India is launching programs to protect people from extreme heat in two high-risk cities, after a devastating heat wave killed at least 2,500 people across the country last year.

By introducing seven-day weather forecasts, extra water supplies, cool-air shelters and afternoon breaks for workers, India hopes to help millions of impoverished workers stay safe in high heat.

The government worked with the New York-based National Resources Defense Council in putting the program together.

The council said Wednesday it will be launched over the next week in the eastern city of Bubaneswar and the western temple town of Nagpur, where temperatures hit a sweltering 47 degrees Celsius (117 degrees Fahrenheit) last May.
