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.
