Reflections This 13th Anniversary of Typhoon Ondoy

As Typhoon Karding made landfall in the Philippines on September 25, 2022, it brought strong winds and torrential rain to the country, including Marikina City and nearby areas. Typhoon signal #3 was also raised in Marikina City.

Just past midnight, Marikina River's water level rose above 18 meters raising the alert level to 3rd alarm.
It reached its peak around 2:00am at 18.4 meters and slowly decreased in the next 9 hours to 15.9 meters, lowering the alert level to 1st alarm.

The typhoon somehow reminded me of Typhoon Ondoy, when waters drastically rose in the evening and all through the night. 

Coincidentally, September 26, 2022, marks the 13th anniversary of when Typhoon Ondoy hit the Philippines. During Tropical Storm Ondoy in 2009, Marikina River's water level reached an all-time high of 21.5 meters.

Even if I now live in a safe area, I still worry when there are non-stop rains and typhoons because my parent's home in SSS Village has experienced floods in the past. I know very well the feeling of anxiety while non-stop rains pour down, the sense of checking the street for floods every few minutes, the adrenalin of lifting furniture and other moving belongings to a higher place while flood water enters your house, the sense of despair when electricity goes out when you most need it, and safe guarding your house the whole night even if you're very tired and sleepy. Experiencing all this is something you'll perfect in time but hoping you won't need to experience it.

The good thing is that there were many lessons learned from Ondoy, not just from each MarikeƱo but also by local government. Thanks to the many protocols set into play plus the use of technology to assist us, it has been easier to cope with typhoon and floods.

Thanks to these online resources and public services that can greatly assist us with information and assistance we need to better prepare for not just any typhoon but also any calamity that comes our way:

Other initiatives like declogging of waterways, canals, and sewers before a typhoon hits greatly help the quick and steady flow of rainwater. 

Indeed, Marikina City has come a long way in ensuring the safety and well-being of its residents. It's reassuring that something as devastating as Typhoon Ondoy in 2009 can be prevented and not have a maximum impact as typhoons used to in the city.

Marikina River Reached Alert Level 3 On Ondoy's 13th Anniversary (September 26, 2022)

NOAH Helps You Find Areas Affected by Floods, Storm Surges in Marikina

During typhoon season, Marikina City is known to be affected by flooding due to torrential rains from both within Marikina and higher nearby areas. 

If you live in Marikina, you'll probably know which streets and barangays experience flooding. If you're unfamiliar, there is an online tool showing areas where flooding is experienced.

Thanks to the Nationwide Operational Assessment of Hazards (NOAH), they offer an online service that shows areas that are affected not only by floods but also landslides and storm surges. The website shows a map based on your location or a location you enter and will retrieve a visual representation of areas affected. The map can be zoomed in to street level or zoomed out to barangay and city level. The map is based on archived data and not a real-time source for monitoring floods. It does become a handy reference for motorists to determine what areas are prone to flooding without having to experience a real flood.


Visit https://noah.up.edu.ph to access the tool and you will be asked to input your location or any other location. You can type in an address from the street level and it will retrieve results of possible locations.


Project NOAH is still in beta release. There are ongoing developments to stabilize the platform and to complete the hazard maps
