In the area you have selected (Brazil) cyclone (also known as hurricane or typhoon) hazard is classified as very low according to the information that is currently available. This means that there is less than a 1% chance of potentially-damaging cyclone-strength winds in your project area in the next 10 years. Based on this information, the impact of cyclones does not necessarily need to be considered in different phases of the project, in particular during design and construction. Although the hazard is considered to be very low in the project location based on the information available in ThinkHazard!, other sources may show some level of cyclone hazard. If local or additional information sources suggest that there are cyclones, follow the recommendations below and seek expert guidance on additional recommended actions.
Climate change impact: Global average tropical cyclone wind speed and rainfall is likely to increase in the future, and the global average frequency of tropical cyclones is likely to decrease or remain unchanged. It is possible that the frequency of the most intense tropical cyclones will increase substantially in some ocean regions (IPCC, 2013). The present hazard level in areas currently affected by tropical cyclones may increase in the long-term. Projects located in such areas should be robust to future increases in cyclone hazard.
