If water rises
The first hour matters most. Do these in order.
Last updated November 5, 2026
- Call 911 if anyone is in danger.
- Leave early rather than late. Don't wait for water on the road.
- Never drive through water on Milton Road. It's deeper and faster than it looks.
- Check your evacuation zone on Genasys Protect (protect.genasys.com).
- Move people, pets and medicines first. Things can wait.
- Text the neighbor group so others know where you are and what you see.
