Tropical Storm Hone formed east-southeast of Hawaii on Thursday afternoon.  At 5:00 p.m. EDT on Thursday the center of Tropical Storm Hone was located at latitude 15.9°N and longitude 142.2°W which put the center about 885 miles (1430 km) east-southeast of Hilo, Hawaii.  Hone was moving toward the west-northwest at 14 m.p.h. (22 km/h).  The maximum sustained wind speed was 40 m.p.h. (65 km/h) and there were wind gusts to 50 m.p.h. (80 km/h).  The minimum surface pressure was 1005 mb.

A low pressure system over the Central Pacific Ocean east-southeast of Hawaii strengthened on Thursday afternoon and the U.S. Central Pacific Hurricane Center designated the system as Tropical Storm Hone.  More thunderstorms developed near the center of Hone’s circulation on Thursday afternoon.  More thunderstorms also formed in bands revolving around the center of Tropical Storm Hone.  Storms near the center of Hone began to generate upper level divergence that pumped mass away from the tropical storm.

The circulation around Tropical Storm Hone was small.  Winds to tropical storm force extended out 20 miles in the northern side of Hone’s circulation.  The winds in the southern part of Tropical Storm Hone were blowing at less than tropical storm force.

Tropical Storm Hone will move through an environment favorable for intensification during the next 24 hours.  Hone will move over water where the Sea Surface Temperatures are near 27°C.  It will move under the southern part of an upper level ridge over the Eastern North Pacific and the Central Pacific.  The upper level ridge will produce northeasterly winds that will blow toward the top of Hone’s circulation.  Those winds will cause some vertical wind shear, but the wind shear will not be enough to prevent intensification.  Tropical Storm Hone is likely to intensify gradually during the next 24 hours.

Tropical Storm Hone will move around the southern side of a subtropical high pressure system over the Eastern North Pacific and Central Pacific.  The high pressure system will steer Hone toward the west-northwest during the next 24 hours.  On its anticipated track, Tropical Storm Hone will move closer to Hawaii.  Hone could be southeast of Hawaii by Saturday evening.
