Tropical Storm TRAMI (MARING) has started moving north-northeast slowly during the past 6 hours...gaining strength over the warm waters of the North Philippine Sea.

This storm will continue to induce the Southwest Monsoon (Hanging Habagat) - bringing cloudy and windy conditions with "on-and-off" slight to moderate to sometimes heavy rains across the western sections of the Philippines...becoming more frequent with moderate-to-heavy monsoon rains along MiMaRoPa, the National Capital Region (Metro Manila), Ilocos Region, Cordillera Administrative Region, and CaLaBaRZon tonight through Wednesday. Flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes

Meanwhile, Typhoon PEWA (01C) upgraded from Tropical Storm (TS) has maintained its northwesterly movement across the open seas of the Western Pacific Ocean. Latest dynamic forecast models continues to show the system moving generally northwestward and may affect Wake Island on Wednesday. Its center was located about 1,285 km southeast of Wake Island or 5,715 km east of the Philippines (14.3N Lat 177.5E Lon)...with maximum winds of 120 km/hr near the center...moving NW @ 15 kph towards Wake Island Area. This storm is too far away to affect any part of the Philippines.

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