Ada intensifies into tropical storm east of Surigao City

MANILA, Philippines – Ada strengthened from a tropical depression into a tropical storm at 2 pm on Thursday, January 15, while remaining over the Philippine Sea.

It was assigned the international name Nokaen, a name contributed by Laos which refers to a kind of bird.

In a briefing past 5 pm on Thursday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Ada now has maximum sustained winds of 65 kilometers per hour from the previous 55 km/h. Its gustiness is now up to 80 km/h from 70 km/h.

The tropical storm was last spotted 400 kilometers east of Surigao City, Surigao del Norte, as of 4 pm. It slightly accelerated, moving northwest at 15 km/h from 10 km/h.

Ada is projected to pass close to Eastern Samar and Northern Samar by Saturday, January 17, and Catanduanes by Sunday, January 18.

But PAGASA said that “a further westward shift” in Ada’s track may lead to landfall in Eastern Visayas and/or Bicol. “The track forecast may change in succeeding bulletins, especially for the Saturday or Sunday period,” added the weather bureau.

Significant rain from Ada is still expected in Caraga, Eastern Visayas, and Bicol over the next three days, with floods and landslides likely.
