菲律宾大气地球物理和天文服务管理局表示，截至5月15日，吕宋岛多个主要水库的水位持续下降。在极端高温和厄尔尼诺现象可能引发担忧的背景下，水位出现下滑。
马尼拉大都会的主要水源安格特大坝（Angat Dam）的水位从5月14日的178.85米降至5月15日的178.52米，仍低于其180米的运行水位。
伊波大坝（Ipo Dam）水位降至99.99米，拉梅萨大坝（La Mesa Dam）水位降至79.86米。吕宋岛北部和中部的多个水电大坝，包括安布考大坝（Ambuklao）、宾加大坝（Binga）、圣罗克大坝（San Roque）和潘塔邦岸大坝（Pantabangan）的水位也均有下降。
菲律宾大气地球物理和天文服务管理局将这一趋势归因于5月15日全国45个城市出现的高温指数，该指数已达到危险水平。马加特大坝（Magat）和卡利拉亚大坝（Caliraya）的水位则略有上升。
