Hidalgo County announced on Tuesday that the polls will remain open until 8 p.m. — an hour later than normal.

Ten polling places experienced problems Tuesday morning, which temporarily prevented some voters from checking in.

All 74 polling locations in Hidalgo County are now open and operating normally.

“Making sure our voters have the opportunity to cast their ballot is our utmost priority,” Elections Administrator Yvonne Ramón said in a news release. “Extending the closure of the polls to 8 p.m. will provide that opportunity to the voters of Hidalgo County.”
