Extreme heat wave: 100m Americans asked to stay in

More than 100 million Americans are being warned to stay indoors -- if possible -- as high temperatures and humidity settle in over states stretching through parts of the Gulf Coast to the Great Lakes and east to the Carolinas.

The National Weather Service Prediction Center in College Park, Maryland, said Monday 107.5 million people will be affected by combination of heat advisories, excessive heat warnings and excessive heat watches through Wednesday, reports AP.

The heat wave, which set several high temperature records in the West, the Southwest and into Denver during the weekend, moved east into parts of the Gulf Coast and the Midwest Monday and will expand to the Great Lakes and east to the Carolinas, the National Weather Service said.

St Louis, Memphis, Minneapolis and Tulsa are among several cities under excessive heat warnings, with temperatures forecast to reach about 100 degrees Fahrenheit (38 degrees Celsius), accompanied by high humidity that could make conditions feel close to 110 degrees Fahrenheit (43 degrees Celsius).

In Jackson, Mississippi, residents braved temperatures reaching 95 degrees Fahrenheit (35 degrees Celsius) on Monday to complete their chores. Roger Britt, 67, ventured to a neighborhood garden in search of vegetables for dinner.
