The stormy weather poses risks for travelers and those planning outdoor activities, including Memorial Day ceremonies, parades, and cookouts. Heavy rain and lightning could lead to travel delays and event cancellations, particularly in areas from Texas to West Virginia. Beachgoers in the Northeast may face cooler temperatures, 30 to 50 degrees lower than earlier in the week, and limited opportunities for outdoor recreation due to storms. The AAA warns that the high volume of travelers could exacerbate delays caused by weather-related disruptions.
