Lafayette County is under Heat Advisory from 11 a.m. today until 8 p.m. Tuesday for dangerously hot conditions with heat index values up to 107. The county has also been placed under Excessive Heat Warning today from 11 a.m. to 8 p.m.

This advisory affects portions of North Mississippi, West Tennessee, East Arkansas and Southeast Missouri.

Residents will experience extreme heat and humidity that could significantly increase the potential for heat-related illnesses, particularly for those working or participating in outdoor activities.

Several days of heat index values above 100 degrees are expected this week. The effects of heat stress can increase with prolonged exposure over consecutive days.

Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors. Young children and pets should never be left unattended in vehicles under any circumstances. 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 lightweight and loose-fitting clothing when possible.

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.

A heat stroke is considered an emergency and you are advised to call 911 should one occur.
