ATLANTA (AP) — Most of the South — from Texas to parts of South Carolina — was under heat advisories and warnings as temperatures would feel as high as 117 degrees (47 Celsius), forecasters said.
The most intense heat Tuesday was expected in Mississippi, Arkansas, Louisiana, and Alabama; and in areas near Memphis, Tennessee.
The warnings come one day after the temperature and humidity combined for a Monday heat index of 121 degrees (49.4 Celsius) in Clarksdale, Mississippi. It was only a few degrees cooler in West Memphis, Arkansas.
By noon Tuesday, the heat index was already 117 degrees (47 Celsius) in Clarksdale; and 114 (46 Celsius) in the west Tennessee city of Dyersburg, the weather service reported.
Forecasters say the heat index is what the temperature actually feels like.
