MANILA — Typhoon Egay rapidly intensified as it moved over the Philippine Sea on Monday morning, the state weather bureau said, as it raised storm warning signals over more areas in Luzon and Visayas.

Egay was last spotted 525 kilometers east of Baler, Aurora, packing maximum sustained winds of 150 kilometers per hour near the center and 185 kph gusts, PAGASA said in its 11 a.m. bulletin.

The typhoon may enhance the southwest monsoon or habagat, which will bring occasional to monsoon rains over the western portions of Central Luzon, Southern Luzon, and Visayas in the next three days, PAGASA warned.

Egay could further strengthen into a super typhoon on Tuesday or Wednesday. It may directly hit or come close to the Batanes-Babuyan area, PAGASA weather specialist Obet Badrina said.

"Posible po na yung track nitong bagyo ay pumunta pa or mag-southward pa, mas lumapit sa kalupaan," he said.

"Kaya po itong area nitong Cagayan Valley, partikular na yung probinsya ng Cagayan, gayundin sa Apayao at sa Ilocos Norte, kailangan po talagang mag-ingat at maghanda yung mga kababayan natin d’yan dahil bukas ng gabi hanggang afternoon o tanghali ng Miyerkoles pinakamararanasan yung impact nitong bagyong Egay."

(The typhoon could go further south. This is why residents in Cagayan Valley, particularly in Cagayan, as well as those in Apayao and Ilocos Norte should prepare because Egay's impact would be most felt from Tuesday night until Wednesday afternoon.)
