What this page is

Biloxi sits in Harrison County, Mississippi. This is a local briefing: it names the hazard that usually matters most here (Hurricanes), then shows the statewide ratings Mississippi homeowners use to decide what official map to open. It is not a flood-zone letter or an insurance quote.

  1. Confirm the neighborhood with a ZIP lookup.
  2. Open Hurricanes in Mississippi.
  3. Verify the address on the official maps in the sidebar, then read a matching guide.

Biloxi occupies a narrow peninsula between the Gulf of Mexico and the Back Bay, and that geography made it one of the hardest-hit cities in America when Hurricane Katrina's surge poured across the peninsula in 2005 — water rose over the beachfront highway, gutted homes and businesses, and pushed deep into neighborhoods that had never imagined flooding. The lesson is permanent: on this coast, storm surge is the hazard that defines homeownership, and hurricane season from June through November is the calendar every homeowner lives by.

The peninsula's shape leaves almost nowhere to hide from the water. Surge can attack from the Gulf side, the Back Bay side, or both at once, and Biloxi's low elevation means even a moderate hurricane can flood streets well inland of the beach. Wind compounds the damage — major storms peel roofs and blow out windows across the city — while the Back Bay's tributaries and the region's flat drainage keep low areas wet long after the storm moves on.

For homeowners, the non-negotiables start with flood insurance and a clear-eyed view of elevation: know exactly how high your home sits, and assume surge can reach higher than the last storm. Hurricane shutters or impact-rated windows, a roof in strong repair, and trimmed trees are the wind-side essentials. Keep an evacuation plan current every summer, because when a major hurricane targets the Mississippi coast, the window to leave the peninsula closes early — and the water arrives faster than most people expect.
