The National Oceanic and Atmospheric Administration is preparing to lay off more than 1,000 workers as part of the Trump administration's mandate for agencies to prepare "reductions in force," according to multiple sources familiar with the matter.

The cuts are fueling concerns that NOAA's ability to deliver lifesaving services, such as weather forecasting, storm warnings, climate monitoring and fishery oversight, will be hampered. The concerns are especially acute as hurricane and disaster season looms.
