Heavy rain bands associated with Lowell will begin to impact the state late Sunday and a Flood Watch has been issued for the entire state. The heaviest rainfall is expected to be on Kauai and southeast slopes of the Big Island.

WTPA42 PHFO.
WIND: Hurricane conditions are expected on the Big Island of Hawaii by early Saturday, with tropical storm conditions possible in Maui County by late Saturday. Wind speeds atop and on the windward
sides of slopes 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 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 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.
