Tropical Weather Outlook

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A tropical wave is forecast to emerge off the west coast of Africa
by late Thursday, and then move westward at around 15 mph for the
next several days thereafter. Environmental conditions are expected
to gradually become more conducive for some development to occur by
early next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

They need something to update regularly or they'll get too bored just like the rest of us :lol:

I don't think NHC just added this to the TWO because they were bored. Models may not do much of anything to this wave right now, but it will be interesting to see if they latch on over the coming days. It's late August now - the MDR is going to have to wake up soon. There will likely be a couple waves behind this one to watch as well that may have a better shot.

That's a bad look with a system in the Bahamas organizing on Sept.1 and a big ridge over the Eastern CONUS.
