The storm has caused widespread damage across the southern United States, with significant flooding and power outages reported. Streets along the Gulf Coast were deserted following mandatory evacuations, and authorities have warned of ongoing hazards such as downed power lines and standing water. The NHC has issued warnings of considerable flash flooding and landslides, particularly in the Southern Appalachians, where communities are still recovering from previous storms. The storm's heavy rainfall, with some areas expected to receive up to 10 inches (25 cm), poses a major flood threat as Isaias moves inland (Source: AFP).
