The National Weather Service (NWS), Guam Weather Forecast Office continues to monitor what is now Tropical Storm Peipah (formerly 17W), located approximately 385 miles north-northeast of Guam.
Forecasters do not expect the tropical storm to intensify and the Mariana Islands are not expected to experience any tropical storm force winds when Peipah passes.
Today's forecast calls for occasional rain this morning, then mostly cloudy with scattered showers and isolated thunderstorms in the afternoon and evening.
The flash flood watch has been canceled for Guam, Rota, Tinian, and Saipan but several advisories remain in effect:
A high surf advisory remains in effect for Guam, Rota, Tinian, and Saipan through Tuesday night, meaning high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous conditions for swimmers and beach goers. Hazardous surf of 10 and 12 feet along west facing reefs and 8 to 10 feet along south facing reefs is expected.
A high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through Tuesday night. Rip currents are powerful channels of water flowing quickly away from shore. Dangerous rip currents are expected along south and west facing reefs. If caught in a rip current, yell for help. Remain calm and stay afloat while waiting for help. If swimming out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current. Rip currents are life threatening.
A small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 p.m. this evening. West winds of 15 to 25 knots with, gusts to 30 knots, and combined seas of 9 to 12 feet will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
Guam Homeland Security/Office of Civil Defense remind residents and visitors to continue to practice caution on wet roadways, driving below the speed limit and allowing enough braking distance between vehicles. Avoid floodwaters and use alternate routes if flooding is encountered.
