Choi-wan is expected to make a slight turn toward the north- northeast with a slight increase in forward speed through Sunday, passing to the west of Pagan shortly. Choi-wan is forecast to intensify through tonight, becoming Category 2 as it passes Agrihan today, then Category 3 tonight as it moves away. .SITUATION OVERVIEW... Typhoon Choi-wan continues to intensify, and is expected to become a Category 2 typhoon later today as it passes to the northwest of Agrihan, with the wind field expected to expand a little more as well. As such, a Typhoon Warning remains in effect for Alamagan, Pagan and Agrihan. Due to the enhancement of the monsoon surge along the southern peripheries of Choi-wan, this is expected to continue to bring TS conditions to Tinian and Saipan the rest of today, as well as heavy downpours and strong gusts occasionally exceeding 60 mph at Guam and Rota.
