Ernesto as cat2/3 hurricane reaching E of Newfoundland on Monday according to NHC, followed by an 'interesting' variety of forecast tracks pointing at N Ireland/W Scotland.

Looks as if Japan may get a landfalling hurricane. But where is the action for the Atlantic?

Disturbance in place near usual spot by Cape Verde islands, interesting that since this morning the chance of development as gone up from 20% to 40%. It's showing on GFS and GEM charts in about 10 days' time.

So it seems the main reason the season has been so subdued is that the African easterly waves have been pushed north giving record amounts of rain over the Sahara desert while not providing the seeds to germinate tropical storms over the hurricane belt.

Slightly off topic, I also noticed some cyclonic thundery conditions over central Mediterranean lately. It'll be interesting to see what Autumn will bring in terms of Medicanes (can't find a thread on it).

But now a couple of Cape Verde disturbances setting out on their traditional track across the Atlantic, the leading one having potential for development, too soon to tell for the other. https://www.nhc.noaa.gov/?atlc

TD Six in Gulf of Mexico set to intensify rapidly and make landfall as hurricane just west of New Orleans on Wednesday, EDIT Now (Mon pm) TS Francine

A mid-Atlantic disturbance given 70% odds of developing into a major feature, presumably recurving to become the major mid-Atlantic storm shown on GFS Tue 24th - something like 940mb central pressure at that time

TD7 now declared west of Cape Verde Islands and expected to become TS Gordon shortly, but staying away from land. Possibly this is the one playing "Now you see me, now you don't" on the western side of the GFS charts for next week.


TS Bebinca passing close to Okinawa on Saturday and forecast to ramp up to a cat 4 before landfall in China.

Looking at latest GFS - I did notice several tropical storms/Hurricanes etc forming/developing looking at the charts in the Gulf/Caribbean next week, so one to keep an eye on as things could get interesting in those areas.

PTC 9 forecast by NHC to dodge past the western end of Cuba without landfall, and then strengthen into major hurricane (which would be called Helene) as it heads for the Florida panhandle, arriving Thursday.
