Hydrologic Outlook

ESFGUM

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

A potential tropical disturbance will likely develop in the area and bring periods of heavy rainfall to the Marianas with rainfall totals of 4 to 7 inches possible.

Heavy showers will moisten soils throughout the event and increase potential for mudslides.

Residents on the Marianas need to closely monitor this developing situation as flood watches, advisories and flash flood 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.
