Former Hurricane Kristy weakened to a tropical storm over the Eastern North Pacific Ocean west of Baja California on Saturday.  At 5:00 p.m. EDT on Saturday the center of Tropical Storm Kristy was located at latitude 20.7°N and longitude 129.2°W which put the center about 1245 miles (2005 km) west of the southern tip of Baja California.  Kristy was moving toward the northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 65 m.p.h. (105 km/h) and there were wind gusts to 80 m.p.h. (130 km/h).  The minimum surface pressure was 993 mb.

Former Hurricane Kristy moved under the eastern side of an upper level trough east of Hawaii.  The upper level trough produced strong southwesterly winds that blew across the top of Kristy’s circulation.  Those winds caused strong vertical wind shear.  The wind shear blew the tops off of many of the thunderstorms in Tropical Storm Kristy, which caused Kristy to weaken rapidly.

The former eye of then Hurricane Kristy was still visible on satellite images.  However, the eye was surrounded by a ring of low clouds.  A few thunderstorms were still occurring in bands in the northern side of Tropical Storm Kristy.  Most of the bands revolving around the center of Kristy’s circulation consisted primarily of showers and lower clouds.

Despite the strong vertical wind shear, the distribution of wind speeds in Tropical Storm Kristy was fairly symmetrical.  Winds to tropical storm force extended out 115 miles (185 km) from the center of Kristy’s circulation.

Tropical Storm 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 25°C.  The upper level trough east of Hawaii will continue to cause strong vertical wind shear.  Tropical Storm Kristy will continue to weaken during the next 24 hours.

The upper level trough east of Hawaii will steer Tropical Storm Kristy toward the northwest during the next 12 hours.  After the last thunderstorms in Kristy’s circulation dissipate, the tropical storm will be steered by the winds in the lower levels of the atmosphere.  A high pressure system over the Eastern North Pacific Ocean will steer Kristy toward the west-southwest on Sunday.  On its anticipated track, Tropical Storm Kristy will remain far from any land area.
