Tropical Storm Ernesto will continue moving through the Caribbean the rest of the weekend, and will gradually develop into a category one hurricane. The forecast track will take it over the Yucatan Peninsula on Wednesday. Its path after that will likely stay south of the Texas/Mexico border, but will continued to be watched closely.
Tropical Depression # 6 developed into Tropical Storm Florence Saturday afternoon. It is located in the eastern Atlantic. Although it has strengthened a bit, it will encounter unfavorable conditions in the coming days, and will likely weaken to just an area of low pressure. What is left of Florence will track north of Puerto Rico & the Windward Islands. If it survives, the low will track away from the eastern United States.
The National Hurricane Center continues to monitor a disturbance near Florida and the Bahamas. As of now, it does not have a high probability of developing much more.
More on these tropical systems can be found in the CBS 6 Hurricane Tracker.
