1) “Hurricane Katrina: Race Against Time” conclusion, 8 and 9 p.m., National Geographic, rerunning at 11 and midnight. Sunday’s hours (rerunning from 5-8 p.m. today) showed the storm crush New Orleans and others. In the aftermath (shown here), we see rescue efforts continue. In the final hour, some people rebuild the city; others find new lives elsewhere.
2) “Lego Masters” finale, 8 p.m., Fox. An impressive season peaked last week, with Lego creations that sent ping-pong balls on wild rides. Now three duos remain — brothers, siblings and school colleagues (a coach and a band director). It’s Will Arnett’s last episode as host. Kelly Osbourne follows with four junior episodes; then Nick Cannon takes over next year.
3) “Survival Mode,” 10 p.m., NBC. Here’s another disaster, this one more man-made. In 2017, a new rail route opened, aimed at saving 10 minutes in the Seattle/Portland route. The inaugural train derailed, killing three and injuring 57, plus eight more in nearby cars. Three soldiers from those cars rushed to help passengers escape the wreckage.
4) “Match Game,” 10 p.m., ABC. This is a quick rerun of Wednesday’s opener, hosted by Martin Short. The panel includes Selena Gomez, his “Only Murder in the Building” colleague, and Cara Delevingne, who played her friend in the show’s second season.
5) ALSO: On “FBI’ (9 p.m., CBS), a CEO has been killed inside a high-security penthouse. For lighter fare, try movies on BBC America (the “Crocodile Dundee” films at 6:30 and 8:30) or Freeform (“Coco” at 6:30, “Encanto” at 8:30).
