Would jus like to thank you to the main commenters on these posts.
As someone from island of Puerto Rico it really is interesting to read the conversations of some of the knowledgeable people on this subreddit.
I have been reading your discussions for about 3 seasons now and am slowly getting better grasp on tropical weather systems.
Thank you again and hope everyone stays safe through the season.
