The acronym NWS is most famously recognized as the National Weather Service, the U.S. government agency that delivers daily weather forecasts, advisories, watches, and warnings to the public. In the business world, it serves as the Nasdaq ticker symbol for News Corp (and its predecessor), refers to Hong Kong's NWS Holdings, and even marks the Nintendo World Store in New York City. Geographically and strategically, NWS covers the North Warning System, a chain of Arctic radar stations, and the North West Shelf Project, a major natural gas extraction venture in Australia. In science, it denotes the New World screwworm, a parasitic blowfly with flesh-eating maggots, as well as the Northwest Semitic branch of the Afro-Asiatic language family. Additionally, NWS can stand for Nuclear Weapons States (under the Non-Proliferation Treaty), the North Wilkesboro Speedway, or an Adelaide-based Australian TV station owned by the Nine Network.
