The broad circulation we’ve been watching in the SW Caribbean Sea, has been designated INVEST 93L
The NHC has maintained a MEDIUM (40%) probability for formation over the next 5 days.
NHC 5 DAY GTWO (LINKED)
Satellite loop imagery indicates a better defined area of low pressure, with clear counterclockwise rotation. Please forgive the “jumping” of the image, as I was not able to eliminate it:

Based on the last ATCF BTK information at 18Z (2:00 P.M. EDT), the following information was available on INVEST 91L:
MAX SUSTAINED WIND: 25 MPH
MOTION: WNW 5 – 6 MPH
PRESSURE: 1009 mb / 29.80 in
Maximum sustained winds were reported in the BTK report as 25 mph. Analysis of the ECMWF and GFS global models indicate pretty much no change in the forecast regarding sufficient moisture from the surface through the 500 mb levels, based on analysis this evening of surface to 500 mb RH vales and surface moisture based on forecast PWAT values. INVEST 93L is still under some 25 – 30 kts of wind shear this evening. The current SHIPS information indicates wind shear to remain in place, with a slight reduction in the 48 hour mark from 18Z this afternoon. However, based on analysis of the wind shear forecast from the ECMWF and GFS, wind shear is forecast to reduce, with a fairly favorable pattern developing over the Gulf of Honduras. SHIPS diagnostics concurs with a reduction in shear values to single digits. This is forecast to happen between 84 – 96 hours out in the period. Right now, this tends to correlate with the ECMWF and GFS shear forecast. Both models indicate an improved 200 mb streamline pattern with more of a radial type outflow pattern, just offset from the GFS forecast of the low center.
GFS AND ECMWF WIND SHEAR FORECAST
ECMWF AND GFS 200 MB STREAMLINE FORECAST
Based on the analyzed parameters, and given the close proximity to land, further development or organization should be slow to occur with INVEST 93L. Should INVEST 93L survive any land interaction as indicated by current track guidance, I believe at the moment, the best chance for development into a Tropical Depression should occur once the system moves over the Gulf of Honduras.
Information from the ATCF BTK report indicated the disturbance was moving very slowly at 285 degrees true or toward the WNW. Analysis of the current steering layer mean tends to indicate this, as winds over the disturbance and vicinity are mainly light and out of the west, and a weakness in the subtropical ridge is noted over northern Mexico (NW of the area 93L is embedded in). This would have the tendency to yield a WNW motion.
CURRENT STEERING LAYER MEAN
Based on analysis for forecast steering over the next 5 days, and current track guidance, INVEST 93L may take a more pronounced WNW track within the next 24 – 36 hours, or even possibly a NNW motion (which could be brought on by land interaction), then into the Gulf of Honduras. The majority of guidance models show this, and while I generally lean toward the consensus models, based on the forecast steering pattern, 93L could be on the southern portion of the track, just south of the TVCA. I would not focus much on the guidance models, as we have still a poorly organized low at the moment, and any center reformation, and any land interaction could result in a change in the track guidance forecast. You’ll note a large spread in the model guidance right now. For all intents and purposes however, this is the best scenario, based on initialization.
ATCF 18Z TRACK GUIDANCE
I will continue to monitor the area during the next 48 – 72 hours for any significant changes in the forecast, and for any further organization.
Elsewhere, Tropical Storm formation is not expected during the next 7 days.
