Q: Question: Which of the states that Tropical Depression Six covered on July 30 joined the United States of America first? Passage:In late July, a trough of low pressure, which Hurricane Blanche avoided, was situated over the northeastern Gulf of Mexico. The system developed into Tropical Depression Six at 12:00UTC on July28, while located about 60mi (100km) southwest of Cape San Blas, Florida. The depression combined with a building high pressure system, resulting in the development of a strong convergence zone. This, in turn, caused heavy rainfall along the Gulf Coast, particularly in southern Alabama and the Florida Panhandle. With sustained winds initially at 25mph (35km/h), the storm intensified slightly while tracking west-northwestward. Early on July29, the depression attained its peak intensity with maximum sustained winds of 35mph (55km/h) and a minimum barometric pressure of 1010mbar (29.83inHg). Several hours later, it made landfall in a rural area of St. Bernard Parish, Louisiana, with winds of 30mph (45km/h). The system curved northwestward and dissipated at 12:00UTC on July30, shortly after crossing into Mississippi. The remnants continued into northern Louisiana and then turned northward, before dissipating over Arkansas on August3.
