Tropical Storm Claudette was the fourth named storm of the 1997 Atlantic hurricane season. Claudette developed from a non-tropical frontal low that absorbed Hurricane Bill earlier in the season. The low eventually acquired tropical characteristics, and developed into Tropical Storm Claudette, located well east of the East Coast of the United States. Claudette moved north, then east, and dissipated on July 16, after forming on July 13.
Claudette caused no damage, and no fatalities.

Claudette formed from a frontal low that was generated a few hundred miles east of Georgia and South Carolina on July 11, by the non-tropical frontal low that had absorbed Hurricane Bill earlier in the season. For the next two days, the low moved very little, and it gradually acquired tropical characteristics by acquiring a closed low-level circulation, which was independent of the frontal band dissipating in the vicinity of the low. At 0600 UTC on July 13, the low became a tropical depression, while located 275 miles south-southeast of Cape Hatteras, North Carolina. After forming, the depression became Tropical Storm Claudette 12 hours later, based on 45-50 knot winds measured at a flight level of 750 feet during the first reconnaissance aircraft flight into the system. Around this time, convective banding features increased enough within Claudette for Dvorak T-Numbers to reach 2.5. Claudette developed despite strong south to southwesterly wind shear. This same shear also kept Claudette from developing anything more than a weak anticyclone above it.
From July 13 to July 16, Claudette retained 30-40 knot winds near its circulation center. Claudette initially moved northward, but then eventually turned eastward, due to the flow ahead of an approaching frontal boundary. Claudette merged with the front on July 16, with its center once again becoming a frontal low, becoming an extratropical cyclone because of this. Claudette's extratropical remnants moved east over the following week. Satellite images suggested the remnants of Claudette dissipated near the Azores on July 23.
Lack of Retirement
Because Claudette did not affect land, the name was not retired in the Spring of 1998 by the World Meteorological Organization. It was used again in the 2003 Atlantic hurricane season, and is on the list of names to be used for the 2009 Atlantic hurricane season.
