That's the forecast for 96L, not the system to the west.

A tropical wave is moving across the east Tropical Atlantic west
of the Cape Verde Islands with axis from 18N32W to 10N30W, moving
west near 15 kt over the past 24 hours. The wave coincides with a
700 mb low/trough as depicted in the global models and is embedded
within a surge of moisture as seen on the SSMI Total Precipitable
Water imagery. Scattered moderate convection prevails along the
southern portion of the wave mainly south of 12N between 26W-32W.

SAL is keeping this tropical wave at bay this morning. European models is still persistent that this wave will start blossoming tomorrow into Saturday with convection as it approaches the Leeward Islands.

601 AM EDT THU JUL 28 2016

A tropical wave is in the central Atlantic extending from 10N-20N
with axis near 35W, moving at 15 kt within the last 24 hours.
Meteosat composite imagery show Saharan dry air and dust in the
wave environment. CIRA LPW imagery from the surface to 850 mb
confirms dry air intrusion in the wave environment, which is
keeping the wave devoid of convection.

Land interaction with the Greater Antilles is an issue on the latest GFS and Euro. Curious what sort of wind shear environment this will have to deal with as it passes through that area; latest GFS develops decent anticyclonic flow aloft that gets displaced as the wave gets tangled with Hispaniola.

BTW, the name for this thread needs to be updated, this tropical wave's axis as of 06z today is near 35W.

If this can go north or south of Hispaniola this may be something that has to be watched for a surprise tropical cyclone near The Bahamas and Florida and possibly the Carolinas

Bears watching. I posted this on the 96L thread but then read the coordinates again. Sorry for the error.

12Z GFS sends it right through the big Caribbean islands again without development.

This is most likely for our wave. Invest later today?

Yes but it looks like it tries to get going prior to Hispaniola. Have to thank those Greater Antilles and their mountainous terrain for keeping many systems at bay or weaker than they could have been for the U.S.

:uarrow: Now stronger too showing a hurricane.

Trend with models in the past 24hrs. has been south over the Greater Antilles and into the Gulf of Mexico with nothing much left to track, except the crazy CMC. :lol:

If it moves south of the mountains what stops it from ramping up? I heard wind shear would be low. Warm water? No shear? Possibly no land interaction? CMC doesn't seem so crazy to me if this does not go over the islands. 8-)

Not impressed...Ive yet to see the ECM show significant development from any of these waves. GFS brings pouch 06L which HH is set to investigate through plenty of land interaction. willing to bet that HH mission will more then likely be cancelled. I guess I can take some wannabe waves in late july. :spam:
