Hurricane Genevieve Continues to Weaken

Hurricane Genevieve continued to weaken as it moved over the Eastern North Pacific Ocean southwest of Baja California on Wednesday.  At 11:00 p.m. EDT on Wednesday the center of Hurricane Genevieve was located at latitude 19.6°N and longitude 120.8°W which put the center about 735 miles (1185 km) west-southwest of southern tip of Baja California.  Genevieve was moving toward the west-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 970 mb.

Hurricane Genevieve continued to weaken gradually on Wednesday as it moved over cooler water in the Eastern North Pacific Ocean southwest of Baja California.  An eye was no longer visible on satellite imagery, but thunderstorms were still occurring near the center of Genevieve’s circulation.  Bands of showers and thunderstorms were revolving around the center of Hurricane Genevieve.  Storms near the center of Genevieve still generated upper level divergence that pumped mass away from the hurricane.  However, the removal of mass in the upper levels was less than the convergence of mass in the lower levels of the atmosphere.  So, the surface pressure increased on Wednesday.

The distribution of wind speeds around Hurricane Genevieve was fairly symmetrical.  Winds to hurricane force extended out 30 miles (50 km) from the center of Genevieve’s circulation.  Winds to tropical storm force extended out 140 miles (220 km) from the center of Hurricane Genevieve.

Hurricane Genevieve will move through an environment that will be unfavorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperatures are near 25°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 weaken on Thursday as it moves over cooler water.  Genevieve could weaken to a tropical storm by Friday.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the west-northwest during the next 24 hours.  On its anticipated track, Hurricane Genevieve will move farther away from Baja California.

Tropical Storm Fausto Passes Northeast of Hawaii

Tropical Storm Fausto was weakening as it passed northeast of Hawaii on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Tropical Storm Fausto was located at latitude 22.5°N and longitude 152.2°W which put the center about 270 miles (435 km) northeast of Hilo, Hawaii.  Fausto was moving toward the west-northwest at 12 m.p.h. (19 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.

Tropical Storm Fausto was weakening as it passed northeast of Hawaii on Tuesday afternoon.  An upper level trough that was located north of Hawaii was producing strong southwesterly winds that were blowing across the top of Fausto’s circulation.  Those winds were causing strong vertical wind shear.  The strong upper level winds were also blowing the tops off of many of the thunderstorms in Tropical Storm Fausto.

Thunderstorms were still occurring in bands in the eastern edge of Tropical Storm Fausto.  Bands in the other parts of Fausto’s circulation consisted primarily of showers and lower clouds.  There were no thunderstorms near the center of Fausto to generate upper level divergence to pump mass away from the tropical storm.  Convergence of mass in the lower levels of the atmosphere was causing the surface pressure to increase.

The strongest winds were blowing on the northern side of Tropical Storm Fausto.  Winds to tropical storm force extended out 140 miles (220 km) in the northern side of Fausto’s circulation.  Winds to tropical storm force only extended out 70 miles (110 km) in the southern side of Tropical Storm Fausto.

Tropical Storm Fausto will move through an environment that will be unfavorable for intensification during the next 24 hours.  Fausto will move over water where the Sea Surface Temperatures are near 26°C.  However, the upper level trough north of Hawaii will continue to cause strong vertical wind shear.  Tropical Storm Fausto will continue to weaken steadily during the next 24 hours.  Fausto is likely to weaken to a tropical depression on Wednesday.

Tropical Storm Fausto will move around the southern side of a high pressure system that is over the Central North Pacific Ocean.  The high pressure system will steer Fausto toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Fausto will continue to pass north of Hawaii on Wednesday.

Elsewhere, Hurricane Genevieve was weakening gradually as it moved southwest of Baja California.  At 5:00 p.m. EDT on Tuesday the center of Hurricane Genevieve was located at latitude 18.0°N and longitude 116.9°W which put the center about 565 miles (910 km) southwest of southern tip of Baja California.  Genevieve was moving toward the west-northwest at 9 m.p.h. (15 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h). The minimum surface pressure was 955 mb.

Hurricane Genevieve Intensifies to Cat. 5

Hurricane Genevieve intensified to Category 5 on the Saffir-Simpson Scale on Sunday night as it moved over the Eastern North Pacific Ocean south of Baja California.  At 5:00 a.m. EDT on Monday the center of Hurricane Genevieve was located at latitude 15.5°N and longitude 112.2°W which put the center about 530 miles (855 km) south-southwest of southern tip of Baja California.  Genevieve was moving toward the northwest at 13 m.p.h. (21 km/h).  The maximum sustained wind speed was 160 m.p.h. (260 km/h) and there were wind gusts to 190 m.p.h. (305 km/h).  The minimum surface pressure was 925 mb.

Hurricane Genevieve intensified to Category 5 on Sunday night.  A circular eye with a diameter of 23 miles (37 km) was at the center of Genevieve’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 Genevieve’s circulation.  Storms near the core of Genevieve generated strong upper level divergence that pumped large amounts of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The distribution of wind speeds in Hurricane Genevieve became more symmetrical on Sunday night.  Winds to hurricane force extended out 45 miles (75 km) from the center of Genevieve’s circulation.  Winds to tropical storm force extended out 195 miles (315 km) from the center of Hurricane Genevieve.

The Hurricane Intensity Index (HII) for Hurricane Genevieve was 35.0.  The Hurricane Size Index (HII) was 16.5 and the Hurricane Wind Intensity Size Index (HWISI) was 51.5.  Hurricane Genevieve was similar in size and intensity to Hurricane Michael when Michael hit Northwest Florida in 2018.

