Hydrologic Outlook issued October 4 at 9:57PM ChST by NWS Tiyan GU Additional Details Here.

ESFGUM 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.
