Hurricane Dora passed south of Hawaii on Tuesday. At 11:00 p.m. EDT on Tuesday the center of Hurricane Dora was located at latitude 11.4°N and longitude 160.1°W which put it about 700 miles (1125 km) south-southwest of Honolulu, Hawaii. Dora was moving toward the west at 23 m.p.h. (37 km/h). The maximum sustained wind speed was 130 m.p.h. (210 km/h) and there were wind gusts to 155 m.p.h. (250 km/h). The minimum surface pressure was 953 mb.

Hurricane Dora changed very little on Tuesday. The structure of Dora continued to be very symmetrical. An eye with a diameter of 12 miles (19 km) was still at the center of Hurricane Dora. 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 Dora’s circulation. Storms near the core generated upper level divergence that pumped mass away from the hurricane.

The size of the circulation around Hurricane Dora did not change much on Tuesday either. Winds to hurricane force extended out 30 miles (50 km) from the center of Dora’s circulation. Winds to tropical storm force extended out 115 miles (185 km) from the center of circulation. The Hurricane Intensity Index (HII) was 25.1. The Hurricane Size Index (HSI) was 9.9 and the Hurricane Wind Intensity Size Index (HWISI) was 35.0.

Hurricane Dora will move through an environment that will be favorable for a major hurricane during the next 24 hours. Dora will move over water where the Sea Surface Temperatures are near 27°C. It will move through a region where the upper level winds are weak and there will be little vertical wind shear. Hurricane Dora has been in equilibrium with its environment during the past 24 hours. The intensity of Dora may not change much during the next 24 hours. Since the circulation around Hurricane Dora is so small, any changes in the environment will have large effects on the intensity of Dora.

Hurricane Dora will move south of a subtropical high pressure system over the North Pacific Ocean. The high pressure system will steer Dora toward the west during the next 24 hours. On its anticipated track, Hurricane Dora will be near Johnston Island on Thursday.
