Another Invest? (93L?)
From Jeff Masters:

Tropical wave approaching the Lesser Antilles
A tropical wave approaching the southern and central Lesser Antilles islands will bring showers and gusty winds to the islands Tuesday. Wind shear has dropped to 5-10 knots over the wave, and there is some potential for it to develop as it moves west to west-northwest into the Caribbean Sea.

See what you all can dig up on this one too!

Sheesh, are we making up for a slow season start, or what?

Not finding much info on this area. The Tropical Surface Analysis doesn't mark it as a wave. Looking at the WV loop the area doesn't seem to have any circulation at the moment.

The closest mention of this was in the NHC's Tropical discussion at 8Pm EDT.

DRY...SOMEWHAT STABLE AIR COVERS THE W ATLC W OF 68W
WITH SOME LOW LEVEL ISOLATED SHOWERS/THUNDERSTORMS BROUGHT IN BY MODERATE EASTERLY SURFACE FLOW.

This is all I found in the discussion for the one marked 93L:


TROPICAL WAVES...
TROPICAL WAVE IS ALONG 60W/61W S OF 29N MOVING W 15-20 KT. VERY
LARGE AMPLITUDE WAVE WITH UPPER LEVEL WINDS EXPECTED TO
GRADUALLY BECOME MORE FAVORABLE FOR DEVELOPMENT DURING THE NEXT
COUPLE OF DAYS. SCATTERED SHOWERS/ISOLATED THUNDERSTORMS ARE
FROM 19N-26N BETWEEN 50W-62W AND S OF 15N TO INLAND OVER SOUTH
AMERICA BETWEEN 55W-63W INCLUDING THE WINDWARD ISLANDS.

Wtnt02 Kngu 201600z
Subj/tropical Cyclone Formation Alert 201600z Aug 07//
Rmks/
1. Formation Of A Significant Tropical Cyclone Is Possible Within
100 Nm Either Side Of A Line From 22.3n 54.7w To 27.0n 65.8w
Within The Next 12 To 24 Hours. Available Data Does Not Justify
Issuance Of Numbered Tropical Cyclone Warnings At This Time.
2. A Low Pressure Center Located Near 22.3n 54.7w Has Formed
Beneath Intense Convective Activity. Wind Shear Has Been
Analyzed At 5 To 10 Knots With A Central Pressure Of 1009mb.
The Convection Associated With This System Is Still Disorganzied.
However, As This System Moves Into Weak Wind Shear And Warm Sea
Surface Temperatures Downstream, Tropical Cyclone Development Will Be
Enhanced Over The Next 24 To 48 Hours.
3. This Alert Will Be Reissued, Upgraded To Warning Or Cancelled By 211600z.

Interesting last night, but tonight it looks to be more scattered in nature and not more focused on one big blob like last night. Wind shear running 20 knts to the North and South, not sure what this system will do for right now so I am going to give it some more time before I say it is going to develop.

The CMC seems to put this into the lesser antilles at 126hr as a small deression.

Let's try this link on the CMC
