Don't you ever sleep, cycloneye? ;-)

I see the NHC declared this wave as 98L, but development chances look pretty low. As we've seen, most invests never develop. And earlier or later in the season, such invests have even a lower chance of developing. But about the only place semi-favorable for development is the southern Gulf of Mexico. Development chances slim, but not completely out of the question. I'd ignore the BAM models and look at the dynamic models which take the disturbance into the SW Gulf by Tuesday then northeastward toward the northern Gulf Coast by next Thursday. The farther north it tracks, the stronger the upper-level winds (i.e., the greater the wind shear), though.

Next one is up! Finally, first chance at a storm since September.

NRL still doesn't have any imagery up.

Interesting pattern. Boundary between maritime tropical and drier air over south florida. Yesterday showers were moving both NE and SW in the straits. There's a bit of cyclonic spin south of Puerto Rico, don't know if that's along a tropical wave or UL. The NCEP fronts show the low right at the Yucatan with the convection farther north almost in the yucatan channel now.

from 830 TWD:
TROPICAL WAVE IS ALONG 75W S OF 18N MOVING W NEAR 10-15 KT. WELL
DEFINED LOW LEVEL INVERTED-V CURVATURE IS OBSERVED WITH A
POSSIBLE LOW LEVEL CENTER BEGINNING TO FORM NEAR 13N. SCATTERED
MODERATE/STRONG CONVECTION IS W OF THE WAVE DUE TO STRONG
EASTERLY UPPER LEVEL WINDS LOCATED FROM 12N-15N BETWEEN 76W-79W.

good call vortex on saying this would
be the one to watch.

This with favorable conditions and low shear
and high heat content waters has a chance
of becoming a tropical depression.

looks like a possible closed surface circulation, but exposed. Some easterly shear perhaps

Show it well here, but winds around the center are too weak:

LATCUR = 13.3N LONCUR = 76.5W DIRCUR = 280DEG SPDCUR = 13KT
LATM12 = 13.0N LONM12 = 73.9W DIRM12 = 279DEG SPDM12 = 13KT
LATM24 = 12.6N LONM24 = 71.0W


They haved been tracking the low for more than 24 hours.

Just a weak swirl for the low center displaced east of the convection near 13.5N/76.5W. Observations indicate winds 5-10 kts in the region. Strong NE wind shear dominates. Development chances about zero in the Caribbean. May be a slight chance of development if/when it reaches the SW Gulf Tuesday.

cycloneye,

We've been tracking it for at least 6 days as a tropical wave in the central Atlantic Oct. 8th-9th. But there hasn't been any evident low-level turning until now.

I'm not sure why this is an invest. NHC doesn't mention it and it looks like nothing but a strong wave heavily sheared from the NE as Wxman says --- it will more than likely crash into Central America.

Next please. Still waiting for a real invest. It has been a while.

Don't lose hope gatorcane...wxman57 says once it merges
with 94l the steering takes it into the GOM
and then some rain may finally come to
the drought stricken southeast.

Regardless of development the rain would be nice
over the drought areas especially georgia.
