Nottinghamshire County Council has been told it will receive less than half the amount of extra grit it ordered from the government.
Earlier this week, the authority said it had used more than three-quarters of its initial stock of 14,600 tonnes.
To help it cope with the ongoing cold weather, it asked for 5,000 tonnes from a newly-released stockpile, but has now revealed it will get just 2,300 tonnes.
The council said it would be enough to last until an order from Peru arrived.
About 6,000 tonnes of grit is being sent from the South American country, and is due to arrive early next year.
In the meantime, the authority said it was continuing to grit all A and B roads and bus routes.
