IMPRESSIVE pressure falls in Dakar, Senegal in Africa...

[Hyperstorm]

I said last night to keep an eye on the observations in Dakar, Senegal as it would be interesting to see what happened with that impressive area of low pressure about to exit the coast...

Well, the low pressure center is passing very close to Dakar and the pressures PLUMMETED! There were pressure falls of 4-5 mb in 24 hours! That's indicative of yet another VERY INTENSE tropical LOW about to exit the coast...

Although the system is very well-defined and strong, it is currently in a fairly high latitude 15-17N, and normally, these systems at this high latitude don't develop. Factors against it include cooler waters in its path. Another factor against it, is that the latitude of the SAL is right around 15-17N. Also, if Invest 99L develops significantly, outflow from its eastern quadrant should limit any development.

In any case, we're talking about yet another impressive monster to come off Africa in this powerful season...

What do you think of 99L? Is it becoming a depression???

Yes, I think it's VERY close to being upgraded to a tropical depression. There is a persistent area of deep convection near the presumed center, which is indicative of a tenacious little system for this time of year. It is currently located in somewhat cooler SSTs because of its high latitude, but once it continues moving westward it should approach even warmer waters.

Don't be surprised to see it become a depression as early as late this afternoon or evening...

so hyper
you don't see the System over Africa Developing is that what you're saying?

[Hyperstorm]

Conditions don't favor development that far north. If we were in September where SSTs were even warmer and there was less SAL, I would jump on it.

Having said that, it is a strong little system, and even if it doesn't develop over the E. Atlantic, it will continue to track westward and once it reaches the W. Atlantic or even the Caribbean it has a chance.

Right now, I'm mostly focused on Emily and Invest 99L...

[Duffy]

okay
just thought i would tell you, i read somewhere else that 99L is going to be a Fish

[Matt-hurricanewatcher]

Likely...But that way it can bomb into a cat5...

The problem is that you can't have three systems so close together. Remember last year Karl-Lisa-Disturbance, well the disturbance never made it because its it was so close to Lisa that Lisa absorbed. Lisa, on the other hand, struggled to survive behind Karl, so hard was the struggle that she almost died in the fight.

You can have three systems close together, but generally only TWO become strong. The other one stays rather weak throughout its lifetime. It is usually the one behind the first two.

As I said earlier, this happens because outflow from the preceding systems play a role in keeping the third one in check...

The wave that has just exited Africa has a circ center at about 12N, 13N at most.

It's not nearly as far North as 99L.
