Tropical Storm Emong (Co-may) is still moving north northeast, or away from mainland Luzon, at a very fast 40 km/h early Friday afternoon, July 25

MANILA, Philippines – Emong (Co-may) weakened further from a severe tropical storm into a tropical storm and was already passing close to Babuyan Islands, the weather bureau said early Friday afternoon, July 25.

Emong’s maximum sustained winds are down to 85 kilometers per hour from the previous 95 km/h. Its gustiness also eased to 115 km/h from 160 km/h.

At its peak, Emong was a typhoon with maximum sustained winds of 120 km/h. It made landfall twice as a typhoon — first in Agno, Pangasinan, at 10:40 pm on Thursday, July 24, then in Candon City, Ilocos Sur, at 5:10 am on Friday. It started weakening due to Northern Luzon’s mountainous terrain.

The tropical storm is still moving north northeast at a very fast 40 km/h, and may pass close to or over Batanes within the day.

The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) has removed Signal No. 3 since Emong was downgraded to a tropical storm. These are the areas remaining under tropical cyclone wind signals as of 2 pm on Friday:

Signal No. 2

  • northern part of Ilocos Norte (Dumalneg, Pagudpud, Adams, Burgos, Bangui)
  • northern part of Apayao (Calanasan, Luna, Santa Marcela)
  • Batanes
  • Babuyan Islands
  • northwestern part of mainland Cagayan (Camalaniugan, Buguey, Aparri, Allacapan, Ballesteros, Abulug, Pamplona, Claveria, Sanchez-Mira, Santa Praxedes)

The highest tropical cyclone wind signal raised due to Emong was Signal No. 4.

PAGASA maintained its rainfall outlook for Emong, previously issued at 11 am. The tropical cyclone had left floods and landslides in its wake after hitting mainland Northern Luzon.
