Typhoon In-fa is expected to pass through the far northern CNMI somewhere between Sarigan and Maug sometime on Friday. Winds and seas will increase late Thursday ahead of the approaching typhoon, quickly exceeding hazardous levels to small craft by early Friday morning, with seas peaking at 11 to 14 feet for Tinian and Saipan, and 8 to 12 feet for Guam and Rota. Mariners are urged to take precautions and remain weather aware over the coming days.
