The National Oceanic and Atmospheric Administration (NOAA) is a federal agency focused on the condition of the oceans and the atmosphere. It plays several distinct roles within the Department of Commerce. With the mission to protect life and property, and enhance the economy, NOAA's National Weather Service is the sole official voice of the U.S. Government for issuing warnings during life-threatening weather situations. NOAA's National Ocean Service provides products, services and information that promote safe navigation, support coastal communities, sustain marine ecosystems, and mitigate coastal hazards.
