.STORM INFORMATION...
At 3 AM ChST, the center of Tropical Storm 26W was located near
latitude 16.1N, longitude 150.5E. This was about 325 miles east-
northeast of Saipan, 325 miles east-southeast of Alamagan, and
420 miles east-northeast of Guam. Storm motion was west-
northwest, 285 degrees, at 5 mph. Storm intensity was 40 mph. The
current forecast track reflects an intensifying 26W will move
into the CNMI on Friday, curving north-northeast as it nears
Alamagan Friday night as a Category 1 typhoon, then pass near
Pagan and east of Agrihan Saturday.

.SITUATION OVERVIEW...
Tropical Storm 26W has slowed down, and the latest forecast track
no longer reflects a full passage moving to the west of the
islands. 26W will continue west through Thursday night, making a
turn to the northwest Friday morning as it begins to approach
Alamagan from the south, turning sharply northward, then north-
northeastward late Friday night, which will bring it near Pagan
and east of Agrihan through Saturday. This sharper northward turn
will pull the tropical storm force wind field slightly further
north, with the latest forecast still including Saipan and
northern parts of Tinian briefly within the southern edge of the
TS winds. This forecasted passage over Alamagan and Pagan will
prolong the duration of damaging winds across the northern
islands, likely leading to a lengthy period of time of damaging to
destructive tropical storm conditions beginning Thursday evening
and continuing into Sunday afternoon. 26W is forecast to
strengthen to a typhoon Friday morning as it approaches Alamagan,
which would bring Alamagan, and later Pagan, directly within the
typhoon force winds Friday night through early Saturday morning.
So, a Typhoon Watch has been issued for Alamagan and Pagan, and a
Tropical Storm Warning has been issued for Alamagan and Pagan.
