Lorenzo dissipates over the open Atlantic

Lorenzo is no more. The remnants are moving toward the northeast near 18 mph over the open Atlantic.

Visible satellite imagery shows that Lorenzo no longer has a well-defined circulation and has dissipated. This marks the final advisory on 12th named storm of the season.

No additional development is forecast through the next seven days.

Beyond the next seven days, we'll be focused on the Caribbean Sea.

In late October and November, most development takes place in the Caribbean Sea. That's because wind shear weakens in this basin while it increases over the Atlantic.

Furthermore, sea surface temperatures in the Caribbean remain quite warm through November, making it a hotspot for potential development.

The season seems really calm. Is it close to "average?"

For the Gulf and Caribbean, the season has been exceptionally inactive. For these two basins in particular, this is the least active season since 1991. But, with development in the Atlantic, and many "fish storms," the season is on par for average to this point.

The hurricane season officially ends on November 30.
