2012 Hawaii hailstorm
On the morning of March 9, 2012, a particularly devastating and long-lived hailstorm hit the Hawaiian islands of Oahu and Lanai. The hailstorm was produced by a supercell thunderstorm. This event produced the largest hailstone ever recorded in Hawaii since records began in 1950. The hailstone was measured at long, tall, and wide. National Weather Service meteorologist Tom Birchard stated that the event was "unprecedented."
In addition to the spectacular early-morning lightning storms and flooding from the 4 feet of rainfall received, a tornadic waterspout formed off the coast of Oahu during the morning of March 9, 2012. Non-supercullar waterspouts are not uncommon, this mesocyclone-induced waterspout tracked inland for 1.5 miles, becoming an EF0 tornado that caused minor damage to the Enchanted Lakes subdivision of Kailua at 7:10 am Hawaiian-Aleutian Time.
