By 0600 UTC, a ragged 75 km (45 mi) wide eye developed over the center of circulation, indicating it had become a typhoon.
By the afternoon of August 1, a strong central dense overcast, an area of high, thick clouds, developed over the center of circulation, prompting the NHC to upgrade it to a Category 1 hurricane on the Saffir Simpson Hurricane Scale.
Shortly after, a central dense overcast, a large area of deep convection, developed over the center of circulation and large banding features developed along the periphery of the cyclone.
By 0600 UTC on February 12, the system's outflow improved and a small area of deep convection, known as the central dense overcast, developed over the center of circulation.
On August 22, as it passed 140 mi (225 km) to south of the Cape Verde islands, deep convection developed over the center of circulation, and early on August 23 the depression intensified into Tropical Storm Debby about 300 mi (485 km) southwest of Cape Verde.
Late on August 3, deep convection developed over the center of circulation again, though persistent vertical shear weakened Chris to a tropical depression on August 4. Due to computer models predicting lesser amounts of shear, forecasters indicated the possibility of moderate strengthening in the Gulf of Mexico to a 60 mph (95 km/h) storm.
As the upper-level low over Texas drifted southwestward, an anticyclone developed over the system, with the circulation becoming better defined and more vertically aligned.
Moving westward for much of its existence to the south of a narrow subtropical ridge, an upper level high developed over the strengthening low level circulation early on June 19, which became a tropical depression that day.
As the previous depression dissipated over India, a new circulation developed over the Bay of Bengal on August 12.
Very deep, symmetrical convection developed over the poorly defined center of circulation while banding features began to form, although ill-defined outflow and land interaction with the Baja California Peninsula initially prevented further strengthening.
