Hurricane Linda Strengthens to Cat. 4

Hurricane Linda strengthened to Category 4 on the Saffir-Simpson Scale over the Eastern North Pacific Ocean on Saturday. At 5:00 p.m. EDT on Saturday the center of Hurricane Linda was located at latitude 19.1°N and longitude 117.0°W which put it about 525 miles (850 km) west-southwest of the southern tip of Baja California. Linda was moving toward the west-northwest at 13 m.p.h. (21 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 150 m.p.h. (240 km/h). The minimum surface pressure was 950 mb.

Hurricane Linda continued to strengthen on Saturday and it reached Category 4 on the Saffir-Simpson Scale. A circular eye with a diameter of 18 miles (30 km) was at the center of Linda. 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 Linda. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Linda was symmetrical. Winds to hurricane force extended out 25 miles (40 km) from the center of Linda. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) for Linda was 25.1. The Hurricane Size Index (HSI) was 10.2 and the Hurricane Wind Intensity Size Index (HWISI) was 35.3.

Hurricane Linda will begin to move over slightly cooler water on Sunday and it will start to weaken. Linda will move through an environment where the upper level winds are weak and there will be little vertical wind shear. So, Hurricane Linda is likely to weaken gradually during the next 36 hours.

Hurricane Linda will move south of a subtropical high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Linda toward the west during the next few days. On its anticipated track Hurricane Linda will move toward the Central Pacific Ocean.

Linda Rapidly Intensifies to a Major Hurricane

Hurricane Linda rapidly intensified to a major hurricane south of Baja California on Friday afternoon. At 5:00 p.m. EDT on Friday the center of Hurricane Linda was located at latitude 17.5°N and longitude 112.9°W which put it about 420 miles (675 km) south-southwest of the southern tip of Baja California. Linda was moving toward the west-northwest at 14 m.p.h. (22 km/h). The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (220 km/h). The minimum surface pressure was 965 mb.

Hurricane Linda rapidly intensified into a major hurricane over the Eastern North Pacific Ocean on Friday afternoon. A circular eye with a diameter of 23 miles (35 km) was evident on visible satellite images. 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 Linda. Storms near the core generated strong upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 25 miles (40 km) from the center of Linda. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation.

Hurricane Linda will move through an environment favorable for intensification during the next 12 hours. Linda will move over water where the Sea Surface Temperatures are near 28°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Linda could continue to intensify during the next 12 hours. Linda will start to move over slightly cooler water on Saturday, which is likely to cause the hurricane to start to weaken.

Hurricane Linda will move around the southern side of a subtropical high pressure system over the Eastern North Pacific Ocean. The high will steer Linda toward the west during the next few days. On its anticipated track Hurricane Linda will move farther away from Mexico.

Linda Strengthens to a Hurricane

Former Tropical Storm Linda strengthened to a hurricane over the Eastern North Pacific Ocean on Thursday morning. At 11:00 a.m. EDT on Thursday the center of Hurricane Linda was located at latitude 14.8°N and longitude 107.7°W which put it about 365 miles (590 km) southwest of Manzanillo, Mexico. Linda was moving toward the west-northwest at 8 m.p.h. (13 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 Linda strengthened on Thursday morning and the National Hurricane Center upgraded it to a hurricane. The inner end of a rainband wrapped around the eastern side of the center of Linda and satellite images intermittently depicted the potential formation of an eye. Most of the thunderstorms in Hurricane Linda were occurring near the center of circulation and in bands in the southern half of the hurricane. Bands in the northern half of Linda consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away from the hurricane. Winds to hurricane force extended out 20 miles (30 km) in the northeastern quadrant of Linda. Winds to tropical storm force extended out 105 miles (165 km) from the center of circulation.

Hurricane Linda will move through an environment favorable for intensification during the next 36 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 near Baja California. The ridge will produce northeasterly winds that will blow toward the top of Hurricane Linda’s circulation. Those winds will cause some vertical wind shear. The wind shear will somewhat inhibit intensification but the shear will not strong enough to prevent Linda from strengthening.

Hurricane 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 Hurricane Linda will pass south of Baja California.

Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Kevin was weakening west of Baja California. At 11:00 a.m. EDT on Thursday the center of Tropical Depression Kevin was located at latitude 23.2°N and longitude 120.6°W which put it about 465 miles (750 km) southwest of Punta Eugenia, Mexico. Kevin was moving toward the west-northwest at 14 m.p.h. (22 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 1007 mb.

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.

Hurricane Genevieve Brings Wind and Rain to Baja California

Hurricane Genevieve brought wind and rain to southern Baja California on Thursday morning.  At 11:00 a.m. EDT on Thursday the center of Hurricane Genevieve was located at latitude 23.3°N and longitude 111.4°W which put it about 120 miles (195 km) south-southeast of Cabo San Lazaro, Mexico.  Genevieve 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 984 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Los Barriles to Cabo San Lazaro, Mexico.  A Tropical Storm Watch was in effect for the portion of the coast from Los Barriles to La Paz, Mexico.

