Gov. Jennifer Granholm says state parks could close, and Detroit casinos and liquor sales could take a hit if she has to shut down the government on Monday.
She says processing motor vehicle titles and other services also could be affected if lawmakers don't reach a deal solving the state's budget deficit by tomorrow.
State programs that protect citizens' health and safety, such as state police patrols, could continue.
Today's announcement is Granholm's first public statement on what services may be shut down and which will be kept open if a shutdown occurs.
The Democratic governor, Democrat-controlled House and Republican-controlled Senate have failed to agree on how to erase a projected $1.75 billion deficit in the state budget for the fiscal year that starts Monday.
The Legislature adjourned Wednesday night but closed door meetings and negotiations continued among state leaders.
