Tropical Storm Dalila Weakens

Tropical Storm Dalila weakened as it moved away from Mexico on Sunday.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Dalila was located at latitude 18.2°N and longitude 107.9°W which put the center about 235 miles (380 km) west-southwest of Manzanillo, Mexico.  Dalila was moving toward the west-northwest at 9 m.p.h. (15 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 999 mb.

Tropical Storm Dalila weakened on Sunday when it moved over cooler water south of Baja California.  Many of the thunderstorms in Dalila’s circulation weakened when the tropical storm move over cooler water.  Thunderstorms were still occurring in bands in the western part of Tropical Storm Dalila.  Bands in the other parts of Dalila’s circulation consisted primarily of showers and lower clouds.  The thunderstorms remaining in Tropical Storm Dalila generated less upper level divergence.  More mass was converging in the lower levels of the atmosphere  which caused the surface pressure to increase.

The size of the circulation around Tropical Storm Dalila decreased as Dalila weakened.  Winds to tropical storm force extended out 90 miles (145 km) from the center of Dalila’s circulation.

Tropical Storm Dalila will move through an environment unfavorable for intensification during the next 24 hours.  Dalila will move over water where where the Sea Surface Temperatures are near 24°C.  It will move under the southern part of an upper level ridge over southern Mexico and the adjacent part of the Eastern North Pacific Ocean.  The upper level ridge will produce east-northeasterly winds that will blow toward the top of Dalila’s circulation.  Those winds will cause the vertical wind shear to increase.  Cooler Sea Surface Temperatures and more vertical wind shear will cause Tropical Storm Dalila to continue to weaken during the next 24 hours.

Tropical Storm Dalila will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer Dalila toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Dalila will continue to move farther away from the coast of southwestern Mexico.

Disturbance Prompts Tropical Storm Watch for Mexico

The potential risk caused by a tropical disturbance over the Eastern North Pacific Ocean prompted the government of Mexico to issued a Tropical Storm Watch for a portion of the coast on Thursday afternoon.  The U.S. National Hurricane Center designated the tropical disturbance as Potential Tropical Cyclone Four-E.  At 5:00 p.m. EDT on Thursday the center of Potential Tropical Cyclone Four-E was located at latitude 11.3°N and longitude 100.2°W which put the center about 450 miles (725 km) south-southeast of Zihuatanejo, Mexico.  The tropical disturbance was moving toward the west-northwest at 7 m.p.h. (11 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 Tropical Storm Watch was in effect for the portion of the coast from Tecpan de Galeana to Manzanillo, Mexico.

A tropical disturbance over the Eastern North Pacific Ocean exhibited more organization on Thursday afternoon.  Satellite loops appeared to show a counterclockwise rotation in the middle troposphere.  It was unclear if there was a well defined center of circulation at the surface.  Thunderstorms were occurring in bands in the northern and in the southern periphery of the tropical disturbance.  There were few thunderstorms near the broad center in the middle troposphere.

The U.S. National Hurricane Center designated the tropical disturbance as Potential Tropical Cyclone Four-E and began to issue regular advisories on the system.

Potential Tropical Cyclone Four-E will move through an environment favorable for the formation of a tropical cyclone during the next 24 hour.  The tropical disturbance will move over water where where the Sea Surface Temperatures are near 30°C.  It will move under the middle part 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.  Potential Tropical Cyclone Four-E is likely to form into a tropical storm during the next 24 hours.

Potential Tropical Cyclone Four-E will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer the tropical disturbance toward the northwest during the next 24 hours.  On its anticipated track, Potential Tropical Cyclone Four-E will move closer to the coast of southwestern Mexico.

Thunderstorms in bands in the northern periphery of Potential Tropical Cyclone Four-E will bring gusty winds and locally heavy rain to coastal portions of southwestern Mexico.  The heaviest rain is likely fall in parts of Guerrero, Michoacan, and Colima.  Heavy rain could cause flash floods in some location.

