Jacksonville, FL – Scorching heat and powerful thunderstorms are set to disrupt Friday plans across Jacksonville, putting drivers on Highway 17 and throughout Duval County on high alert. With highs near 95°F and a heat index reaching 101°, residents face dangerous conditions even before storms begin rolling in after 2 p.m.
According to the National Weather Service in Jacksonville, Friday, July 11 will bring a 60% chance of afternoon showers and thunderstorms, followed by continued storm risks through Sunday. Southwest winds of 5 to 7 mph will offer little relief as humidity climbs and roads become slick. The NWS urges everyone to avoid non-essential travel during peak storm hours and to hydrate frequently. If you must travel, monitor local traffic updates—especially along I-295 and Highway 17, where sudden downpours may reduce visibility and cause hazardous driving.
By Friday night, temperatures will settle around 77°F, but the chance for evening storms remains high. Saturday heats up again to 96°F, with more afternoon storms possible, while Sunday keeps the pattern going—sunny mornings followed by stormy afternoons. This relentless summer weather could impact outdoor plans, sporting events, and even cause isolated power outages if strong winds develop.
Preparedness is key: charge mobile devices, secure outdoor items, and check on elderly neighbors. The heat, combined with unpredictable storms, can quickly become a safety risk, especially for children and pets.
Looking ahead, the extended five-day outlook shows rain and storms sticking around through Tuesday, July 15. Residents should stay weather-aware and be ready for updates as summer’s pattern of heat and storms continues across the region.
