Does that match up with that you have 1900? Took a fun little bit of programming to check the string for synoptic times.

Looks good, those are the numbers I have.

When was Emily 45kt? Advisory archive has 40.

14Z July 31st.

Slow start fast finish something unusual for the WPAC. Nothing usual.

Thanks to Gert,ACE in North Atlantic is near normal for August 16th.

Climo starts ramping up quickly though. Average ACE by date.

Lol hopefully Ace will be above average this year

[cycloneye]

Gert is gone but Harvey is up so let's see how much ACE it gets.North Atlantic is now above the average for August 17 that is 15 units.It has as of 21:00 UTC advisory 16.37

[cycloneye]

North Atlantic has fallen again behind the average ACE for August 19 and it looks like it will fall much more behind as things look to be quiet for now.

[1900hurricane]

Kenneth helped push the EPac back above the WPac, despite the presence of Hato over there.

[cycloneye]

Harvey should help the North Atlantic to be above average on ACE.

Here's what I have using best track data.

Avg ACE through 27 August for 1950-2016 is 23.24.

[euro6208]

The WPAC with Sanvu has taken the lead.

[cycloneye]

Let's see how much ACE Irma gets to run away from the average status to make the basin way above average.

[cycloneye]

RL3AO,do you have the latest data?

[cycloneye]

WPAC will get some ACE units from SANVU but will stay below average for 2017 so far.

[RL3AO]

The Atlantic has 27 units so far this year. The Atlantic averages 27 units during the next 14 days. Goes to show how active the peak of the season is.

[Alyono]

not that I give a you know what at this point given Harvey, but it is now clear this is not a 2013 repeat

[KWT]

The Atlantic has 27 units so far this year. The Atlantic averages 27 units during the next 14 days. Goes to show how active the peak of the season is.

Irma will produce all that and more on its own, regardless of whether a system forms from the BoC system or any follow up behind Irma.

Well worth watching how high this goes in the all time list, I'm pretty confident it'll go into the books as a top 10 ACE producer in the Atlantic. The right track could even challenge Ivan's record given Ivan didn't become a cat-2 till 50W.

[RL3AO]

If the 5 day NHC forecast verifies, it would add an additional 24 units or so of ACE. That means five days from now, Irma could have more ACE than the rest of the Atlantic season combined.
