Still Small Chance Of Development, But Notable For Mid-October
BOCA RATON, FL (BocaNewsNow.com) — There is just a small chance that the yellow X above amounts to anything of concern for South Florida, but it is notable that yet another system is moving towards the state as we approach mid-October. The National Hurricane Center says there’s just a 20 percent chance that the system grows. We always note: the oval you see above is the area where a storm or system may develop, it is not a cone.
While forecasters keep their eyes on the system, we present to you the tropical outlook for Tuesday evening:

Scattered moderate convection is along the wave from 04N-16N and east of 21W. An Atlantic tropical wave has an axis along 43W from 02N-15N, moving W at 10-15 kt.
