Type Hydrologic Outlook

Issuing Time Wed, 04 Mar 2026 15:52:00 PST

Brief Description Hydrologic Outlook
Detailed Description ESFGUM This Hydrologic Outlook is for Guam, Rota, Tinian, and Saipan. Confidence continues to grow regarding heavy rainfall potential sometime this weekend and continuing into the first part of next week. Currently, a broad and weak circulation is in the initial stages of formation southwest of Chuuk/southeast of Polowat, and northwest of Kapingamarangi. This disturbance will slowly head west-northwest towards the Marianas the next several days. As it does so, locally heavy rainfall may develop, with gusty winds also possible with the heavier showers or thunderstorms that develop. At this time, model guidance indicates at least medium confidence for 5 to 10 inches of rainfall, with locally higher amounts possible. Due to antecedent rainfall of over 4 inches in some locations earlier this week, the potential for flash flooding and mudslides is higher than normal. As we approach this event, if forecast confidence continues to increase, a Flash Flood Watch may need to be issued with later forecasts. Timing: Late Friday through early to middle of next week. Confidence for timing is medium. Location: All of the Marianas Impacts: Widespread rainfall will develop, some of it will be locally heavy. Current estimates show 5 to 10 inches of rainfall may occur, with locally heavier amounts possible. Residents of the Marianas should continue to monitor current forecasts at www.weather.gov/gum.
