ATL: Ex INVEST 92L - Discussion

Re: ATL: INVEST 92L - Discussion
Convection may not be pretty at the moment, but looks really good on WV in the sense it is pushing away dry air and has a strong outflow / anticyclone signature.

If invest 92l and 93l form at the same time, could they have the fujiiwhara effect of each other? Or will one absorb another?

Yep, you saw correctly. That's why I was saying, that's one scary looking map!!
I can't even imagine how crazy this board would be if that came to pass.
Yikes, I know I'd be glued to the computer and going without sleep.

So fat 92l is behaving as expected. I did not expect development due to dry air and dust across the MDR as mentioned this past weekend.
Development chances do increase once it gets farther west past 55W but it depends on 93l.
93l has a better chance since there will be less dust and dry air as 92l is clearing that out for it.

not doing to well this morning at all... its becoming quite elongated. and dry air and easterly shear seems to have killed the convection.

Easterly shear?,and it's moving at only 10 to 15mph

Re: ATL: INVEST 92L - Discussion
Again, just like Emily, core gets compressed during the day which puts a lid on development and maintains 92L as a wave.
If this continues, the forecasted recurve could occur latter in time and further west.

It is unlikely that they will simultaneously be strong enough to exhibit a meaningful fujiiwhara interaction.

Could be today's bullish model support...GFS, CMC, and Euro all develop this well before 93L and in the next couple of days. Only thing I can think of.
