Small Craft Advisory in Effect

The National Weather Service (NWS) Guam Weather Forecast Office issued a small craft advisory, in effect for the coastal waters of Guam, Rota, Tinian, and Saipan until 6 a.m. Sunday.

Southwest winds of 15 to 20 knots, with gusts up to 30 knots, and seas of 6 to 8 feet are expected. Heavy showers and thunderstorms could also lead to choppy seas, gusty winds, and frequent lightning strikes.

Inexperienced mariners, especially those operating smaller vessels, should avoid boating in hazardous conditions.

Through today and tomorrow, it is expected to be cloudy with numerous showers and isolated thunderstorms. Locally heavy showers remain possible.

Residents and visitors are advised to take the following precautionary actions:

  •   Be aware of your surroundings and do not drive on flooded roads.
  •   If driving, be alert for low visibilities in heavy rain;
  •   Slow down where water is ponding on the road;
  •  Turn Around, Don’t Drown. Avoid walking or driving through flood waters. Just 6 inches of moving water can knock you down, and 2 feet of water can sweep your vehicle away;
  •  Do not camp, park, or hike along streams and rivers. These areas can flood quickly and with little warning.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to practice caution while traveling in heavy rain, driving below the speed limit and allowing enough braking distance between vehicles.
