President Ferdinand "Bongbong" Marcos Jr. said Tuesday flooding in Las Piñas City was no longer as severe as before, citing the government's ongoing dredging and drainage-clearing efforts.

In an ambush interview during his visit to the area, Marcos said the effects of the continuous rains in the city showed that the measures being implemented by the government were having an effect.

However, he acknowledged that more work needs to be done to fully address flooding.

"Mukhang nagkaroon naman ng epekto. Hindi gan'un kalala ang pagbaha. Medyo nabawasan. Dati hanggang sa dibdib pa abot, ngayon wala pa, hindi pa, hanggang kulang pa sa tuhod ang baha," Marcos said.
