We improve an existing anticipatory action model for the Philippines by transforming the target variable into a high-resolution grid of 0.1 degrees, using only globally-available features, and introducing a two-stage model to focus on high-damage areas. We demonstrate that employing only the global features does not significantly influence model performance. Despite excluding local data on physical vulnerability and storm surge susceptibility, the two-stage model improves upon the municipality-based model with local features. When applied to anticipatory action, our two-stage model would show a higher True Positive rate, a lower False Negative rate, and an improved False Positive rate, implying that fewer resources would be wasted in anticipatory action.
