Overnight, lightning strikes were numerous to the north, east and south of the Island of Hawaii, but now, some of that thunderstorm activity has come ashore along Hawaii Island's southeast coast. From Cape Kumukahi to South Point, rainfall rates have been measured at 1 to 2 inches per hour. Stay alert and take precautions for possible cloud to ground lightning strikes, ponding on roadways, and bad visibility for drivers in the heavy showers.
