Online Resources: Typhoon Yolanda

For updates on Typhoon Yolanda visit the feature page on the Official Gazette website. The page contains a Google Crisis Map in partnership with Google Philippines, including a cowdsourced map of evacuation centers, crisis areas, and relief drop zone areas in relation to Typhoon Haiyan/Yolanda. PCDSPO is working with Google to ensure Philippine government data is provided in a timely manner.

Unified Hashtags:


#rescuePh  for those needing rescue. This hashtag will be monitored by volunteers who will consolidate reports; the consolidated reports are submitted by PCDSPO to NDRRMC.
#reliefPH for aid and relief efforts. This hashtag will be monitored by DSWD.
#floodsPH to report floods to media, fellow citizens, and the authorities.

How to make sense of flood alerts:


Under the heavy rainfall warning system, a yellow warning is raised when the expected rainfall amount is between 7.5 mm to 15 mm within one hour and likely to continue.

Communities given this advisory are advised to be aware of the weather condition and warned that flooding may be possible in low-lying areas.

The orange alert is raised in areas where rainfall is between 15 mm to 30 mm within one hour. Flooding is a definite threat in communities under the green alert.

A red alert is issued when downpours constitute an emergency. This is raised when observed rainfall is more than 30 mm within one hour or if rainfall has continued for the past three hours and is more than 65 mm.

When Pagasa raises a Red warning, communities should be prepared to respond. It means serious flooding is seen and that residents should be ready to evacuate to safety.

How it works:

Based on the alert level, find out if your area is affected. For example, if you live in Marikina, go to Project Noah. The real time flood reference for Marikina can be seen if you click flood maps and go to flood inundation. PAGASA generate flood scenario for Marikina river every 10 min.

In cases of alerts, it’s the LGU in charge:

MMDA Flood Control – 882-4177, 882-0925
Parañaque DPOS – 829-2056

Pasig Traffic – 643-0000, 724-5813

Makati Public Safety Dept – 844-3146, 819-3270
