A more thorough explanation:

NWS

NWS stands for National Weather Service, which is a part of the National Oceanic and Atmospheric Administration (NOAA). The NWS provides weather forecasts, warnings, and other weather-related information to the public.

• The NWS issued a tornado warning for our area.
• I checked the NWS website to see if it was going to rain today.

These examples illustrate how the NWS provides important information to help people prepare for and stay safe during severe weather events. By issuing warnings and providing forecasts, the NWS helps people make informed decisions about their plans and activities.
