A freak hailstorm pelted Hawaii with golf-ball to baseball-sized chunks of hail today (March 9).
The hailstorm was "unprecedented for Hawaii," National Weather Service (NWS) Meteorologist Tom Birchardtold the Associated Press. Some of the hailstones in Honolulu were up to 3 inches (7.6 centimeters) in diameter, according to the NWS. On Twitter and Facebook, pictures of the jagged hailstones were posted throughout the day. A waterspout — like a tornado over the water — was also reported today.
"I have never seen severe storms over Hawaii," tweeted AccuWeather.com meteorologist Henry Marguisty. "Storms with large hail and heavy rains are more like storms in the South."
