I think I've seen key messages on Twitter before for something that hasn't developed. I thought maybe the outlook itself was formatted that way too, but it isn't. So if I saw it then it must have been on Twitter. I can't remember for what.

Locally, they have been talking about how there could be a lot of beach erosion on the east coast of Florida.

GFS does some kind of variation of hitting the east coast of Florida and then turning back over Florida if it makes it into the Gulf. Usually something like this takes time to develop, but we'll see.

Putting out the key messages did seem a little early, but there could be a rip current threat in advance so that might be why they did. It seems like the time they did that before it might have been something that was to develop more significantly. But this time of year people might not be paying attention, especially when it comes to rip currents, and they want to warn people in advance.




Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sat Nov 5 2022

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical
Depression Lisa, located over the southwestern Gulf of Mexico.

1. Central Subtropical Atlantic:
A broad area of showers and a few thunderstorms located several
hundred miles east of Bermuda is associated with an non-tropical
area of low pressure. Recent satellite wind data shows that the
circulation has become somewhat better defined, and addition slow
tropical or subtropical development of this disturbance is possible
during the next two to three days. After that time, the system is
forecast to encounter stronger upper-level winds and further
development is not anticipated.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

2. Southwestern Atlantic:
A large non-tropical low pressure system is expected to develop
across the northeastern Caribbean Sea and southwestern Atlantic by
the latter part of the weekend. The system is initially expected to
be very broad and disorganized. However, it could begin to acquire
subtropical or tropical characteristics during the early part of
next week, and a subtropical or tropical depression could form
during the early to middle portion of next week while the system
moves generally westward to west-northwestward over the southwestern
Atlantic. Regardless of development, there is an increasing risk of
coastal flooding, gale-force winds, heavy rainfall, rough surf, and
beach erosion along much of the southeastern United States coast,
the Florida east coast, and portions of the central and northwestern
Bahamas during the early to middle part of next week.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...medium...60 percent.
