The deep freeze has triggered a further round of cold weather payments, bringing the total cost of the relief so far this winter to more than £4m.
The postcode areas affected in the latest round of payments are BT27-29, 35, 39-46, 60-71 and 78-82.
People who are eligible for the £25 payments include pensioners and many people on income-related Employment and Support Allowances.
The cold weather payment is available when temperatures are recorded or forecast to be zero degrees celsius, or below, for seven consecutive days.
Temperatures have remained below freezing in many parts of Northern Ireland for a fortnight — dipping as low as -15 degrees in Katesbridge, Co Down.
A total of £1.53million will be paid to people who qualify for the payment and are living in the affected postcode areas. Social Development Minister, Alex Attwood, said people can expect to have their payment on, or around, Wednesday, December 15.
Cold weather payments are, in addition to the winter fuel 0ayments of £250 and over, made to people born on or before July 5, 1950.
