TWD: Atlantic-
...TROPICAL WAVES...

A TROPICAL WAVE IS ALONG 40W S OF 10N MOVING W 10-15 KT. SHORTWAVE IR IMAGES SHOW A FAINT APEX OR WEAK INVERTED V PATTERN IN THE LOW-LEVEL CLOUDS. HOWEVER...MOST OF THE SCATTERED SHOWERS AND TSTMS ARE LINEAR IN STRUCTURE AND EMBEDDED WITHIN THE ITCZ WITHIN 300 NM EITHER SIDE OF THE AXIS.

A TROPICAL WAVE IS IN THE E CARIBBEAN ALONG 62W S OF 14N ESTIMATED TO BE MOVING W 10-15 KT. THIS WAVE MAY BE ADJUSTED W TO NEAR 65W ON THE 06Z MAP BASED ON A MOISTURE BULGE EVIDENT ON THE MIMIC TPW ANIMATION. THAT POSITION WOULD ALSO PLACE THE WAVE AXIS IN THE VICINITY OF SCATTERED TO NUMEROUS CONVECTION ...HOWEVER IT IS DIFFICULT TO DETERMINE HOW MUCH OF THIS ACTIVITY IS CONTRIBUTED TO THE WAVE.

EPacific-
...TROPICAL WAVES...

A TROPICAL WAVE IS LOCATED ALONG 90W FROM 05N TO 10N AND IS MOVING W ABOUT 10 KT. THE LATEST INFRARED SATELLITE IMAGERY INDICATES BROAD CYCLONIC TURNING WITHIN FIVE TO SIX DEGREES EITHER SIDE OF THE WAVE AXIS BUT MINIMAL CONVECTION.
