Celia Strengthens Back to a Tropical Storm

One time Tropical Storm Celia strengthened back to a tropical storm over the Eastern North Pacific Ocean south of Mexico on Tuesday morning. At 11:00 a.m. EDT on Tuesday the center of Tropical Storm Celia was located at latitude 11.6°N and longitude 99.5°W which put it about 365 miles (590 km) south of Acapulco, Mexico. Celia was moving toward the west at 12 m.p.h. (19 km/h). The maximum sustained wind speed was 40 m.p.h. (65 km/h) and and there were wind gusts to 50 m.p.h. (80 km/h). The minimum surface pressure was 1005 mb.

After passing south of Guatemala during the weekend as a weak tropical depression, former Tropical Storm Celia strengthened back to a tropical storm on Tuesday morning. Winds to tropical storm force extended out 60 miles in the northern half of Tropical Storm Celia. Winds in the southern half of Celia were blowing at less than tropical storm force. The circulation around Tropical Storm Celia continued to be poorly organized. The strongest thunderstorms were occurring in bands located west of the center of Celia’s circulation. Bands in the eastern half of the circulation consisted primarily of showers and lower clouds. An upper level ridge over southern Mexico was producing moderate easterly winds that were blowing across the top of Celia’s circulation. Those winds cause moderate vertical wind shear and the wind shear was causing the asymmetrical distribution of thunderstorms.

Tropical Storm Celia will move through an environment that will be only marginally favorable for intensification during the next 24 hours. Celia will move over water where the Sea Surface Temperatures are near 29˚C. However, the upper level ridge over southern Mexico will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification during the next day or so. Tropical Storm Celia will move into an area where the upper level winds are weaker later this week. That will cause the vertical wind shear to diminish. Tropical Storm Celia is likely to intensify when the shear diminishes. Celia could strengthen to a hurricane by the end of the week.

Tropical Storm Celia will move south of a high pressure system over Mexico during the next 48 hours. The high pressure system will steer Celia toward the west-northwest. On its anticipated track Tropical Storm Celia will move parallel to the coast of southwest Mexico.

Hurricane Rick Moves Toward Mexico

Hurricane Rick moved slowly toward the west coast of Mexico on Sunday afternoon. At 2:00 p.m. EDT on Sunday the center of Hurricane Rick was located at latitude 16.4°N and longitude 101.7°W which put it about 85 miles (135 km) south of Zihuatenajo, Mexico. Rick was moving toward the north at 6 m.p.h. (10 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.

A Hurricane Warning was in effect for the portion of the coast from Tecpan De Galeana to Punta San Telmo, Mexico. Tropical Storm Warnings were in effect for the portions of the coast from Punta San Telmo to Manzanillo and from Tecpan de Galeana to Acapulco, Mexico.

The intensity of Hurricane Rick was steady during the past few hours. The inner core of Rick’s circulation was not as well organized as it was on Saturday afternoon. There were breaks in the ring of thunderstorms surrounding the center of Hurricane Rick. Storms near the center of circulation continued to generate upper level divergence that pumped mass away from the hurricane. Bands of showers and thunderstorms revolved around the center of Rick. The circulation around Hurricane Rick was small. Winds to hurricane force extended out 15 miles (25 km) from the center of Rick. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Hurricane Rick will move through an environment favorable for intensification during the next 12 hours. Rick will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Rick could intensify during the next 12 hours. However, the less organized core of Rick will limit intensification. An upper level trough near the west coast of the U.S. will produce strong southwesterly winds that will blow toward the top of Rick’s circulation on Monday. Those winds will cause vertical wind shear and the shear could cause Hurricane Rick to weaken as it nears the coast of Mexico.

Hurricane Rick will move around the western part of a high pressure system over Mexico during the next 24 hours. A large upper level trough near the west coast of the U.S. will cause the high pressure system to weaken. As the high pressure system weakens, the southern part of the upper level trough will steer Rick toward the north. On its anticipated track Hurricane Rick could make landfall on the west coast of Mexico on Sunday night. Hurricane Rick will bring strong winds and locally heavy rain to the portion of the coast near Zihuatanejo. Heavy rain could cause flash floods in parts of Guerrero and Michoacan on Sunday night and Monday.

Rick Rapidly Intensifies to a Hurricane South of Mexico

Former Tropical Storm Rick rapidly intensified to a hurricane south of Mexico early on Saturday. At 8:00 a.m. EDT on Saturday the center of Hurricane Rick was located at latitude 14.3°N and longitude 101.5°W which put it about 235 miles (380 km) south of Zihuatenajo, Mexico. Rick was moving toward the north-northwest at 6 m.p.h. (10 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 990 mb.

