2017 ACE: NATL - 226.0 | EPAC - 98.2 | WPAC - 154.5 | NIO - 16.1

[1900hurricane]

Going back to 1970, the global calendar moth record for ACE in a single basin is 154.9 from September 2004 in the NAtl. If we can get a Cape Verde hurricane behind Jose, I wonder if we can challenge that too.

[Ptarmigan]

So if Irma stays at 160, we need Katia and Jose at 80 and 85 knots to get to #1.

I could see Jose and Katia as major hurricanes soon.

Guidance is hinting on a couple of more vigorous waves to come off Africa next week, with one potentially developing into another long-tracker. It looks very possible.

Irma weakening has prevented us taking the record right now, BUT Jose is going great guns at the moment and will be upgraded to 100kts, and wouldn't be shocked if this is upto 115kts soon enough which would put this into the record ballpark again providing Irma can stay A 5.

With Irma at 150 kt (may be a little high), Jose at 105 kt, and Katia at 75 kt, I have a total of 3.915 units of ACE for 00Z September 8. Looks like we managed to grab number one with the preliminary data at least.

Maybe the Atlantic will be KING worldwide and beat the WPAC for just the 4th time in history? Unless the WPAC goes quiet the rest of the year.

[znel52]

ACE ACE baby. Alright stop, collaborate and listen. Irma's back with a huge ACE addition. Jose is wound up tightly, he's a Category 4 daily and nightly. Will it ever stop? Yo, I don't know. Katia's in the Gulf and she's putting on a show. To the extreme too many storms to handle. The Atlantic Ocean is lit up like a candle.

Irma now closing in Matthew and Inez which will be making it the fifth highest ACE producer in the Atlantic later (0300 UTC) and Jose unexpectedly intensifies into a 150 mph (130 kts) category 4 major hurricane.

Glad you made the switch to the 1 minute side. JMA's 10 minute must have been confusing for you.

I updated the thread title for the Atlantic number since Luis is offline. Takes the lead for all basins

I don't think I've ever seen a season ramp up as quick as 2017 has since Harvey.

Nothing since 2004. To have this many systems intensify near land and most hit is ominous.
