Mars Rock Formation Poses Mystery-2

Chantal's satellite presentation has deteriorated markedly this morning and is barely classifiable by the Dvorak Technique. Forecasted strong westerly shear and interactions with land over the next couple of days should cause further weakening of the storm as it transitions back into a tropical wave. Tropical Storm Warnings remain in effect for the entire coast of the Dominican Republic, the entire coast of Haiti, Turks and Caicos and the southeastern Bahamas. This image was taken by GOES West at 1200Z on July 10, 2013.