Barbara Intensifies to Hurricane Southwest of Mexico

Former Tropical Storm Barbara intensified to a hurricane over the Eastern North Pacific Ocean southwest of Mexico on Monday morning.  At 11:00 a.m. EDT on Monday the center of Hurricane Barbara was located at latitude 17.6°N and longitude 106.1°W which put the center about 155 miles (245 km) southwest of Manzanillo, Mexico.  Barbara was moving toward the 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 991 mb.

Former Tropical Storm Barbara intensified to a hurricane over the Eastern North Pacific Ocean southwest of Mexico on Monday morning.  The inner end of a rainband wrapped around the southern and eastern side of the center of Barbara’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Hurricane Barbara.  Storms near the center of Barbara generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The circulation around Hurricane Barbara was small.  Winds to hurricane force extended out 15 miles (25 km) from the center of Barbara’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Hurricane Barbara.

Hurricane Barbara will move through an environment favorable for intensification during the next 12 hours.  Barbara will move over water where where the Sea Surface Temperatures are near 27°C.  It will move under the middle part of an upper level ridge over Mexico and 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 Barbara could continue to intensify during the next 12 hours.  Barbara will move over cooler water by Tuesday which will cause it to start to weaken.

Hurricane Barbara will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer Barbara toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Barbara will move closer to the southern end of Baja California.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Cosme was also intensifying.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Cosme was located at latitude 14.5°N and longitude 113.3°W which put the center about 620 miles (1000 km) south-southwest of the southern tip of Baja California.  Cosme was moving toward the west-northwest at 6 m.p.h. (10 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 994 mb.

Tropical Storm Alvin Intensifies Southwest of Mexico

Tropical Storm Alvin intensified over the Eastern North Pacific Ocean southwest of Mexico on Thursday.  At 11:00 p.m. EDT on Thursday the center of Tropical Storm Alvin was located at latitude 16.0°N and longitude 107.9°W which put the center about 305 miles (495 km) west-southwest of Manzanillo, Mexico.  Alvin was moving toward the northwest at 12 m.p.h. (19 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 999 mb.

Tropical Storm Alvin intensified over the Eastern North Pacific Ocean southwest of Mexico on Thursday.  The inner end of a rainband wrapped around the western side of the center of Alvin’s circulation.  Other bands of showers and thunderstorms were revolving around the center of Tropical Storm Alvin.  Storms near the center of Alvin generated upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

The area of tropical storm force winds increased in size when Tropical Storm Alvin intensified on Thursday.  Winds to tropical storm force extended out 140 miles (225 km) from the center of Alvin’s circulation.

Tropical Storm Alvin will move into an environment that will become unfavorable for intensification during the next 24 hours.  Alvin will move over water where where the Sea Surface Temperatures are near 26°C.  It will move under the southeastern part of an upper level low over Baja California.  The upper level low will produce southwesterly winds that will blow toward the top of Alvin’s circulation.  Those winds will cause the vertical wind shear to increase on Friday.  The combination of cooler Sea Surface Temperatures and more vertical wind shear will cause Tropical Storm Alvin to start to weaken during the next 24 hours.

Tropical Storm Alvin will move around the southwestern part of a high pressure system over Mexico.  The high pressure system over Mexico and the upper level low over Baja California will steer Alvin toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Alvin will move parallel to the west coast of Mexico.

Depression Strengthens to Tropical Storm Alvin

Former Tropical Depression One-E strengthened to Tropical Storm Alvin over the Eastern North Pacific Ocean south of Mexico on Thursday morning.  At 11:00 a.m. EDT on Thursday the center of Tropical Storm Alvin was located at latitude 13.8°N and longitude 106.3°W which put the center about 345 miles (555 km) south-southwest of Manzanillo, Mexico.  Alvin was moving toward the northwest at 10 m.p.h. (16 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.

Former Tropical Depression One-E strengthened on Thursday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Alvin.  Numerous thunderstorms formed near the center of Alvin’s circulation.  More thunderstorms also developed in bands revolving around the center of Tropical Storm Alvin.  Storms near the center of Alvin generated more upper level divergence that pumped mass away from the tropical storm.  The removal of mass caused the surface pressure to decrease.

