Tropical Cyclone ENAWO – Daily Update 7 March 2017 0600 UTC

The African Risk Capacity monitors tropical cyclone activity in the South-West Indian Ocean (SWIO) and relies on Africa RiskView, a disaster risk modelling platform that uses satellite-based and other geo-information to forecast wind speed and storm surge height and estimate population affected and economic loss. These modelled lesses are the underlying basis of the insurance policies issued by the ARC Insurance Company Limited, the financial affiliate of the ARC Agency, which pools risk across the continent.

Based on the forecasts presented under the previous tabs, Africa RiskView calculates the potential number of people affected by the tropical cyclone. The table below shows the number of people affected (by different categories of wind speed). It is important to note that these are forecast-based and thus subject to change as soon as the next update on the cyclone track is released:
