SAL Outbreak
|
A strong SAL outbreak should keep the Atlantic (east of the Caribbean Islands) quite for awhile.

Re: SAL Outbreak

Look at the bottom of the image where it says Saharan Air Layer Tracking Product. Great easterly winds (surface and aloft) sweep vast quantities of dust-filled dry air off the west coast of equatorial Africa. This air layer chokes off any convective activity and suppresses the development of tropical waves in the eastern Atlantic. At times, an outbreak can be so significant that African dust makes it westward all the way to the Pacific Ocean.

Looks like it may be waning. The last few disturbances as well as the current ( as of 7/11), and very nice looking one, has added a little moisture back.

From the MLB NWS evening Forecast Discussion: "LATE DAY HAZY CONDITIONS WERE OBSERVED ACROSS THE
AREA AND COORDINATION WITH WFO MIAMI INDICATES THIS IS DUE TO AN AREA OF
SAHARAN DUST ALOFT THAT HAS TRAVERSED THE OCEAN."
For the first time in quite awhile there are three strong waves on the African continent at about 10N.

I believe the SAL is preventing the deepening of an upper Low just to the NW of the Cape Verde Islands.
The low is the cyclonic area of white clouds in a reddish-brown tinted area.
The three systems, that ED mentioned in the above post, over the African Continent can be seen on the following 0 degree EUMETSAT airmass photo taken at 06Z or 2 AM EDT Friday.
