Hurricane-Ready: 5 Flood Response Essentials Every Emergency Manager Needs This Season

Hurricane Helene was catastrophic and caused an estimated $30.5 billion to $47.5 billion in damages. What you may not realize is that up to 86% of this damage ($26 - $41 billion)1 was caused by flooding, including coastal storm surge, riverine flooding, and flash flooding from intense rainfall.

As hurricane season intensifies, so does the pressure on emergency managers to stay ahead of destructive storms. Coastal and inland communities alike are facing increased flood risks due to recurring severe weather events, aging infrastructure, and complex logistics. 

This year, agencies are stepping up with modern tools and advanced strategies. Below, we break down the top 5 actions emergency managers are taking to get hurricane-ready, and how live and predictive flood intelligence supports each step. 

1. Identify At-Risk Areas with Predictive Flood Modeling 

Knowing where flooding is most likely to occur is the first step toward effective preparation. With FloodMapp ForeCast, agencies can visualize street-level flood impacts 72 hours before the event starts. 

ForeCast helps you: 

• Pinpoint flood-prone roads, neighborhoods, and critical infrastructure 

• Disseminate targeted alerts and warnings 

• Prioritize evacuation planning 

• Protect sites and mitigate flood damage to assets 

• Allocate response resources more efficiently

2. Plan and Communicate Evacuation Routes 

Once you know where the water is going, the next step is routing people and crews safely during the flood event. NowCast to help you: 

• Identify flood-safe routes for emergency responders 

• Gather and maintain dynamic situational awareness on impacted roadways 

• Send localized and personalized alerts to communities at risk

3. Position Response Resources Strategically 

Strategic staging of personnel and supplies can make or break a response effort. With hourly updates from NowCast, your field crews and swift-water teams stay informed about:
