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.

Potential impacts include damage to porches, awnings, and mobile homes, scattered power outages, and road closures due to debris.

Tropical Storm Chantal formed in the Atlantic on Saturday morning and is projected to reach South Carolina's coast on Sunday, the National Hurricane Center said.