The center of Hurricane Genevieve passed just southwest of the southern tip of Baja California on Thursday morning.  A weather station at the Cabo San Lucas Marina reported a wind gust of 90 m.p.h. (145 km/h).  Bands of thunderstorms were dropping heavy rain on parts of southern Baja California.  There were reports of flash floods in some locations.

Hurricane Genevieve will weaken during the next several days as it moves over cooler water.  Genevieve will move over water where the Sea Surface Temperatures are cooler than 26°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Genevieve will weaken gradually as it moves over cooler water.

Hurricane Genevieve will move around the southwestern part of a ridge of high pressure over the southwestern U.S. and northern Mexico.  The ridge will steer Genevieve toward the northwest.  On its anticipated track Hurricane Genevieve will move parallel to the west coast of Baja California.  Genevieve will continue to bring gusty winds to the southern part of Baja California.  It will also drop move heavy rain and additional flash floods are likely.

Genevieve Prompts Hurricane Warning for Baja California

A potential close approach of Hurricane Genevieve prompted the issuance of a Hurricane Warning for the southern tip of Baja California.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Genevieve was located at latitude 20.9°N and longitude 109.7°W which put it about 140 miles (225 km) south of the southern tip of Baja California.  Genevieve was moving toward the north-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 115 m.p.h. (185 km/h) and there were wind gusts to 135 m.p.h. (220 km/h).  The minimum surface pressure was 959 mb.

A Hurricane Warning was in effect for the portion of the coast from Los Barriles to Todos Santos, Mexico.  A Tropical Storm Warning was in effect for the portion of the coast from Todos Santos to Cabo San Lazaro, Mexico.  A Tropical Storm Watch was in effect for the portion of the coast from Los Barriles to La Paz, Mexico.

Hurricane Genevieve continued to exhibit a well organized circulation.  A circular eye was present at the center of circulation.  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 Genevieve.  Storms near the core of the circulation were generating strong upper level divergence was pumping mass away from the hurricane.

Hurricane force winds extended out 35 miles (55 km) from the center of Genevieve.  Tropical Storm force winds extended out 140 miles (225 km) from the center of circulation.  The Hurricane Intensity Index (HII) for Hurricane Genevieve was 20.6.  The Hurricane Size Index (HSI) was 13.4 and the Hurricane Wind Intensity Size Index (HWISI) was 34.0.

Hurricane Genevieve will move through an environment less favorable for a major hurricane during the next few days.  Genevieve will move over water where the Sea Surface Temperatures are cooler than 27°C.  It will move through a region where the upper level winds are weak and there will be little vertical wind shear.  Hurricane Genevieve is likely to weaken when the core starts to move over cooler water.

Hurricane Genevieve will move around the southwestern part of an ridge of high pressure over the southwestern U.S. and northern Mexico.  The ridge will Genevieve toward the north-northwest during the next 24 hours.  On its anticipated track the core of Hurricane Genevieve could be near the southern tip of Baja California in about 18 hours.  Genevieve will cause gusty winds over the southern part of Baja California.  It will also drop locally heavy rain which could cause flash floods.

Hurricane Genevieve Rapidly Intensifies to Cat. 4

Hurricane Genevieve rapidly intensified to Category 4 on the Saffir-Simpson Scale over the Eastern North Pacific Ocean.  At 8:00 a.m. EDT on Tuesday the center of Hurricane Genevieve was located at latitude 17.7°N and longitude 107.6°W which put it about 390 miles (630 km) south-southeast of the southern tip of Baja California.  Genevieve was moving toward the northwest a 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 950 mb.

A Tropical Storm Warning was in effect for the portion of the coast from Los Barriles to Todos Santos, Mexico.  Tropical Storm Watches were in effect for the portion of the coast from Los Barriles to La Paz and from Todos Santos to Sante Fe, Mexico.

Hurricane Genevieve continued to intensify rapidly during the past 24 hours and it reached Category 4 on the Saffir-Simpson Scale.  A circular eye with a diameter of 20 miles (32 km) formed at the center of Genevieve.  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 Genevieve.  Storms near the core were generating strong upper level divergence which was pumping mass away from the hurricane in all directions.

The circulation around Hurricane Genevieve increased in size during the past 24 hours.  Winds to hurricane force extended out 30 miles (50 km) from the center of circulation.  Winds to tropical storm force extended out 150 miles (240 km) from the center.  The Hurricane Intensity Index (HII) for Hurricane Genevieve was 25.1.  The Hurricane Size Index (HSI) was 10.9 and the Hurricane Wind Intensity Size Index (HWISI) was 36.0.

Hurricane Genevieve will move through an environment very favorable for strong hurricanes during the next 24 hours.  Genevieve 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 be little vertical wind shear.  Hurricane Genevieve could strengthen further during the next 24 hours.  If a rainband wraps around the existing eye and eyewall, then an eyewall replacement cycle could occur.  The eyewall replacement cycle would cause Hurricane Genevieve to weaken.

