The latest forecast track brings the center of Hone south of, or possibly near, the Big Island Saturday night into Sunday morning. Winds associated with Hone will increase over the Big Island on Saturday and may become locally damaging by nightfall. Tropical storm conditions, with sustained winds over 39 mph, are possible Saturday night into Sunday. Winds will be the strongest where they blow downslope from higher terrain, over headlands, and through passes. This includes areas like the Humuula Saddle, the Waimea Saddle, leeward Kohala, and South Point. Persistent rainbands on the north side of Hone may bring excessive rainfall and flash flooding to portions of the Big Island starting Saturday afternoon and continuing through the remainder of the weekend. The Hamakua, Hilo, and Kau Districts appear to have the highest risk for flash flooding. A few lingering heavy thundershowers may persist over portions of the Big Island into Monday, especially over leeward and upslope areas. See the latest Flood Watch for more details. Swell associated with Hone are expected to bring high surf and strong rip currents to east and southeast facing shores of the Big Island, starting later Saturday and persisting through the remainder of the weekend. Listen for later High Surf Advisories or Warnings that may be needed for further information. Preparations for Tropical Storm Hone should be completed by midday Saturday. POTENTIAL IMPACTS ----------------- * WIND: Prepare for hazardous wind having possible limited impacts from Oahu to the Big Island. Potential impacts include: - Damage to porches, awnings, carports, sheds, and unanchored mobile homes. Unsecured lightweight objects blown about. - Many large tree limbs broken off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs blown over. - A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways. - Scattered power and communications outages. * FLOODING RAIN: Prepare for dangerous rainfall flooding having possible significant impacts across portions of the Big Island: - Moderate rainfall flooding may prompt several evacuations and rescues. - Rivers and tributaries may quickly become swollen with swifter currents and overspill their banks in a few places, especially in usually vulnerable spots. Small streams, creeks, canals, arroyos, and ditches overflow. - Flood waters can enter some structures or weaken foundations. Several places may experience expanded areas of rapid inundation at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water as storm drains and retention ponds overflow. Driving conditions become hazardous. Some road and bridge closures. Prepare for locally hazardous rainfall flooding having possible limited impacts across portions of Maui. * OTHER COASTAL HAZARDS: Swells associated with Hone are expected to bring high surf and strong rip currents to east and southeast facing shores of the Big Island, starting later Saturday and persisting through the remainder of the weekend. Listen for later High Surf Advisories or Warnings that may be needed for further information. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow all advice of local officials. * OTHER PREPAREDNESS INFORMATION: Now is the time to check your emergency plan and emergency supplies kit and take necessary actions to protect your family and secure your home or business. When making safety and preparedness decisions, do not focus on the exact forecast track since hazards such as flooding rain, damaging wind gusts, storm surge, and tornadoes extend well away from the center of the storm. If you live in a place particularly vulnerable to flooding, such as a low-lying or poor drainage area, plan to move to safe shelter on higher ground. When securing your property, outside preparations should be concluded as soon as possible before conditions deteriorate. The onset of strong gusty winds or flooding can cause certain preparedness activities to become unsafe. Monitor weather.gov, NOAA Weather Radio and local news outlets for official storm information. Listen for possible changes to the forecast. * 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 ----------- The next local statement will be issued by the National Weather Service in Honolulu HI around 6 PM HST, or sooner if conditions warrant. $$
