Creation and development
In June 2011, the serial's producer Cameron Welsh revealed that Home and Away would air a special week of episodes featuring a storm. In July, Welsh told entertainment website Digital Spy that there were plans for the "biggest stunt/disaster storyline" that production team had ever undertaken. He said they were in the final stages of post-production meaning that it would come to air "very soon".
In August, Rhiannon Fish who plays April Scott told TV Week that the storyline would focus on a "deadly storm" that crosses the path of Summer Bay. Fish said that filming of the storyline was "full on" and wind and rain machines were installed on set to create the correct environment. Fish added that the cast felt like they were filming during an actual storm. Ada Nicodemou who plays Leah Patterson-Baker revealed that one character would die in the storm, but was not permitted to reveal their identity. She also said her character Leah would become trapped inside the Pier Diner and worried about the whereabouts of her son VJ Patterson. As she is pregnant, when she discovers bleeding she presumes that she has miscarried. Nicodemou said the ill turn is down to the stress of the storm. Welsh later revealed more details on the storyline and the effects it would have on the characters. The main storyline threads feature the characters of Harvey Ryan and Roo Stewart facing danger when their boat capsizes during "rough seas". Alf Stewart and Romeo Smith (Luke Mitchell) then go on the trail to save their lives. The serial's local school, Summer Bay High would become the "evacuation centre". Then a collapsed roof then traps the characters of Bianca Scott and Heath Braxton.
