Hurricane Bonnie churned over the Eastern North Pacific Ocean southwest of Baja California on Thursday night. At 11:00 p.m. EDT on Thursday the center of Hurricane Bonnie was located at latitude 18.1°N and longitude 116.9°W which put it about 560 miles (905 km) southwest of the southern tip of Baja California. Bonnie was moving toward the west at 17 m.p.h. (28 km/h). The maximum sustained wind speed was 90 m.p.h. (145 km/h) and and there were wind gusts to 105 m.p.h. (165 km/h). The minimum surface pressure was 980 mb.

Hurricane Bonnie appeared to complete an eyewall replacement cycle on Thursday. The previous small eye and eyewall was replaced by a larger eye. A circular eye with a diameter of 35 miles (55 km) was present at the center of Bonnie on Thursday night. 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 Bonnie. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The circulation around Hurricane Bonnie was still small. Winds to hurricane force extended out 25 miles (40 km) from the center of Bonnie. Winds to tropical storm force extended out 70 miles (110 km) from the center. The Hurricane Intensity Index (HII) for Hurricane Bonnie was 13.9. The Hurricane Size Index (HSI) was 6.8 and the Hurricane Wind Intensity Size Index (HWISI) was 20.7.

Hurricane Bonnie will move through an environment that will be unfavorable for intensification during the next 36 hours. Bonnie will move over water where the Sea Surface Temperatures are near 26˚C. It will move under the southern part of an upper level ridge over the Eastern North Pacific Ocean. The ridge will produce easterly winds that will blow toward the top of Bonnie’s circulation. Those winds will cause some vertical wind shear. The wind shear will inhibit intensification. Hurricane Bonnie is likely to weaken during the next 36 hours, as it moves over cooler water.

Hurricane Bonnie will move south of a high pressure system over the Eastern North Pacific Ocean. The high pressure system will steer Bonnie toward the west-northwest during the next 36 hours. On its anticipated track Hurricane Bonnie will move farther away from Baja California during the next several days.
