TRACK AND INTENSITY OUTLOOK:
Do not focus on the center track as it may still shift within the limit of the forecast confidence cone. Heavy rainfall, severe winds, and storm surge may still be experienced far from the landfall point or center track, and even in areas outside the forecast confidence cone. Always refer to the latest hazard warnings currently in effect (e.g., Wind Signals, Heavy Rainfall Warnings, Storm Surge Warnings) and the information under “Other Hazards affecting Land Areas” of this bulletin for more details.
• On the forecast track, UWAN will emerge over the coastal waters of La Union this morning. Once over the West Philippine Sea, UWAN will maintain its strength until tomorrow (11 November) before gradually weakening due to marginally favorable environmental conditions.
• UWAN will begin to turn northwestward to northward from today until tomorrow (11 November) while remaining at typhoon category. On Wednesday (12 November), UWAN will turn northeastward towards the Taiwan Strait while weakening. It is forecast to make landfall over western Taiwan on Thursday (13 November), then rapidly weaken over the Taiwan landmass before emerging over the waters near Ryukyu Islands before weakening further into a remnant low.
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.
