Typhoon In-fa will approach the far northern CNMI late Friday and into the weekend. Winds and seas will sharply increase starting early Friday ahead of the approaching typhoon, quickly exceeding hazardous levels to small craft early on Friday. Seas of 10 to 15 feet are expected to develop in the coastal of Tinian and Saipan. Although, sustained winds are not expected to reach tropical-storm force at this time, tropical-storm force gusts are possible. Mariners are urged to remain weather aware over the coming days.
