The lumber-carrying cargo ship broke in two, the bow section sinking and the stern section remaining afloat to be salvaged later. Following the attack, the crew sailed towards the Norwegian coast in two lifeboats. Shortly after the incident, the lifeboats were spotted by a seaplane of the Royal Norwegian Navy Air Service. "Storm" was directed to the scene, and took the lifeboats under tow to Sund near Bergen. When the Germans invaded Norway on 9 April 1940, "Storm" was patrolling near Buarøy off Bergen under the command of Lieutenant Thorleif Pettersen. This made "Storm" the only Norwegian torpedo boat to be ready for action at the time of the German attack; all the 16 other torpedo boats were either in port, in transit or undergoing repairs. On 9 April 1940, "Storm" was guarding the approaches to Bergen, a restricted naval port, and was under orders to fire at any intruder. Reports of foreign warships moving against Norway had motivated the naval commander in Bergen, Rear-Admiral Carsten Tank-Nielsen to put his forces on a war footing. Lieutenant Pettersen had suggested to Admiral Tank-Nielsen placing his vessel at the outer line of the restricted area, with further forces closer to Bergen. Before reaching the area covered by "Storm", any intruders would have to pass a line of small patrol boats with the task of identifying incoming ships and reporting back to Tank-Nielsen. By 22:00 on 8 April, "Storm" was in position to defend the Bergen approaches. When the German task force detailed to capture Bergen arrived at the Lerøyosen approaches around 02:00, the advancing warships were illuminated by searchlights at the outlying Lerøy Fort. At 02:20 "Storm" fired her bow torpedo at the last of the intruding ships, most likely the E-boat support ship , at a range of . The torpedo fired by "Storm" missed and failed to detonate. Lieutenant Pettersen overestimated the speed of the incoming German ships, and the torpedo passed in front of the target. The torpedo was found by "Storm" later in the day and destroyed. The German task force pushed on towards Bergen, seizing the city after a battle with the coastal artillery batteries there. Following the attack, the German E-boats "S-21" and "S-24" attempted to intercept "Storm", but the Norwegian torpedo boat managed to evade them. In the opinion of Lieutenant Pettersen, expressed in a post-war report, the torpedo had hit its target, but failed to explode.
