Two tropical waves to monitor in the Atlantic

We now have two areas to keep tabs on in the deep tropics. Both systems are far from land and really don’t have much of a future ahead of them due to limiting factors in the atmosphere.

The first, invest area 96L, is the eastern most tropical wave with a weak surface low associated with it. Overall, the system has become better organized since yesterday. The development of new convection or thunderstorm activity seems to be persisting though it is not very strong due to weak instability and overall upward motion in the region. This will likely keep 96L from strengthening too much in the coming days as it moves steadily westward over the open Atlantic.

Next we have area 97L which is moving a lot faster towards the west due to strong high pressure to its north. Convection is limited right now and the quick pace of movement will likely help to hinder additional development as the wave of low pressure continues westward.

It does appear that portions of the Leeward Islands will experience a period of squally weather as the tropical wave passes through this weekend. Interests in the region, especially boaters out in the open water, need to be aware of this system.

The fast movement of 97L means that what ever energy survives the coming days could end up in the western Caribbean early next week and while computer models are not indicating development there, we’ll have to watch to be sure. I still think it is just a little early to expect prolific development out of these tropical waves just yet. Give it another couple of weeks and things will probably be different and this makes sense considering the normal uptick in activity as we head in to August.

Meanwhile, the eastern Pacific refuses to shut down completely. We now have invest area 91E which is well on its way to developing well off the coast of Mexico. Fortunately, the steering pattern remains locked in for now and what ever manages to get going will move farther out in to the Pacific and not be an issue for Mexico.

I will have more here over the weekend.
