Tropical Depression One-C formed over the Central Pacific Ocean southeast of Hawaii on Saturday night.  At 5:00 a.m. EDT on Sunday the center of Tropical Depression One-C was located at latitude 10.9°N and longitude 145.6°W which put the center about 1085 miles (1445 km) southeast of Honolulu, Hawaii.  Tropical Depression One-C was moving toward the west at 12 m.p.h. (19 km/h).  The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1005 mb.

A low pressure system over the Central Pacific Ocean southeast of Hawaii strengthened on Saturday night and the Central Pacific Hurricane Center designated the system as Tropical Depression One-C.

The circulation around Tropical Depression One-C was exhibiting more organization early on Sunday.  More thunderstorms formed near the center of the tropical depression.  Thunderstorms were also occurring in bands revolving around the center of Tropical Depression One-C.

Tropical Depression One-C will move through an environment favorable for intensification during the next 24 hours.  The tropical depression will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the southern part of an upper level ridge over the Central Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of the depression.  Those winds will cause some vertical wind shear.  The vertical wind shear will inhibit intensification, but the wind shear will probably not be enough to prevent intensification.  Tropical Depression One-C is likely to intensify to a tropical storm during the next 24 hours.

Tropical Depression One-C will move around the southern side of a high pressure system over the Central Pacific Ocean.  The high pressure system will steer the tropical depression toward the west during the next 24 hours.  On its anticipated track, the tropical depression will pass south of Hawaii early next week.
