Heat advisory, extreme heat watch hit Quitman County through July 2
Marks faces heat index values near 109 degrees as a Heat Advisory gives way to an Extreme Heat Watch through July 2, raising risk for older adults and outdoor workers.
Heat index values near 109 degrees were forecast for Marks as Quitman County sat under a Heat Advisory from June 28 at 11 a.m. CDT until June 29 at 11 a.m. CDT, followed by an Extreme Heat Watch from June 29 at 11 a.m. CDT through July 2 at 8 p.m. CDT. The National Weather Service forecast sunny, hot conditions that will keep dangerous heat in place across the Mid-South, with some places reaching 110 degrees or higher. In Marks, that makes the hottest part of the day the most dangerous time for families trying to run errands, workers on the road and children spending time outside.
The risk is sharper in a county where older adults make up a significant share of the population. Census Bureau QuickFacts puts Quitman County at 6,176 residents in the 2020 census, an estimated 5,364 on July 1, 2025, and 18.3 percent age 65 or older. People 65 and older are more prone to heat-related illness, and people with chronic medical conditions are also more vulnerable because illness and medication can affect how the body responds to heat.
Public health guidance for the stretch is straightforward: stay in air-conditioned buildings as much as possible, drink plenty of fluids and avoid strenuous outdoor activity during midday heat. Check on family members, older adults and neighbors. People without air conditioning should plan ahead and can call 2-1-1 or contact local health or emergency management agencies to find cooling options. Heat cramps, heat exhaustion and heat stroke are the warning signs to watch for as heat exposure worsens.
The warning also reaches into daily life in Marks, where field work, youth sports and long drives between errands can all become riskier when heat index values stay in the triple digits. Households that depend on a hot vehicle or a poorly cooled home will have less margin for error, and air conditioners will draw harder as more people try to stay indoors. The National Weather Service Memphis office identifies the pattern as a heat dome, and the Climate Prediction Center’s June 28 hazards outlook shows extreme heat likely to continue into week 2 across much of the central and eastern contiguous United States.
NOAA’s National Centers for Environmental Information recorded record heat to more than 100 million people across 726 counties from June 22 to 25.
