Unbelievable!!! Melissa just surpassed Hurricane Katrina (2005) as the 7TH MOST INTENSE Atlantic Hurricane in recorded history, with her pressure now down to 901 MBAR. Her torrid eye is reaching unprecedented levels of dryness. -3.94 C at one point. The CDO is shuddering with subzero cloud tops extending more than 50,000 ft into the atmosphere. It is absolutely terrifying to think about the fact that Jamaica is just hours away from getting hit by this HISTORIC monster of a storm. #hurricanemelis
