Tropical Storm Peter was centered near 19.1N 59.5W
at 20/0900 UTC or 390 km ENE of the northern Leeward
islands and moving WNW at 12kt. Maximum sustained
wind speed is 45 kt with gusts to 55 kt.

Tropical Storm Rose was near 15.9N 32.6W at 20/0900
UTC or 885 km W of the outermost Cape Verde Islands
and moving NNW near 13 kt. Maximum sustained wind
speed is 35 kt with gusts to 45 kt.


A tropical wave is in the Atlantic Ocean along the
west coast of Africa along 21W, from 02N to 20N,
moving west at around 10 kt. Scattered moderate
and isolated strong convection is noted from 06N
to 13N between the African Coast and 27W.


The weak ridge of the Atlantic high pressure system
will support gentle to moderate winds in the area,
with fresh winds in gusts. No significant cloud
development is expected due to low moisture levels
in the region and therefore, generally dry weather
will prevail.

Marine conditions: Calm seas are in place on the
protected sites with tranquil to moderate seas on
the south sites. Tranquil to moderate seas are in
place over the east to northwest coastal regions.
Seas are here in the range of 2 to 3, locally
4 feet.
