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.

Remnants of Tropical Storm Chantal could dump up to 5 inches of rain on Maryland. Flash flooding and rip currents are possible.
