Typhoon In-fa is expected to pass through the far northern CNMI somewhere between just north of Saipan to as far north as Maug island sometime on Friday. Winds and seas will increase late Thursday ahead of the approaching typhoon, potentially exceeding hazardous levels to small craft by Friday morning, with seas peaking at 8 to 12 feet. Mariners are urged to take precautions and remain weather aware over the coming days.
