TRACK AND INTENSITY OUTLOOK
• It must be emphasized that heavy rainfall and severe winds may still be experienced in localities outside the landfall point and the forecast confidence cone. Refer to “Other Hazards affecting Land Areas” for more details. Furthermore, the track may still shift within the limit of the forecast confidence cone.
• WILMA is forecast to move west southwestward until tomorrow (06 December) before turning generally westward for the remaining forecast period. On the forecast track, the center of WILMA may make its initial landfall or pass close over Eastern Visayas or Dinagat Islands between this evening and tomorrow morning. Afterwards, it will continue to traverse Visayas until Sunday (07 December). It will then emerge over Sulu Sea and may pass over northern Palawan by Monday (08 December) morning.
• WILMA will slightly intensify before landfall but will likely remain as a tropical depression throughout the forecast period. Further intensification is possible 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. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
