...DEVELOPING TROPICAL DISTURBANCE WELL SOUTHEAST OF THE MARIANAS TO
BRING HEAVY RAIN TO THE REGION LATE THIS WEEKEND...

This Hydrologic Outlook is for Guam, Rota, Tinian and Saipan.

A loosely organized tropical disturbance is centered near a general
area well northwest of Fananu, near 11N153E. Model guidance
indicates the system will continue to trek northwestward, moving
across or east of the Marianas as it develops further.
Some uncertainty remains regarding potential rainfall impacts, but
new estimates indicate this system to bring locally heavy rainfall
of 4 to 8 inches across the region. This feature will be monitored
closely over the next several days by various agencies, so expected
rainfall totals may change. Even so, flash flooding remains likely
during the Saturday night through Tuesday time frame.

Residents in the Marianas need to closely monitor this developing
situation as watches, advisories and warnings could be issued later.

If living near streams and rivers, prepare to move items away from
stream and river banks. Make sure storm drains nearby are not
clogged, especially If living at low-lying areas.
