WATCHING THE TROPICS

Models suggest Tropical Depression Two will remain a tropical storm, but weak steering currents make its path uncertain.

The Cone of Uncertainty released by the National Hurricane Center predicts the possible location of the center of a tropical system. Towards the end of the week, when the system moves towards Texas, the central location could lie anywhere between Dallas and Corpus Christi. As a result, impacts will depend on whether the system moves over water or over land. Gulf Coast residents should monitor the latest updates.
