The China Meteorological Administration said Rammasun was a super typhoon as it made landfall in Hainan – an island in the southernmost province of China – today (July 18, 2014) at around 6 a.m. EDT (1000 UTC). At that time, it had a sustained wind of 155 mph with gusts near 190 mph. Rammasun, also known as Glenda in the Philippines, struck that country earlier this week as a Category 3 storm.

The name Yamal means “the end of the world.” The cause of the crater, which was spotted by helicopters, is not yet known. A team of scientists has been sent to investigate the hole and is due to arrive at the scene on today. It is about 80 meters (87.5 yards) across.

In the middle of summer, you expect to see major heat waves hit parts of the United States with temperatures in the 90s and heat indices climbing over 100 degrees Fahrenheit. However, Mother Nature believes in switching things up.

A major dip in the jet stream across the eastern half of the United States and Canada will rush in extremely cool temperatures for this time of the year. Parts of the U.S. Midwest could see temperatures 10 to 20 degrees below average. There are rumors that the “polar vortex” is responsible for the cool weather this upcoming week. However, that’s not the case in this situation.