Winds to tropical storm force extended out 45 miles (75 km) from the center of Tropical Storm Alvin.

Tropical Storm Alvin will move through an environment favorable for intensification during the next 24 hours.  Alvin will move over water where where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge that is south of Mexico.  The upper level ridge will produce southerly winds that will blow toward the top of Alvin’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Alvin will intensify during the next 24 hours.

Tropical Storm Alvin will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer Alvin toward the north-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Alvin will move parallel to the west coast of Mexico.

Tropical Depression One-E Forms South of Mexico

Tropical Depression One-E formed over the Eastern North Pacific Ocean south of Mexico on Wednesday afternoon.  At 5:00 p.m. EDT on Wednesday the center of the area of Tropical Depression One-E was located at latitude 11.9°N and longitude 109.7°W which put the center about 465 miles (745 km) south of Manzanillo, Mexico.  Tropical Depression One-E was moving toward the northwest at 9 m.p.h. (15 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 south of Mexico strengthened on Wednesday and the U.S. National Hurricane Center designated the system as Tropical Depression One-E.  A distinct low level center of circulation developed in the middle of a larger low pressure system south of Mexico.  More thunderstorms formed near the center of circulation.  Bands of thunderstorms also developed.  Those bands of storms began to revolve around the center of Tropical Depression One-E.  Storms near the center of circulation started to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression One-E will move through an environment favorable for intensification during the next 24 hours. The tropical depression will move over water where where the Sea Surface Temperatures are near 29°C. It will move under the western part of an upper level ridge that is south of Mexico.  The upper level ridge will produce southerly winds that will blow toward the top of the tropical depression.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Depression One will intensify to a tropical storm during the next 24 hours.

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

Tropical Storm John Makes Landfall in Mexico Again

Tropical Storm John made landfall on the west coast of Mexico again on Friday.  At 2:00 p.m. EDT on Friday the center of Tropical Storm John was located at latitude 18.3°N and longitude 103.2°W which put the center about 90 miles (145 km) southeast of Manzanillo, Mexico.  John was moving toward the northwest at 3 m.p.h. (5 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 996 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Punta Maldonado to Manzanillo, Mexico.

The center of Tropical Storm John moved back over the west coast of Mexico between Lazaro Cardenas and Manzanillo on Friday afternoon.  The maximum sustained wind speed in Tropical Storm John at the time of landfall was 60 m.p.h. (95 km/h).

The strongest winds were occurring in the southeastern portion of Tropical Storm John.  Winds to tropical storm force extended out 160 miles (260 km) in the southeastern quadrant of Tropical Storm John.  Winds to tropical storm force only extended out 70 miles (110 km) in the other parts of John’s circulation.

Tropical Storm John will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer John slowly toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm John will continue to grind slowly along the west coast of Mexico.

Tropical Storm John will drop heavy rain over parts of Colima, Jalisco, and Michoacan.  Heavy rain is likely to cause flash floods in some locations.

John Strengthens Back to a Hurricane Near West Coast of Mexico

Former Tropical Storm John strengthened back to a hurricane over the Eastern North Pacific Ocean near the west coast of Mexico on Thursday morning.  At 8:00 a.m. EDT on Thursday the center of Hurricane John was located at latitude 17.3°N and longitude 102.6°W which put the center about 55 miles (90 km) south-southwest of Lazaro Cardenas, Mexico.  John was moving toward the west-northwest at 4 m.p.h. (6 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 979 mb.

A Hurricane Warning is in effect for the portion of the coast from Tecpan de Galeana to Punta San Telmo, Mexico.

A Tropical Storm Warning is in effect for the portion of the coast from Punta Maldonado to Tecpan de Galeana, Mexico.  The Tropical Storm Storm Warning includes Acapulco.  A Tropical Storm Warning is also in effect for the portion of the coast from Punta San Telmo to Manzanillo, Mexico.

