Cyclone Nargis storm status. By late on 29 April, convection had begun to rebuild, though immediate restrengthening was prevented by increased wind shear. On 1 May 2008, after turning nearly due eastward, Cyclone Nargis began rapidly intensifying, due to greatly improved outflow aided by an approaching upper-level trough. Strengthening continued as Nargis developed a well-defined eye with a diameter of 19 km (12 mi), and early on 2 May, the JTWC estimated that the cyclone reached peak 1-minute winds of 215 km/h (135 mph), as it approached the coast of Myanmar, making it a Category 4 storm. At the same time, the
Cyclone Nargis of 160 km/h (100 mph), and at the same time, the IMD classified the system as a very severe cyclonic storm. Initially, the cyclone was forecast to strike Bangladesh or southeastern India. Subsequently, the cyclone became disorganised and weakened due to subsidence and drier air; as a result, deep convection near the center markedly decreased. At the same time, the storm began a motion to the northeast, around the periphery of a ridge to its southeast. The circulation remained strong despite the diminishing convection, though satellite intensity estimates using the Dvorak technique indicated the cyclone could have weakened to tropical
