Despite the 12Z Euro being much weaker, the more reliable ensembles (12Z EPS) are still quite active and still are heavily favoring either near or offshore the US E coast with just a couple of members with a TC in the E GOM.
Got thatvon the plots image or is that not out yet?

1. 12Z EPS is out on Pivotal.

2. Though not one of top 5 most followed globals, the JMA, which along with the ICON was best with Beryl's track in the W GOM, has a TC for the first time with it in the NW Bahamas moving NNW (TD at 1013 mb). Thus, counting this, that means 3 in GOM (ICON/GFS/CMC) and 3 in SW Atlantic (UKMET/Euro/JMA). So, this run has a TC for the first time on the JMA, UKMET, and ICON.
 
August hurricane 1970

A tropical depression developed off the west coast of Africa on August 7, with organized convection and banding features. A day later, the depression passed south of Cabo Verde as it moved across the tropical Atlantic. On August 10, it intensified into a tropical storm, after the thunderstorms became more concentrated. However, a Hurricane Hunters flight two days later observed a weak system, suggesting the storm weakened back to a tropical depression. While approaching the Lesser Antilles, the depression turned to the northwest and re-intensified back into a tropical storm, with hurricane-force wind gusts north of the center. Late on August 14, the circulation opened into a trough. On August 15, a circulation reformed, and the system became a tropical depression again as it bypassed the eastern Bahamas. A day later, the system re-intensified into a compact tropical storm while turning northward. On August 17, the storm made landfalls along the Outer Banks of North Carolina, first on Atlantic Beach and later at Rodanthe. As the storm accelerated northeastward, it intensified into a hurricane, with peak winds of 80 mph (130 km/h), based on the well-defined eye and a report from a nearby ship. On August 18, the system became extratropical south of Newfoundland, and subsequently it slowed and shifted its track back to the sou
 
Similar GFS

Big difference is it holds together enough to develop alomg the NC coast.

Possibly becoming a hurricane with a big high to the north.

I know this is a weather board and that’s what is discussed. That said, and I say it during the winter, I don’t see the point in the highs and lows of individual long range model run reactions. A signal has been shown, the conditions could be favorable but no one knows what’s going to happen. The models are going to flip back and forth until there is better data in a closer timeframe. Peak is still like 5 weeks away.

For a hyper active season this is a letdown so far. GFS up to aug 14. At least the GFS shows the east pac calming down.

06GFS has nothing but it has the East pac active once again. If that is right things will be delayed even longer

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Jul 29 2024

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

1. Near the Leeward Islands and Greater Antilles:
An area of disturbed weather over the central tropical Atlantic
Ocean is expected to interact with an approaching tropical wave
during the next couple of days. Environmental conditions are
forecast to become conducive for some development thereafter, and a
tropical depression could form later this week while the system is
in the vicinity of the Greater Antilles or the Bahamas.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...50 percent.
 
1) 12Z UKMET: still has a TD though not as strong as the 0Z’s TS that had skimmed the SE FL coast at Palm Beach. The new run delays TCG til it is 50 miles NE of Cape Canaveral. It then moves NE to 150 miles E of Amelia Island, FL:

————————-

2) 12Z CMC is further E and much weaker with just a weak low over SE FL/NW Bahamas. But then it gets stronger as it moves NE offshore NC and becomes a TS moving further OTS.
