A powerful kona storm will begin impacting the western end of the state today, then spread across the remainder of the smaller islands by midweek and the Big Island towards the end of the week. While flash flooding remains a major concern (see the Flood Watch for additional details), confidence is increasing that strong to severe thunderstorms may develop Wednesday into the weekend. Damaging winds will likely be the primary hazard with these storms, though large hail cannot be ruled out. In addition to the heavy rainfall and severe thunderstorm threat, strong and potentially damaging kona winds are possible late in the week and into the weekend.
