“Italian hurricane” is lunch room slang for spaghetti with garlic sauce. “Spaghetti and garlic: One Italian hurricane” was printed in the Middletown (NY) Times Herald on January 27, 1936. “Italian hurricane—spaghetti with garlic sauce” was printed in the book Hash House Lingo (1941) by Jack Smiley.
Lunch room slang became rare after 1960, and the term is mostly of historical interest.
