La Mesa dam overflows again

MANILA (Updated 2:02 a.m.) -- The La Mesa Dam in Quezon City overflowed anew Monday night, following continuous heavy rains over Metro Manila.

Also, the weather bureau has raised red warning signal over the National Capital Region late Monday night due to continues rains.

At 10 p.m. Monday, the water level at La Mesa Dam was at 80.23 meter, which is already above its spilling level of 80.15 meters.

This is the second time the La Mesa Dam overflowed in the last 24 hours. The dam also reached spilling level at 2 a.m. Monday.

Water that flows down the spillway goes to the Tullahan River and empties into Manila Bay.

It is expected to cause floods in Greater Fairview, North Fairview, Novaliches, and Gulod, San Bartolome, Sta. Monica, and Sta. Lucia up to Valenzuela and Malabon where the Tullahan River passes, dam official George Lantin said.

Meanwhile, flood monitoring at the Marikina River reached second alarm Monday night after the Sto. Niño station water level measurement reached 16.01 meters.

The heavy downpour triggered floods in parts of Metro Manila, according to the Metropolitan Manila Development Authority (MMDA).

The heavy rains are caused by the shallow low pressure area and the southwest monsoon affecting Luzon and the Visayas, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said.

In its twitter account, Pagasa said heavy and intense rains were observed over the metropolis with an accumulated rainfall of 83.5 mm was recorded in Quezon City and 63.5mm over Marikina in the past three hours, while the rest of Metro Manila also experienced heavy to intense rainfall of 10.0 to 30.0 mm/hr.

The weather bureau expects the heavy rains to continue throughout the night.

Pagasa also warned of flooding in low-lying areas and those located near the river channels.

"Residents in high risk areas are advised to take precautionary measures, monitor the weather condition, and watch out for the next warning," it said.

Meanwhile, the MMDA said on its twitter account, as of 9 p.m., Maysilo Circle in Mandaluyong was unpassable to cars and light vehicles due to the waist-deep floods. Traffic was also at a stand-still in Coastal Road, Valenzuela Exit to Camachile in Quezon City and San Mateo, Rizal.
