The National Weather Service (NWS) Guam Weather Forecast Office issued a small stream flood advisory, in effect for Guam until 7:15 p.m. Heavy rain will cause urban and small stream flooding. Up to one inch of rain has already fallen. Additional rainfall of up to two inches is expected.
Some locations that will experience flooding include Dededo, Tamuning, Yigo, Mangilao, Chalan Pago-Ordot, Barrigada, Yona, Agana Heights, Andersen AFB, Talofofo, Mongmong-Toto-Maite, Sinajana, Inarajan, Asan, Merizo, Piti, Santa Rita, and Umatac.
Excessive rainfall will cause localized flooding in low-lying and poor drainage areas, and rapidly rising streams and rivers. Those living in flood-prone areas should take action; clear drainage areas and unblock clogged storm drains in your area to minimize flooding. Take action if flood advisories are issued. Do not camp, park, or hike along streams, rivers, and creeks during heavy rainfall. These areas can flood quickly and with little warning.
A marine weather statement has been issued. A line of heavy showers is producing winds to around 30 knots. Mariners can expect gusty winds, locally higher waves, and lighting strikes. Boaters should seek safe harbor immediately until this storm passes.
The community is reminded to practice caution on the roadways, driving below the speed limit and allowing enough braking distance between vehicles. Avoided flooded roads.
