Tropical Storm Edouard is centered near 39.0N 53.6W at 0900 UTC,
or 530 mi S of Cape Race Newfoundland, moving NE at 30 kt. Max
sustained wind speed is 35 kt with gusts to 45 kt. Edouard is

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

An eastern Atlantic tropical wave with an axis along 29W from
00N-20N, is moving west at 15-20 kt. Saharan dust is noted over
much of the eastern Atlantic, mainly from 13N to 22N east of 40W.
Due to this associated dry air scattered moderate convection is
confined near the monsoon trough from 03N to 08N between 17W
and 30W.

An eastern Atlantic tropical wave with axis along 50W from 04N-
19N, is moving west at 15-20 kt. Scattered moderate to strong
convection is noted from 09N-14N between 47W-55W.

A tropical wave in the eastern Caribbean extends along 67W from
05N-17N, moving west at 15 kt. No significant convection is
currently noted with this wave.


A weak high pressure ridge across the western Atlantic will maintain
fresh to strong trade winds in the South-Central Caribbean and the
local region through Thursday before increasing by Thursday night
and Friday. A tropical wave is moving in the Eastern Caribbean and
will pass through the local region Westward during the next 24 hours
inducing some widely scattered showers. A next, more active tropical
wave, is expected to reach the Eastern Caribbean by Tuesday. The chance
of further developing of this wave is very low, at 10%. Another round
of Saharan dust is expected during the next few days and will produce
slightly hazy skies. Persons with allergies and/or respiratory
illnesses should take the necessary precautions.
