.STORM INFORMATION...
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.
