Continental United States (CONUS) hurricane-related inflation-adjusted damage has increased significantly since 1900. However, since 1900 neither observed CONUS landfalling  hurricane frequency nor intensity show significant trends, including the devastating 2017 season.

Two large-scale climate modes that have been noted in prior research to significantly impact CONUS landfalling hurricane activity are El Niño-Southern Oscillation on interannual timescales and the Atlantic Multi-decadal Oscillation on multi-decadal timescales. La Niña seasons tend to be characterized by more CONUS hurricane landfalls than do El Niño seasons, and positive Atlantic Multi-decadal Oscillation phases tend to have more CONUS hurricane landfalls than do negative phases.
