The latest forecast track brings the center of Hone near the South Point of the Big Island from Saturday night into Sunday morning as a strong tropical storm. Hone will then strengthen to a Hurricane late Sunday as it passes south of Oahu and Molokai. 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 over island mountains, through passes, and downslope from higher terrain. This includes areas like the Humuula Saddle, the Waimea Saddle, leeward Kohala, and South Point. Persistent rainbands within the deep tropical moisture 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, Puna, and Kau Districts appear to have the highest risk for flash flooding. A few heavy showers and thunderstorms may persist over leeward and upslope portions of the Big Island into Monday. Swells associated with Hone are expected to bring high surf and strong rip currents to east and southeast facing shores of the Big Island, from late Saturday through Sunday. Listen for later High Surf Advisories or Warnings that may be needed for further information. POTENTIAL IMPACTS ----------------- * WIND: Prepare for dangerous wind having possible significant impacts across portions of the Big Island. Potential impacts in this area include: - Some damage to roofing and siding materials, along with damage to porches, awnings, carports, and sheds. A few buildings experiencing window, door, and garage door failures. Mobile homes damaged, especially if unanchored. Unsecured lightweight objects become dangerous projectiles. - Several large trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Several fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. A few bridges, causeways, and access routes impassable. - Scattered power and communications outages, but more prevalent in areas with above ground lines. * SURGE: Little to no storm surge flooding: - The storm surge threat has remained nearly steady from the previous assessment. - PLAN: There is little to no threat of storm surge flooding. Rough surf, coastal erosion, and life-threatening rip currents are possible. - PREPARE: Little to no preparations for storm surge flooding are needed. - ACT: Follow the instructions of local officials. Monitor forecasts. * 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. 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 AM HST, or sooner if conditions warrant. $$ $$
