2024 Tropical Waves

[cycloneye]

Waves at 6/4/24 at 12z analysis.

An Atlantic Ocean tropical wave is along 26W, from 11N southward,
moving westward about 10 knots. Any close precipitation is related
to the monsoon trough or to the ITCZ.

An Atlantic Ocean tropical wave is along 39W, from 11N southward,
moving westward about 10 knots. Any close precipitation is related
to the ITCZ.

An Atlantic Ocean tropical wave is along 54W, from 13N southward,
moving westward about 10 knots. Any close precipitation is related
to the ITCZ.

The earlier central Caribbean Sea tropical wave that was close to
72W, at 04/0600 UTC, was eliminated from the map analysis. Most of
the moisture that was accompanying this feature is outside the
Caribbean Sea at this time.

The earlier western Caribbean Sea tropical wave that was close to
85W/86W, at 04/0600 UTC, was eliminated from the map analysis.
This wave has become caught up in the nearby NE-to-SW oriented
upper level trough.
