Currently, I am watching four areas over the next ten days. Not all will develop, but they seem worth a casual eye.
1. Current Atlantic Lemon
This lead wave crossed into the Atlantic this weekend, and while it isn't terribly active convectively, it has a nice moisture envelope that could serve it well as it plows through a SAL plume in the central Atlantic. Any development of this one IMO would happen after about 60W, the Antilles vicinity. The guidance has a weak signal for development, in large part because of the uncertainty of the environment in the western Atlantic.
2. Follow up Atlantic Wave
A second robust wave is expected to leave the African coast in 5-7 days and at least right now, it looks like it'll have a lot going for it with regard to environment. First, it's likely to come off the coast further south, into a better moisture and SST environment. Second, it'll be trailing the first wave closely enough where SAL shouldn't (famous last words) be as much of an issue. Third, it'll be coming off as the MJO amplifies and CCKW passes, which should enhance convection. This one has potential to be a long tracker, but it's just potential for now.
3. Caribbean/Gulf Wave
There's a light but consistent signal on the ensembles that a wave in the Caribbean will traverse into either the Gulf or BOC next weekend.
4. Offshore East Coast Low
This one wouldn't be a threat to land based on current guidance, but there's a consistent signal on the Euro/GFS operational guidance that a wave of low pressure develops either off the East Coast or in the Central Atlantic the last few days of August before heading further out to sea and intensifying.
