12W (MARING) has accelerated slightly eastward while over the North Philippine internationally named as "TRAMI" - a kind of tree in Vietnam belonging to the rose family...could become a Tropical Storm (TS) later today.

This depression will continue to enhance the Southwest Monsoon (Hanging Habagat) -- bringing cloudy conditions with occasionally slight to moderate to sometimes heavy rains and thunderstorms across the western sections of the Philippines...becoming more frequent along Western Luzon including Metro Manila today through Monday. Flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes

Meanwhile, Tropical Depression 13W has weakened into a Tropical Disturbance (LPA) as it moves closer to Southeastern China.

Residents and visitors along Taiwan and the islands of Okinawa-Ryukyu-Miyako-Yaeyama-Batanes Islands should closely monitor the development of Trami (Maring).
