Re: Watching a Few Areas in The Tropics

Looks an awful lot like the Bay of Campeche systems that we've seen this year, doesn't it? The actual LLC is just north of the Panamanian coastline and not too far from Nicaragua. Current steering pattern would tend to favor keeping it pretty much where it is, steered only by Beta drift (weak as it may be for such a small, low-latitude storm) and any sort of reorganization due to convective features. A trough off to the west of the storm isn't strong enough to hinder development or allow it to get caught up in the midst of the flow toward the NE -- not yet, at least -- while it is pretty much planted directly underneath a small-scalre upper level ridge. Creates a pretty favorable environment for development but doesn't foretell a lot of movement.

Best call is for a slow drift to the NW over the next couple of days; how strong it is then will play a role in whether or not it continues across central America or remains off-shore and ultimately recurves. As noted yesterday, it's one of those divergent solutions -- either across and toward the Pacific, or up and out to sea likely through Cuba and the Bahamas. Given current organizational trends, it'll probably get classified as our 26th depression tonight or early tomorrow and likely end up as Beta before too long. Biggest hindrance to development is going to be whether or not it gets closer to/moves over land. If so, it'll likely end up like the Bay of Campeche disturbances; if not, it's got a shot at something a little more, a la Stan. One to watch.

Wave near the Lesser Antilles has a shot, but needs to slow down first and become better organized. Largely just a mess of convection right now, but conditions should become a bit more favorable over the next day or two. As HF mentioned in the other thread, it'll likely end up relatively close to 90L/future Beta? at some point, making the ultimate forecast for both just a tad bit trickier. Not a sure bet to develop in the least, but worth watching.
