Hurricane Hell: 30 Deadly Days (Channel 5, 10pm)

IN summer 2017, three monster hurricanes swept in from the Atlantic one after another, shattering storm records and killing hundreds of people. First, Harvey brought catastrophic rain and flooding to Houston, causing $125billion in damage. Less than two weeks later, Irma lashed the Caribbean with 180mph winds - and left the island of Barbuda uninhabitable. Hot on Irma's heels, Maria intensified from a Category 1 to a Category 5 hurricane in just 30 hours, then ravaged Puerto Rico and left millions of people without power. As the planet warms, are these superstorms the new normal? Experts investigate.

Faith Behind Bars (BBC1, Regions Vary)

IF most of what you know about prison chaplains comes from movies and novels, then you may think that their main role is to hear devastating confessions and then wrestle with their faith over whether they can reveal what they know. However, this insightful documentary finds that while the job may not be all that melodramatic, it does have some big challenges. With access to HMP Edinburgh, it follows the chaplains as they give spiritual guidance and religious support to offenders, including some who have been convicted of the most serious crimes. As well as offering a look at what the position entails, the film also raises bigger questions about whether anyone can be forgiven, regardless of what they've done.
