Laura exits, two more tropical waves emerge

I have been saying things will calm down through the weekend in the tropics.

I apologize. Mother Nature has other plans.




From the NHC

I really thought we would get a few days of “rest” before the next few waves would cruise off the African coast and grab the NHC’s attention.

Turns out, the NHC is trying to get a head start on tracking the next two waves.

1. A westward-moving tropical wave located over the far eastern tropical Atlantic near the Cabo Verde Islands continues to produce disorganized shower activity. Although environmental conditions are not expected to be conducive for development during the next couple of days, they are forecast to gradually become more favorable over the weekend and into early next week when the wave moves into the central and then western tropical Atlantic.
* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…20 percent.

2. Shower and thunderstorm activity has increased today in association with a tropical wave over the central tropical Atlantic. Gradual development of this system is possible over the next several days as it moves westward at 15 to 20 mph.
* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…30 percent.

The good news is that development does not look imminent, but during the next three to eight days, things may be a little conducive for development in the tropics.

The two waves worth noting are highlighted in the blue circles. This is from model data showing what the tropics may look like in four days. At this point, there are still just two tropical waves, nothing to indicate organization or intensification. But it will need to be monitored.