Former Tropical Storm John strengthened back to a hurricane on Thursday morning as the center moved over the Eastern North Pacific Ocean just off the west coast of Mexico.  A small circular eye formed at the center of Hurricane John.  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 revolved around the core of John’s circulation.  Storms near the core of John generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane John was small.  Winds to hurricane force extended out 15 miles (25 km) from the center of John’s circulation.  Winds to tropical storm force extended out 140 miles (225 km) in the southeastern quadrant of Hurricane John.  Winds to tropical storm force only extended out 70 miles (110 km) in the other parts of John’s circulation.

Hurricane John will move through an environment favorable for intensification during the next 18 hours.  John will move over water where the Sea Surface Temperatures are near 30°C.  It will be in a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane John will intensify during the next 18 hours as long as the eye stays over water.

Hurricane John will move around the southwestern part of a high pressure system over Mexico.  The high pressure system will steer John slowly toward the north-northwest during the next 24 hours. On its anticipated track, Hurricane John will make another landfall on the west coast of Mexico on Thursday night.

Hurricane John will bring strong winds and locally heavy rain to the west coast of Mexico.  The strongest winds and heaviest rain will occur in Guerrero and Colima.  Heavy rain is likely to cause flash floods and mudslides.  Hurricane John could also cause a storm surge of up to 8 feet (2.4 meters along the coast.

Tropical Storms Emilia and Fabio Interact

The circulations around Tropical Storms Emilia and Fabio were interacting on Tuesday afternoon.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Emilia was located at latitude 14.4°N and longitude 115.3°W which put the center about 685 miles (1110 km) south-southwest of the southern tip of Baja California.  Emilia was moving toward the northwest at 3 m.p.h. (5 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 992 mb.

At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Fabio was located at latitude 19.2°N and longitude 113.9°W which put the center about 625 miles (1010 km) west of Manzanillo, Mexico.  Fabio was moving toward the west-northwest at 21 m.p.h. (33 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 997 mb.

The circulations around Tropical Storm Emilia and Fabio were interacting on Tuesday afternoon.  Winds blowing around the southern side of Fabio’s circulation were interacting with winds that were blowing around the northern side of Tropical Storm Emilia.  The interactions were occurring in both the upper and lower troposphere.  The interactions were affecting the structures of both tropical storms.

Tropical Storm Emilia appeared to be the larger and more powerful of the two tropical storms.  Even so, the flow around the southern side of Fabio was having an effect on Emilia’s structure.  Most of the thunderstorms in Tropical Storm Emilia were occurring in bands in the southern half of Emilia’s circulation.  Bands in the northern side of Emilia consisted primarily of showers and low clouds.  Outflow from Tropical Storm Fabio was inhibiting upper level divergence to the north of Tropical Storm Emilia.

The interactions between the two tropical storms was also affecting the distribution of wind speeds in Tropical Storm Emilia.  Winds to tropical storm force extended out 140 miles (220 km) in the southern half of Emilia’s circulation.  Winds to tropical storm force only extended out 70 miles (110 km) in the northern side of Emilia.

The interaction with Tropical Storm Emilia appeared to be contributing to the start of a weakening trend in Tropical Storm Fabio.  The interaction with Emilia was also affecting the structure of Tropical Storm Fabio.  Most of the thunderstorms were occurring in bands in the eastern side of Fabio’s circulation.  Bands in the western part of Tropical Storm Fabio consisted primarily of showers and lower clouds.  Outflow from Tropical Storm Emilia was inhibiting upper level divergence to the south and west of Tropical Storm Fabio,

The interactions between the two tropical storms was also affecting the distribution of wind speeds in Tropical Storm Fabio.  Winds to tropical storm force extended out 100 miles (160 km) in the eastern side of Fabio’s circulation.  Winds to tropical storm force only extended out 35 miles (55 km) in the eastern half of Fabio.

