Image: Defying forecasts, Tropical Cyclone Nargis regained strength, ultimately making landfall in the Irrawaddy River Delta region as a Category 4 monster on May 2, 2008, packing winds of 130 mph or more, according to estimates from the Joint Typhoon Warning Center.
By the time it reached Yangon, the nation's largest city, the still-strong Category 3 storm had killed thousands.
Cyclone Nargis was suddenly monstrous - The Hurricane unexpectedly reached Category 4 strength ahead of landfall in Myanmar. After slowly churning through the Bay of Bengal without gaining significant strength – and without forecasters predicting that it would – Tropical Cyclone Nargis suddenly intensified into a monstrous Category 4 storm with winds of up to 132 mph. The last prediction had been for Nargis to make landfall as a Category 1 or Category 2 storm.
