Tropical 2019 Atlantic Hurricane Season & Model Discussion

I definitely wouldn't go to sleep on the wave trailing 96L either, a recent SCATSAT pass (fwiw) showed a pretty formidable low-mid level circulation and the wave axis is undoubtedly sharper and the wave envelope is smaller than 96L, making short-term tropical cyclogenesis more likely imho vs 96L. Thereafter it may be a different story.

12z EURO is a bit more organized with this wave then past runs.8FA4C964-097B-4408-8C32-2D953712484B.gif
 
96L and the wave behind it probably have an outside shot to do something east of the antilles before they are eventually shredded by the TUTT in the SW Atlantic or Caribbean graveyard, but meh. Subseasonal forcing will become very hostile to the Atlantic for the foreseeable future w/ most of the upward motion shifting into the Indian Ocean, Maritime Continent, & far western Pacific during the first half of August & creeping out into the Central Pacific later in the month (arguably an even more unfavorable juxtaposition). Tropical cyclogenesis, if any, the next 3 weeks or so will likely have to occur in the subtropics, Gulf of Mexico, or near the Yucatan &/or Bay of Campeche.

A small, but non-negligible number of EPS members are still biting on a tropical depression or weak tropical storm from either 96L or the wave behind it east of the Antilles thru 4-5 days. After that, zzzzz.

Strike GOM and its 5 "Likes", Webb ... ;)
 
So will this season ever get as active as we previously thought it would? When does it look like the pattern becomes favorable?
 
I criticize JB for being cold biased in the winter and tending to be a wx hyper in general. But to his credit, he’s been quite bearish about the current hurricane season.

In 2013, only 2 storms became hurricanes. Unfortunately, Mexico experienced 50 deaths from devastating flooding from tropical storms Barry, Fernand, and Ingrid. But we label 2013 as the "quietest season since 1994". Wind or water kills.
 
Instability continues to be much lower than average across the MDR.

Likely a result of the dust and hostile MJO pattern we have continued to have.

Now that we are in August though any tiny window of favorable pattern could produce a storm.

Not a question of “if” but rather “when”. F71F4797-A3E0-4356-91C5-37571CF0E160.gif

Here is a cool table from the NHC showing average dates of storms and intensities.

If models are correct in keeping the Atlantic quiet through mid August we could then claim the season as starting “slow”. But it only takes a few weeks of favorable conditions to quickly change that.

we're at that time of year where people think it'll never flip every year

and within 2-4 weeks it has for the past few years and never looked back

technically if Barry holds up as a hurricane in the postseason we're ahead of climo there
 
GFS showing pattern change around week 8/20, that lifts the monster High further north. I think it most likely calm until the pattern change.
 
Starting to think we may get into a setup more favorable for any system that develops to be directed closer to the US by late month into early september. Pattern looks like it might tilt to more of a western/ central us trough with a ridge in the east or off of the east coast

The energy looks more favorable for GOM or development close to the USA from mid to late August. MDR still looks really quiet even through the next 30 days.gfs_chi200_global_21.png

Yeah I'm watching the time frame around the 20th to maybe kick something up along one of the old fronts off of the coast. With the eastern trough possibly losing its influence and more of a ridge taking shape these festering areas could get going

That’ll be delightful for a cruise starting on 24th! ???

I Remember seeing the GFS not so long ago at the end of the run with a massive high off the coast to the north, with a weak low below it
Henry2326 posted it above. Too bad It couldn't go past 384 hrs, It looked It could make a direct hit into NC/VA. I remember those types of setup steered Florence. If we can get a wave or front to Develop during that timeframe. Like you mentioned we could be talking about some tropical and or subtropical storms.

A convectively coupled Kelvin Wave is being sniffed out by the EPS to pass thru the Atlantic basin ~8/20 and amplify the AEW at the tail end of August & beginning of September against climo.
 
Whats up with this blow up in the Bay of Campeche?

GFS continuing the pattern change week of 8/20 and dropping in 2 opportunities....so they might be picking up on the Kelvin wave too.Screenshot_20190807-074119.jpg
