Tropical Storm Ivo Forms South of Mexico

Tropical Storm Ivo formed over the Eastern North Pacific Ocean on Wednesday afternoon.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Ivo was located at latitude 14.2°N and longitude 99.1°W which put the center about 195 miles (310 km) south-southeast Acapulco, Mexico.  Ivo was moving toward the west-northwest at 22 m.p.h. (35 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 1008 mb.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened on Wednesday afternoon and the U.S. National Hurricane Center designated the system as Tropical Storm Ivo.

The circulation around Tropical Storm Ivo organized quickly on Wednesday afternoon.  Thunderstorms developed near the center of Ivo’s circulation.  Thunderstorms also formed in bands revolving around the center of Tropical Storm Ivo.  Storms near the center of Ivo began to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Ivo was small.  Winds to tropical storm force extended out 25 miles (40 km) in the northern side of Ivo’s circulation.  The winds in the southern side of Tropical Storm Ivo were blowing at less than tropical storm force.

Tropical Storm Ivo will move through an environment mostly favorable for intensification during the next 24 hours.  Ivo will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the southern side of an upper level ridge over Mexico.  The upper level ridge will produce easterly winds that will blow toward the top of Ivo’s circulation.  However, the winds in the lower atmosphere will also blow from the east.  Since the winds in the upper and lower levels of the atmosphere will blow from the same direction, there will be less vertical wind shear.  Tropical Storm Ivo is likely to strengthen during the next 24 hours.

Tropical Storm Ivo will move around the southern side of a high pressure system that is over Mexico.  The high pressure system will steer Ivo toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Ivo will move parallel to the coast of southern Mexico.

Bands in the northern side of Ivo’s circulation could drop heavy rain on parts of southern Mexico.  Heavy rain could cause flash floods in Guerrero, Michoacan, and Colima.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Henriette continued to churn toward the Central Pacific.  At 5:00 p.m. EDT on Wednesday the center of Tropical Storm Henriette was located at latitude 18.1°N and longitude 131.3°W which put the center about 1555 miles (2505 km) east Hilo, Hawaii.  Henriette was moving toward the west at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 50 m.p.h. (80 km/h) and there were wind gusts to 65 m.p.h. (105 km/h).  The minimum surface pressure was 1005 mb.

Depression Strengthens to Tropical Storm Flossie

Former Tropical Depression Six-E strengthened to Tropical Storm Flossie over the Eastern North Pacific Ocean south of Mexico on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Flossie was located at latitude 13.4°N and longitude 99.9°W which put the center about 240 miles (390 km) south of Acapulco, Mexico.   Flossie was moving toward the west at 9 m.p.h. (15 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 1005 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Zihuatanejo to Cabo Corrientes, Mexico.

Former Tropical Depression Six-E continued to strengthen on Sunday.  The U.S. National Hurricane Center upgraded former Tropical Depression Six-E to Tropical Storm Flossie.

The circulation around Tropical Storm Flossie continue to get more organized on Sunday.  More thunderstorms developed near the center of Flossie’s circulation.  More thunderstorms also formed in bands revolving around the center of Tropical Storm Flossie.  Storms near the center of Flossie generated upper level divergence that pumped mass away from the tropical depression.  The removal of mass caused the surface pressure to decrease.

Tropical Storm Flossie will move through an environment very favorable for intensification during the next 24 hours.  Flossie will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over southeastern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Storm Flossie will intensify during the next 24 hours.  Flossie could intensify rapidly at times.  Tropical Storm Flossie is likely to strengthen to a hurricane on Monday.

Tropical Storm Flossie will move around the southwestern part of a high pressure system over southern Mexico.  The high pressure system will steer the Flossie toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Flossie will move a little closer to the coast of southern Mexico.

Bands in the northern side of Tropical Storm Flossie will bring gusty winds and locally heavy rain to parts of the coast of southern Mexico.  Heavy rains could cause flash floods in some locations.

Tropical Depression Six-E Forms South of Mexico

Tropical Depression Six-E formed over the Eastern North Pacific Ocean south of Mexico early on Sunday.  At 5:00 a.m. EDT on Sunday the center of Tropical Depression Six-E was located at latitude 13.0°N and longitude 99.5°W which put the center about 270 miles (435 km) south of Acapulco, Mexico.  The tropical depression was moving toward the west 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 1008 mb.

