We have had three powerful hurricanes over the past week. Hurricane Jose, which is taking more of a northerly track, Hurricane Katia, which slammed into Mexico's east coast, and of course Hurricane Irma which made its U.S. landfall in Florida.
The Atlantic Basin hurricane season starts up June 1st and runs until the end of November. The peak of the season, climatologically, is actually right now. The actual date is September 10th each season. So, seeing three hurricanes this month is not out of the question. The waters are very warm (hurricanes like 80°F+ water) plus thunderstorm disturbances rolling off the west coast of Africa, which is a huge birthplace for tropical systems.
Speaking of, there is a disturbance west of Africa now that has a 40% chance of forming into a tropical system in the next 48 hours. We'll have to wait and see what's in store as we move past the peak of the hurricane season.
