# Louisiana heat wave and its impacts > Live situation record from CLSTR: https://clstr.news/situations/louisiana-heat-wave-and-its-impacts > Updated: 2026-08-19T14:38:10.000Z. Sources: 4. Developments: 2. A heat wave in Louisiana has led to extreme temperatures, causing significant safety concerns and infrastructure issues. Early reports highlighted how ambient temperatures of 95°F or higher could push vehicle dashboard temperatures above 160°F, creating a greenhouse effect capable of baking food and posing deadly risks to living beings. As the heat persists, the impact has expanded to include infrastructure damage such as buckling roads and power outages. The extreme heat is also identified as a risk to automotive health, specifically regarding car batteries, which may face accelerated deterioration and fluid evaporation due to the intense thermal stress. Recent warnings from the National Weather Service in Shreveport indicate heat indices may reach between 110 and 113 degrees across Louisiana and the Ark-La-Tex region. This extreme heat poses specific risks to personal items left inside vehicles. Experts note that medicines and vitamins may undergo chemical degradation, sunscreen can lose UV protection, and hand sanitizer may evaporate. Additionally, single-use plastic water bottles may leach chemicals into water, while cosmetics and eyewear can warp or spoil. The heat also places increased strain on vehicle air conditioning systems and can exacerbate issues in worn-out components. ## Timeline ### 2026-08-19: Louisiana heat wave threatens vehicles and personal items Extreme heat in Louisiana, with heat indices reaching up to 113 degrees, is threatening vehicle components and making common items like medicine, sunscreen, and plastic water bottles unsafe. 4 sources. https://clstr.news/cluster/louisiana-heat-wave-poses-risks-to-vehicles ### 2026-07-22: Louisiana Heat Turns Car Dashboards into Ovens, Bakes Cookies Louisiana heat can raise car dashboards above 160 °F, baking cookies in a few hours and underscoring deadly interior temperatures that threaten children and pets. 2 sources. https://clstr.news/cluster/louisiana-heat-turns-car-dashboards-into-ovens-bakes-cookies --- Cite as: Louisiana heat wave and its impacts.
