Refuse collections across most of Ceredigion have been suspended because of the weather conditions.
Ceredigion council said waste would not be collected for the rest of the week, although it would attempt to make collections in Aberystwyth on Tuesday.
Its workers will also try and collect refuse in Cardigan town on Christmas Eve.
Residents in other areas of the county have been asked to store their waste until the next collection date.
A council spokesman said: "Despite our priority highway network being open, many of our minor roads remain in a condition where it could be dangerous to drive heavy vehicles over them.
"The vast majority of our domestic waste collection routes do involve minor roads, therefore it's safer for us suspend the majority of collections at the moment."
Last month, Ceredigion council unveiled a new fleet of hi-tech refuse lorries to spearhead a waste collection scheme.
Its seven Mercedes Benz trucks have cost £156,000 each.
The authority replaced some weekly refuse collections with a fortnightly scheme to help hit collection targets.
Under the new scheme, household waste is being collected every two weeks, while food and recycling is being taken away every week.
