Con Edison is working hard to avoid power outages that could raise in the next 24 hours because of power consumption.

This comes as the National Weather Service issued a heat advisory that begins Tuesday at 11 a.m.

Temperatures across New York City are expected to climb into the upper-90s by Wednesday. City officials are asking New Yorkers to follow a few guidelines to prevent outages.

GUIDE: Cooling centers around the tri-state area

Residents are urged to run appliances such as ovens, washing machines, dryers and dishwashers in the early morning or late at night to reduce heat in the home. Shades, blinds and curtains should be kept closed. The Office of Emergency Management says that about 40% of unwanted heat comes through windows. Residents are also urged to turn off air conditioners and lights when they are not at home to avoid burnouts.

Officials also say that thermostats should also be kept at 78 degrees. Although some New York residents took issue with this suggestion.

“Seventy-eight degrees is too hot,” one resident said.

The extreme temperatures should last through Wednesday night.
