Issued: 12:00 NN PhT (04:00 GMT) Monday 19 August 2013
Next Update: 6:00 PM PhT (10:00 GMT) Monday 19 August 2013

Tropical Storm TRAMI (MARING) continues to intensify while drifting very slowly over the North Philippine Sea...could threaten Taiwan and the island group of Miyako and Yaeyama beginning Tuesday.

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) and CaLaBaRZon today through Tuesday. Flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes

Meanwhile, Tropical Storm PEWA (01C) has slowed its northwesterly movement as it intensifies over the far Western Pacific Ocean. Latest dynamic forecast models continues to show the system moving across the open seas of the Western Pacific Ocean and may affect Wake Island on Wednesday. Its center was located about 1,380 km southeast of Wake Island or 5,795 km east of the Philippines (13.6N Lat 178.1E Lon)...with maximum winds of 110 km/hr near the center...moving NW @ 11 kph towards Wake Island Area. This storm is too far 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).

TS Trami (Maring) is expected to move slowly northward for the next 24 hours...turning northwest to west-northwest by 48 hours. On the forecast track, the core of Trami (Maring) will remain over the warm open waters of the North Philippine Sea, just to the south of Okinawa on Tuesday morning...and will be in the vicinity of Yaeyama-Ishigakijima-Miyako Islands before noontime Wednesday.

Trami (Maring) is expected to continue gaining strength within the next 24 to 48 hours...and could become a Typhoon on Tuesday evening. Advance Intensity Forecast (AIF) shows Trami (Maring) reaching its maximum sustained winds of 130 km/hr on Wednesday morning.
