Before the emergency — maps, tools, and the honest picture of what Delaware throws at different parts of the state.
See DE hazardsDE hazard profile
Delaware's low elevation and Delaware Bay position make it highly vulnerable to hurricane storm surge. Sandy (2012) caused $76M in damage across the state, flooded coastal communities, and caused significant damage to the Rehoboth and Lewes areas. A direct major hurricane hit on the Delaware coast would push surge far inland across the flat topography. Delaware's Atlantic and Delaware Bay coastlines face regular nor'easter flooding. The Rehoboth, Bethany Beach, and Fenwick Island resort communities flood with every significant nor'easter. Tidal flooding in Lewes and New Castle is increasingly frequent as sea levels rise — some areas now flood during routine high tides without storms. The Christina, Brandywine, and Red Clay rivers flood the Wilmington metro regularly. The March 2011 flooding caused $30M in damage across northern Delaware. Heavy rain events saturate Delaware's flat terrain quickly — drainage is slow and flooding can persist for days. Agricultural flooding in Sussex County is increasingly common.
Direct landfalls and tropical moisture bring catastrophic wind, surge, and inland flooding.

Insurance gaps
Standard homeowner's policies in Delaware exclude flood damage. Flood insurance through the NFIP has a 30-day waiting period — it cannot be purchased when a storm is forecast. Check your declarations page annually to confirm your coverage limits and deductibles.
Not in your standard policy
Flood damage — requires NFIP or private flood policy
Earthquake damage — requires separate endorsement
Sewer & drain backup — requires endorsement ($50–$100/yr)
Landslide / mudflow — generally excluded
