Shortly after its landfall, my colleague, Ben Brookes, and I drew attention in the RMS live Harvey updates to the fact that the storm was “not a wind event.” Like Sandy, flood losses, we wrote, would quickly overtake wind losses.
We recalled how Dr. Robert Muir-Wood had insisted back in February 2014 that “water is the new wind.” Those with exposure in harm’s way, he argued, needed to “get to grips with the details of modeling and managing hurricane-driven flood risk.”
It was unsurprising, then, to hear Robert on BBC World News last week describing Hurricane Harvey’s destruction as absolutely avoidable. Yes, Harvey is an extreme event. There were, however, historical precedents for stalling rain storms — and there are clear business cases for investing in resilience before extreme events, rather than just responding after.
