Tropical Update Tuesday 8-28-18, 5 pm.

8/28/2018

 
Good afternoon.

FYI below average water temperatures in the Eastern Atlantic and abundant Saharan dust over the Eastern and Central Atlantic as well as the Eastern Caribbean continue to suppress tropical activity.

Below is the current Saharan Air Layer Analysis. (SAL)
Yellows, oranges and reds are Saharan dust which as it sinks through the atmosphere, suppresses convection. It is also associated with dry air.

So far so good, however above average water temperatures in the Gulf of Mexico and the Bahamas will make these areas to watch. See bottom chart of current sea surface temperatures (SSTs).

Matt.
