Issued at: 1:00 PM PhT (05:00 GMT) Saturday 06 December 2014
Next Update: Saturday Evening, 06 December 2014

HAGUPIT (RUBY) has weakened anew into a Typhoon classification as it continues to move closer to Samar in a slow pace endangering Eastern Visayas and Southern Bicol area. The potential landfall area of this cyclone is along the northern part of Eastern Samar between 10PM-12MN tonight.

This typhoon will continue to enhance the Northeast Monsoon (Hanging Amihan) - bringing mostly cloudy and windy conditions and cooler temperatures across Northern and Central Luzon...becoming more frequent with possible occasional slight to moderate rains along eastern sections of Cagayan, Isabela, Aurora, and Northern Quezon. The threat of flash floods and landslides are likely in hazard-prone areas especially along river banks and mountain slopes of the affected areas. Residents are advised to take necessary precautions.

Residents and visitors along Southern Luzon, Visayas and Northeastern Mindanao should closely monitor the development of Hagupit (Ruby).
