At 7 AM ChST, the center of Typhoon Choi-wan (26W) was located near latitude 18.4N and longitude 144.9E. This was about 235 miles north- northwest of Saipan, and about 55 miles west-southwest of Agrihan. Storm motion was north, 10 degrees, at 6 mph with maximum sustained winds of 85 mph. 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.
