Roads treacherous again tonight (Sunday)

Donegal County Council is again afvising against unnecessary journeys as compacted snow once again freezes, leaving treacherous conditions on untreatedoads and on footpaths. This is the text of a statement issued by the council this evening.
Weather alert issued by Donegal County Council this evening, 5th of December 2010.
Donegal County Council are managing their limited salt supplies by using a 50:50 mixture of salt and grit to treat priority routes. The weather conditions have changed in the past 48hours from heavy show, to freezing conditions with showers of rain and sleet.
This change resulted in widespread black ice and treacherous road conditions on Saturday and Sunday mornings . These conditions, which are expected to persist into the middle of next week, are forecast to be compunded by local heavy falls of snow across the county early on Monday.
An Garda Siochana have asked the public to avoid travelling during these conditions. Donegal County Council are appealing to the widespread public to heed this advice, and to refrain from travelling if at all possible over the coming days. They have further advised that where travel cannot be avoided, a much reduced speed should be used and increased care taken, as motorists can expect black ice and treacherous conditions, even where roads have been treated.
The National Roads Authority (NRA) have advised that national salt supplies are adequate but must be carefully managed to ensure priority routes  are dealt with, however long the cold weather continues  – the cold spell is predicted to last until the end of the coming week.  The NRA  are distributing salt on a carefully managed basis.
