Thus, Nadine regenerated back into a tropical storm at 0000 UTC on September 23. Another blocking ridge over the Azores forced Nadine to move west-northwestward on September 24, causing it to execute a small cyclonic loop. Although winds increased to 60 mph (95 km/h), the storm weakened again and decreased to a 45 mph (72 km/h) tropical storm on September 25.[1] Despite this, satellite imagery indicated that Nadine developed an eye-like feature.[25] However, the National Hurricane Center later noted that it was a cloud-free region near the center of the storm.[26] By September 26, Nadine curved south-southwestward to southwestward around the southeastern portion of a mid- to upper-level ridge located over the western Atlantic.[1]
