Tropical cyclones typically drop large amounts of rain along and near the storm's path. The slower and more significant the storm’s size, the higher the likelihood of higher rainfall totals. Some storms can drop well over 30 inches of rainfall, like when Hurricane Harvey dropped over 60 inches near Nederland, Texas, in 2017.

Chantal downgraded to a tropical depression over the weekend and was moving northeast through Virginia early morning Monday as flash flood threats continued near the storm, forecasters say. There have been no local impact in Louisiana.