A Hurricane Watch was in effect for the portion of the coast from Tecpan De Galeana to Punta San Telmo, Mexico. Tropical Storm Watches were in effect for the portions of the coast from Punta San Telmo to Manzanillo and from Tecpan de Galeana to Acapulco, Mexico.

Former Tropical Storm Rick intensified rapidly during Friday night and it strengthened to a hurricane early on Saturday. A small eye formed at the center of Hurricane Rick. 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 Rick’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane. The removal of mass allowed the surface pressure to decrease quickly. The circulation around Hurricane Rick was small. Winds to hurricane force extended out 15 miles (25 km) from the center of Rick. Winds to tropical storm force extended out 60 miles (95 km) from the center of circulation.

Hurricane Rick will move through an environment very favorable for intensification during the next 24 hours. Rick will move over water where the Sea Surface Temperatures are near 30˚C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Rick will likely continue to intensify rapidly during the next 24 hours. Rick could strengthen to a major hurricane on Sunday.

Hurricane Rick will move around the western part of a high pressure system over Mexico during the next 24 hours. A large upper level trough approaching the west coast of the U.S. will cause the high pressure system to weaken during the weekend. As the high pressure system weakens, the southern part of the upper level trough will steer Rick toward the north. On its anticipated track Hurricane Rick could approach the west coast of Mexico by later on Sunday. Rick could be a major hurricane when it approaches the coast of Mexico. The Hurricane and Tropical Storm Watches are likely to be changed to warnings later today. Hurricane Rick could bring strong winds and heavy rain to Guerrero and Michoacan on Sunday night and Monday.

Tropical Storm Nora Forms South of Acapulco

Tropical Storm Nora formed south of Acapulco, Mexico on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Tropical Storm Nora was located at latitude 12.5°N and longitude 100.8°W which put it about 310 miles (500 km) south of Acapulco, Mexico. Nora was moving toward the west-northwest at 7 m.p.h. (11 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 1003 mb.

A Hurricane Watch was issued for the portion of the coast from Lazaro Cardenas to Cabo Corrientes, Mexico. A Tropical Storm Watch was issued for the portion of the coast from Lazaro Cardenas to Tecpan de Galeana, Mexico.

An area of low pressure south of Acapulco, Mexico exhibited more organization on Thursday morning and the National Hurricane Center designated the system as Tropical Storm Nora. The distribution of thunderstorms around Tropical Storm Nora was asymmetrical. The strongest thunderstorms were occurring in bands in the southern half of Nora. Bands in the north half of the tropical storm consisted primarily of showers and lower clouds. Storms near the center of Nora began to generate upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 45 miles (75 km) from the center of circulation.

Tropical Storm will move through an environment somewhat favorable for intensification during the next 36 hours. Nora 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 centered near Baja California. The ridge will produce northeasterly winds that will blow toward the top of Nora’s circulation. Those winds are already causing the asymmetrical distribution of thunderstorms and they will cause vertical wind shear. The wind shear will inhibit intensification, but it may not be strong enough to keep Tropical Storm Nora from intensifying during the next 36 hours.

Tropical Storm Nora will move around the western end of a high pressure system over Mexico. The high pressure system will steer Nora toward the northwest during the next 36 hours. On its anticipated track Tropical Storm Nora could approach the west coast of Mexico on Friday night. Nora could be a strong tropical storm or a hurricane when it approaches the coast.

Tropical Storm Linda Forms South of Mexico

Tropical Storm Linda formed south of Mexico on Tuesday. At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Linda was located at latitude 14.4°N and longitude 102.8°W which put it about 260 miles (480 km) southwest of Acapulco, Mexico. Linda was moving toward the west-northwest at 10 m.p.h. (16 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 1003 mb.

The circulation around a low pressure system south of Mexico strengthened on Tuesday afternoon and the National Hurricane Center designated the system as Tropical Storm Linda. The inner end of a rainband was wrapping around the western and southern sides of the center of Linda. Other bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical storm. Winds to tropical storm force extended out 90 miles (145 km) on the eastern side of Linda. Winds to tropical storm force extended out 60 miles in the western half of the circulation.

Tropical Storm Linda will move through an environment relatively favorable for intensification during the next 48 hours. Linda 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 centered over Mexico. The ridge will produce northeasterly winds that will blow toward the top of Tropical Storm Linda’s circulation. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification but it may not strong enough to prevent Linda from strengthening.

Tropical Storm Linda will move south of a high pressure system that extends from Mexico westward over the Eastern North Pacific Ocean. The high pressure system will steer Linda toward the west-northwest during the next several days. On it anticipated track Tropical Storm Linda will move away from Mexico.

Elsewhere over the Eastern North Pacific Ocean, Tropical Storm Kevin was spinning south of Baja California. At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Kevin was located at latitude 19.1°N and longitude 115.5°W which put it about 445 miles (720 km) southwest of the southern tip of Baja California. Kevin was moving toward the west-northwest at 10 m.p.h. (16 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 1000 mb.

