Hurricane & Storm Risk in Biloxi

Hurricane Katrina, August 29, 2005: The Storm That Defines Current Memory

Hurricane Katrina made landfall on the Mississippi-Louisiana border on August 29, 2005, and drove a storm surge exceeding 26 feet directly into Biloxi and Gulfport -- among the highest storm surges ever recorded on the U.S. coastline. Nearby Pass Christian recorded 27.8 feet of surge, and a 28-foot storm tide was measured at the Hancock County Emergency Operations Center. In Biloxi specifically, the surge didn't just flood buildings -- it physically tore at least three floating barge casinos from their moorings and deposited their hulls up to 200 yards inland, destroyed the Treasure Bay casino outright (a loss exceeding $100 million), blew out the first and second floors of the Beau Rivage, and damaged the Tivoli Hotel so severely when a drifting casino barge struck it that the building was demolished the following year. All 13 hotel-casinos then operating on the Mississippi coast were damaged or destroyed.

Katrina killed 53 people in Biloxi and destroyed an estimated 20% of the city -- part of a storm that killed 238 people across Mississippi and nearly 1,400 people across the wider Gulf Coast region. Twenty years on, regional retrospective coverage has described a genuinely two-track recovery: East Biloxi's casino district rebuilt into a larger, more resilient land-based gaming economy than existed before the storm, while parts of the city's historic Main Street commercial corridor have recovered much more slowly -- a real, documented unevenness in how the recovery actually played out on the ground, not a uniform story of full restoration.

Hurricane Camille, August 17, 1969: The Prior Record-Holder

Before Katrina, Hurricane Camille held the U.S. storm-surge record for this stretch of coast. Camille made landfall near Bay St. Louis, Mississippi -- roughly 25 miles west of Biloxi -- at 11:30 p.m. on August 17, 1969, as a Category 5 hurricane with sustained winds approaching 175 mph, driving a storm surge of 24.6 feet at Pass Christian. The storm's most infamous, tragic episode occurred at the Richelieu Apartments in Pass Christian, where roughly two dozen residents chose to stay through the storm rather than evacuate; the building collapsed under the surge, and most of those who remained drowned.

Camille remains, alongside Katrina, one of the two benchmark storms that define this coast's storm history for anyone who has lived here more than a few decades -- a genuine reminder that catastrophic storm-surge events on this specific stretch of the Mississippi coast are a repeated pattern across generations, not a single historical anomaly.

Hurricane Elena (1985) and Hurricane Georges (1998): Two More Direct Hits

Hurricane Elena came ashore near Biloxi on September 2, 1985 as a Category 3 storm with winds of 115 mph. Elena's erratic track -- it reversed course multiple times before finally making landfall -- triggered what was, at the time, described as the largest peacetime evacuation in U.S. history along the northern Gulf coast, and caused roughly $1.3 billion in damage and 9 deaths regionally.

Hurricane Georges made landfall near Biloxi on September 28, 1998 as a Category 2 storm with winds up to 110 mph, driving a storm surge of up to 8.9 feet in Biloxi specifically. Neither Elena nor Georges approached Katrina's or Camille's catastrophic scale, but both were direct hits on Biloxi within recent living memory, and both are part of the honest, documented pattern of this coast absorbing a major hurricane roughly once a decade or more often, not once a generation.

More Recent Storms: Zeta (2020) and Ida (2021)

Hurricane Zeta made landfall in Louisiana in late October 2020 as a Category 3 storm with peak winds of 115 mph, with meaningful impacts across the Mississippi coast as well; this page did not independently confirm Biloxi-specific damage figures from Zeta. Hurricane Ida made landfall in Louisiana on August 29, 2021 -- sixteen years to the day after Katrina -- as a Category 4 storm with winds of 150 mph and caused an estimated $75.3 billion in damage regionally, though Ida's most severe impacts were concentrated west of Biloxi in Louisiana; this page did not independently confirm a Biloxi-specific damage total from Ida either. Both storms are included here as evidence of continued, active hurricane activity affecting this general stretch of the northern Gulf coast in the past several years, not as confirmed direct-impact events on Biloxi specifically.

Evacuation: Zones A, B, and C, and a Land Route Off the Peninsula

Harrison County uses a three-tier evacuation zone system -- Zones A, B, and C -- developed in coordination with local, state, and federal agencies and updated in 2024 to reflect current storm-surge and flood-vulnerability modeling. Unlike a ferry-dependent barrier island, Biloxi's peninsula connects to the mainland by road, meaning evacuation happens by car rather than by a capacity-limited ferry schedule -- a real structural advantage. It does not mean evacuation is instant or optional: Harrison County has issued mandatory evacuation orders for its most exposed zones ahead of major storms, and the Coast Transit Authority provides registered transportation to inland shelters for residents needing assistance (registration at coasttransit.com or (228) 896-8080). Harrison County's Emergency Management Agency can be reached directly at (228) 865-4002 for current zone status and evacuation planning.

Bridge capacity is also a real practical consideration specific to Biloxi: the Biloxi Bay Bridge (U.S. 90) connects Biloxi to Ocean Springs, and Biloxi is not evacuating in isolation -- Gulfport, Ocean Springs, and other Harrison and Jackson County communities are typically moving on the same regional road network at the same time during a mass evacuation.

A Real, Verified Sign of Post-Katrina Engineering Seriousness

One genuinely reassuring, independently confirmed fact about how this region responded to its worst storm damage: the Biloxi Bay Bridge, destroyed by Katrina's 22-foot storm surge and 100 mph gusts in 2005, was rebuilt under a $339 million design-build contract explicitly engineered to withstand a Category 5 hurricane, with 95 feet of vertical clearance over the shipping channel -- a dramatically higher standard than the 1962 original it replaced, which had roughly 21 feet of clearance and was destroyed by a storm that, at landfall in Mississippi, was officially only a Category 3. The new bridge reopened November 1, 2007, about a month and a half ahead of its contracted schedule. That's a real, verifiable data point about the seriousness of post-Katrina infrastructure engineering standards in this specific region, even though it says nothing directly about any individual home's construction quality.

What This Means for a Buyer

Biloxi's hurricane history is genuinely more severe, and more repeated, than most of the coastal markets profiled on this site -- Katrina (2005) and Camille (1969) are both benchmark, catastrophic-scale storms for this exact stretch of coast, and Elena (1985) and Georges (1998) add two more confirmed direct hits within the past four decades. That history should inform serious, real budgeting for windstorm and flood insurance (covered in depth on this site's Coastal Insurance and Flood Zones pages) and a genuine evacuation plan, not an assumption that Katrina was a once-in-history outlier that won't recur in a buyer's ownership horizon.

It should also be read alongside the real, verified fact that this region's major post-Katrina infrastructure -- the Biloxi Bay Bridge chief among it -- was rebuilt to a materially higher engineering standard than what existed before 2005. Ask a Biloxi-focused buyer's agent and a licensed contractor or engineer about a specific property's construction date and wind/flood mitigation features relative to current code, since a home built or substantially rebuilt after Katrina is likely to reflect meaningfully different, more storm-resilient standards than one that predates it.
