Hurricane Bob was the first Atlantic tropical cyclone to be officially designated using a masculine name after the discontinuation of Joint Army/Navy Phonetic Alphabet names. Bob brought moderate damage to portions of the United States Gulf Coast and areas farther inland in July 1979. The storm was the first hurricane in the Gulf of Mexico to form in the month of July since 1959, and was the fifth tropical cyclone to form during the annual hurricane season. Though the origin of Bob can be traced back to a tropical wave near the western coast of Africa in late June, Bob formed from a tropical depression in the southwestern Gulf of Mexico on July 9. Tracking in a general northward direction, favorable conditions allowed for quick strengthening. Less than a day after formation, the system reached tropical storm intensity, followed by hurricane intensity on July 11. Shortly after strengthening into a hurricane, Bob reached its peak intensity with maximum sustained winds of 75 mph (121 km/h) and a minimum barometric pressure of 986 mbar (hPa; 29.12 inHg). At the same intensity, Bob made landfall west of Grand Isle, Louisiana, and rapidly weakened after moving inland. However, the resulting tropical depression persisted for several days as it paralleled the Mississippi and Ohio rivers. On July 16, the system emerged into the western Atlantic, where it was subsequently absorbed by a nearby low-pressure area.
