VILLAHERMOSA – Hurricane watches were in effect yesterday for a stretch of Gulf Coast in southern Texas and northern Mexico as Tropical Storm Alex gained strength and appeared on track to become a Category 3 hurricane before it makes landfall later this week.

The storm is expected to become a hurricane today, and could build winds as high as 120 mph by tomorrow.Tropical storm-force winds extended up to 70 miles from the storm’ s centre yesterday, and Alex was moving slowly to the northwest.
