Atlantic Basin Remains Quiet for Now

The Atlantic Basin Remains Quiet for Now

No organized tropical systems are found in the Atlantic Basin at this time, and none are expected to develop over the next couple of days.

The mid- and upper-level flow across the northern Gulf of Mexico on eastward into the central North Atlantic remains strong from the west and west-northwest.

This should remain in place through the rest of the week and into the weekend.

These strong winds aloft will create too much shear to support any development north of 25 north.

Farther south, we see a large band of clouds, showers and thunderstorms along and near 10 north across the southern part of the North Atlantic.

A monsoon trough extends from the African coast westward to near 20 west then the ITCZ extends farther west all the way to the northern coast of South America.

This area remains very disorganized.

Tropical Depression 12 from the Pacific Basin is tracking to the east across southeastern Mexico, near the Isthmus of Tehuantepec.

Current computer models are showing this weak feature drifting eastward and back over the warm waters of the western Caribbean on Sunday or Sunday night.

This is just one of several possibilities with respect to where the remnant depression will end up.

Other scenarios keep the system over land creating a prolonged heavy rain event for parts of Central America through at least early next week.

Another possibility is that the feature will drift to the south and over the east Pacific to reorganize.

Any development of this feature will be slow to occur.

We will keep an eye on this area in case it does end up moving into the western Caribbean.

If it does, there is some lower-level and upper-level support for development next week.
