From what we've seen for the past 2 months, the 2017 has done the opposite of most expectations. All named storms from Franklin until Ophelia, the easternmost major, have been hurricanes. Monthly ACE for September (175) surpassed 2004's record of 155. 2 if not 3 category 5's (Irma, Maria and possibly Jose) formed within a span of a month. A record three *major* hurricanes racked up over 40 ACE, higher than several seasonal totals each. Harvey broke the major hurricane drought for the entire US and drenched Texas with over 50" of rainfall. Afterwards, Irma breaks the major hurricane drought for Florida and becomes the strongest since Charley, striking a similar area. Lastly, Maria becomes the third major hurricane impact for the US, a record third Category 4 actually, with it being the strongest for Puerto Rico for decades and becoming their costliest natural disaster ever.
Tally as of late is 15/10/6 with an ACE of 226. Nearly identical to 2004.
