Hundreds of National Oceanic and Atmospheric Administration and National Weather Service employees were laid off Thursday in the latest round of federal workforce cuts under President Donald Trump’s administration.

The layoffs were confirmed in a statement from California U.S. Rep. Jared Huffman, a Democrat, and reported by Axios and The Hill.

Staff members who answered the phone Thursday afternoon at the National Weather Service’s Boulder, Pueblo and Grand Junction offices referred questions to the NOAA’s national office.

In an email, NOAA spokesperson Susan Buchanan said the agency will not discuss internal personnel matters and remains dedicated to its mission.

Huffman, a member of the U.S. House Natural Resources Committee, condemned the firings as a move that will bring “vital programs to a screeching halt.”
