BASED on information received from the National Weather Service in Tiyan, Guam and compiled at the CNMI Emergency Operations Center-State Warning Point, a flood watch remains in effect through Thursday afternoon.
Flash flooding caused by excessive rainfall continues to be possible on Saipan, Tinian and Rota through Thursday afternoon.
Excessive runoff may result in flooding of rivers, streams, and other low-lying and flood-prone locations. Streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Extensive street flooding and flooding of creeks and rivers are possible. The highest likelihood for flooding is for Guam and Rota. Mudslides are also a distinct possibility for central and southern Guam.
Tropical Storm Mawar continues to approach the Marianas. As the storm gets closer, showers are expected to increase significantly. Latest model guidance shows rainfall potential in excess of 15 inches, with locally heavier amounts possible. This would result in extensive flooding across the islands.
Governor Arnold I. Palacios is advising the residents of Saipan, Tinian, and Rota to monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. If living near streams and rivers, prepare to move items away from stream and river banks. Make sure storm drains nearby are not clogged, especially in low-lying areas.
