Hurricane Kristy Weakens

Hurricane Kristy weakened over the Eastern North Pacific Ocean on Friday morning,  At 11:00 a.m. EDT on Friday the center of Hurricane Kristy was located at latitude 15.6°N and longitude 124.8°W which put the center about 1085 miles (1750 km) west-southwest of the southern tip of Baja California.  Kristy was moving toward the west-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 952 mb.

Hurricane Kristy weakened over the Eastern North Pacific Ocean on Friday morning after reaching Category 5 on the Saffir-Simpson Scale on Thursday.  Clouds were developing inside the eye at the center of Kristy’s circulation.  The eye was still surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Kristy.  Storms near the core of Kristy’s circulation generated less upper level divergence than they did on Thursday.  The removal of less mass caused the surface pressure to increase.

The circulation around Hurricane Kristy continued to be small.  Winds to hurricane force extended out 30 miles (50 km) from the center of Kristy’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Kristy.

Hurricane Kristy will move through an environment that will be unfavorable for intensification during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southern end of an upper level trough east of Hawaii.  The upper level trough will produce southwesterly winds that will blow toward the top of Kristy’s circulation.  Those upper level winds will cause the vertical wind shear to increase.  Hurricane Kristy will continue to weaken during the next 24 hours because of the increased vertical wind shear.

Hurricane Kristy will move around the southwestern part of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Kristy toward the northwest during the next 24 h.  On its anticipated track, Hurricane Kristy will continue to remain far from any land mass.

Hurricane Kristy Intensifies to Cat. 5

Hurricane Kristy intensified to Category 5 on the Saffir-Simpson Scale over the Eastern North Pacific Ocean southwest of Baja California on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Hurricane Kristy was located at latitude 14.2°N and longitude 121.6°W which put the center about 970 miles (1565 km) southwest of the southern tip of Baja California.  Kristy was moving toward the west at 16 m.p.h. (26 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 926 mb.

Hurricane Kristy looked like a Category 5 hurricane on visible satellite images on Thursday afternoon.  A circular eye with a diameter of 17 miles (28 km) was at the center of Kristy’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Kristy.  Storms near the core 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.

The circulation around Hurricane Kristy was small.  Winds to hurricane force extended out 25 miles (40 km) from the center of Kristy’s circulation.  Winds to tropical storm force extended out 105 miles (165 km) from the center of Hurricane Kristy.

The Hurricane Intensity Index (HII) for Hurricane Kristy was 35.0.  The Hurricane Size Index (HSI) was 8.2 and the Hurricane Wind Intensity Size Index (HWISI) was 8.2.  Hurricane Kristy is smaller than Hurricane Milton was when Milton was over the Gulf of Mexico.

Hurricane Kristy will move through an environment that will become less favorable for a powerful hurricane during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 29°C.  It will move toward the southern end of an upper level trough between Hawaii and California.  The upper level trough will produce southwesterly winds that will start to affect Hurricane Kristy on Friday.  Those upper level winds will cause the vertical wind shear to increase.  Hurricane Kristy will start to weaken when the vertical wind shear increases.

Hurricane Kristy will move around the southwestern part of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer Kristy toward the northwest during the next 24 h.  On its anticipated track, Hurricane Kristy will continue to remain far from any land mass.

Kristy Rapidly Intensifies to a Major Hurricane South of Baja California

Hurricane Kristy rapidly intensified to a major hurricane over the Eastern North Pacific Ocean south of Baja California on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Hurricane Kristy was located at latitude 14.3°N and longitude 113.9°W which put the center about 650 miles (1045 km) south-southwest of the southern tip of Baja California.  Kristy was moving toward the west at 20 m.p.h. (32 km/h).  The maximum sustained wind speed was 125 m.p.h. (200 km/h) and there were wind gusts to 150 m.p.h. (240 km/h).  The minimum surface pressure was 954 mb.

Hurricane Kristy continued to intensify rapidly on Wednesday morning.  A small circular eye was at the center of Kristy’s circulation.  The eye was surrounded by a ring of thunderstorms and the strongest winds were occurring in that ring of storms.  Bands of showers and thunderstorms were revolving around the core of Hurricane Kristy.  Storms near the core 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 circulation around Hurricane Kristy was small.  Winds to hurricane force extended out 20 miles (30 km) from the center of Kristy’s circulation.  Winds to tropical storm force extended out 80 miles (130 km) from the center of Hurricane Kristy.

Hurricane Kristy will move through an environment favorable for intensification during the next 24 hours. Kristy will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the axis of an upper level ridge over the Eastern North Pacific.  The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Hurricane Kristy will intensify during the next 24 hours.  Kristy could continue to intensify rapidly. Hurricane Kristy could to strengthen to Category 5 on the Saffir-Simpson Scale on Thursday.

Hurricane Kristy will move around the southern side of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will continue to steer Kristy toward the west during the next 24 h.  On its anticipated track, Hurricane Kristy will continue to move farther away from Mexico.

Kristy Rapidly Intensifies to a Hurricane

Former Tropical Storm Kristy rapidly intensified to a hurricane over the Eastern North Pacific Ocean south of Baja California on Tuesday.  At 5:00 p.m. EDT on Tuesday the center of Hurricane Kristy was located at latitude 14.7°N and longitude 108.5°W which put the center about 550 miles (890 km) south of the southern tip of Baja California.  Kristy was moving toward the west 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. (145 km/h).  The minimum surface pressure was 988 mb.

Former Tropical Storm Kristy rapidly intensified to a hurricane on Tuesday.  The inner end of a rainband wrapped around the center of Kristy’s circulation.  A circular eye formed at the center of Hurricane Kristy.  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 center of Kristy’s circulation.  Storms near the center of Kristy generated strong upper level divergence that pumped large quantities of mass away from the hurricane.  The removal of large amounts of mass caused the surface pressure to decrease rapidly.

The circulation around Hurricane Kristy became more symmetrical on Tuesday.  Winds to hurricane force extended out 20 miles (30 km) in the northeastern quadrant of Kristy’s circulation.  Winds to tropical storm force extended out 70 miles (110 km) from the center of Hurricane Kristy.

Hurricane Kristy will move through an environment favorable for intensification during the next 24 hours.  Kristy will move over water where the Sea Surface Temperatures are near 29°C.  It will move under the axis of an upper level ridge over the Eastern North Pacific. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.  Hurricane Kristy will intensify during the next 24 hours.  Kristy could continue to intensify rapidly.  Hurricane Kristy is likely to strengthen to a major hurricane on Wednesday.
