Wilmington, North Carolina – A surge of July heat and powerful thunderstorms will hit Wilmington and nearby areas on Thursday, July 17th, threatening afternoon commutes, outdoor plans, and local roadways such as US-17 and US-74. Temperatures will push into the low 90s, but humidity will send the heat index soaring to near 100°, just as storms develop after 2 p.m. Residents should limit time outside and secure loose items ahead of Thursday’s active summer weather.
According to the National Weather Service, scattered thunderstorms will move into Wilmington and Belville late Thursday afternoon, bringing the risk of damaging winds, brief downpours, and dangerous lightning. Isolated power outages and minor flooding are possible, especially along low-lying roads and intersections near the Cape Fear River. Rain may linger into the evening, so drivers should expect sudden slowdowns and potential delays on main arteries including US-17 and NC-133.
High heat and muggy conditions will persist into the weekend, with Friday offering a repeat chance of afternoon storms. Saturday looks even hotter, as highs reach 95°, though another round of storms could cool things off by evening. Beachgoers and boaters should monitor the sky closely and be ready to take cover if thunder rumbles.
Locals are urged to check forecasts before travel, hydrate frequently, and avoid strenuous activities during the hottest hours. Charge your devices and report downed power lines to Duke Energy if storms cause outages.
Storm chances continue Sunday and into Monday night, keeping the threat for lightning and localized flooding in play. By Tuesday, drier air returns, but highs remain near 90°.
