Where is NWS predominantly found?

The correct answer is North America, as the National Weather Service (NWS) is a part of the United States federal government that provides weather, water, and climate data, forecasts, and warnings. It focuses primarily on the United States, including territories and coastal waters. The NWS is responsible for providing life-saving information related to severe weather events within North America, making it a crucial agency for emergency preparedness and response in this region.

The other options represent regions where other meteorological services may operate, but they do not specifically pertain to the NWS, which is firmly established in North America. Therefore, while the NWS may collaborate or have similar agencies in other regions, its primary focus and operations are centered in North America.
