July 13th, 2020 Tropical Weather Discussion


In this video, forecaster Jack Sillin discusses the forecast for tropical cyclone activity in the Atlantic during the week of 7/13-7/20. Topics of discussion include a possible high-latitude subtropical cyclone, an update on the Saharan Air Layer, and why the Main Development Region will remain hostile to development through Mid-July even as the SAL retreats.

Today’s discussion referenced two blog posts which you might find useful.
What is the SAL and why does it inhibit tropical cyclone development
What are tropical waves and why do they form in Africa
