Tropical Storm Chantal was a North Atlantic tropical cyclone that moved across the Caribbean Sea in August 2001. Chantal developed from a tropical wave on August 14 in the tropical Atlantic Ocean. It tracked rapidly westward for much of its duration, and after degenerating into a tropical wave it passed through the Windward Islands. Chantal reached a peak intensity of 70 mph (110 km/h) twice in the Caribbean Sea, and each time it was anticipated to attain hurricane status; however, wind shear and later land interaction prevented strengthening to hurricane status. On August 21 Chantal moved ashore near the border of Mexico and Belize, and the next day it dissipated.
