Alright, I mentioned in my post last night that I would post the current oceanic heat content with some comparisons to the oceanic heat content at this point in March for some other seasons which ended up being active.
NOW 2020:

2017:

2010:

2005:

From what I can tell, 2010 seems to be about the closest match to the current heat content out in the Atlantic. I believe 2010 set a couple of record warm anomalies in the MDR region in the spring/early summer, it even beat out 2005, and the MDR was active that year, it was a very impressive season.
Now, other factors go into a season besides SST anomalies and the heat content that is available, but with heat content like this currently available, I believe it is quite possible it will continue to build, and we may end up seeing some pretty impressive warmth in the MDR during the hurricane season, and if you look at current SST anomalies, there already is.

On a quick side note, speaking of warm anomalies in the MDR, on a couple of occasions I’ve seen mention of the term Atlantic Nino. Currently along the equator between S. America and Africa, there are quite a few warm anomalies, does anyone know if this is an Atlantic Nino currently? I haven’t seen a lot of info on the subject, so I don’t know if there are any definitions for it, or qualifications that have to be met, or if this is just a loose term that hasn’t really been defined or given a lot of scientific merit.

I haven’t really set down numbers yet in my head, I’m watching other factors too and just waiting patiently to get past the spring predictability barrier, and I know that my numbers will probably change, possibly by quite a bit, once we get into May and we all start posting our numbers in the seasonal numbers thread. One idea I am starting to give more weight too though is the possibility of some pretty decent ACE generation out in the MDR this year. I think we have the potential setting up for some CV long-trackers, and with SSTs and heat content building like this in March, I think they will have a pretty high ceiling, maybe Irma or Isabel-like potential. NOTE: I am not forecasting another Irma or Isabel, just saying I think conditions may be setting up for a storm to potentially reach those kind of heights intensity-wise if all other factors come together in that storm’s favor.
I am really looking forward to when the seasonal thread opens up and everyone starts posting their thoughts and numbers, and I’m looking forward to passing the SPB. It’ll be interesting if forecasts start to flip once we get past that point.

Here’s the full globe view, and that is some very impressive warmth right now in the MDR. However, it is only March and those cold anomalies up by 50N could easily slide down the coast of Africa and make for a -AMO look by June or July. It remains to be seen whether this hurricane season will add insult to injury to an already devastating 2020, or if it’ll give us a break and stay inactive.

While 2005 makes for a decent analog, I wouldn't anticipate this season being a clone of the former.

Similarities
- Weak nino/warm neutral to start off the year
- Similar subsurface warm pool
- Warm MDR
- Warm Indian Ocean

Differences
- Negative PDO pattern is present in 2019, looks more positive in 2005
- As Paul Roundy pointed out on twitter in the below tweet, 2020's subsurface cold pool extends across the whole pacific, unlike 2005
- Although the MDR is warm, 2020 does not exhibit a classical +AMO pattern unlike 2005.
- 2020's Tropical Atlantic warmth is more equator focused
- 2020 also has a very warm GoM at the moment

Is that really a true El Niño pattern if there is rising motion over the Atlantic?

That doesn't look like a clear cut El Niño, that sinking extends quite far to the east, and there's no strong compensating rising motion. Plus, Africa being the driver here doesn't really hurt the Atlantic that much. This just more looks like a projection that puts the lid on a La Niña

Like the U.S. let alone anywhere in the Atlantic or worldwide needs an above average season, the COVID-19 pandemic is enough to deal with for this year!

Did he tweet it's a joke?

It doesnt look like an El Nino atmospheric setup but not exactly a La Nina as well.

All jokes aside, I’d gladly take a full blown El Niño season this year.

Barring something super natural occurring, the two opposite ENSO extremes (Strong El Nino/Strong La Nina) odd's of occurring by ASO are very low, especially for a strong El Nino. I think we should all take the time to be prepared for a long hurricane season. IMO We should all get prepared now as the present pandemic could make it harder to get supplies when a threat forms during the heart of hurricane season.

What is the JFM precipitable water value, and how can it influence activity in the Atlantic?

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

More precipitation, more waves come out of Africa that are the first seeds.

The April Euro seasonal update has above average rainfall in the MDR, Caribbean, and GOM.

Again if anyone has April euro precipitation forecast please message me. Think it’s quite telling if true and could very well be signaling a BIG season awaiting for the Atlantic.

Ok just took a look and the April euro precipitation maps for June,July,August for the Atlantic and all I can say is woah this is scary look coming from this model. If sst’s keep warning a hyperactive yr is almost a given. :eek:

Edit: Euro has been bone dry this time the last couple years and we've had average years.
