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 Giri Cyclone Nargis which struck the Irrawaddy Delta region as a low-end Category 4 equivalent in May 2008. However, according to the International Federation of Red Cross And Red Crescent Societies, substantial weakening had taken place within the hours before landfall; they estimated that Cyclone Giri struck the coastline with winds of 175 km/h (110 mph ). Once overland, the cyclone rapidly decayed as convection dissipated. Despite having estimated winds of 150 km/h (90 mph ), the JTWC issued their final advisory on Giri just six hours after landfall. By early October 23, only scattered bursts of convection remained around the