Tropical Development Possible Southwest of Mexico

Development of a tropical cyclone southwest of Mexico is possible during the next few days. At 2:00 p.m. EDT on Friday the center of Invest 90E was located at latitude 11.2°N and longitude 102.5°W which put it about 415 miles (670 km) south-southwest of Acapulco, Mexico. The Invest was moving toward the west 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 1008 mb.

An area of low pressure, currently designated as Invest 90E, exhibited more organization on Friday afternoon. The National Hurricane Center (NHC) issued a Special Tropical Weather Outlook for the low pressure system. NHC indicated that there was a 40% probability that the system would develop into a tropical depression or a tropical storm during the next 48 hours and a 60% chance that development would occur during the next five days.

More thunderstorms developed near the center of Invest 90E. Bands of showers and thunderstorms also developed and the bands began to revolve around the center of the low pressure system. Storms near the center began to generate upper level divergence that pumped mass away from the system.

Invest 90E will move through an environment favorable for develop of a tropical cyclone during the next 36 hours. It will move over water where the Sea Surface Temperatures will be near 29°C. The low pressure system will move under the center of an upper level ridge southwest of Mexico. The winds are weak near the center of the ridge and there will be little vertical wind shear. Invest 90E is likely to develop into a tropical depression and it could quickly intensify into a tropical storm.

Invest 90E will move southeast of a large high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer the Invest slowly toward the west-northwest. On its anticipated track the low pressure system will remain southwest of Mexico during the weekend.

Tropical Storm Cristina Forms South of Acapulco

Tropical Storm Cristina formed south of Acapulco on Monday.  At 11:00 p.m. EDT on Monday the center of Tropical Storm Cristina was located at latitude 11.2°N and longitude 101.3°W which put it about 405 miles (650 km) south-southwest of Acapulco, Mexico.  Cristina was moving toward the west-northwest at 15 m.p.h. (24 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 distinct low pressure center organized quickly in a tropical wave south of Mexico on Monday.  Satellite images showed a well developed counterclockwise rotation around the center of circulation.  Bands of showers and thunderstorms were revolving around the center of Tropical Storm Cristina.  The inner end of a rainband wrapped around the southern and eastern sides of the center of circulation.  Storms near the center of circulation were generating upper level divergence which was pumping mass away in all directions from the tropical storm,  Winds to tropical storm force extended out about 35 miles (55 km) from the center of Cristina.

Tropical Storms Cristina will move through an environment favorable for intensification during the next several days.  Cristina will move over water where the Sea Surface Temperature is near 29.5°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Storm Cristina will continue to strengthen and it could intensify rapidly.  Cristina will intensify into a hurricane within 36 hours and it could strengthen into a major hurricane later this week.

Tropical Storm Cristina will move around the southwestern part of a ridge of high pressure over Mexico and the southwestern U.S.  The ridge will steer Cristina toward the west-northwest during the next few days.  On its anticipated track Tropical Storm Cristina will move away from the west coast of Mexico.

Tropical Storm Narda Brings Rain to Mexico

Tropical Storm Narda brought rain to parts of the west coast of Mexico on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Depression Narda was located at latitude 19.1°N and longitude 103.3°W which put it about 55 miles (90 km) east of Manzanillo, Mexico.  Narda was moving toward the northwest at 20 m.p.h. (32 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 1002 mb.

The center of former Tropical Storm Narda made landfall on the west coast of Mexico between Lazaro Cardenas and Manzanillo on Sunday.  Narda weakened to a tropical depression after the center moved over land.  Bands of showers and thunderstorms were dropping locally heavy rain along and just inland of the portion of the coast from Acapulco to Manzanillo, Mexico.  The rain could be heavy enough in some locations to cause flash floods.

Tropical Depression Narda is moving around the western side of a high pressure system over Mexico.  The high is steering Narda quickly toward the northwest.  Tropical Depression Narda will move along the west coast of Mexico during the next day or two.  The center of Narda could move back over the Eastern North Pacific Ocean near Cabo Corrientes.  Tropical Depression Narda will continue to drop heavy rain near the coast while it moves toward the northwest.

Tropical Storm Narda Forms South of Mexico

Tropical Storm Narda formed south of Mexico late on Saturday.  At 11:00 p.m. EDT on Saturday the center of Tropical Storm Narda was located at latitude 15.4°N and longitude 100.6°W which put it about 115 miles south-southwest of Acapulco, Mexico.  Narda was moving toward the northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 40 m.p.h. (15 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1000 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Acapulco to Cabo Corrientes, Mexico.

