The broad area of low pressure across the Yucan we have been tracking for a few days is close to entering the Bay of Campeche and is starting to show signs of improvement along with some hints that conditions for the development of a quick TD or perhaps a named system could be rising. In fact, EURO ensemble implied development probabilities are nearing 50-50. As such, we are now starting a Lounge on this disturbance, recently Invest-tagged 91L.

This is primarily an eastern Mexico concern for the potential of some inland flooding and perhaps some challenging boating conditions.

Invest 91L has become TD TWO with today's 4PM NHC Advisory and the title has been updated accordingly.
