NASA scientist Tom Reynolds thought everything would be fine when he moved to Seattle to be with his fiancé, Navy Lieutenant Emma Peterson. But when his gearhead son Wyatt can't stop fighting with her green-minded daughter Chloe, they realize that this new family may not make it. And things aren't just stormy on the home front; when an unidentified object is shot down by the military and crashes into Puget Sound, it sets off a series of strange weather phenomena: earthquakes, tornados, lightning storms... and they're spreading. Now, this new family must find a way to work together to save the city, and each other, before it's too late.

Although it's mentioned by any character, a tornado is measured by its destructive force with the Fujita's Scale. It was named after Tetsuya Fujita, who in 1971 in collaboration with Allan Pearson created a scale to differentiate a twister according the wind speed:
F0: 60-117 km/h or 45-72 mph (light damage).
F1: 117-181 km/h or 73-112 mph (moderate damage).
F2: 181-250 km/h or 113-157 mph (significant damage).
F3: 250-320 km/h or 158-206 mph (severe damage).
F4: 320-420 km/h or 207-260 mph (devastating damage).
F5: 420-510 km/h or 261-308 mph (incredible damage).
F6: 510-610 km/h or 309-379 mph (altough initially Fujita scale have five marks, in 1999 a tornado located in Bridge CreekMoore, Oklahoma, devastated with a force more powerful never seen before. It was the only one F6 registered in history). See more
Tom discovers that breathing on the compound causes it to grow because of moisture in an exhalation. When Tom demonstrates to the others (who are all standing close and breathing) how the compound acts on water, he does so using an open container. The compound should have affected the atmosphere in the room. See more
