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.
• LUIS will move generally northwestward and may make landfall or pass close to Northern Luzon tonight or tomorrow (04 August) early morning. Afterwards, it will sharply turn east northeastward while moving away from the Philippine landmass. The forecast track is highly uncertain and may change in the succeeding bulletins.
• LUIS is forecast to remain as a tropical depression over majority of the forecast period and may be downgraded into a remnant low by Wednesday (05 August) before becoming fully assimilated into the circulation of Tropical Cyclone DOLPHIN.
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.
