TRACK AND INTENSITY OUTLOOK • WILMA is forecast to move west southwestward until Saturday (06 December) before turning generally westward for the remaining of the forecast period. On the forecast track, the center of WILMA may make its initial landfall Eastern Visayas or Dinagat Islands between tomorrow (05 December) evening and Saturday morning. Afterwards, it will continue to traverse Visayas until next week, Monday (08 December). It will then emerge over Sulu Sea and may pass over northern Palawan between Monday evening and Tuesday (09 December) morning. • WILMA will slightly intensify before landfall but will likely remain a tropical depression throughout the forecast period. Further intensification is likely once it emerges over the West Philippine Sea. Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials.
