MANILA, Philipines – All alerts have been lifted on Marikina river before noon Friday, as the river's water level dipped due to improved weather.
The city's public information office, in its Twitter account, said the river's water level was at 14.8 meters above sea level as of 11:55 a.m. This means that the first alarm is effectively lifted.
The first alarm on the river is raised once it breaches the 15-meter mark. With this alarm, residents are warned and advised to monitor the situation.
Second and third alarms, meanwhile, are raised when the river's water level reaches 16 and 17 meters, respectively.
Under second alarm, people are advised to prepare for evacuation. The third alarm means residents must evacuate on its own.
The fourth alarm, the critical level, is raised when the water breaches the 18-meter mark. Forced evacuation is enforced at this point.
Marikina's water level rose to as high as 21.5 meters above sea level on Tuesday at the height of heavy monsoon rains, forcing thousands of Marikina residents to flee their homes.
Due to the improved weather since Thursday afternoon, Marikina authorities are now allowing evacuees in the city to go back to their homes as floods subsided in most parts of the city.
Before dawn Thursday, residents in low-lying areas were told to evacuate after the river's water level rose to as high as 20.6 meters above sea level. But a few hours later, the water level was reported to have gone down.
Some residents chose to remain inside evacuation centers as flood waters in their area have yet to fully subside.
