Re: ARABIAN SEA: INVEST 94A
Looks like a TD is forming/has formed near 7.8N/65.4E. I don't see any LLC west of 65E. Definite rotation east of 65E. Good banding. If it isn't a TD already then it will be soon.

Do you think it'll affect any landmasses?

EC & GFS indicate a landfall in Yemen in 8-9 days.

Yeah, you have to classify this.
As is often the case in the Arabian Sea though, dry air does lurk about.

Re: ARABIAN SEA: INVEST 94A
Low VWS area lies ahead just east of "the HORN" - must be the sweet spot for this system though I still expect this to weaken considerably before landfall.

fortunately, I do NOT have to wait for this to form a concentric eye as IMD will before they even call it a depression. I went ahead and called this a depression at 3Z

So it's not going to be like that system that formed earlier this summer (July?) but eventually dissipated?

unfortunately no. This could get quite intense as well. EC is taking this down to about 943mb before it weakens to about 986 at landfall as it rides along the coast for about 18 hours
Given this is a desert, this is a rain threat
