ESFGUM

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

Invest 96W is still a broad, disorganized disturbance located about
300 miles north of Kosrae. Ensemble model guidance continues to show
a passage anywhere between south of Guam to north of Saipan as a
tropical storm or typhoon. Uncertainty is still high regarding
timing, location, and intensity, but the potential for locally heavy
rainfall and flooding continues to increase approaching this weekend.

This is expected to produce 5 to 8 inches of rainfall between
Saturday and Monday, with localized amounts up to 12 inches possible.

As showers are likely to persist, consistent rainfall is likely to
saturate the soils enough to increase chance for mudslides.

Residents on these islands need to closely monitor this developing
situation as flood watches, advisories and flash flood warnings could
be issued later this weekend.

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.
