Winds Shifting, Weather Pattern Changing Soon
Alerts (as of 1:00 a.m.)
Special Weather Statement: Coastal flooding is anticipated over the next several days along all shores of the Hawaiian Islands due to record level spring (king) tides. Impacts include beach flooding, standing water on roadways and low-lying areas near the coast. A large summer south swell is also filling in Friday and will exacerbate the problem leading to additional beach run up, flooding and erosion.
Small Craft Advisory: ʻAlenuihāhā channel and southeast and leeward Big Island waters through 6 a.m. Thursday.

As a weak upper level disturbance passed over the state this weekend some of those showers could get heavy over leeward and interior areas.
