Current Status and Outlook Tropical Disturbance (LPA) 94W (HANNA) remains quasi-stationary over the Philippine Sea during the past 12 hours as it continues to intensify slowly…likely to reach Tropical Depression (TD) classification today.  This system is forecast to remain at sea without any landfall or direct threat to the Philippines throughout its presence inside the Philippine Area of Responsibility (PAR).

LPA 94W (HANNA) together with the active Monsoon Trough will continue to enhance the Southwest Monsoon (Habagat) and bring “on-&-off” rains and thunderstorms across MiMaRoPa and the Western Sections of Luzon and Visayas today through Tuesday (Aug 06).

How strong is it? Maximum Sustained Winds (10-min avg): 40 kph near the center, with gustiness: 60 kph.
Past Movement (06 hrs) Quasi-Stationary over the Eastern Part of the Central Philippine Sea.
Forecast Highlights
  • The 5-Day Forecast (Aug 05-09) shows LPA 94W intensifying into a Tropical Depression (TD) later today, and becoming a Tropical Storm (STS) thereafter, as it tracks generally northward towards the Southern Islands of Japan, with very high uncertainty. Forecast confidence at this time remains LOW (<35% chance).
  • Likely to exit the northern border of the PAR on Friday early morning, Aug 09.
  • The presence of this potential Tropical Cyclone and the Monsoon Trough will continue to enhance the Southwest Monsoon (Habagat) and could bring occasional rains, some gusty winds and thunderstorms across MiMaRoPa and the western sections of Luzon and Visayas including Metro Manila through Tuesday (Aug 06). Please be advised that severe thunderstorms may also occur across these areas which could cause flash floods and landslides. Precautionary measures must be implemented during the occurrence of this monsoon system.
  • The next StormWatch Update will be issued after 24 hours.
