2022 Tropical Waves

[cycloneye]

Waves 17-18- 19 at 12:05 UTC discussion on 7/11/22.

An eastern Atlantic tropical wave has its axis along 34W from 07N
to 20N. It is moving westward at 10-15 kt. Convection with this
wave remains suppressed as African dust surrounds this wave.
Scattered moderate convection is limited to within 120 nm east of
the wave from 07N-10N and within 60 nm east of the wave from 07N-
09N.

An eastern Caribbean tropical wave has its axis along 66W south
of 19N, moving westward at 15-20 kt. No significant deep
convection is noted with this tropical wave.

A western Caribbean tropical wave has its axis along 82W south
of 21N to northern Panama. It is moving westward at 10-15 kt. This
wave is situated to the southeast of an upper-level low that is
near the western tip of Cuba. Divergence aloft between this low
and the tropical wave is helping to sustain scattered moderate to
isolated strong convection that is west of the wave axis from 12N
to 14N west of the wave to just inland Nicaragua. Similar
convection is along the coast of Honduras, north to near 18N.

between 45W-48W.

over Colombia.

A western Caribbean Sea tropical wave has its axis along 82W
south of 19N to across northern Panama and into the eastern
Pacific Ocean. It is moving westward near 15 kt. The monsoon
trough extends from northwestern Colombia near 10N75W to 11N81W
and westward to inland northern Costa Rica and into the eastern
Pacific Ocean. Numerous moderate to strong convection is along and
within 60 nm south of the trough between 78W-80W. Scattered

the trough west of the tropical wave to 83W.

Continent is along 19W, from 19N southward, moving W at 10-15 kt.

east of the wave axis along 19W. Scattered moderate convection is
from 09N to 12N between 19W and 24W. Convective activity with the
tropical wave is likely being enhanced by the Monsoon Trough.
