Tropical Depression Querubin maintained its strength over the waters east of Mindanao as Signal No. 1 remained up in Davao Oriental, PAGASA said.

In its 5 a.m. bulletin, the state weather bureau warned the interaction between Querubin and the shear line will potentially bring heavy or intense rainfall in the Visayas and Mindanao.

Querubin is moving north northwestward at 10 kilometers per hour with a maximum sustained winds of 45 km/h near the center and gustiness of up to 55 km/h.

Querubin is seen to move north northeastward or northward over the waters east of Mindanao within the next 24 hours. During the same period, it will also weaken into a remnant low pressure area.

On Thursday through Sunday, the remnant low pressure area of Querubin will traverse Mindanao, Sulu Sea, and Palawan.

"Although a weakening scenario is expected, possible re-development into a tropical depression may occur once the remnant low of Querubin reaches the West Philippine Sea," PAGASA said.
