The system is moving\ntoward the west near 10 mph (17 km/h), and a turn toward the \nwest-northwest is expected on Thursday.  On the forecast track, the \ncenter will be nearing the Hawaiian Islands by late Friday.\n \nRecent satellite wind data indicate that maximum sustained winds \nare near 40 mph (65 km/h) with higher gusts. However, the system \nstill lacks sufficient organized shower and thunderstorm activity \nto be considered a tropical storm. The disturbance is forecast to \nbecome a tropical storm by Thursday night, and additional \nstrengthening is forecast thereafter.\n* Formation chance through 48 hours...high...90 percent.\n* Formation chance through 7 days...high...90 percent.\n \nTropical-storm-force winds extend outward up to 275 miles (445 km)\nmainly to the northeast of the center.\n \nThe estimated minimum central pressure is 1002 mb (29.59 inches).\n \n \nHAZARDS AFFECTING LAND\n----------------------\nKey messages for Potential Tropical Cyclone One-C can be found in\nthe Tropical Cyclone Discussion under AWIPS header HFOTCPCP2 and\nWMO header WTPA42 PHFO.\n \nWIND:  There is an increasing risk of wind impacts in the Hawaiian\nIslands regardless of the exact track of this system.\n \nRAINFALL: The Potential Tropical Cyclone is expected to produce \nrainfall totals of 5 to 10 inches across much of the Island chain, \nwith maximum totals of 20 inches possible. This rainfall may produce \nlife-threatening flooding and mudslides, especially in areas of \nsteep terrain.\n \nSURF:  Swells generated by the disturbance are expected to reach\nthe east-facing shores of the state on Friday, spreading westward\nand building through the weekend. These swells are likely to cause\nlife-threatening surf and rip current conditions.
