The Atlantic’s eighth named storm of 2017, Tropical Storm Harvey, is en route to the Caribbean. Air Force Hurricane Hunters found that Harvey had gained a closed low-level circulation, with peak winds of around 40 mph, so the former Potential Tropical Cyclone 9 was upgraded to TS Harvey by the NOAA/NWS National Hurricane Center in its 5:00 pm EDT Thursday, [August 17] advisory. During the years 1966-2009, the average arrival date of the eighth storm of the Atlantic season was September 24—more than a month later than this year’s formation of Harvey—so 2017 is considerably more active than usual.
