Tropical Storm “Danny” churning in Atlantic (8-19-15, morning)

Tropical Storm Danny continues to churn in the Atlantic.

However, it is looking a bit less “healthy” when compared to Tuesday.

I suspect it is feeling the affects of some dry/stable air that has been just to it’s north. This air originates over Africa and is called the “Saharan Air Layer.” (SAL)

“Danny” still has an inner core… as shown on the microwave satellite imagery.
