National Weather Service

Overview

The National Weather Service (NWS) is the United States federal agency that issues the nation’s official weather warnings — the only body in the country empowered to do so in life-threatening weather, in its own description (NOAA). Part of the National Oceanic and Atmospheric Administration (NOAA) inside the Department of Commerce, it runs 122 local Weather Forecast Offices, 13 River Forecast Centers, and nine national prediction centers, and traces its founding to February 9, 1870 (NOAA; NOAA Climate.gov). After losing roughly one in seven employees in 2025, it is rebuilding staff and reorganizing while its director warns of a bumpy budget ahead (E&E News by POLITICO).

Beyond the org chart, the NWS is simultaneously forecaster, warning system, and keeper of the nation’s severe-weather memory: its local offices maintain the event records by which historic outbreaks like the 1955 Blackwell tornado are still measured (National Weather Service, Norman forecast office).

From Signal Service to the National Weather Service

The agency began as a military project. On February 9, 1870, President Ulysses S. Grant signed a joint resolution of Congress authorizing the Secretary of War to establish a government weather service, assigned to the U.S. Army Signal Service under Brigadier General Albert J. Myer as the Division of Telegrams and Reports for the Benefit of Commerce (NOAA). Its first job was warning mariners on the Great Lakes and the coasts of approaching storms, and the network grew from 24 stations in 1870 to 284 by 1878, building on an earlier volunteer network organized by Joseph Henry of the Smithsonian Institution (NOAA Climate.gov; NOAA).

The service’s first encounter with tornado forecasting was a false start. Lieutenant John Finley of the Signal Corps issued routine tornado forecasts for 18 regions in 1884, but in 1887 General William B. Hazen ordered tornado forecasting terminated, believing “the harm done by such a prediction would eventually be greater than that which results from the tornado itself” (NOAA). In 1891 the service became a civilian agency, the U.S. Weather Bureau, under the Department of Agriculture, and in 1940 it moved to the Department of Commerce (NOAA). The modern era began by accident in 1948: after a tornado struck Tinker Air Force Base on March 20, Air Force forecasters Ernest J. Fawbush and Robert C. Miller issued the nation’s first tornado forecast five days later, and it verified when a second tornado struck the same base (NOAA). Public demand led the Weather Bureau to create a Severe Local Storms unit in 1952, which issued its first public tornado forecast that March (NOAA).

The vocabulary the public now takes for granted dates to a disaster. During the 1965 Palm Sunday outbreak, a double-funnel tornado near Dunlap, Indiana, killed 266 people despite generally accurate forecasts, because the public did not understand the Bureau’s capability (NOAA). Afterward the Bureau replaced “tornado forecast” with “tornado watch,” standardized watch areas, and made the outlook a public product — a “watch” meaning severe weather is possible in the next few hours, a “warning” meaning it has been observed or is expected soon (NOAA). In 1970 the Weather Bureau was renamed the National Weather Service and placed under the newly created NOAA, still within the Department of Commerce (NOAA).

How the warning machine works

Headquarters in Silver Spring, Maryland, sets policy and coordinates programs, while six regional headquarters — Eastern, Southern, Central, Western, Alaska, and Pacific — manage operations in their territories (National Weather Service). That regional structure, in place for about 50 years, is being replaced in 2026 by seven sectors, with administrative functions moving to national headquarters (E&E News by POLITICO). At the sharp end are 122 Weather Forecast Offices, each issuing advisories, warnings, and short-term forecasts for its county warning area around the clock — including aviation and river forecasts, balloon launches for upper-air data, and NOAA Weather Radio broadcasts (National Weather Service; NOAA Climate.gov).

Above the local offices sit the national centers. The nine National Centers for Environmental Prediction include the Aviation Weather Center, the Climate Prediction Center, the National Hurricane Center (NHC), the Storm Prediction Center (SPC), the Space Weather Prediction Center, the Weather Prediction Center, the Ocean Prediction Center, the Environmental Modeling Center, and NCEP Central Operations — the starting point, the agency says, for nearly all U.S. weather forecasts (National Weather Service). The NHC, part of the NWS within NOAA, forecasts tropical cyclones in the Atlantic and the Central and Eastern Pacific, issuing hurricane watches 48 hours ahead of tropical-storm-force winds and warnings 36 hours ahead (Congressional Research Service). Thirteen River Forecast Centers watch the nation’s waterways for flooding, and 21 Center Weather Service Units — 84 meteorologists embedded in air route traffic control centers — serve the Federal Aviation Administration (National Weather Service).

The record-keeper: damage surveys and the 1955 outbreak

The NWS also writes the official history of American weather disasters: its local offices maintain event pages reconstructing outbreaks from damage surveys, radar records, and contemporary accounts. The clearest example is the Great Plains tornado outbreak of May 25–26, 1955, as recorded by the NWS forecast office in Norman, Oklahoma. On the evening of May 25, a tornado touched down about 8 miles west of Marland around 9:00 PM CDT, moved north through Blackwell, and dissipated in Kansas (National Weather Service, Norman forecast office). It struck Blackwell at 9:27 PM CDT, killing 19 people in town and one more northeast of it, and damaging or destroying approximately 80 blocks (National Weather Service, Norman forecast office). A second tornado developed near Peckham, moved into Kansas, and killed 80 people in and near Udall; both tornadoes were rated F5 (National Weather Service, Norman forecast office). The same record preserves the Blackwell Journal-Tribune’s building-by-building survey — about 85 structures damaged but occupied, about 70 extensively damaged but repairable, about 190 completely destroyed — and notes the destruction of two major Blackwell industries, the Hazel Atlas Glass Company plant and the Acme Foundry (National Weather Service, Norman forecast office). The 1955 Blackwell tornado and the 1955 Udall tornado remain paired in that record as the two F5s of one outbreak night, part of the wider Great Plains tornado outbreak of May 1955 (National Weather Service, Norman forecast office).

