Tropical Storm Ignacio Gets Stronger.

"Ignacio continues to gather strength in a favorable environment for intensification about half way between Los Cabos, Mexico and Hilo, Hawaii.

The airmass that the storm is moving through has relatively low wind shear, or the change in wind speed with height. When wind shear is too significant, it can effectively rip apart the structure of a tropical cyclone. With limited wind shear in the storm's path, Ignacio should continue to get better organized over the next few days as it eventually turns west-northwest."
