 A low pressure area of non-tropical origins developed into Subtropical Storm Ana at 00: 00 UTC on May 8, while situated about 175 miles (280 km) southeast of Myrtle Beach, South Carolina. The system was classified as subtropical due to its involvement with an upper trough, as well as its large wind field. Throughout the day, convection progressively increased as Ana moved north-northwestward across the warm sea surface temperatures associated with the Gulf Stream. At 00: 00 UTC on May 9, the cyclone attained its peak intensity with maximum sustained winds of 60 miles per hour (95 km / h) and a minimum barometric pressure of 998 millibars (29.5 inHg). Six hours later, Ana transitioned into a fully tropical system. However, the storm soon began weakening after moving away from the warm waters of the Gulf Stream and increasing wind shear also contributed to the deterioration of Ana. Around 10: 00 UTC on May 10, the system made landfall near North Myrtle Beach, South Carolina, with winds of 45 mph (75 km / h). Ana weakened to a tropical depression just eight hours later and transitioned into a remnant low near the Delmarva Peninsula at 00: 00 UTC on May 12. The remnant low merged with a frontal system about 24 hours later.
