    Severe Winds

    Tropical cyclone winds of at least strong breeze to near gale in strength extend outward up to 440 km from the center of the typhoon. Destructive typhoon-force winds extend outward up to 90 km from the center of the typhoon.

    Rough to high seas will be experienced over the northern and eastern seaboards of Luzon (2.5 to 9.0 m). Sea travel is risky for all types of seacrafts over these waters.

    Rough to very rough seas over the western seaboards of Northern Luzon (2.8 to 4.5 m) and the northern and eastern seaboards of Northern Samar (2.5 to 4.5 m). Sea travel is risky for small seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor.

    Moderate to rough seas over the western seaboard of Central Luzon, the remaining eastern seaboard of Eastern Visayas. and the eastern seaboard of Mindanao (1.5 to 3.0 m). Mariners of small seacrafts are advised not to venture out over these waters. Inexperienced mariners of these vessels should avoid navigating in these conditions.
