In the next 24 hours or until Tuesday, Lannie will continue to cause moderate to rough seas in the Philippines’ coastal waters, especially in areas under Signal No. 1. Travel is risky for small vessels.

Lannie is expected to keep moving over the Visayas until Monday evening, before emerging over the Sulu Sea and crossing the Cuyo archipelago.

The tropical depression might make its final landfall in the northern part of Palawan or Calamian Islands on Tuesday morning, then exit landmass toward the West Philippine Sea within a couple of hours.

From late Tuesday to early Thursday morning, October 7, Lannie will be moving over the West Philippine Sea.

Lannie is projected to stay a tropical depression while crossing land, though it may slightly intensify once over the Sulu Sea or the West Philippine Sea. It could strengthen into a tropical storm by Tuesday evening or early Wednesday morning, October 6.

Lannie may leave the Philippine Area of Responsibility (PAR) on Thursday morning, then head for the southern part of China.

PAGASA added that Lannie will continue intensifying outside PAR. It may reach severe tropical storm status by Friday, October 8.
