Jackson, MS – Mississippi residents, particularly in Bolivar, Sunflower, and Leflore counties, are preparing for dangerously high temperatures today, as the National Weather Service has issued an extreme heat warning that remains in effect until 8 p.m. on Monday, July 21, 2025. With heat index values soaring up to 115°F, the combination of high temperatures and humidity poses serious health risks, especially for vulnerable populations such as the elderly, children, and those with underlying health conditions.
The warning affects a large portion of north-central and northwest Mississippi, including cities like Ruleville, Cleveland, Greenwood, and Indianola. These areas are expected to experience extreme heat throughout the day, and the National Weather Service is urging residents to take immediate steps to protect themselves from heat-related illnesses such as heat exhaustion and heat stroke.
The heat will be exacerbated by high humidity, which makes it feel even hotter. To mitigate the risks, the National Weather Service advises residents to stay well-hydrated, avoid direct sun exposure, and check on elderly family members and neighbors who may be more susceptible to the heat. Wearing lightweight, light-colored clothing is also recommended, as it helps to keep the body cool.
Motorists are advised to take extra care, as vehicles can heat up quickly, reaching life-threatening temperatures within minutes. Authorities are strongly urging against leaving children or pets unattended in vehicles, as this can lead to tragic outcomes in a matter of minutes.
For those who must be outdoors, it’s crucial to avoid strenuous activities, especially during peak heat hours between noon and 4 p.m. If any signs of heat illness, such as dizziness, heavy sweating, or nausea, occur, individuals are urged to move to a cooler environment, rest, and hydrate immediately.
The heat warning is in effect through the evening, but conditions could worsen, so residents are advised to remain alert for any updates or additional warnings. Staying informed and taking necessary precautions will be critical in navigating today’s extreme heat safely.
As the heat wave continues to affect Mississippi, prioritizing safety and protecting against heat-related illnesses will help residents stay safe during this dangerous weather event.
