Republican Secretary of State and Lt. Gov. Kim Guadagno said Thursday county clerks' offices have been ordered to remain open this weekend to help process mail-in ballots.
Voters will be able to go to the clerks' offices through Tuesday to fill out mail-in ballots and hand them in.
Requests for mail-in ballots are typically accepted by mail up to a week before an election and in person until 3 p.m. the day before an election.
Guadagno says it's unclear how many of the state's 3,000 polling places have electricity but she will know better Friday. More than 1.7 million electric customers are without power.
