If you don’t know what HPC is, it’s the NWS center that provides forecasts for accumulating precipitation and extreme temperature events. It provides an incredibly useful set of map and text products that communicate the risk of heavy rain, ice and snow as well as excessive heat and cold from the short-term up to about 8 days into the future.

“The new name captures the breadth of products and services produced by the center,” the NWS said in a public statement. “There has been broad support for the name change by center employees, users of the center’s products and services, the employees’ organization, NOAA leadership, the academic community, the private sector, and other stakeholders.”