A Tropical Storm Watch is in effect for the portion of the coast from Zihuatanejo to Manzanillo, Mexico.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened early on Sunday and the U.S. National Hurricane Center designated the system as Tropical Depression Six-E.

The circulation around Tropical Depression Six-E exhibited much more organization on Sunday morning.  More thunderstorms developed near the center of the depression’s circulation.  More thunderstorms also formed in bands revolving around the center of Tropical Depression Six-E.  Storms near the center of circulation started to generate upper level divergence that pumped mass away from the tropical depression.  The removal of mass caused the surface pressure to start to decrease.

Tropical Depression Six-E will move through an environment very favorable for intensification during the next 24 hours.  The tropical depression will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over southeastern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Tropical Depression Six-E will intensify during the next 24 hours.  It is likely to strengthen to a tropical storm by Monday.  The tropical depression could intensify to a hurricane early next week.

Tropical Depression Six-E will move around the southwestern part of a high pressure system over southern Mexico.  The high pressure system will steer the tropical depression toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Depression Six-E will move a little closer to the coast of southern Mexico.

Bands on the northern side of Tropical Depression Six-E will bring gusty winds and locally heavy rain to parts of the coast of southern Mexico.  Heavy rains could cause flash floods in some locations.

Hurricane Erick Hits Southern Mexico

Hurricane Erick hit the coast of southern Mexico on Thursday morning.  Erick started to weaken after it moved inland near the border between Oaxaca and Guerrero.  At 2:00 p.m. EDT on Thursday the center of Hurricane Erick was located at latitude 17.1°N and longitude 99.0°W which put the center about 60 miles (95 km) east-northeast of Acapulco, Mexico.  Erick was moving toward the northwest at 12 m.p.h. (19 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 988 mb.

A Hurricane Warning is in effect for the portion of the coast from Puerto Escondido to Acapulco, Mexico.

A Tropical Storm Warning was in effect for the portion of the coast from Acapulco to Tecpan de Galeana, Mexico.

Hurricane Erick rapidly intensified to a Category 4 hurricane on the Saffir-Simpson Scale before it made landfall on the coast of Mexico.  The maximum sustained wind speed at the time of landfall was 140 m.p.h. (225 km/h).

Hurricane force winds extended out 15 miles (25 km) from the center of Erick’s circulation at the time of landfall.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Hurricane Erick.

The Hurricane Intensity Index (HII) for Hurricane Erick at the time of landfall was 28.2.  The Hurricane Size Index (HSI) was 8.1 and the Hurricane Wind Intensity Size Index (HWISI) was 36.3.  Hurricane Erick was similar in size and intensity to Hurricane Charley when Charley hit southwest Florida in 2004.

The center of Hurricane Erick made landfall near Punta Maldonado.  Erick will continue to move northwest over Guerrero.  Hurricane Erick will weaken quickly when it moves over the Sierra Madres del Sur.  Erick will continue to drop heavy rain over parts of Oaxaca and Guerrero as it weakens.  Heavy rain could cause flash floods in some locations.

Hurricane Erick Rapidly Intensifies to Cat. 2

Hurricane Erick rapidly intensified to a Category 2 hurricane on the Saffir-Simpson Scale as it moved over the Eastern North Pacific Ocean south of Mexico on Wednesday.  At 2:00 p.m. EDT on Wednesday the center of Hurricane Erick was located at latitude 14.2°N and longitude 96.3°W which put the center about 215 miles (345 km) southeast of Punta Maldonado, Mexico.    Erick was moving toward the northwest at 9 m.p.h. (15 km/h).   The maximum sustained wind speed was 100 m.p.h. (160 km/h) and there were wind gusts to 120 m.p.h. (195 km/h).   The minimum surface pressure was 971 mb.

