TROPICAL WAVE IN THE ERN TRPCL ATLC EXTENDS ALONG 15N28W TO
7N33W MOVING W AT 10-15 KT. SATELLITE IMAGERY AND SATELLITE
DERIVED WINDS INDICATE BROAD CYCLONIC FLOW IS AROUND THE WAVE
AXIS. A SLIGHT RIDGE OF MOISTURE WITH ENHANCED VALUES IS EVIDENT
IN TOTAL PRECIPITABLE WATER IMAGERY. SCATTERED MODERATE/ISOLATED
STRONG CONVECTION IS FROM 10N-14N BETWEEN 29W-33W.

Maybe,we should look more to this wave as it looks much better than 90L.

TROPICAL WAVE IS ANALYZED FROM 10N31W TO 17N29W MOVING W AT 10
KT. SATELLITE IMAGERY AND SATELLITE DERIVED WINDS INDICATE BROAD
CYCLONIC LOW-LEVEL FLOW IN THE VICINITY OF THE WAVE AXIS WHICH
REMAINS EMBEDDED WITHIN THE ITCZ AXIS. TOTAL PRECIPITABLE WATER
IMAGERY ALSO INDICATES A NORTHWARD EXTENSION OF LOW-LEVEL
MOISTURE TO 18N BETWEEN 27W-35W. WIDELY SCATTERED MODERATE
CONVECTION IS FROM 10N-14N BETWEEN 30W-35W.

Interestingly I think it was last nights ECM actually briefly tried to get something going with this wave in the 48-72hr mark, weakens quickly after that but worth watching out for!

Tropical wave is analyzed from 18n31w to 9n35w moving W at 20
kt. Satellite imagery and satellite derived winds indicate broad
cyclonic low-level flow in the vicinity of the wave axis which
remains embedded within the ITCZ axis. Total precipitable water
imagery also indicates a northward extension of low-level
moisture to 20n between 25w-40w. Widely scattered moderate
convection is from 9n-14n between 32w-39w.

They aren't saying there isn't any convection. They are saying there is no significant convection. There is a big difference...

A tropical wave is in the central tropical Atlc analyzed from
16n35w to 9n41w moving W at 10-15 kt. Satellite imagery and
satellite derived winds indicate broad cyclonic low-level flow
in the vicinity of the wave axis which remains embedded within
the ITCZ axis. This wave is embedded in a deep moisture surge
on total precipitable water imagery.

DAYS. RAINSHOWERS AND THUNDERSTORMS ARE FROM 14N TO 15N BETWEEN
40W AND 41W. ISOLATED MODERATE RAINSHOWERS ARE FROM 10N TO 15N
BETWEEN 40W AND 50W.

It isn't just you. An earlier ASCAT pass showed something fishy going on down there.

Im thinking and we call them fish when they dont affect any land areas. If this one is a "fish" it would have to start or pretty soon begin to drift more northwards as it would head towards the lesser Antilles, otherwise. :double:

A tropical wave approaching the Lesser Antilles is from 19n54w
to 9n56w moving W at 10-15 kt. Satellite imagery and
derived winds indicate broad cyclonic low-level flow in the
vicinity of the wave axis. This wave is also embedded within a
deep moisture surge on total precipitable water imagery. Widely
scattered moderate convection is from 9n-16n between 51w-58w.
