Jackson, Miss. – Dangerous heat will grip communities along the Louisiana-Mississippi border today, with heat index values expected to peak near 109 degrees by midafternoon. The National Weather Service warns conditions could become dangerous for anyone without access to cooling through 7 p.m. Monday.
According to the NWS in Jackson, the heat advisory covers northeast Louisiana’s Madison, Franklin, Catahoula, Tensas, and Concordia parishes, along with Mississippi’s Warren, Hinds, Claiborne, Jefferson, and Adams counties. Cities including Jackson, Natchez, Vicksburg, and Vidalia are in the highest risk zone.
Officials urge residents to stay indoors in air-conditioned spaces whenever possible, avoid strenuous activity during peak heating, and drink plenty of water. Employers should schedule frequent breaks in shaded or cooled areas for outdoor workers. Signs of heat exhaustion include dizziness, headache, and heavy sweating; heat stroke symptoms require an immediate 911 call.
Conditions are expected to ease after sunset, but high humidity will keep the area warm into the night. The National Weather Service says more advisories may be issued if extreme heat persists into Tuesday.
