Coast Guard proposes permanent safety zone rule for severe weather in Mobile Bay area

The Coast Guard is proposing a new regulation that would establish a permanent framework for closing navigable waters in the Sector Mobile Captain of the Port zone during hurricanes, tropical storms, and other severe weather events. Currently, these closures often happen on an ad-hoc basis as storms approach. This rule aims to standardize how and when those areas are restricted.

Why it matters: This action shifts weather-related waterway closures in the region from reactive measures to a pre-established legal framework. For commercial shippers and recreational boaters, this means clearer expectations about when waters will be closed and what preparation steps are required. It reduces ambiguity during high-stress storm events, though it does not change the Coast Guard’s existing power to close waterways for safety.

Who it affects

• Vessel owners and operators transiting or working in the Mobile COTP zone
