Departamento Meteorologico Aruba


Tropical Depression Eleven is centered near 13.0N 53.5W at
22/0900 UTC, or 440 nm (810 km) E of the Windward Islands,
moving W at 4 kt. A slow westward or west-northwestward
motion is expected during the next couple of days.
Maximum sustained wind speed is 30 kt with gusts to 40 kt.


The tropical wave has its axis along 39W/40W from 04N-16N
and is moving west at 10-15 kt. The wave corresponds nicely
with a maximum in TPW imagery. Model analyses depict an
associated 700 mb trough along 39W. Isolated showers are
near the wave axis. Little change is expected with this
wave over the next 24-48 hours.


A tropical wave is moving across the western Caribbean.
The eastern Pacific monsoon trough combined with diffluence
aloft is helping to induce scattered showers over portions
of Costa Rica and Panama. Plenty of moisture will persist
over the southwest Caribbean today. Otherwise, fresh to
strong winds prevail over the south-central Caribbean.
These winds will diminish across most of the basin by
Sunday night.
