The National Weather Service (NWS) Guam Weather Forecast Office provided a hydrologic outlook for Guam. NWS advised a robust upper-level low will interact with a series of trade-wind troughs, bringing showers and thunderstorms to the region this week.
Occasional heavy showers are expected to begin as early as Monday and continuing through most of the week. NWS advised latest model guidance indicates rainfall amounts ranging from 2.5 inches to over 6 inches are possible during the week, with the heaviest rainfall likely Tuesday through Thursday.
Localized flooding will be possible in low-lying and poor drainage areas. Residents and visitors are advised to take precautionary actions now by clearing drainage areas and unblocking clogged storm drains in your area to minimize the chance of flooding.
The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to be alert for additional advisories from NWS.
