The typhoon continues to have maximum winds of 205 km/h and gustiness of up to 255 km/h.

Signal No. 1 is now raised in:

Those areas under Signal No. 1 are in the regions of Cagayan Valley, the Cordillera Administrative Region (CAR), Central Luzon, Calabarzon, Bicol, and Eastern Visayas. Occasional rains with gusty winds are expected.


PAGASA warned there may be heavy to intense rain, storm surges in coastal areas, and very strong winds in Cagayan Valley and CAR beginning Friday, September 14, and in Northern Luzon on Saturday, September 15.

Ompong might make landfall in the northern tip of Cagayan on Saturday morning.

Fishermen and others with small sea vessels are advised not to venture out into the seaboards of areas under Signal No. 1, the northern seaboard of Northern Luzon, and the eastern seaboards of the Visayas and Mindanao.

Class suspensions have already been announced for the rest of the week.

The typhoon is also enhancing the southwest monsoon or hanging habagat. The enhanced southwest monsoon could trigger moderate to heavy rain in the following areas:

  • Friday – Palawan, Zamboanga Peninsula, Visayas, Metro Manila
  • Saturday – Palawan, Zamboanga Peninsula, Western Visayas, Metro Manila

Residents of areas affected by the southwest monsoon should be on alert for flash floods and landslides, too.

Ompong is the Philippines’ 15th tropical cyclone for 2018. The country usually gets an average of 20 tropical cyclones per year.

PAGASA declared the start of the rainy season last June 8.
