Extra beds are being made available for rough sleepers due to the bad weather.
A spokesperson for the Department of Housing said additional capacity has been put in place.
This is to ensure that there are additional bed spaces available for rough sleepers that would not normally avail of homeless services.
CEO of the Peter McVerry trust has asked for people to contact them should they see anyone sleeping rough tonight.
"We've increased the teams tonight across Dublin. There will be three teams out tonight in vehicles across the city."
"If you spot somebody, text or email it in to us and we'll go and pick them up - we picked up a 19 year old in the Phoenix Park this morning."
