Tropical cyclones are extremely powerful weather hazards.
Study the table below, which shows the peak sustained wind speeds (in miles per hour, mph) for a selection of tropical cyclones in the North Atlantic basin during 2022 and 2023.
| Tropical cyclone | Year | Peak sustained wind speed (mph) |
|---|---|---|
| Fiona | 2022 | 130 |
| Ian | 2022 | 150 |
| Nicole | 2022 | 75 |
| Idalia | 2023 | 115 |
| Lee | 2023 | 160 |
| Margot | 2023 | 90 |
