A flash flood watch is in effect on Saipan, Tinian, and Rota through this evening.
Also, a high surf advisory is now in effect in east and south facing reefs of the Marianas until 10am Wednesday morning.
A small craft advisory in effect until 10am Wednesday.
Based on information received from the National Weather Service in Guam and compiled at the CNMI Emergency Operations Center-State Warning Point, the flash flood watch is in effect for a portion of the Marianas, including Rota, Tinian, and Saipan through Tuesday evening.
Heavy showers and thunderstorms associated with Tropical Depression 06W will affect the islands beginning last tonight and increase through this morning. Torrential rains could lead to flash flooding in low-lying and poor-drainage areas.
Rainfall of 3 to 5 inches with locally heavier amounts are possible through this evening.
A flash flood watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. Residents are being advised that flash flooding can become life-threatening very quickly. Monitor conditions in your area and the latest forecasts and be prepared to take action if flash flood warnings are issued.
The high surf from the tropical disturbance will create dangerous swimming and surfing conditions and localized beach erosion.
Tropical Depression 06W will pass near Guam today. Its approach and passage will cause surf to quickly build to hazardous levels overnight. Once 06W has moved west of the islands into the Philippine Sea Tuesday afternoon, surf will quickly subside.
Beachgoers and mariners are advised to continue to exercise precautionary measures when entering the water. Inexperienced swimmers should remain out of the water due to dangerous surf conditions.
Strongest winds and highest seas are expected Tuesday before gradually subsiding tonight. Strong winds and hazardous seas could capsize or damage vessels. Mariners should consider altering plans to avoid possible hazardous conditions. Remain in port, seek safe harbor, alter course, and/or secure the vessel for severe wind and seas. (Saipan Tribune)
