The Navotas-Malabon river remains "calm" as of Sunday afternoon despite the incessant rains brought by Typhoon "Rolly" to the National Capital Region.
According to the local government of Navotas City, the water level in the river "is not yet high" and the speed of the wind is normal.
Meanwhile, residents living in flood-prone areas of barangays Navotas East, Navotas West, Sipac, Tangos, and Tanza 1 and 2 were already evacuated at the city's elementary schools, according to Irish Cubillan, head of the city's public information office.
There are still no flooded areas, she added, as the city's pumping stations with 57 "bombastik units" continue their operations.
"Close monitoring in District 2 and North Bay Boulevard North and South, Navotas West, Navotas East, Sipac-Almacen, but all barangays have been advised to proceed with preemptive evacuation," she added.
There are also no flooded areas in Malabon City, according to its public information office head, Bong Padua.
"Ambon lang ang nararanasan namin ngayon (It only drizzles)," he said.