Hurricane Genevieve will move into an environment that will become slighyly less favorable for an intense hurricane during the next 24 hours.  Genevieve 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.  However, Genevieve will start to move into a region where the air is a little drier later today.  Hurricane Genevieve is likely to start to weaken when it moves into the region of drier air.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the northwest during the next 24 hours. On its anticipated track, Hurricane Genevieve will move parallel to the coast of Baja California.

Elsewhere, Hurricane Fausto continued to weaken slowly as it moved over the Central North Pacific Ocean east of Hawaii.  At 5:00 a.m. EDT on Monday the center of Hurricane Fausto was located at latitude 20.4°N and longitude 144.8°W which put the center about 670 miles (1080 km) east of Hilo, Hawaii.  Fausto was moving toward the west-northwes at 14 m.p.h. (24 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 988 mb.

Genevieve Rapidly Intensifies to a Major Hurricane

Hurricane Genevieve rapidly intensified to a major hurricane over the Eastern North Pacific Ocean southwest of Mexico on Sunday morning.  At 11:00 a.m. EDT on Sunday the center of Hurricane Genevieve was located at latitude 13.4°N and longitude 109.4°W which put the center about 515 miles (825 km) southwest of Manzanillo, Mexico.  Genevieve was moving toward the west-northwest at 16 m.p.h. (26 km/h).  The maximum sustained wind speed was 120 m.p.h. (195 km/h) and there were wind gusts to 140 m.p.h. (220 km/h).  The minimum surface pressure was 963 mb.

A circular eye with a diameter of 20 miles (32 km) formed at the center of Hurricane Genevieve.  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 Genevieve’s circulation.  Storms near the core of Genevieve generated strong upper level divergence that pumped large amounts of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

Winds to hurricane force extended out 45 miles (75 km) in the northern side of Hurricane Genevieve.  Winds to hurricane force extended out 15 miles (25 km) in the southern side of Genevieve’s circulation.  Winds to tropical storm force extended out 195 miles (315 km) from the center of Hurricane Genevieve.

Hurricane Genevieve will move through an environment favorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperatures are 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 will intensify during the next 24 hours.  Genevieve could continue to intensify rapidly during the next few hours.   Hurricane Genevieve could strengthen to a Category 5 hurricane on the Saffir-Simpson Scale.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Genevieve will move parallel to the west coast of Mexico.

Elsewhere, Hurricane Fausto was weakening slowly as it moved over the Central North Pacific Ocean.  At 11:00 a.m. EDT on Sunday the center of Hurricane Fausto was located at latitude 19.9°N and longitude 141.1°W which put the center about 910 miles (1465 km) east of Hilo, Hawaii.  Fausto was moving toward the west at 14 m.p.h.

Genevieve Strengthens to a Hurricane

Former Tropical Storm Genevieve strengthened to a hurricane over the Eastern North Pacific Ocean southwest of Mexico on Saturday.  At 11:00 p.m. EDT on Saturday the center of Hurricane Genevieve was located at latitude 12.1°N and longitude 106.7°W which put the center about 500 miles (810 km) south-southwest of Manzanillo, Mexico.  Genevieve was moving toward the west-northwest at 15 m.p.h. (24 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 987 mb.

Former Tropical Storm Genevieve strengthened to a hurricane on Saturday.  The inner end of a rainband wrapped around the eastern and northern sides of the center of Genevieve’s circulation.  An eye appeared to be forming at the center of Hurricane Genevieve.  Bands of showers and thunderstorms were revolving around the center of Genevieve’s circulation.  Storms near the center of Genevieve generated upper level divergence that pumped mass away from the hurricane.  The removal of mass caused the surface pressure to decrease.

The strongest winds were occurring in the section of the rainband that wrapped around the northeastern part of the center of Hurricane Genevieve.  Winds to hurricane force extended out 20 miles in the northeastern quadrant of Genevieve’s circulation.  Winds to tropical storm force extended out 125 miles (200 km) from the center of Hurricane Genevieve.

Hurricane Genevieve will move through an environment favorable for intensification during the next 24 hours.  Genevieve will move over water where the Sea Surface Temperatures are 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 will intensify during the next 24 hours.  Genevieve could intensify rapidly at times.  Genevieve is likely to strengthen to a major hurricane by early next week.

Hurricane Genevieve will move around the southwestern part of a high pressure system that is over the Southwest U.S.  The high pressure system will steer Genevieve toward the northwest during the next 24 hours.  On its anticipated track, Hurricane Genevieve will move parallel to the west coast of Mexico.

Elsewhere, Hurricane Fausto was nearing the Central Pacific Ocean.  At 11:00 p.m. EDT on Saturday the center of Hurricane Fausto was located at latitude 19.5°N and longitude 138.8°W which put the center about 1060 miles (1702 km) east of Hilo, Hawaii.  Fausto was moving toward the west at 13 m.p.h.

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.

Genevieve Rapidly Intensifies into a Hurricane

Former Tropical Storm Genevieve rapidly intensified into a hurricane southwest of Mexico on Monday morning.  At 11:00 a.m. EDT on Monday the center of Hurricane Genevieve was located at latitude 14.3°N and longitude 103.0°W which put it about 250 miles (400 km) south-southwest of Zihuantanejo, Mexico.  Genevieve was moving toward the west-northwest at 18 m.p.h. (30 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. (120 km/h).  The minimum surface pressure was 992 mb.
