True but I’m really starting to have mixed signals as mid-level dry air and SAL seems to be making itself at home in the Atlantic this year. It could be one of those quantity over quality seasons with maybe a significant threat or two a lot like 2012.



THE CALENDAR JUST FLIPPED TO AUGUST 15 HOURS AGO

As I stated I’m well aware of that! :lol:

Everything struggled consistently in 2012 and almost served as a precursor to 2013 (not sure if there's any correlation though) where everything struggled to even form. Just about everything under-performed, especially during the peak, where this year everything that wants to form is forming and is often not only doing so against common reasoning, but over-performing the forecasts, outside of the MDR itself (but that's been the state of just about every season since 2010.)

I'm very much thinking at this point we get a 2000-esque season, albeit a stronger variant, as late July/early August is behaving like late August did and we're likely to have a lull (or decrease in frequency) for a few weeks, and as Isaias is demonstrating, with the TUTT further to the west.

If it does follow the same pattern (burst of activity in the Gulf/MDR, lull, followed by a gradual buildup of activity with another burst in the MDR) then what we saw at the end of September will most likely go the entire month and into October and that year was already a record (or near-record if it's since been broken) September in terms of named storms.

I’m thinking slightly more active version of 2000 where we exhaust the name list and potentially go Greek, but with only 8-10 hurricanes, and a few majors.

Maybe this will be Mother Nature’s way of making up for what’s been a heck of a year already.

It's still fairly early in the season, so Isaias struggling isn't a huge surprise. I think after the current 20/60 AOI which may become Josephine, we may see a lull in activity for 1-3 weeks before the "true" peak season begins in the last third of August.

:spam: :spam: :spam:

All in all just because Isaias is struggling even though it was forecast doesn’t mean the season will be weak. All the signs currently point towards extremely active and likely even hyperactive season, and so far mostly EVERYTHING has exceeded expectations and the models. This dry air in the Gulf is just poorly timed in time for August for people to start downcasting. :lol:

It sure doesn’t help that the models did poorly with Isaias. Not to mention it’s been a real pain in the butt to track!

Its kind of amazing how this year is doing the opposite of last year with the models--with a few exceptions (anything that becomes a Cat 5 is automatically an overachiever) everything last year was coming in much weaker than what the models predicted and several systems that should've rightfully formed and had near unanimous model support never did--in fact I remember after Dorian there were something like 3-4 storms predicted almost back to back in the MDR and only Gabrielle's wave actually formed (and struggled all the way)

On a side note it would've been interesting to see how everybody here would've been reacting as far as seasonal forecasts as Debby was sheared into nothing in late August 2000--outside of Alberto, we'd had that, two under-performing tropical storms, three depressions that failed to reach storm intensity, and literally nothing in July other than dry air--and not so much as a depression formed for the next two weeks until another 18 hour depression formed in the Gulf.

It appears likely, aside from Isaias and the current 20/60 AOI, that the Atlantic tropics will be fairly quiet through the first two weeks of August. However, recent EPS runs show a strong CCKW possibly reaching the basin around the third week of August, and climatology will become much more favorable for significant activity then. The last third of August frequently produces three named storms by itself.

The last 10-15 days of August are definitely enough to get 4, maybe even 5 named storms. I mentioned a couple of days ago that a lull in the first half of August will likely benefit an uptick in activity later in the month by giving the waters in the MDR, Caribbean, and Gulf time to rebound and warm up without being disturbed by TCs. If we go two to three weeks without any TC in the tropics, that means they’ll be locked and loaded for when activity does resume and climatology nears peak favorability. I’m thinking 1-2 majors towards the end of the month is a decent possibility.

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.

SST's aren't an issue right now or tomorrow.

Can't say I trust what the long range models are depicting for the 1st half of August.
Many times in the past two years it was more the mid-range outlooks that yielded an accurate representation real formation.

They’re definitely warm enough in the western Atlantic, but we haven’t reached the time of year when the northern MDR and north central Atlantic are consistently >26-27 C. Peak SSTs overall are still a few weeks away, and a lull in TC activity — meaning less disturbance of surface waters — will only help them warm up.

A relatively strong suppressed KW is entering the Atlantic right now, following the strong CCKW that helped spawn Isaias and TD 10.

I have August being quite active for the Atlantic. Maybe a break in activity for the first 10 days, but it's been far too easy for disturbances to spin up for there to be a significant lull during August.

Sure, we might see a lot of storms. But I don't think they'll be terribly strong. We may see 20 more 45 mph tropical storms moving north in the middle of the Atlantic. I don't call that activity.

MJO is spiraling the other way, the way it went in winter (thankfully then). Maritime Climate. NCEP has it 4-5-6-7 through the 15th. EC and others drop back to the circle. JMA goes into Phase 3. It's hard to say what's going to happen, but the Phase 4 to 5 is probably why there isn't enough juice to get Isaias cranking beyond a strong TS/Cat 1. Should be limited tropical activity after Isaias moves up and out for a week to week and a half. I'm not saying something can't form somewhere in the basin, but we aren't seeing any hyper phases at least for a while. Stay tuned.

Isaias might be a precursor of tracks to come.

What are you basing this on? We have yet to even reach the BEGINNING of the climatological spike in the tropical calendar. Come on, we need to do better in this thread. It's been quite unreadable lately. I feel like I have to pick the ticks off a dog to get to the good posts.
