The National Flood Insurance Program (NFIP) must be reauthorized and funded before the October 1 start of the new fiscal year (FY).
If Congress does not reauthorize and fund the NFIP by October 1 (whether in a continuing resolution or in a FY 2024 appropriations bill), the agency would not be able to issue new flood insurance policies. Plus, funding would become even more of an issue than it already is. (FEMA, the Federal Emergency Management Agency, is already running low on funds with literally billions in claims from various natural disasters still outstanding.)
