The National Oceanic and Atmospheric Administration (abbreviated as NOAA / ˈ n oʊ. ə / NOH-ə) is an American scientific and regulatory agency charged with forecasting weather, monitoring oceanic and atmospheric conditions, charting the seas, conducting deep-sea exploration, and managing fishing and protection of marine mammals and endangered species in the US exclusive economic zone.
A tropical wave in the eastern Atlantic has a 20 percent chance for developing over the next seven days. National Hurricane Center tracking Tropical Storm Don. New tropical wave appears on map
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean.
Significant wave height H 1/3, or H s or H sig, as determined in the time domain, directly from the time series of the surface elevation, is defined as the average height of that one-third of the N measured waves having the greatest heights: [5] / = = where H m represents the individual wave heights, sorted into descending order of height as m increases from 1 to N.
The height of the wave was reported to be abnormally high with respect to the sea state at the time of the incident. [58] In March 2014, a massive wave struck Roi-Namur in Kwajalein Atoll in the Marshall Islands on an otherwise calm, sunny day, penetrating well inland, flooding parts of the island and swamping coastal roads.

Within the United States National Weather Service (NWS), forecast weather maps began to be published by offices in New York City, San Francisco, and Honolulu for public use. North Atlantic forecasts were shifted from a closed United States Navy endeavor to a National Weather Service product suite via radiofacsimile in 1971, while northeast ...
In 1970, NOAA was formed and the NOAA Data Buoy Office (NDBO) was created within the National Ocean Service (NOS) and located in Mississippi. In 1982, the NDBO was renamed NDBC and was placed under NOAA's NWS. The first buoys deployed by NDBC were the large 12-m discus hulls constructed of steel.
NOAA ship Delaware II in foul weather on Georges Bank. Sea State 5 and 8 range. In oceanography, sea state is the general condition of the free surface on a large body of water—with respect to wind waves and swell—at a certain location and moment. A sea state is characterized by statistics, including the wave height, period, and spectrum ...
