Second Tropical Wave of Season

We now have the second tropical wave off Africa. Satellite image and info below.

...THE ITCZ...
THE ITCZ AXIS IS CENTERED ALONG 2N10W 2N20W EQUATOR AT 34W THEN
1N43W INTO NE BRAZIL. CLUSTERS OF MODERATE/ISOLATED STRONG
CONVECTION COVER THE AREA FROM 3N TO 9N EAST OF 20W TO THE
AFRICAN COAST. A SFC TROUGH WAS ANALYZED IN THIS AREA ALONG
15W/16W ON THE 12Z SFC MAP. THERE SEEMS TO BE ENOUGH EVIDENCE TO
SUGGEST THAT THIS COULD BE A TROPICAL WAVE. SATELLITE IMAGERY
SHOWS A WELL DEFINED INVERTED V-PATTERN. THE HOVMOLLER DIAGRAM
ALSO INDICATES THE WWD PROPAGATION OF THIS SYSTEM DURING LAST
TWO DAYS...AND THE BAMAKO SOUNDING SHOWED THE PASSAGE OF THIS
TROUGH/WAVE BETWEEN APRIL 30 AND MAY 1ST. BASED ON THIS DATA AND
THE TIME OF THE YEAR...A TROPICAL WAVE WILL BE INTRODUCED ON THE
18Z MAP.
