Danny continued its track towards South Carolina while slowly strengthening, subsequently reaching its peak intensity at that day of 45 mph (72 km/h) and a minimum central pressure of 1,009 mbar (29.8 inHg) at 18:00 UTC.

Danny was one of three systems to make landfall on the U.S. state of South Carolina in the month of June, the others being Hurricane One in 1867 and Tropical Depression One in 1979.

[1] Over the next few days, the trough moved west-northwestward, and on June 26, the National Hurricane Center (NHC) began to monitor the disturbance for development as it passed several hundred miles south of Bermuda.

[2][3][4] On June 27, ship observations, buoy, and satellite imagery revealed that a small area of low pressure had developed about 500 miles (800 km) east-southeast of the Georgia-South Carolina border.

[1][9] Thus, it is estimated that Danny reached its peak intensity with maximum sustained winds of 45 mph (70 km/h) and a minimum barometric pressure of 1009 mb (29.80 inHg) at 18:00 UTC on July 28.

[11] Upon entering the east-central portion of Georgia, the system weakened to a tropical depression as evidenced by Doppler weather radar velocity data and surface observations.

[1] Danny's tropical cyclogenesis was poorly forecast due to the disorganized nature of the precursor disturbance and low model confidence.

[1] A Tropical Storm Warning was issued from Edisto Beach to Santee River in South Carolina at 15:00 UTC on June 28.

[12] The warnings in the state from Danny were canceled at 03:00 UTC on June 29 as the system weakened to a tropical depression, inland Georgia.

[16] Despite Danny being predicted not to bring any major impacts to the Southeastern United States, portions of Georgia, South Carolina, and northern Alabama were expected to see increased rainfall from the system, causing the potential of flash flooding.
