Heavy Rainfall Expected the Next Few Days; Practice Caution on the Roadways

The National Weather Service (NWS) Guam Weather Forecast Office continues to monitor a weak circulation, Invest 90W, near 14 degrees north latitude and 144 degrees east longitude, as it continues to drift west of the Marianas. The system is expected to continue west of the Mariana islands, before moving northward by early next week.

Although no significant tropical development is expected, a monsoon-like pattern will continue to bring increased rain to the Marianas. Scattered to numerous showers, at times heavy, with potential thunderstorms will continue through the weekend and possibly into early next week. Rainfall amounts of 2 to 4 inches, with locally higher amounts, are likely.

Those living in flood-prone areas should clear drainage areas and unblock storm drains to minimize flooding. Residents and visitors are advised to take the following precautionary actions:
  • If driving, be alert for low visibilities and slippery roads 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 rainy conditions through this weekend, driving below the speed limit and allowing enough braking distance between vehicles.
