aircraft of tropical-storm force winds, the NHC upgraded the system to Tropical Storm Arthur at 00:00 UTC on May 17. Being steered generally north-northeast for the next several hours, Arthur stayed well offshore of the coasts of Florida and Georgia. However, a mid-level trough centered over the United States caused Arthur to slowly be pushed northeastwards over a section of relatively cool waters and as a result most of the storm's convection became limited to the east of the circulation. Despite a lopsided structure, reconnaissance aircraft found Arthur slightly stronger, despite its appearance on satellite.
