Natural Disaster Risk in Donner

Natural Hazard Profile: Donner, Louisiana

Located along the Gulf Coast in Terrebonne County, Donner is a small unincorporated community. The humid subtropical climate that characterizes this part of Louisiana — marked by very hot summers, mild winters, and exceptionally high humidity — directly influences the types and severity of natural hazards present, making Donner a community where hazard awareness has real practical value.

FEMA rates Donner's composite natural disaster risk at 6.6 out of 10 — high risk. Coastal flooding is the dominant hazard, with storm surge from tropical systems and nor'easters capable of inundating low-lying shoreline areas well above normal tidal levels. Residents should also account for hurricane and heat risk in their preparedness planning.

Relative to other U.S. communities, Donner's natural disaster risk is well above the U.S. national average of 4.5/10, slightly above the 6.1/10 state average. The hazard distribution here is led by coastal flood and hurricane, as measured by FEMA across Terrebonne County. While city-specific sub-county variation exists, these scores represent the best available federal risk estimate.

With a high natural disaster risk rating, Donner residents benefit from taking preparedness seriously. Reviewing insurance coverage for coastal flood and secondary hazards, registering for emergency alerts, and maintaining a household emergency kit are practical steps that can significantly reduce impact during a major event.
