[2] The wave moved generally west-northwestward, producing occasional bursts of convection, finally arriving in the southeastern Gulf of Mexico by August 19, when animated satellite images began to indicate it had possibly developed a low pressure centre.

The system lingered for two days, lacking an organized low level centre of circulation until early on the morning of August 21, when advisories were initiated on the tropical depression, 185 miles (298 km) east of Brownsville, Texas.

[3] The depression became a tropical storm later that day, as it moved steadily west-northwestward, strengthening, and then weakening again before making landfall the next morning around Port Aransas, Texas.

[4] The storm moved slowly inland and finally dissipated on the morning of the August 24 near the town of Del Rio, Texas.

Ten days later, on August 19, satellite images indicated the disturbance was beginning to rotate cyclonically over the southeastern Gulf of Mexico.

[2] Tropical storm warnings were issued by the National Hurricane Center coincidentally with the first advisory on the depression, from High Island, Texas to Brownsville.

At landfall on August 22, the warnings north of Sabine Pass, Texas were expired, and the rest were dropped later that day.

A 90-mile (140 km) wide swath of over 3 inches (76 mm) of rainfall extended from the Middle Texas Coast west to the Texas-Mexico border.

Charley produced 17 inches (430 mm) of rain in Del Rio in a 24-hour period, a new record daily rainfall for the city.

In Val Verde County, Texas, which took the vast majority of the damage, roughly 2000 houses, mobile homes, and apartments combined were destroyed by flooding.

[2] At one point, two-thirds of Del Rio was underwater after a natural dam broke in the San Felipe Creek, flooding the city with a sudden surge of water.

[11] Four people, including two toddlers, died when their truck was swept away by floodwaters and nine more drowned in flooding along the San Felipe Creek.

Augosto received maximum sustained winds of 52 miles per hour (84 km/h) and recorded a minimum pressure of 1,003 millibars (29.6 inHg).
