Miami Herald - Delta has exploded from a tropical storm to a Category 4 hurricane in the last two days, and the latest predictions show it could be nearly a Cat 5 by the time it crashes into the Yucatán Peninsula on Wednesday and remain a powerful Cat 3 by the time it reaches the northern Gulf Coast later this week.
"On average, Atlantic hurricanes are intensifying from a storm to Cat 3 now 20 hours faster than 25 years ago," tweeted Katharine Hayhoe, a climate scientist with Texas Tech University's Climate Center. She was referencing a 2012 study published in the American Geophysical Union.
