Tropical Atlantic is becoming a tropical paradise

This large tropical disturbance is traveling in the general direction of the northeastern Caribbean islands.



9 a.m. Eastern time update: As it moves off to the west, roughly in the general direction of the northeastern Caribbean islands, there is a slight probability that a significant tropical disturbance on the opposite side of the Atlantic will emerge. Its chances of developing are poor since it is slamming into a sizable region of extremely dry air mixed with Saharan dust.

Cloud clusters may be seen over the ocean to the north and in advance of the disturbance in the satellite picture. Those resemble fair-weather clouds that we may encounter over land. Rain clouds frequently rise higher in the atmosphere because the environment is too dry to support them.


The most significant consequence of this disturbance may be to moisten a corridor in the atmosphere for systems coming behind it, even though there is a remote probability that it will find a moist enough pocket and temporarily grow into a tropical depression or tropical storm.

Of fact, at this time of year we anticipate a train of disturbances departing from Africa. The prevailing dry air appears to be the main barrier to development. As a result, when a major system enters the Atlantic, it has the potential to suck moist air from the south and leave an atmospheric track that is more favorable for the development of subsequent disturbances.

The system that appeared to be a tropical storm in the western Gulf of Mexico never arrived there. It appeared to have a good circulation in the middle of the atmosphere. However, the circulation never established at the surface, which is where it matters.

The system barely made a difference as it traveled inland. It will merge with a larger, more northern-style low-pressure system over Texas, which will provide copious amounts of rain. The rain, if it doesn’t arrive all at once, will be an excellent remedy for the terrible drought conditions that have plagued the state and its neighboring regions. However, there is a chance of some flooding during periods of heavy rain. Everyone in Texas and the threatened areas needs to keep up with current events.

We’ll be paying close attention to the Atlantic over the next weeks to see if hurricane season begins as predicted by the calendar. The tropical Atlantic’s moistening appears to be the solution.
