northwest of Agrihan, and about 270 miles north of Saipan. Storm
motion was northeast, 35 degrees, at 7 mph with maximum sustained
winds of 100 mph, becoming a Category 2 typhoon. Choi-wan is expected
to make a slight turn toward the north-northeast with a slight
increase in forward speed through Sunday, moving away from the

becoming a Category 3 typhoon tonight.

.SITUATION OVERVIEW...
Typhoon Choi-wan continues to intensify, and is expected to become a
Category 3 typhoon tonight as it continues moving away from the
Marianas and passing near Maug to the northeast. 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, TS conditions are still expected at Tinian, Saipan and
their adjacent waters in the early evening hours tonight, but then
becoming more likely to fall below TS conditions as the night goes
on.
