Pretty brief TWD on 97L at 8:00 p.m. Not much expected to happen until a couple of days from now possibly, which has been discussed earlier.
TROPICAL WAVE EXTENDS FROM 12N52W TO 19N51W MOVING W AT 15-20
KT. THE WAVE REMAINS LOW AMPLITUDE AND EMBEDDED IN THE ITCZ
REGION. SCATTERED MODERATE CONVECTION IS FROM 10N-14N BETWEEN
45W-59W.

NEVER, EVER SAY NEVER in the tropics and weather in general, and most importantly, with life itself!!

Don't expect much more than a rain maker, this is a classic example of the trade winds being force north by Cristobal and the High Pressure to its east. Once Cristobal leaves the area then conditions may improve.

Re: ATL: Ex INVEST 97L - Discussion
A tropical wave located about 600 miles east of the Lesser Antilles
continues to produce disorganized cloudiness and showers. This
system is now expected to move generally westward across the
Caribbean Sea with little development during the next few days.
However, environmental conditions could become favorable for some
development by early next week in the western Caribbean Sea or
southern Gulf of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...10 percent.

Re: ATL: Ex INVEST 97L - Discussion
I moved this thread from activestorms/invests forum to here as 97L is not active at this time. But as the 8 AM TWO says about development in Western Caribbean or Southern GOM, they may reactivate it in the coming days it will return to the invests forum.

Which leads me to an idea. Why don't we move threads for areas of disturbed weather when they become invests rather than locking them?

Here is a video by Levi Cowan about the tropics but explains a lot about what would occur with the wave/Ex 97L.

Re: ATL: Ex INVEST 97L - Discussion
From Dr Jeff Masters blog about ex 97L.
EX INVEST 97L' STILL WORTH WATCHING’
While yesterday’s Global model runs had forecast what was 97L to develop into a significant cyclone, the last few runs have completely backed away on this. However, most of the global models now forecast this elongated wave near the eastern CARIB to move across the CARIB towards the Yucatan over the weekend, with some models showing a small cyclone formation in the southern GOM next week.
There has been a dramatic increase in moisture both with the westbound wave and with a moisture plume from the deep (Equatorial) tropics in South America (SOAMER) that has been surging northward ahead of the wave for over 24 hours. Though wind shear is over 30Kts over much of the eastern CARIB (and will remain relatively high for the next few days) there is a somewhat anti-cyclonic flow developing between a small upper air Low/TROF in the west central CARIB and the approaching T.W. in the far eastern CARIB. This anti-cyclonic curvature of the high level wind field may develop further and move westward as the tropical wave traverses the CARIB over the next few days – and shear speeds may drop off during the weekend. Clearly a system worth monitoring over the coming days.

Re: ATL: Ex INVEST 97L - Discussion
A tropical wave located several hundred miles east of the Lesser
Antilles continues to produce disorganized cloudiness and showers.
This system is forecast to move generally westward across the
Caribbean Sea with little development during the next few days.
However, environmental conditions could become favorable for some
development by early next week in the western Caribbean Sea or
southern Gulf of Mexico.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...10 percent.

A tropical wave located over the eastern Caribbean Sea continues to
produce disorganized cloudiness and showers. Upper-level winds are
expected to remain unfavorable for development during the next
couple of days while the system moves across the eastern and central
Caribbean Sea. However, environmental conditions could become
conducive for some development when the system moves over the
northwestern Caribbean Sea on Sunday and into the southwestern Gulf
of Mexico early next week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
