The new system will also help NOAA ready its new hurricane forecast model, the Hurricane Analysis and Forecast System (HAFS). The agency wants HAFS up and running in time for the 2023 hurricane season. The boost in computing power will help the US deliver more detailed weather forecasts further in advance, which should have economic as well as safety benefits…”
