...TROPICAL WAVES East of 70 West...

An Atlantic Ocean tropical wave is along 35W, from 18N southward,
moving W 15 knots. Dry and stable Saharan air dominates the wave
environment north of 14N. Scattered moderate to strong convection
is seen along and south of the monsoon trough from 05N to 10N
between 27W and 36W.

An Atlantic Ocean tropical wave is along 45W, from 15N southward,
moving westward 15 knots. Widely scattered moderate convection is
seen from 06.5N to 11.5N between 43W and 52W.

An Atlantic Ocean tropical wave is along 57W, from 17N southward,
moving westward 10 to 15 knots. Scattered moderate convection is
seen from 13N to 16.5N between 54W and 57W, while widely scattered
moderate convection is ahead of the wave from 09N to 13N between
57W and 60W.

Fresh to strong trade winds will prevail during this forecast period
increasing at times in gusts during the weekend. Limited moisture is
inhibiting significant cloud development in the local region. However,
a tropical wave near 57W will approach the Eastern Caribbean late today
into Friday. This will induce moisture and likely some shower activity
during the early weekend.
