From a Washington Post story by Matthew Cappucci headlined “Ophelia strengthens and could become hurricane before lashing East Coast”:

Tropical Storm Ophelia formed Friday afternoon and quickly strengthened close to hurricane strength. The strong tropical storm is set to drench the East Coast this weekend, bringing heavy rain in addition to strong gusty winds, rough surf and coastal flooding, the National Hurricane Center reported. Tropical storm warnings are in effect from Cape Fear, N.C., to the Delaware-Maryland border on the Delmarva Peninsula, with storm surge warnings blanketing a similar area.
