Well i may not come up with such an educated answer(like the one you were looking for), but yes that wave and the wave behind it are in the tropical weather discussion in The NHC website. So we will probably see the model runs sometime this week.

A TROPICAL WAVE IS ALONG 59W/60W SOUTH OF 14N MOVING WEST
15 TO 20 KT. SCATTERED MODERATE TO STRONG SHOWERS AND
THUNDERSTORMS ARE FOUND FROM 12N TO 18N BETWEEN 59W AND 62W.
THIS WAVE SHOULD ENTER THE EASTERN CARIBBEAN SEA BY 1200 UTC
TODAY...BRINGING AN INCREASE IN SHOWERS AND THUNDERSTORMS.
A MODERATE TO STRONG SURGE IN THE TRADE WINDS WILL FOLLOW THIS
SYSTEM ACROSS THE EASTERN CARIBBEAN SEA
