<p>CEBU CITY — The sight of several houses being washed away by the current in Butuanon River in Mandaue City last Sept. 9 was one never seen before by people who happened to pass by the area at the time.</p><p>It left passersby either stunned or scared, especially as some of them personally know some residents in that part of Barangay Casuntingan.</p><p>“I was more than scared because some of my friends lived there, so I was worried too,” said tricycle driver Felix Lansang, who witnessed and recorded on video the tragedy that was caused by torrential rains.</p><p>The swelling of the Butuanon River that day displaced more than 400 families, or over 1,800 people, according to local authorities.</p><ul class="op-related-articles">	<li><a href="https://news.abs-cbn.com/news/09/10/22/more-than-1800-flee-homes-as-flash-floods-hit-cebu">More than 1,800 people flee homes as flash floods hit Cebu</a></li>	<li><a href="https://news.abs-cbn.com/news/09/13/22/mandaue-city-placed-under-state-of-calamity-after-flood">Mandaue City placed under state of calamity after flood</a></li></ul><div> </div><p>It also caused flooding in the main highways, impeding traffic to the dismay of hundreds of motorists and commuters.</p><p>While some residents have returned to their homes as water level subsided, others remain in evacuation centers, waiting for funds to rebuild their houses.</p><div><strong>AMOUNT OF RAINFALL</strong></div><p>Based on PAGASA Mactan’s radar, the average rainfall in Cebu during severe thunderstorms reaches up to 100mm, equivalent to over 500,000 barrels of water, even without the presence of a typhoon.</p><p>“It is normal heavy rainfall, especially when it is the rainy season of La Niña.
