Tropical Storm Isaias intensifies as shoppers stockpile water, food, essentials

Tropical Storm Isaias is intensifying as it moves toward the United States, prompting residents in areas from Louisiana to the Florida Panhandle to stockpile essential supplies. Meteorologists expect the system to strengthen into a Category 2 hurricane by Friday.

If the storm reaches this projected intensity, it will mark the first hurricane of the current season. Authorities have issued hurricane warnings across the affected regions as the system continues to develop.
