| - Typhoon Krovanh (also known in the Philippines as Typhoon Marilyn), was a very catastrophic and intense typhoon, as well as being one of the strongest tropical cyclones ever recorded in history. Typhoon Krovanh decimated portions of Southeast Asia, particularly the Philippines and Taiwan during early to late September, 2015. It is considered as the deadliest and costliest tropical cyclone to hit the Philippines, until later beaten by Super Typhoon Choi-wan two months later. The Typhoon also struck a major metropolitan area two weeks after a major earthquake hit. Krovanh's predecessor can be traced back to an area of disturbed weather just west of the Marshall Islands on August 30, which then developed to a tropical depression two days later. It moved north to the northeast, and gradually shifted to the west in track. Gradually intensifying, Krovanh underwent a period of rapid deepening and explosively intensified from a Category 1 typhoon to a Category 4 super typhoon within 19 hours. Krovanh entered an area of moderate amounts of wind shear, and weakened to a Category 3 later that day, but Krovanh still attained a stadium effect. The next day, however, Krovanh re-intensified, and achieved it's title as a Category 5 super typhoon just to the south of Guam. Krovanh maintained it's intensity and explosively intensified further. It's pressure dropped a whopping 31 mbars in just 16 hours. As the typhoon slowed down and shifted to the north, Krovanh attained a peak intensity with winds of up to 175 knots (325 km/h; 200 mph) with a pressure reading of 869 millibars, thus making it the strongest typhoon in terms of pressure, until beaten by Choi-wan two months later. On 932 EDT, the relentless storm moved ashore over Baras, Catanduanes at peak intensity. Making it's second landfall at San Jose, Camarines Sur, and making several other landfalls over different parts of Luzon.
