Parts of South and Midwest grapple with unsafe heat wave

Parts of South and Midwest grapple with unsafe heat wave

An Excessive Heat Watch has been issued for Wednesday and Thursday of this week, according to the National Weather Service.

A Heat Advisory means that a period of risky heat is expected. Heat exhaustion can make you faint or feel dizzy, can cause excessive sweating, cool, pale, clammy skin, nausea or vomiting, rapid, weak pulse and muscle cramps. "That is, people tend to take advisories seriously and follow heat safety precautions, but if there's no advisory, people aren't as cautious".

"Research from surrounding areas has shown that heat-related illnesses seem to peak just below advisory thresholds", Palmer said. But, those who must be outside should drink plenty of water, wear sunscreen, and wear light clothing.

Anyone overcome by heat should be moved to a cool and shaded location.

Cooling stations were open in several cities, including Tulsa, Memphis, and Little Rock, Arkansas, officials said.

The region hardest-hit by the heat wave could experience many more days each year when the heat index soars as the effects of climate change increase, scientists say. It's not about what you see, it's about how your body responds to the heat.

"Texas and Florida stand out, but also of course Louisiana, and MS and the whole area all the way up to North Carolina", said Caldas, a climate scientist.