An area of low pressure exhibited more organization late on Saturday and the National Hurricane Center designated the system as Tropical Storm Narda.  A low level center of circulation formed within the area of low pressure.  Bands of showers and thunderstorms developed and began to revolve around the center of circulation.  Many of the stronger thunderstorms were in bands in the western half of the circulation.  Bands in the eastern half of the circulation contained more showers and lower clouds.  An area of winds to tropical storm force was occurring about 120 miles (195 km) southeast of the center of circulation.

Tropical Storm Narda will move through an environment only marginally favorable for intensification on Sunday.  Narda will move over water where the Sea Surface Temperature is near 29°C.  However, an upper level ridge over Mexico will produce northeasterly winds which will blow toward the top of the circulation.  Those winds will cause moderate vertical wind shear which will inhibit intensification.  In addition, the circulation could draw drier air into the northern portion of the tropical storm.  Tropical Storm Narda is not likely to strengthen much during the next 12 to 24 hours.

The ridge over Mexico will steer Tropical Storm Narda toward the northwest during the next several days.  On its anticipated track Tropical Storm Narda will approach the coast of Mexico near Lazaro Cardenas in about 12 hours.  Narda will move along the coast toward Cabo Corrientes.  Tropical Storm Narda could drop locally heavy rain in parts of Guerrero, Michoacan, Colima and Jalisco.  The rain could cause flash floods in some locations.

Willa Rapidly Intensifies Into a Major Hurricane, Warnings Issued for Mexico

Hurricane Willa intensified rapidly into a major hurricane on Sunday and Warnings were issued for Mexico.  At 11: 00 p.m. EDT on Sunday the center of Hurricane Willa was located at latitude 17.7°N and longitude 107.2°W which put it about 210 miles (340 km) south-southwest of Cabo Corrientes, Mexico.  Willa was moving toward the north-northwest at 7 m.p.h. (11 km/h).  The maximum sustained wind speed was 145 m.p.h. (230 km/h) and there were wind gusts to 170 m.p.h. (275 km/h).  The minimum surface pressure was 941 mb.  Hurricane Willa was a Category 4 hurricane on the Saffir-Simpson Scale.

A Hurricane Warning was in effect for the portion of the coast from San Blas to Mazatlan, Mexico.  A Tropical Storm Warning was in effect for the portion of the coast from Playa Perula to San Blas.  A Tropical Storm Warning was also in effect for the portion of the coast from Mazatlan to Bahia Tempehuaya.

Hurricane Willa intensified from a tropical storm to a Category 4 hurricane in 24 hours.  A small circular eye formed at the center of Hurricane Willa.  The eye was surround by a ring of strong thunderstorms and the strongest winds were occurring in that ring of storms.  Several bands of showers and thunderstorms were revolving around the core of Hurricane Willa.  Storms near the core were generating strong upper level divergence which was pumping large quantities of mass away from the hurricane.  The strong divergence allowed the surface pressure to decrease quickly and that caused the wind speeds to increase rapidly.

Willa is a small hurricane.  Winds to hurricane force only extend out about 25 miles (40 km) from the center of Hurricane Willa.  Winds to tropical storm force only extend out about 90 miles (145 km) from the center of circulation.  The Hurricane Intensity Index (HII) for Hurricane Willa is 29.9.  The Hurricane Size Index (HSI) is 8.2 and the Hurricane Wind Intensity Size Index (HWISI) is 38.1.

Hurricane Willa will move through an environment favorable for intensification during the next 12 to 24 hours.  Willa will move over water where the Sea Surface Temperature is near 29°C.  It will move through a region where the upper level winds are weak and there will not be much vertical wind shear.  Hurricane Willa could strengthen to a Category 5 hurricane on the Saffir-Simpson Scale during the next 12 hours.  An upper level trough near the west coast of the U.S. will produce southwesterly winds which will start to affect Hurricane Willa in about 24 hours.  Those winds will cause vertical wind shear, which will cause Willa to start to weaken.

Hurricane Willa will move around the western end of a ridge of high pressure over Mexico.  The ridge will steer Willa toward the north on Monday.  The upper level trough near the west coast of the U.S. will turn Hurricane Willa toward the northeast on Tuesday.  On its anticipated track Hurricane Willa could make landfall on the coast of Mexico on Tuesday night.  Willa could be a major hurricane when it approaches the coast.  It will be capable of causing major wind damage and a significant storm surge along the coast.  Willa will also drop locally heavy rain and it could flash floods when it moves inland over Mexico.

Elsewhere over the Eastern North Pacific Ocean Tropical Storm Vicente was moving near the southeastern periphery of Hurricane Willa.  At 11:00 p.m. EDT on Sunday the center of Tropical Storm Vicente was located at latitude 13.9°N and longitude 98.7°W which put it about 220 miles (355 km) south-southeast of Acapulco, Mexico.  Vicente was moving toward the west 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.
