Here is a look at the dangerous storm by the numbers:

17: The number of fatalities as of the afternoon of Sunday.

A 41-year-old mother and her 7-month-old son were killed in Wilmington, North Carolina, when a tree fell on their home, officials said. The woman's husband was injured in the incident and taken to a nearby hospital, according to police.

A 78-year-old man in Kinston, North Carolina, was electrocuted when he tried to connect two extension cords outside in the rain, according to Lenoir County Emergency Services Director Roger Dail.

A 77-year-old man in Lenoir County, North Carolina, fell and died from "a cardiac event" while checking on dogs outside during the storm, officials said.
