Jet Blue #787 from JFK had difficult conditions today. Was scheduled to arrive at 5:46 and landed at 7:18. I noticed it arriving on Flightradar24 during the heavy downpour and thought I would watch the spray off the wet runway when it landed. When it got down to 825 feet on approach they aborted and went back up again. So I turned on the ATC audio feed and they aborted because of the westerly tail winds, so they circled and circled and circled.... for about an hour and forty five minutes before they safely landed. They said if conditions didn't improve they would have landed in San Juan. At least the passengers made it to their destination, but boy what a long ride!!
