12 Between 5 a.m. on Wednesday and 5 a.m. Thursday, Michaels pressure suddenly fell 40 mb and the maximum sustained winds increased by 63 mph, truly a remarkable case of rapid intensification

13 MICHAEL BECOMES CAT 3 HURRICANE: SEPT. 6

14 Michael, the 7 th hurricane of 2012 and located 980 miles west-southwest of the Azores and heading northeast at 7 mph, will likely weaken as it encounters colder waters..

19 SEPT. 12: EL NINO BEGINS AGAIN

20 Depending on how quickly El Niño develops, there could be a quick shutdown of tropical systems during the latter part of the Atlantic season and an extended season on the Pacific side.

21 TROPICAL STORM NADINE: SEPT. 12
