atlantic Tropical Storm Lorenzo

[Somerset Squall]

It looks like the Atlantic has briefly awoken from it's slumber. But don't get too excited, because it looks like we may be in for a weak tropical storm at best with this system. 13L is located in the open waters of the central Atlantic, well east of Bermuda. Convection blossomed over the LLCC this afternoon, but already westerly shear is partially exposing the LLCC to the west of the convection. 13L could become a tropical storm over the next day or so whilst waters remain warm enough, but shear will cap any significant intensification. After a couple days, shear will rise further and waters cool along the east-northeast track, which will put an abrupt end to 13L's brief life.I still can't believe there have only been two hurricanes in the Atlantic, and they were only cat 1's!

Despite the shear, 13L has become Tropical Storm Lorenzo, with winds of 35kts. The LLCC remains on the western edge of the convection due to moderate shear. This shear will prevent significant intensification, but NHC do forecast a peak of 45kts. In 36hrs time, shear is set to rise significantly, and Lorenzo will also be heading into colder waters. These two factors will swiftly bring about weakening.

I think Lorenzo is going to be quite short lived: 

 

Tropical Storm LORENZO: Probability of tropical storm winds to 69 hours lead

Lorenzo has strengthened to 45kts. Earlier, a central dense overcast (CDO) feature formed. Since then, shear has increased, displacing this CDO slightly east of the centre of circulation. Lorenzo has probably peaked as shear looks set to rise further tomorrow.

Lorenzo already looks set to be weaken?
