Should precincts have to be moved, Tennant said officials would spread word of the changes through local media.
However, no one will directly call voters in affected precincts to alert them of the changes.
Tennant said that was a consensus decision made by her office and county clerks statewide.
Prior to several recent elections, the Secretary of State's office and county clerks received complaints from voters reporting fraudulent phone calls saying their precinct location had been changed.
"We're not going to use that method just because we don't want to play in the hands of some unscrupulous overt plot," Tennant said.
She said signs also would be posted at closed precincts to instruct voters on where to go.
Early voting has resumed in all 55 counties, she said.
Tennant is encouraging people to drop by their county early voting location as they are out this weekend. That could help them avoid complications on Election Day. But she said people should go out only if it is safe to do so in their region.
For counties that use electronic voting machines, Tennant said those machines have battery power that would help them function even if generators go down. She also said county clerks are supposed to have some backup paper ballot stock as part of normal contingency plans.
County clerks also can use blank absentee ballots as backup on Election Day.
While several unknowns remained Thursday about polling location status, Tennant said she wasn't too concerned yet.
She said early voting activity has picked up in counties, and county clerks have been doing a good job of getting ready and meeting deadlines for this election.
She was confident they could quickly adapt to any changes the storm may cause.
"I'm not at the worrying point yet," Tennant said. "If this were Saturday or Sunday, even Monday, then the worry would come into play."
