All of New York City is being asked to conserve power with Tuesday's extreme heat straining power systems and causing problems around the Tri-State Area. New York City's emergency notification system put out the alert from Con Edison asking New Yorkers to limit their power use.

The heat wave has arrived. Temperatures and humidity are climbing as the tri-state heads into an expected record-shattering heat wave, where it could feel like 100 degrees or hotter through Wednesday.

Dangerously hot temperatures gripped New York City and the Tri-State area again on Tuesday making it feel like a furnace outside and shattering records in the process. The official temperature in New York City reached 99 degrees in Central Park just before 4:00 p.
