Swiss catastrophe data company Perils has revised its loss estimate for Tropical Cyclone Debbie up to $1.66 billion from its June estimate of $1.41 billion.

In May the company estimated the insurance bill at $1.12 billion. 

Cyclone Debbie moved slowly through Queensland and NSW from March 28 until early April first as a cyclone and then as a large rain-bearing depression that caused extensive flooding.

Zurich-based Perils created the loss footprint using data collected from insurance companies in Australia and complemented this with postcode-level windspeed values from the European Centre for Medium-Range Weather Forecasts, Sydney-based Risk Frontiers and by postcode-level rain intensity measures from the Australian Bureau of Meteorology.

It is the first time that a market loss footprint from an Australian catastrophe event has been made available at a postcode level and by property line of business.

The data also differentiates the losses as “cyclone” or “flood”.

Perils’ fourth loss estimate for Cyclone Debbie is due on 28 March 2018, a year after the event.
