Agatha was located at latitude 15.7°N and longitude 96.6°W which put it about 5 miles (10 km) west of Puerto Angel, Mexico. Agatha was moving toward the northeast at 8 m.p.h. (13 km/h). The maximum sustained wind speed was 105 m.p.h. (165 km/h) and and there were wind gusts to 125 m.p.h. (200 km/h). The minimum surface pressure was 974 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 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.

The circulation around Hurricane Agatha was small. Winds to hurricane force extended out 20 miles (30 km) from the center of Agatha’s circulation. 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.

Hurricane Agatha Rapidly Intensifies to Cat. 2

Hurricane Agatha rapidly intensified to Category 2 on the Saffir-Simpson Scale over the Eastern North Pacific Ocean south of Mexico on Sunday afternoon. At 5:00 p.m. EDT on Sunday the center of Hurricane Agatha was located at latitude 14.1°N and longitude 98.7°W which put it about 185 miles (290 km) southwest of Puerto Angel, Mexico. Agatha was moving toward the northeast at 1 m.p.h. (2 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.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance plane found that Hurricane Agatha had rapidly intensified to a Category 2 hurricane on the Saffir-Simpson Scale on Sunday afternoon. A small circular eye formed 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.

The circulation around Hurricane Agatha was small. Winds to hurricane force extended out 20 miles (30 km) from the center of Agatha’s circulation. Winds to tropical storm force extended out 115 miles (175 km) from the center of circulation. The Hurricane Intensity Index (HII) for Hurricane Agatha was 19.2. The Hurricane Size Index (HSI) was 7.2 and the Hurricane Wind Intensity Size Index (HWISI) was 26.4.

Hurricane Agatha will move through an environment favorable for intensification during the next 18 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. Hurricane Agatha is likely to intensify during the next 18 hours. An upper level trough over Baja California will approach Hurricane Agatha on Monday. 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.

Hurricane Agatha will move around the northwestern part of a high pressure system over Central America and the Eastern North Pacific Ocean. The high pressure system will steer Agatha toward the northeast on Sunday night. The upper level trough over Baja California will steer Agatha toward the northeast more quickly on Monday. On its anticipated track, Hurricane Agatha will move approach the coast of Mexico near Puerto Escondido and Puerto Angel during the middle of Monday. Agatha could be a major hurricane when it nears the coast of Mexico. 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 major damage.

Agatha Strengthens to a Hurricane South of Mexico

Former Tropical Storm Agatha strengthened to a hurricane over the Eastern North Pacific Ocean south of Mexico on Sunday morning. At 8:00 a.m. EDT on Sunday the center of Hurricane Agatha was located at latitude 14.1°N and longitude 99.0°W which put it about 200 miles (320 km) west-southwest of Puerto Angel, Mexico. Agatha was moving toward the north-northwest at 3 m.p.h. (5 km/h). The maximum sustained wind speed was 75 m.p.h. (120 km/h) and and there were wind gusts to 90 m.p.h. (145 km/h). The minimum surface pressure was 987 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.

The center of circulation at the surface of former Tropical Storm Agatha moved under the center of circulation in the middle troposphere early on Sunday. The improved vertical structure allowed Agatha to strengthen to a hurricane. Microwave satellite images indicated that a small eye was forming at the center of Hurricane Agatha. The developing eye was surrounded by a broken ring of thunderstorms and the strongest winds were occurring in that ring. Bands of showers and thunderstorms were in the southern and eastern parts of Agatha’s circulation. Bands in the northwestern part of Hurricane Agatha consisted primarily of showers and lower clouds. Storms near the center of Agatha generated upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 20 miles (30 km) from the center of Agatha. Winds to tropical storm force extended out 80 miles (130 km) from the center of circulation.

Hurricane Agatha will move through an environment favorable for intensification during the next 24 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. Hurricane Agatha will intensify during the next 24 hours. Agatha could undergo a period of rapid intensification once an inner core with an eye and an eyewall develop fully. An upper level trough over Baja California will approach Hurricane Agatha on Monday. 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.

Hurricane 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 few hours. Agatha will move toward the northeast on Sunday night when it moves around the northwestern part of the high pressure system. The upper level trough over Baja California will steer Agatha toward the northeast more quickly on Monday. On its anticipated track, Hurricane Agatha will move approach the coast of Mexico near Puerto Escondido and Puerto Angel during the middle of Monday. There is a chance Agatha could be a major hurricane when it nears the coast of Mexico. 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 seven feet (two meters) along portions of the coast of Oaxaca.

Tropical Low Pressure System Will Drop Heavy Rain on Southern Mexico

A tropical low pressure system designated Potential Tropical Cyclone Seventeen-E by the National Hurricane Center will drop heavy rain on parts of southern Mexico.  At 11:00 p.m. EDT on Tuesday the center of Potential Tropical Cyclone Seventeen-E was located at latitude 13.7°N and longitude 93.4°W which put it about 210 miles (340 km) southeast of Salina Cruz, Mexico.  It was moving toward the west-northwest at 10 m.p.h. (16 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 was1005 mb.

The government of Mexico issued a Tropical Storm Watch for the portion of the coast from Barra de Tonala to Puerto Escondido.

A large low pressure system moved slowly from the western Caribbean Sea into the extreme Eastern North Pacific Ocean west of Guatemala during the past few days.  The low pressure system dropped heavy rain over parts of Nicaragua, Honduras, El Salvador, Guatemala and Belize.  Several smaller centers of circulation developed within the larger low pressure system on Tuesday.  More thunderstorms developed around one of the smaller centers west of Guatemala on Tuesday evening and the sustained wind speed increased to 35 m.p.h. (55 km/h).  Some bands of showers and thunderstorms were beginning to develop around the low pressure system.  A potential primary rainband appeared to be wrapping around the western and southern portions of the center of circulation.

The low pressure system will move through an environment favorable for some intensification on Wednesday.  The low will move over water where the Sea Surface Temperature is near 29.5°C.  An upper level high over the eastern Gulf of Mexico will produce northeasterly winds which will blow toward the top of the low pressure system.  Those winds will cause some vertical wind shear which will inhibit intensification.  The low pressure system will be close to the coast of Mexico, which will also limit intensification.  The low pressure system could intensify while the center is over the warm water.  It is forecast to become a tropical storm on Wednesday, which is why the Tropical Storm Watch was issued.

A high pressure system over the eastern Gulf of Mexico and northwestern Caribbean Sea will steer Potential Tropical Cyclone Seventeen-E toward the northwest during the next several days.  On its anticipated track the low pressure system could make landfall on the coast of Mexico between Barra de Tonala and Puerto Escondido within 24 hours.  It will bring gusty winds to that portion of the coast.  The low pressure system will drop heavy rain on parts of Chiapas and Oaxaca.  It could cause flash floods in some locations.
