Storm impacts

Your HNN First Alert Weather Team has declared Friday night, Saturday, and Sunday as First Alert Weather Days.

Wind

Hurricane conditions are expected on the Big Island of Hawaii on Saturday, with tropical storm conditions expected in Maui County Saturday night. Tropical storm conditions are possible in Oahu and Kauai Counties by Sunday morning. Wind speeds atop mountains and on the windward and leeward slopes are often up to 30 percent stronger than the near-surface winds indicated in this advisory, and in some elevated locations could be even greater.

Rain

Tropical Storm Lala is expected to produce rainfall totals of 8 to 12 inches across Maui and the Big Island, with maximum totals of 25 inches possible across the Big Island. Rainfall totals of 4 to 6 inches with maximum amounts of 8 inches are expected across the remainder of the island chain. This rainfall may producelife-threatening flooding and mudslides, especially in areas of steep terrain.

Storm surge

The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide.

The deepest water will occur along the immediate coast, where the surge will be accompanied by large and dangerous waves. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

Surf

Swells generated by Lala are expected to reach the east-facing shores of the state today, spreading westward and building through the weekend. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
