As of 10 am, Lannie was over the coastal waters of Maasin City, Southern Leyte, heading for the Camotes Sea, which is between Eastern Visayas and Central Visayas.

The tropical depression accelerated a bit, moving west northwest at 20 kilometers per hour from the previous 15 km/h.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) also said Lannie still has maximum sustained winds of 45 km/h and gustiness of up to 55 km/h. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

PAGASA added that “the enhanced easterly flow north of the tropical depression may also bring occasional gusts” to extreme Northern Luzon and the coastal and mountainous areas of the eastern part of Luzon on Monday.

Lannie is also causing moderate to rough seas in the Philippines’ coastal waters on Monday, especially in areas under Signal No. 1. Travel is risky for small vessels.

PAGASA expects Lannie to move over the Visayas until Monday evening or early Tuesday morning, October 5, then emerge over the Sulu Sea and cross the Cuyo archipelago.

The tropical depression could make another landfall in the northern part of Palawan or Calamian Islands on Tuesday morning before exiting landmass toward the West Philippine Sea within a couple of hours.

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

The weather bureau also said Lannie is likely 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 early Wednesday morning, October 6, over the West Philippine Sea.

Lannie may leave the Philippine Area of Responsibility (PAR) on Thursday morning.

Outside PAR, it is seen to head for the southern part of China, and may be upgraded into a severe tropical storm by Saturday morning, October 9.

It is also the first tropical cyclone for the month of October, coming right in the middle of the filing of certificates of candidacy for the 2022 elections, which is taking place across the country. The filing of COCs is until Friday, October 8.

An average of 20 tropical cyclones form within or enter PAR each year. (READ: LIST: PAGASA’s names for tropical cyclones in 2021)
