Cyclone Mocha, an extremely severe cyclonic storm has intensified over the past day and is about to make landfall in Asia. The storm is packing winds of around 150 mph (130 knots) sustained, which is equivalent to a strong Category 4 hurricane on a 1 to 5 scale. It is expected to reach the coast during midday or afternoon Sunday, between Cox's Bazar in Bangladesh and Myanmar. The anticipated landfall is presently near or north of Sittwe, Myanmar, which is about 50 miles south of the Myanmar-Bangladesh border. Evacuations of around half a million people are underway in the region, focused on northern Myanmar and southern Bangladesh. There are concerns that the cyclone could hit the world's largest refugee camp, Cox's Bazar, where close to a million people live in makeshift homes. The UN is doing what it can to protect these areas. Mocha may turn out to be the strongest storm to strike Myanmar since Nargis in 2008, which killed more than 100,000 in the country.
