As Erin grows in size, rough ocean conditions will affect a large portion of the western Atlantic. Forecast products may currently underestimate the likelihood of strong winds beyond 36 hours, as Erin’s wind field is larger than the typical storm used to generate those estimates.

A Gulf disturbance has a low chance of becoming a tropical storm, but it could bring rain, high surf and deadly rip currents to the Texas coast.

A tropical disturbance along the Gulf could develop into a depression before moving into South Texas and northeastern Mexico Friday evening. Any development into a depression would likely be "short-lived," the National Weather Service said.
