Dangerous heat smothers eastern and southern US
June 30, 2012 00:51
NASHVILLE - Temperatures in the triple digits were causing misery in the eastern and southern United States on Friday, with the country music capital of Nashville, Tennessee recording an all-time record of 109 degrees Fahrenheit (43 degrees Celsius).
Marked in pink on a Weather Underground map of the United States, a heat advisory spread like a rash over a third of the country, from Nebraska east to New York and south to Florida.
A heat advisory is typically issued when the heat index - a combination of temperature and humidity - exceeds 100 degrees and there is a risk of people and animals suffering heat exhaustion.
