Brief Description Hydrologic Outlook
Detailed Description ESFGUM This Hydrologic Outlook is for Guam, Rota, Tinian and Saipan. A tropical disturbance could bring heavy rain to the Marianas from Thursday evening through Sunday. Latest model guidance shows a surface trough within Chuuk State that is expected to move northwest over the next couple of days. This trough is expected to develop into a weak circulation Thursday or Friday near the Marianas. Models differ on location and strength of this circulation, however, they do agree that heavy rainfall is likely as early as Thursday, but most likely Friday through the weekend. There is a potential for Guam and the CNMI to see rainfall amounts varying from 5 to 10 inches by Sunday, though locally heavier amounts are possible. This rainfall is expected to produce minor flooding across the islands, with flash flooding possible in the areas of heavier rainfall. 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.
