== Calculating ACE, and where's the info on gusts? == 

 I see Accumulated Cyclone Energy, but can you explain it to someone who barely recalls the summation symbol, so I can help add the ACE when doing an update? 

 Where's the info on current max gusts? Usually the public advisory just says "higher gusts", with an occasional example like "58mph", but the current Florence iinfobox says 115mph, and I haven't changed that statistic. 

 Also, why does the advisory say "MAXIMUM SUSTAINED WINDS REMAIN NEAR 90 MPH...150 KM/HR". At first I thought it was a typo, but the past several advisories say the same. Isn't 90mph approx 145 km/h?
