NWS Advisories in Effect; Flash Flood Watch Canceled

The National Weather Service (NWS), Guam Weather Forecast Office continue to monitor what is now Tropical Storm Peipah (formerly 17W).

As of early this morning, Peipah was located about 385 miles north-northeast of Guam, with maximum sustained winds of 40 mph, making it a minimum tropical storm but no further intensification is expected. It is moving northwest at 17 mph and expected to pass to the far northern Marianas. The Mariana Islands, including the far northern Agrihan, Pagan, and Alamagan are not expected to experience tropical storm force winds as Peipah passes.

Guam can expect occasional rain this morning, then mostly cloudy with scattered showers and isolated thunderstorms in the afternoon and evening. The following advisories are in effect:

The flash flood watch has been canceled for Guam, Rota, Tinian, and Saipan.

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.

GHS/OCD 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.

X Flooding is a temporary overflowing of water onto land that is normally dry. Flooding may happen with only a few inches of water, or it may cover a house to the rooftop. There are many possible causes of floods including heavy rain, coastal storms and storm surge, waterway overflow from being blocked with debris, or overflow of levees, dams, or waste water systems. Flooding can occur slowly over many days or happen very quickly with little or no warning, called flash floods.
