Heavy and intense rainfall at 8 to 20 millimeters per hour is expected within the 500 km diameter of the typhoon.
Moving west northwest at 20 kph, Pagasa said Luis is likely to make landfall over the Cagayan-Isabela area on Sunday afternoon or evening and will reach Laoag City by Monday morning.
It is expected to leave the Philippine Area of Responsibility by Tuesday morning.
Public Storm Warnings remain up for the following provinces:
