. Despite the predictions for slow development from the tropical weather lookouts, it was possible that the system developed a surface low center near Belize City, Belize late on July 28. After the system moved inland over the Yucatán Peninsula, it became disorganized, although the National Hurricane Center indicated in the tropical weather outlook that once it moved into the Gulf of Mexico

 there was potential for development. Although the outflow of the system had appeared impressive on satellite images, the potential for development seemed uncertain, mostly due to the close proximity to land. The storm quickly became better organized based on satellite data and ship reports.

Almost immediately after emerging into the Gulf of Mexico on July 30, the cloud pattern of system quickly became better organized. Later after emerging into the Gulf of Mexico, ships and satellite images confirmed that Tropical Depression Four had formed offshore of the north coast of the Yucatán Peninsula; although it was likely that the depression formed 80 miles (129 km) north of the Yucatán Peninsula several hours earlier than confirmed. The following morning after development occurred, the depression had intensified into a tropical storm 575 miles (920 km) southeast of Texas

; the National Hurricane Center assigned it to the name Chantal. Although it became a tropical storm early that morning, the system was not upgraded to a tropical storm until reconnaissance flight confirmed tropical storm force winds about six hours later, when sustained winds were already 50 mph (85 km/h). Tropical Storm Chantal rapidly strengthened thereafter, with the National Hurricane Center satellites using the Dvorak technique to indicate t-numbers range from 2.5 to 3.5 within just twelve hours. Chantal continued to intensify, and headed northwestward at 11 mph (18 km/h) due to weak ridging over Florida

.

Later on July 31, satellite imagery revealed better organization, and another reconnaissance flight found winds at 91 mph (151 km/h) while flying at 1500 feet (457 m). Based on these discoveries, it was estimated that Chantal had intensified into a hurricane early on August 1. Hurricane Chantal continued to intensify, slightly, and attained its peak intensity on August 1 at 1000 UTC, reaching maximum sustained winds of 80 mph (130 km/h) and a minimum barometric pressure of 986 millibars. Only three hours thereafter, Hurricane Chantal made landfall near High Island, Texas
