Update from the National Weather Service:
Tropical Storm Olivia has increased its forward movement towards the islands. Expect strong winds, heavy rainfall, and high surf to impact the islands over the next couple of days. Damaging tropical storm force winds are expected on Oahu tonight.
Showers will gradually increase this afternoon ahead of Olivia. The chance for flooding rainfall will increase rapidly tonight and remain a significant threat through Thursday night. Storm total rainfall amounts of 5 to 10 inches are expected, with isolated maximum amounts up to 15 inches. Much of this rainfall will be focused on windward areas of the islands, especially from Oahu through the Big Island.
However, flooding is still a significant threat for all areas. Swells and surf generated by Olivia will continue to slowly build this afternoon, and reach damaging levels on some east facing shores later today through Wednesday. Surf heights along east facing shores are expected to reach up to 20 feet across Maui County and the Big Island, and 10 to 15 feet on all other islands. This surf is expected to result in significant beach erosion and overwash onto vulnerable coastal roadways, particularly during high tides.
