On the forecast track, Lala is forecast to be near or just south of the Big Island on Saturday, and pass south of the remainder of the islands later in the weekend. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Steady strengthening is forecast, and Lala is expected to become a hurricane as it approaches the Big Island. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. The minimum central pressure based on data from an Air Force reconnaissance aircraft is 1000 mb (29.53 inches).

WIND: Hurricane conditions are possible in the Big Island of Hawaii by early Saturday. Wind speeds atop and on the windward sides of hills and mountains 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. RAINFALL: Tropical Storm Lala is expected to produce rainfall totals of 5 to 10 inches across Maui and the Big Island with maximum totals of 25 inches possible across the Big Island. Rainfall totals of 2 to 4 inches with maximum amounts of 8 inches across the remainder of the island chain. This rainfall may produce life-threatening flooding and mudslides, especially in areas of steep terrain. For a complete depiction of forecast rainfall associated with Lala, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_cp2.shtml?rainqpf 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... Hawaii...1 to 3 ft 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. For information specific to your area, please see products issued by your local National Weather Service forecast office. For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_cp2.shtml?peakSurge. SURF: Swells generated by Lala are expected to reach the east-facing shores of the state on Friday, 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.
