It was spotted at 215 kilometers northwest of Basco, Batanes as of 4 p.m. Sunday .
Storm signal number 1 is now hoisted over Batanes, Ilocos Norte, and northwestern Cagayan, including the Babuyan Group of Islands.

"Inaasahan nating hihina ang epekto ng habagat sa ating bansa, dahil kung saan pupunta si Huaning, susunod 'yung habagat," PAGASA weather forecaster Aldczar Aurelio said.