A U.S. Air Force Reserve Hurricane Hunter reconnaissance plane investigating Hurricane Erick on Wednesday afternoon found that Erick had rapidly intensified to Category 2 on the Saffir-Simpson Scale.  A circular eye with a diameter of 15 miles (24 km) was present at the center of Erick’s circulation.  The eye was surrounded by a 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 Erick.  Storms near the core generated strong upper level divergence that pumped mass away in all directions from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The distribution of winds speeds around Hurricane Erick was fairly symmetrical.  Winds to hurricane force extended out 15 miles (25 km) from the center of Erick’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Erick.

Hurricane Erick will move through an environment very favorable for intensification during the next 18 hours.  Erick will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge over southern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  Hurricane Erick will intensify during the next 18 hours. Erick is likely to intensify rapidly.  Hurricane Erick is likely to strengthen to a major hurricane by Thursday.

Hurricane Erick will move around the southwestern part of a high pressure system over Central America and southern Mexico.  The high pressure system will steer Erick toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Erick will move toward the coast of southern Mexico.  Erick is likely to make landfall in southern Mexico between Acapulco and Punta Maldonado early on Thursday.

Hurricane Erick is likely to be a major hurricane when it makes landfall on the coast of Mexico.  Erick will bring strong winds and heavy rain to parts of Oaxaca, Guerrero and Michoacan.  The strongest winds and heaviest rains will occur in Guerrero.  Heavy rain will cause flash floods in some locations.  Hurricane Erick could also cause a storm surge of up to 10 feet (3 meters) along the coast.

Tropical Depression Likely to Form South of Mexico

A tropical depression is likely to form over the Eastern North Pacific Ocean south of Mexico during the next several days.  A broad area of low pressure was located south of Mexico.  At 8:00 a.m. EDT on Monday the center of the area of low pressure was near latitude 10.0°N and longitude 98.0°W which put the center about 500 miles (805 km) south of Acapulco, Mexico.  The low pressure system was moving toward the northwest 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 1008 mb.

A broad area of low pressure was located over the Eastern North Pacific Ocean south of Mexico.  Thunderstorms were scattered inside the broad circulation of the low pressure system.  Satellite images appeared to indicate that some of the thunderstorms were beginning to organize into bands.

The broad area of low pressure will move through an environment favorable for the formation of a tropical depression during the next 48 hours.  The area of low pressure will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle of an upper level ridge that is south of Mexico.  The upper level winds are weak near the middle of the ridge and there will be little vertical wind shear.  The broad area of low pressure is likely to develop into a tropical depression during the next 48 hours.

The broad area of low pressure will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer the area of low pressure toward the northwest during the next 48 hours.  On its anticipated track, the area of low pressure will move parallel to the coast of Mexico.

Tropical Depression Fourteen-E Forms Southwest of Mexico

Tropical Depression Fourteen-E formed over the Eastern North Pacific Ocean southwest of Mexico on Wednesday morning.  At 10:00 a.m. EST on Wednesday the center of Tropical Depression Fourteen-E was located at latitude 23.1°N and longitude 106.1°W which put the center about 490 miles (790 km) west-southwest of Acapulco, Mexico.  The tropical depression was moving toward the northeast at 3 m.p.h. (5 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 1006 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Mexico strengthened on Wednesday morning and the U.S. National Hurricane Center designated the system as Tropical Depression Fourteen-E.  More thunderstorms formed near the center of the tropical depression.  More thunderstorms also developed in bands revolving around the center of the depression’s circulation.  Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Fourteen-E will move through an environment somewhat favorable for intensification during the next 24 hours.  The tropical depression will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the eastern side of an upper level trough west of Baja California.  The upper level trough will produce southwesterly winds that will blow toward the top of the depression’s circulation.  Those winds will cause moderate vertical wind shear.  The wind shear will inhibit intensification, but the shear may not be enough to prevent some intensification.  Tropical Depression Fourteen-E could intensify to a tropical storm during the next 24 hours.

Tropical Depression Fourteen-E will move around the southern side of a high pressure system over the Eastern North Pacific Ocean west of Mexico.  The high pressure system will strengthen during the next 24 hours.  When the high pressure system strengthens it will push the tropical depression toward the southeast.  On its anticipated track, Tropical Depression Fourteen-E will remain west of Mexico during the next several days.
