    Downpours, Heat May Halt Holiday Weekend Travel

    Blinding downpours, severe thunderstorms and intense heat may cause travel delays on this last day of the holiday weekend.

    For areas in the South, "the biggest threat is flash flooding, heavy downpours and rounds of thunderstorms," said AccuWeather.com Meteorologist Brian Edwards. These threats extend from the central Gulf Coast to the central Appalachians and include the major cities of Panama City, New Orleans, Birmingham and Pittsburgh.

    The west coast of Florida will remain active on Sunday too, continuing to dump additional rain between Tampa and Fort Myers. That is especially true during the afternoon hours.

    The storms have the potential to cause not only more flash and urban flooding, but flight delays at major airports.

    AccuWeather.com meteorologists are concerned for the thunderstorms across the northern High Plains and from northern Virginia to central and eastern Pennsylvania to turn severe this afternoon.

    Meanwhile, another hot and humid day is shaping up for the I-95 corridor from Washington, D.C., to Boston. Temperatures will also crack the century mark across the central High Plains.

    AccuWeather.com Expert Senior Meteorologist Alex Sosnowski explained that the increased heat could cause some travel problems. Drivers should be cautious by reducing their speed Sunday. “Most people don’t realize that the faster you travel in the car, the hotter your tires will become. Since most cars don’t have racing tires, which compensate for this added heat, their tires can become too hot and cause them to blow out,” he said. Other essential safety tips include packing extra water and checking coolant levels in your vehicle.
