Annandale, Virginia – Relentless summer heat returns to Annandale as dangerous humidity and thunderstorms threaten the region starting Thursday, July 17th. Commuters on Route 236 should plan for slowdowns and possible flooding after 2 p.m., when the risk of storms peaks and heat index values soar to nearly 100°F.
According to the National Weather Service, Thursday’s high will reach 95°F, with southwest winds driving humidity across Fairfax County. Afternoon storms may produce heavy rain, gusty winds, and localized flooding, especially in low-lying areas and near major routes such as Route 236 and Little River Turnpike. Residents should avoid unnecessary travel during peak storm hours, keep cell phones charged, and secure outdoor items to prevent damage.
Friday offers little relief as highs again hit 90°F, with more afternoon storms possible. The threat continues into Saturday, bringing repeated chances for showers and storms throughout the weekend.