The 1955 record shows how far warning tools have come: then, no Doppler radar, no computer model guidance, no satellite data. During the NWS’s $4.5 billion modernization of the 1990s, the WSR-88D (NEXRAD) Doppler radar network was deployed nationwide, and a study in the American Meteorological Society’s journal Weather and Forecasting found that the share of tornadoes receiving warnings nearly doubled, from 35% before installation to 60% after, while mean warning lead time rose from 5.3 to 9.5 minutes and expected fatalities fell 45% (ScienceDaily). The implication is direct: the radar network is the single most consequential life-saving investment in the agency’s history, and its benefits show up as minutes of warning, not just better forecasts. The same record-keeping habit extends backward to 1948: the Norman office’s table still lists the March 20 tornado’s $10.25 million damage and the March 25 tornado’s $6.1 million (National Weather Service, Norman forecast office).

An agency under strain: 2025–2026

The NWS entered 2025 already about 200 people below ideal staffing, then lost nearly 600 workers — roughly one in seven — through firings of probationary employees, buyouts, retirements, and resignations (The Washington Post, via The Japan News). Staffers worked double shifts, adjacent offices covered understaffed regions under a “buddy system,” outreach was jettisoned, and two offices — one in California’s Central Valley, one in western Kansas — could no longer operate around the clock (The Washington Post, via The Japan News). Many offices cut back twice-daily weather-balloon launches, a key source of upper-air data for forecast models (E&E News by POLITICO).

The rebuild is underway but incomplete. The agency won authorization to hire 450 employees, had brought aboard about 274 by mid-2026, and still stood more than 300 short of its early-2025 staffing (E&E News by POLITICO). In January 2026, Director Ken Graham told a town hall at the American Meteorological Society’s annual conference that the agency did not have the money to do everything and that some services would be cut back (E&E News by POLITICO). The six-region-to-seven-sector reorganization, a revived plan to embed meteorologists in emergency operations centers, and the unresolved question of whether reduced balloon launches degraded forecast skill make the NWS a live test of rebuilding a warning system mid-crisis (E&E News by POLITICO). Congress rejected many of the funding cuts the White House requested, but hiring alone cannot quickly replace decades of experience lost to early retirements (E&E News by POLITICO).

Frequently asked questions

What does the National Weather Service do? The NWS provides weather, hydrologic, and climate forecasts and warnings for the United States, its territories, and adjacent waters, to protect life and property and support the national economy (NOAA). Its local offices issue the watches, warnings, and short-term forecasts the public acts on, while its national centers handle hurricanes, severe storms, and aviation and ocean hazards (National Weather Service).

Is the National Weather Service part of NOAA? Yes. The NWS is an agency within NOAA, which sits inside the U.S. Department of Commerce (NOAA). NOAA is the parent science agency; the NWS is its weather-forecasting and warning arm. Its director is Ken Graham today (National Weather Service).

What is the difference between a tornado watch and a tornado warning? A watch means severe weather is possible during the next few hours; a warning means severe weather has been observed or is expected soon (NOAA). The “watch” terminology replaced “tornado forecast” after the 1965 Palm Sunday outbreak, when forecasters realized the public did not understand the old wording.

Which NWS center forecasts hurricanes? The National Hurricane Center, part of the NWS within NOAA, forecasts tropical cyclones in the Atlantic and the Central and Eastern Pacific (Congressional Research Service). It issues hurricane watches 48 hours ahead of tropical-storm-force winds and warnings 36 hours ahead, coordinating with local forecast offices and FEMA.

What happened to NWS staffing in 2025? About 600 employees — roughly one in seven — left through firings, buyouts, retirements, and resignations, leaving some offices unable to operate around the clock (The Washington Post, via The Japan News). The agency has since been authorized to hire 450 people but remained more than 300 short of early-2025 staffing by mid-2026 (E&E News by POLITICO).

What this profile does not claim

This profile does not state the NWS’s current budget or exact current headcount, because no fully-read source verified them. It does not claim the 2025 cuts caused any specific forecast failure, and NOAA disputes that balloon-launch changes degraded its models. It reports the Blackwell/Udall casualty figures as the NWS Norman office’s record — 19 killed in Blackwell plus one northeast of town, 80 in and near Udall — and does not resolve the small baseline differences in reported pre-2025 headcount. It covers only the United States agency: it is not NOAA itself, not the National Hurricane Center (one of its component centers), and not any other country’s national weather service. And it does not treat the agency’s “sole official voice” phrasing as an independent finding; that is the NWS’s own description of its role.
