No break from the heat Wednesday

The National Weather Service in Omaha/valley has issued a heat advisory, which is in effect from noon to 8 p.m. Wednesday, for all of southeast Nebraska, southwest Iowa and northwest Missouri.

High temperatures are expected to be in the mid to upper 90s with heat index readings around 105 degrees during the afternoon and early evening hours.

Prolonged exposure to heat and humidity may lead to  heat-related illness if precautions are not taken.

Precautionary/preparedness actions: 

A heat advisory means that a period of hot temperatures is expected. The combination of hot temperatures and high humidity will combine to create a situation in which heat illnesses are possible. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.

Take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, so call 911.
