Please see below from SEFL:

Regarding Southeastern Freight Lines operational status due to Hurricane Beryl, please see below for the latest update. Attached is a list of embargoed zip codes.

Our Houston market sustained the biggest impact and continues to experience significant flooding and power outages resulting in widespread road and customer closures.  As a result, we have embargoed all points for Houston, TX (HOU) and South Houston, TX (SHO) until further notice.

The driver mobile devices have been updated for the embargo and drivers should avoid picking up freight destined for an embargoed point

We will continue to monitor the recovery efforts and provide updates on our operational status.

Thanks for your understanding and support!
