It's a scorcher in New York City.

On Tuesday, June 24, as residents of the five boroughs headed to the polls to cast their ballots in what promises to be a unique primary election, heat radiated off the concrete.

The city is expected to break 100° by midday, and officials have sent out a heat advisory, urging residents to stay hydrated and cool, whether on their way to work or to the polling station.

Whether the heat wave will affect voter turnout remains to be seen, but candidates have already begun to express concern over the Board of Elections' ability to handle any potential power outages at polling stations should they arise.