Hurricane Genevieve will move south of a ridge of high pressure over the southwestern U.S. and northern Mexico.  The high will steer Genevieve toward the northwest during the next several days.  On its anticipated track the center of Hurricane Genevieve will pass west of Baja California.  However, Genevieve could come close enough to the coast to bring tropical storm force winds and locally heavy rain to the southern portion of Baja California.  Locally heavy rain could cause flash floods in some locations.

Hurricane Genevieve will move through an environment very favorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperature is 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 Genevieve will continue to intensify rapidly and it could strengthen into a major hurricane during the next 24 hours.

Hurricane Genevieve will move south of a ridge over high pressure over the southwestern U.S. and northern Mexico.  The ridge will steer Genevieve toward the west-northwest during the next few days.  On its anticipated track Hurricane Genevieve could be south of Baja California on Wednesday.

Tropical Storm Genevieve Spins Up Quickly South of Mexico

Tropical Storm Genevieve spun up quickly south of Mexico on Sunday.  At 5:00 p.m. EDT on Sunday the center of Tropical Storm Genevieve was located at latitude 12.2°N and longitude 99.2°W which put it about 410 miles (665 km) south-southeast of Zihuatanejo, Mexico.  Genevieve was moving toward the west-northwest at 20 m.p.h. (32 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 1004 mb.

The circulation around former Tropical Depression Twelve-E organized quickly on Sunday afternoon and the National Hurricane Center upgraded the system to Tropical Storm Genevieve.  More thunderstorms developed near the center of circulation.  Bands of showers and thunderstorms were revolving around the center of Genevieve.  Storms near the center were generating upper level divergence which was pumping mass away from the tropical storm.  Winds to tropical storm force extended out 100 miles (160 km) from the center of circulation.

Tropical Storm Genevieve will move through an environment very favorable for intensification during the next several days.  Genevieve will move over water where the Sea Surface Temperature is near 30°C.  It will move through a region where the upper level winds will be weak and there will be little vertical wind shear.  Tropical Storm Genevieve will intensify rapidly.  Genevieve will strengthen into a hurricane within 24 hours and it could intensify into a major hurricane during the next 48 hours.

Tropical Storm Genevieve will move around the southern side of a ridge of high pressure over the southwestern U.S. and northern Mexico.  The ridge will steer Genevieve toward the west-northwest.  On its anticipated track Tropical Storm Genevieve could pass south of the Baja California during the middle of the week.

Tropical Storm Fausto Develops Southwest of Baja California

Tropical Storm Fausto developed southwest of Baja California on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Tropical Storm Fausto was located at latitude 20.7°N and longitude 119.6°W which put it about 640 miles (1020 km) west-southwest of the southern tip of Baja California.  Fausto was moving toward the 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 1004 mb.

More thunderstorms formed near the center of former Tropical Depression Eleven-E on Sunday morning and the National Hurricane Center upgraded the system to Tropical Storm Fausto.  The distribution of thunderstorms around Fausto was asymmetrical.  Many of the thunderstorms were occurring in bands in the northern half of the circulation.  The strongest winds were occurring in those bands of thunderstorms.  Bands in the southern half of the tropical storm consisted primarily of showers and lower clouds.  Winds to tropical storm force extended out 50 miles (80 km) in the northern half of the circulation.  The wind in the southern half of the circulation was blowing at less than tropical storm force.

Tropical Storm Fausto will move through an environment unfavorable for intensification.  Fausto will move over water where the Sea Surface Temperature is near 25°C.  An upper level trough west of Tropical Storm Fausto will produce southerly winds which will blow toward the top of the circulation.  Those winds will cause vertical wind shear which will also inhibit potential intensification.  Tropical Storm Faust is likely to weaken slowly when it moves over cooler water.

Tropical Storm Fausto will move south of a high pressure system over the Eastern North Pacific Ocean.  The high will steer Fausto toward the west during the next several days.  On its anticipated track Tropical Storm Fausto will move away from Baja California.

Elsewhere over the Eastern North Pacific Ocean, Tropical Depression Twelve-E spun up quickly south of Mexico and Tropical Depression Ten-E stalled between Mexico and Hawaii.  At 11:00 a.m. EDT on Sunday the center of Tropical Depression Twelve-E was located at latitude 11.3°N and longitude 97.3°W which put it about 525 miles (850 km) southeast of Zihuatanejo, Mexico.  The depression was moving toward the north-northwest at 18 m.p.h. (30 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 1005 mb.  Tropical Depression Twelve-E is forecast to intensify quickly and it could strengthen into a major hurricane during the next several days.

At 11:00 a.m. EDT on Sunday the center of Tropical Depression Ten-E was located at latitude 13.7°N and longitude 134.0°W which put it about 1700 miles (2735 km) west-southwest of the southern tip of Baja California.  The depression was moving toward the north-northwest 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.
