The best place to go for an MJO update is the weekly MJO update link here:

http://www.cpc.ncep.noaa.gov/products/p ... update.ppt

You'll need PowerPoint to view it. Basically, there's no sign of a true MJO for the next few weeks and probably not through the first week of September. It's weak and in the Asian region. Typically, an MJO signal takes a good 30 days to reach from there to the East Pacific. But since this one is weak, it probably won't make it. Shear, however, is steadily falling across the Tropics.
Ok. Thanks, Wxman57.

ALTHOUGH THE AREA OF CLOUDINESS AND THUNDERSTORMS OVER THE
NORTHWESTERN CARIBBEAN SEA ASSOCIATED WITH A TROPICAL WAVE IS
SHOWING SOME ORGANIZATION ON SATELLITE...PRESSURES ARE NOT FALLING
AND THERE ARE NO SIGNS OF A DEVELOPING SURFACE CIRCULATION. THIS
SYSTEM COULD GAIN SOME ADDITIONAL ORGANIZATION BEFORE MOVING OVER
THE YUCATAN PENINSULA AND BELIZE ON SATURDAY. THERE IS A LOW
CHANCE...10 PERCENT...OF THIS SYSTEM BECOMING A TROPICAL CYCLONE
DURING THE NEXT 48 HOURS.

A TROPICAL WAVE NEAR THE YUCATAN PENINSULA IS PRODUCING DISORGANIZED
SHOWERS AND THUNDERSTORMS AS IT MOVES WEST-NORTHWESTWARD AT ABOUT 15
MPH. DEVELOPMENT OF THIS SYSTEM IS NOR EXPECTED DUE TO PROXIMITY
TO LAND. THERE IS A LOW CHANCE...NEAR 0 PERCENT...OF THIS SYSTEM
BECOMING A TROPICAL CYCLONE DURING THE NEXT 48 HOURS.

Unlike Colin, this system pretty much has one route. Mexico will be it's last stop. Westward bound will be in order for any system in the gulf and Caribbean right now. Things are getting dry in these parts, slowly but surely, and some have been dry previous to. We need some rain.
