Wilmington, Delaware – Drivers in Delaware should prepare for possible slowdowns along I-95 and Route 1 Saturday afternoon as thunderstorms return to the region. Afternoon highs will approach 90°F, and a quick burst of heavy rain could cause ponding on major roadways, especially during late-day travel. Residents should limit outdoor plans during peak storm hours and secure loose items that could blow around in gusty winds.
According to the National Weather Service in Mount Holly, storm chances rise after 2 p.m. Saturday, with the best activity over northern and central Delaware. Rainfall could reach a quarter inch, with brief downpours lowering visibility for drivers. While Saturday morning looks dry, conditions could change quickly.
Sunday will bring another round of heat, topping near 90°F, with storm chances increasing after 8 p.m. into early Monday. Monday and Tuesday will trend cooler, with highs in the low 80s and lower humidity.
Beachgoers should watch for lightning risk during the weekend, and boaters should stay aware of quick-forming storms. Light winds mean storms could stall, increasing localized flooding concerns. Keep weather alerts active and avoid flooded intersections.
Storm threats taper by Tuesday, leaving a mostly sunny stretch midweek. More unsettled weather could return late Thursday or Friday.
