Surigae is forecast to gradually accelerate while moving west-northwestward until Sunday, April 18, and then turn northward by Monday, April 19, according to PAGASA.
It is forecast to enter the Philippine Area of Responsibility (PAR) between tonight and tomorrow morning (LT).
The storm is forecast to reach typhoon category in the next 36 hours and may continuously intensify.
The domestic name "Bising" will be assigned to this tropical cyclone once inside the PAR.
The public and disaster risk reduction and management offices in the Philippines, especially those situated over the eastern portions of Southern Luzon and the Visayas, are advised to continuously monitor for updates on this tropical cyclone.
Considering the uncertainty in the track forecast of this tropical cyclone, a westward shift in the current forecast track may result in potentially significant impacts over the aforementioned areas over the weekend (April 17 - 18) and into Monday.
The international name Surigae was contributed by the Democratic People’s Republic of Korea (North Korea) which means a kind of eagle.
