Good day to everyone!
As stated yesterday, I have posted my final update on Edouard.
An area of disturbed weather is located just off the U.S. east coast, east of the GA/SC area. This is associated with a frontal trof, and a developing surface low along the stationary portion of the front. Upper level winds are not conducive for any development, and the wind shear forecast indicates upper level wind will remain unfavorable for development. This should remain baroclinic in nature, and will be moving off to the NE along the deep layer trof.
The tropical wave that was behind Edouard, is now located NE of the Lesser Antilles. Convection has increased over the past few hours, however upper level winds are unfavorable for development, and are forecast t remain unfavorable for the next 60-72 hours. Based on current and forecast steering maps, this wave should begin to move toward the NW soon, and should follow through the weakness that Edouard is embedded in.
The disturbed weather I had been monitoring in the CATL which had a low associated with it, has become more diffuse, and is a very broad circulation centered near 10N;38W. Upper level winds are not conducive for development.
A tropical wave is entering the far eastern Atlantic ocean, just off the African coast. Based on the most current satellite images, this area appears to have some organization to it.
Analysis of the wind shear product from CIMSS, over the EATL, indicates an upper level anticyclone is established over this wave. Based on the current wind shear forecast, upper level winds should remain favorable for some slow development during the next 60-72 hours, before a slight increase in westerly shear occurs.
This wave is moving toward the west at the moment, and analysis of forecast steering layers maps indicates this may continue toward the west over the next 72-96 hours. Forecast steering was somewhat difficult to determine this morning, as the wave just does show up in the streamlines. However, there appears to be another wave that comes in right behind, and the steering models take it on an immediate recurve. Given the very close proximity, it is not clear whether or not this current wave is the one the models are re-curving right away, or a totally different system. Regardless, I will continue to monitor this wave during the next 72 hours for any significant changes and for development. I would not be surprised to see this be designated INVEST 95L possibly in about 24 hours.
Elsewhere, analysis of the global models still shows the GFS being consistent in development beginning over the Gulf of Honduras in about 9 days, with the low then moving across the Yucatan peninsula and into the southern GOMEX. Currently, the solution indicates a strong tropical storm, to minimal Category 1 hurricane in the central GOMEX near 26.0N. Albeit the GFS has been consistent in this for the past few runs, the solution is not written in stone. However, I cannot rule this out 100% as of yet, as with the premise of rising 500 mb height anomalies over North America, pressures should lower over the GOMEX. The GFS wind shear forecast is still consistent in indicating a rather large upper level anticyclone becoming established over the Yucatan peninsula in about 10-12 days, then covering the entire GOMEX afterward. I will be monitoring this over the next 8-10 days for more consistency, and especially for model agreement.
