MANILA, Philippines - The low pressure area (LPA) off Ilocos Sur developed into a tropical depression at 2 am on Saturday, September 6.

It was given the local name Lannie, as the Philippines' 12th tropical cyclone for 2025. It is also the second tropical cyclone for September, after the short-lived Tropical Depression Kiko.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Lannie was located 315 kilometers west of Sinait, Ilocos Sur, as of 4 am.

The tropical depression is moving west over the West Philippine Sea, or away from Northern Luzon, at 15 kilometers per hour (km/h).

It has maximum sustained winds of 45 km/h and gustiness of up to 55 km/h.

Lannie is bringing moderate to heavy rain (50-100 millimeters) to Pangasinan on Saturday, with floods and landslides possible. Scattered rain and thunderstorms will also persist in the rest of the Ilocos Region, the Cordillera Administrative Region, and Cagayan Valley due to the tropical depression.

There are no tropical cyclone wind signals in effect.

Lannie is already expected to leave the Philippine Area of Responsibility (PAR) by Saturday morning or afternoon.

Outside PAR, it may strengthen into a tropical storm on Saturday evening or early Sunday morning, September 7.

Lannie is also slightly enhancing the southwest monsoon or habagat, which is still affecting Central Luzon and Southern Luzon on Saturday.

The southwest monsoon is causing scattered rain showers and thunderstorms in Central Luzon, Metro Manila, and Calabarzon, as well as isolated rain showers or thunderstorms in Mimaropa.

Zambales, in particular, is expected to have moderate to heavy rain (50-100 mm) due to the southwest monsoon on Saturday.

The southwest monsoon is also bringing strong to gale-force gusts to the Ilocos Region, Cagayan, and Isabela on Saturday and Sunday.

There were no gale warnings issued as of early Saturday morning, but PAGASA warned that conditions in certain seaboards may be dangerous for small vessels.

Up to rough seas (small vessels should not venture out to sea)
