H.R. 4866 would authorize appropriations for federal agencies to develop and improve fire weather forecasts, establish committees to research wildfires, and develop recommendations for disseminating fire warnings. CBO assumes that the bill will be enacted near the middle of calendar year 2024 and that the authorized and estimated amounts will be appropriated for each year. In total, CBO estimates that implementing the bill would cost $32 million over the 2024-2029 period; any spending would be subject to the availability of appropriated funds.
