Next Update: 6:30 PM PhT (10:30 GMT) Sunday 03 August 2014

The strong typhoon (Halong) which has been moving slowly westward over the waters west of Guam has rapidly intensified into a Super Typhoon as it entered the Philippine Area of Responsibility (PAR)...and is now over the easternmost part of the Philippine Sea. The howler is now locally named "JOSE."

This intense typhoon will enhance the Southwest Monsoon (Habagat) and bring occasional to frequent rains, and thunderstorms with gusty winds (not exceeding 70 kph) across Western Visayas, MiMaRoPa, CaLaBaRZon, and some portions of Western and Central Luzon including Metro Manila through Tuesday.
The threat of flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes of the affected areas during the occurrence of severe thunderstorms. Residents are advised to take necessary precautions.

Residents and visitors along Taiwan, Okinawa and Ryukyu Islands, and Southern Japan should closely monitor the development of STY Halong (Jose).
