Planalytics estimates that the potential economic impact for lost sales in the consumer and retail sector from Hurricane Irma could reach 2.75 billion US dollars.

In an update issued on the 10th of September the weather-analytics company said its estimate was in addition to the damage caused directly by the storm: “While some economic activity took place before the storm, and there will be post-storm purchasing that will occur, these ‘lost sales’ are purchases which do not occur and are not made up,” wrote Planalytics, adding: “This results in a negative impact to the economy. This estimate is based on the size and strength of the storm combined with the population under threat.”

The estimate refers to lost sales in the retail/restaurant sector and can be adjusted if the storm continues. 

As the storm passes by consumers will look for "need-based" items such as chainsaws, bagged ice, canned good, tarps, pumps, and cleaning supplies. Once businesses are able to re-open, the following retail sectors are expected to have strong and immediate increases of consumption: home centers, mass merchants, grocery stores, gas stations and convenience stores.

Shopping malls, specialty apparel stores, entertainment venues, and other businesses who are not selling need-based products will be impacted by a slower return to business as usual.
