A heat advisory is in effect for Union County from 10 a.m. to 7 p.m. tonight.

According to the National Weather Service in Shreveport, the advisory is in effect for much of southwest Arkansas, as well as southeast Oklahoma and northeast Louisiana. It is the second consecutive day for the advisory in Union County, as one was in effect from 10 a.m. to 7 p.m. Thursday as well.

High pressure, hot temperatures and high humidity levels are combining for high heat index values, which could reach around 105 degrees Fahrenheit, according to the weather service. Heat-related illnesses may be possible for those spending time outdoors without shade and without taking proper precautions.

To avoid a heat-related illness, the weather service advises residents to recognize signs and symptoms of heat exhaustion and heat stroke.

According to the Mayo Clinic, such signs include heavy sweating, faintness, dizziness, fatigue, muscle cramps, low blood pressure when standing, nausea, vomiting, headache and a weak, rapid pulse or rapid shallow breathing.

People are advised to wear light-weight and loose-fitting clothing and to drink plenty of water. If possible, stay in air-conditioned rooms and check up on relatives and neighbors. It is also advised to ensure pets have access to fresh, cool water.

The hot weather is expected to stick around through the weekend and early next week.
