2 PM TWD:

A new Atlantic tropical wave is analyzed along 28W from 20N
southward. Scattered showers are noted from 05N to 10N between 24W
and 34W.

2 PM TWD:

An Atlantic tropical wave has an axis along 39W from 16N
southward, moving W at 10-15 kt. Scattered showers are noted from
05N to 10N between 34W and 40W.

southward, moving W at 10-15 kt. Scattered showers are noted
from 02N to 08N between 35W and 40W

Saw the rotation in the clouds earlier but naturally hoping it will dry out since there is ridging further west that would not favor recurve. I agree with the posters that suggested all the tropical activity in the Pacific is suppressing Atlantic activity. Probably a Madden-Julian Oscillation anomaly combined with dry air and a low latitude ITCZ?
Hoping for a quiet 10 day start to August, then maybe only one or two named storms before September.
I'm the only person that bet on one storm for August so not too confident with that guess.

8 AM TWD:

An Atlantic tropical wave has an axis along 42W, south of 16N,
moving W at 10-15 kt. No convection is noted with this wave at
this time.

8 AM TWD:

An Atlantic tropical wave has an axis along 32W south of 21N,
moving W at 15 kt. The wave is embedded in dry and dusty Saharan
Air Layer, inhibiting the development of showers and
thunderstorms.

2 PM TWD:

A third Atlantic tropical wave is near 45W from 16N southward and
moving W at 15 to 20 kt. Scattered moderate convection is noted
from 05N to 08N between 43W and 46W.

[cycloneye]

2 PM TWD:

Another Atlantic tropical wave is along 35W from 21N southward
and moving W near 15 kt. Scattered moderate convection is found
from 04N to 06N between 31W and 38W.

[cycloneye]

8 PM TWD:

Another Atlantic tropical wave is along 35W from 19N southward
and moving W near 15 kt. Scattered moderate convection is found
from 04N to 08N between 30W and 37W.

[cycloneye]

8 PM TWD:

A third Atlantic tropical wave is near 51W from 13N southward and
moving W at 15 to 20 kt. Scattered moderate convection is noted
inland and near the coast of French Guiana and Suriname.

8 PM TWD:

A third Atlantic tropical wave is near 51W from 13N southward and
moving W at 15 to 20 kt. Scattered moderate convection is noted
inland and near the coast of French Guiana and Suriname.

Seems like this wave will be too far south for any chance at development further west in the Caribbean.

An Atlantic Ocean tropical wave has an axis along 54W from 13N
southward, moving W at 10 kt. Scattered moderate convection is
noted near the coast of Suriname and Guyana, S of 08N between 55W
to 58W.

[cycloneye]

8 AM TWD:

An Atlantic Ocean tropical wave has an axis along 39W from 19N
southward, moving W at 10 kt. No convection is noted with the
wave at this time.

2 PM TWD:

Another Atlantic tropical wave is near 42W from 19N southward and
moving W at 15 to 20 kt. Scattered moderate convection is present
from 03N to 07N between 38W and 43W.

[cycloneye]

2 PM TWD:

A third Atlantic tropical wave is along 57W from 13N
southwestward across NW Guyana, and moving W near 20 kt.
Scattered showers and a few thunderstorms are noted from 06N to
10N between 52W and 59W, N of Guyana, Suriname and French Guiana.
This wave will reach the Windward Islands this evening and
slightly increase the chance of showers and thunderstorms

18z Surface Pressure Analysis has it practically in the same position:
