Donegal experienced some of the lowest temperatures of the severe weather on Sunday night with -15C recorded.
Killygordon maintained its reputation as the county's coldest spot as the mercury dropped to -15.7. But temperatures dropped below -10 across the county.
Temperatures stayed below zero in most parts of the county yesterday meaning conditions on roads and pavements stayed treacherous.

The temperature in Killygordon was -4.5, -3.9 was recorded in Bundoran and the temperature was at -3.4 at Lough Mourne. Road temperatures were even lower at the same time with -7.9 recorded at Burt.
