On 17 November 2024, Super Typhoon Man-yi (local name: Pepito) hit the northern part of the Philippines with maximum sustained winds of 195 km/h and lowest central pressure of 920 hPa. Man-yi was the third typhoon to make landfall in the Philippines for that month. Man-yi first passed through the island province of Catanduanes before proceeding north and making landfall at Dipaculao in Aurora province. High-risk storm surge warnings were issued in the country with an estimated height of 2.1 to 3.0 meters at the coast of Aurora for a 48-hour lead time forecast. Although extensive documentation on the damages and affected families was done by government agencies, there were no official storm surge measurements known to be reported. Thus, there is a need to investigate the empirical gap on storm surge levels that occurred in Dipaculao and correlate them with the observed damage to structures. A field survey was conducted at Dipaculao and was able to measure storm surge heights of up to 5.52 meters. A drone was deployed to assess the structural and non-structural damage due to severe wind and storm surge in the area. The field survey observations were supplemented with a numerical simulation of the wind field from Man-yi using  the Weather Research and Forecasting (WRF) model. Detailed observations of the damages to a hotel around 20 meters from the coast were documented, and lessons learned from the event are discussed.