It is possible that the larger circulation around Tropical Storm Emilia could absorb the smaller circulation of Tropical Storm Fabio.  The circulation around Fabio will continue to disrupt part of the circulation in the northern part of Tropical Storm Emilia.  Emilia may not intensify much during the interactions between the two storms.

Tropical Storm Emilia will move through an environment that is otherwise favorable for intensification during the next 24 hours.  Emilia will move move over water where the Sea Surface Temperatures are near 28°C.   It will move under an axis of an upper level ridge over the Eastern North Pacific Ocean.  The upper level winds are weak near the axis of the ridge.  There will be little vertical wind shear except for the shear caused by the outflow from Tropical Storm Fabio.  Tropical Storm Emilia is likely to intensify during the next 24 hours.  Emilia could strengthen to a hurricane.

Tropical Storm Emilia will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The interaction with Tropical Storm Fabio is likely to pull Emilia toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Emilia will move farther away from Baja California.  Emilia is likely to be steered toward the west-northwest by the high pressure system after it absorbs Tropical Storm Fabio.

Tropical Storm Fabio Forms Southwest of Mexico

Tropical Storm Fabio formed over the Eastern North Pacific Ocean southwest of Mexico on Monday morning.  At 11:00 a.m. EDT on Monday the center of Tropical Storm Fabio was located at latitude 14.8°N and longitude 106.9°W which put the center about 335 miles (540 km) southwest of Manzanillo, Mexico.  Fabio was moving toward the 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 Eastern North Pacific Ocean southwest of Mexico strengthened on Monday morning and the U.S. National Hurricane Center designated the system as Tropical Storm Fabio.  More thunderstorms formed near the center of Fabio’s circulation.  However, the distribution of thunderstorms around Tropical Storm Fabio was asymmetrical.  Thunderstorms were occurring in bands in the southern and western parts of Fabio’s circulation.  Bands in the northern and eastern parts of Tropical Storm Fabio consisted primarily of showers and lower clouds.  Storms near the center of Fabio generated upper level divergence that pumped mass away to the west of the tropical storm.

Winds to tropical storm force extended out 70 miles in the southeastern quadrant of Tropical Storm Fabio.  The winds in the other parts of Fabio’s circulation were blowing at less than tropical storm force.

Tropical Storm Fabio will move through an environment somewhat favorable for intensification during the next 24 hours.  Fabio will move over water where the Sea Surface Temperatures are near 28°C.   It will move under the southern part of an upper level ridge over the Eastern North Pacific Ocean.  The ridge will produce easterly winds that will blow toward the top of Fabio’s circulation.  Those winds will cause some vertical wind shear, but the shear may not be enough to prevent intensification. The circulation around Fabio could interact with the circulation around Tropical Storm Emilia.  Tropical Storm Fabio could intensify during the next 24 hours.

Tropical Storm Fabio is currently being steered by the circulation around Tropical Storm Emilia.  Fabio is forecast to be steered toward the northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fabio will move farther away from Mexico.  There is a chance that the circulations around Fabio and Tropical Storm Emilia could merge into a single circulation.

Elsewhere, Tropical Storms Carlotta, Daniel and Emilia were spinning over the Eastern North Pacific Ocean.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Carlotta was located at latitude 20.4°N and longitude 127.2°W which put the center about 1125 miles (1805 km) west of the southern tip of Baja California.  Carlotta was moving toward the west at 9 m.p.h. (15 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 1001 mb.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Daniel was located at latitude 15.6°N and longitude 127.7°W which put the center about 1265 miles (2035 km) west-southwest of the southern tip of Baja California.  Daniel was moving toward the northeast at 14 m.p.h. (22 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.

At 11:00 a.m. EDT on Monday the center of Tropical Storm Emilia was located at latitude 14.5°N and longitude 114.1°W which put the center about 640 miles (1035 km) west-southwest of the southern tip of Baja California.  Emilia was moving toward the south-southwest at 5 m.p.h. (8 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. (120 km/h).  The minimum surface pressure was 1001 mb.
