Natural disasters such as loods, forest ires, and hurricanes can cause catastrophic damage to human life and infrastructure. We focus on response to hurricanes caused by both river water looding and storm surge. Using models for storm surge simulation and lood extent prediction, we generate forecasts about areas likely to be highly afected by the disaster. Further, we overlay the simulation results with information about traic incidents to correlate traic incidents with other data modality. We present these results in a modularized, interactive map-based visualization, which can help emergency responders to better plan and coordinate disaster response.
