Roughly a fifth of Fulton County’s early voting sites were still without electricity Thursday afternoon following metro Atlanta’s brush with Hurricane Zeta.

The following seven sites had no power as of 3:15 p.m., according to the county: Wolf Creek Library, South Fulton Annex, Chastain Park Gym, Milton Library, Ponce de Leon Library, New Beginnings Senior Center and Adams Park Library. The county reported the first six as not having power at 12:20 p.m.

The county has deployed its two mobile voting units, which are $350,000 buses that hold eight devices where voters can cast ballots. They will be stationed at Wolf Creek Library and Milton Library until 7 p.m. on Thursday.

A million Georgians woke up Thursday without power due to the storm.

County officials had been planning for the last-minute rush of early voters, with roughly 30,000 expected on Friday alone — but that was before the storm blew through and might have prevented or discouraged voters from venturing out Thursday.

A county spokeswoman said that Fulton staff have been in touch with Georgia Power, but they have no have specific estimates on when power will be restored.

According to the county’s online wait time tracker around 4 p.m., most of the open sites have no wait and the longest wait countywide is 30 minutes.

This is expected to be Fulton’s busiest election ever, with estimates of an 80% turnout of the county’s roughly 800,000 registered voters.
