The National Weather Service has issued an excessive heat warning for much of Arkansas, including Southeast Arkansas. Highs will be in the 90s, with heat index values from 100 to 110 degrees. Heat indices are expected to exceed 110 degrees in many locations Tuesday afternoon.

Hot weather will increase the risk of heat related illness, including heat exhaustion and heat stroke. The very young, the elderly, and those without access to air conditioning will be especially vulnerable.

If you must be outdoors, the occupational safety and health administration recommends taking frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. If heat stroke is suspected, call 911.

An Excessive Heat Warning means that a prolonged period of dangerously hot temperatures will occur. The combination of hot temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors.
