Dangerous flooding from Tropical Storm Arthur, first of the Atlantic season, threatens Gulf Coast

Tropical Storm Arthur formed on Wednesday, marking the first tropical cyclone of the Atlantic basin season. The storm developed from a disorganized cluster of storms that had been affecting the Gulf Coast for several days. This weather system now threatens the Gulf Coast region with dangerous flooding. Authorities are monitoring the path of the storm as it organizes, following a period of instability that plagued the coastal areas prior to the official formation of Arthur.
