I wouldn't get too excited about a frontal wave with 40-50 kt SW winds aloft. Sure, there have been occasions where a sheared semi-tropical system has developed in such situations, but the chances for development (which would mean NHC issuing advisories) would appear to be quite low, perhaps 1% or less. And anything that does develop will zip to the NE across Cuba and out to sea. So nothing we in the U.S. should be the slightest bit concerned, with the possible exception of extreme south Florida, where there may be a little rain.

I agree this has about zero percent chance/

The major shear drop in the Carib and Atlantic should help devellopment for this system if it can organize a little.

Persistance is the key word with this.Give it a couple of days to see how it all evolves,or it weakens or it starts to organize.

Right now that wave isnt looking good but if you go to Jeff Masters lastest blog he say that the shear is breaking down and devlopment could happen next week with something.

CARIBBEAN SEA...
WEAK TRADEWINDS AGAIN DOMINATES THE CARIBBEAN. THE COLD FRONT THAT
MOVED OUT OF THE GULF NOW EXTENDS ACROSS CUBA NEAR 22N81W TO OVER
HONDURAS NEAR 15N84W. WITH THE BROAD UPPER RIDGE COVERING THE AREA E
OF THE FRONT...IS ANCHORED BY AN UPPER HIGH OFF THE COAST COLOMBIA
NEAR 12N73W WITH THE UPPER RIDGE EXTENDING ACROSS HISPANIOLA INTO
THE W/CENTRAL ATLC. THUS...SCATTERED MODERATE/STRONG CONVECTION HAS
DEVELOPED E OF THE FRONT FROM 72W-81W FROM OVER CENTRAL/SOUTH
AMERICA ACROSS W CUBA AND HAITI INTO THE W ATLC. THIS IS LEAVING THE
FAR W CARIBBEAN CLEAR AND DRY. THE UPPER TROUGH OVER THE CENTRAL
ATLC EXTENDS S INTO THE TROPICS INCLUDING THE E CARIBBEAN E OF 65W.
DRY AIR CONTINUES TO DOMINATE THE FAR E CARIBBEAN INCLUDING THE
LEEWARD ISLANDS EVEN WITH THE PRESENCE OF A TROPICAL WAVE.
Above is the 8 PM discussion from TPC.Nothing to open eyebrows reading from that paragrafh.
