Turnout is predicted to be larger than 2016
An increased voter turnout is expected at the Assembly election tomorrow.
It is understood staff at the Electoral Office of Northern Ireland have been told to prepare for a larger turnout than last year's Assembly poll.
It also comes after the recent UTV election debate experienced a significant audience increase with 141,000 viewers. That was up some 42% compared to last year's televised debate.
The leaders of Northern Ireland's five biggest parties took part in the programme two weeks ago.
It attracted a 23% share of the total viewers.
Tomorrow's weather may also encourage a higher turnout as it looks set to be dry for most of the day.
Last year's election saw 703,744 votes cast, representing 54.9% of those eligible to vote in Northern Ireland.
That figure was down compared to the 2011 election, which saw a 55.7% turnout.
Turnout was highest in Fermanagh and South Tyrone at 64.6%, and lowest in North Down at 49.6%.
Turnout increased in eight Assembly constituencies and declined in 10.
