This product covers the Hawaiian islands *FLOOD RISK REMAINS THOUGH TROPICAL STORM WARNINGS DISCONTINUED AS LALA MOVES AWAY FROM THE STATE OF HAWAII** NEW INFORMATION --------------- * CHANGES TO WATCHES AND WARNINGS: - All watches and warnings have been canceled * CURRENT WATCHES AND WARNINGS: - None * STORM INFORMATION: - About 190 miles west-southwest of Lihue or about 260 miles west of Honolulu - 20.7N 162.0W - Storm Intensity 60 mph - Movement West or 270 degrees at 13 mph SITUATION OVERVIEW ------------------ Tropical storm Lala is moving away from the state, and while winds have lowered to allow the discontinuation of all tropical storm warnings, the threat of flooding will persist over much of the Hawaiian Islands tonight. Moisture trailing Lala to the east has been producing isolated areas of flooding this afternoon on Maui, Oahu, and Kauai, with many windward areas receiving 2 to 4 inches of rainfall. Additional rain of generally 1 to 3 inches is expected, which can quickly result in flash flooding on saturated ground. Rough east swell generated by Lala will maintain elevated this evening and will decline late tonight and Monday. POTENTIAL IMPACTS ----------------- * WIND: Little to no wind impacts are anticipated at this time across the Hawaiian islands. * SURGE: Little to no surge impacts are anticipated at this time across the Hawaiian islands. * FLOODING RAIN: Additional impacts from flooding rain are still a concern from Maui to Kauai. Remain well guarded against dangerous flood waters having further impacts of significant potential. * TORNADOES: Little to no tornado impacts are anticipated at this time across the Hawaiian islands. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * OTHER PREPAREDNESS INFORMATION: Do not go sightseeing within impacted communities. Sightseers interfere with the emergency work of first responders. When clearing out fallen trees, be careful with chainsaws and axes. Always wear protective gear and keep others at a safe distance. Leaning trees and those which have fallen on roofs or power lines can be especially dangerous. If you are not in good health or unsure about what you are doing, have someone with tree cutting experience do the job. Never cut trees without a partner. If using a generator, avoid carbon monoxide poisoning by following instructions provided by the manufacturer. Operate your generator in a well-ventilated space outside of your living area and away from open doors and windows. Problems with sewer backups can further contaminate standing flood waters. Keep children away from flood waters. Also, listen for boil water alerts as tap water may have become non-potable. Be alert for potential flooding from rising rivers and streams which may have yet to crest. Remain informed of the latest river forecasts and heed any flood watches and warnings. * ADDITIONAL SOURCES OF INFORMATION: - For information on appropriate preparations see ready.gov - For information on creating an emergency plan see getagameplan.org - For additional disaster preparedness information see redcross.org NEXT UPDATE ----------- As it pertains to this event...this will be the last local statement issued by the National Weather Service in Honolulu HI regarding the effects of tropical cyclone hazards upon the area.
