The area of thunderstorms located over the northwestern Carribean Sea has become more organized overnight. This morning high-resolution satellite data confirmed a defined low had formed, thus meeting the criteria for a tropical cyclone. Advisories on Tropical Depression #16 were initiated by the National Hurricane Center at 10 AM CT. Like our blog discussion, last night stated future ‘Nate’ will continue to move north/northwestward over the next few days before entering the southern Gulf of Mexico this weekend. A high pressure in the western Atlantic will eventually pull the system north and northeast, but it must be stressed the timing and location of that turn remain uncertain. Regardless of the eventual track of ‘Nate’, conditions will favor intensification with a relatively high possibility of becoming a hurricane before landfall. Let me state now that the probability of direct impacts on Texas from ‘Nate’ is very low. Those from Lousiana east to the gulf-facing Florida need to closely watch for new forecasts. This system has the potential of being a quickly intensifying hurricane once it enters the Gulf of Mexico.
