Hurricane Hone will continue to move westward on a high confidence track for the next several days. At 4 am HST this morning, Hurricane Hone reached its closest point of approach to the Big Island passing approximately 45 miles south-southwest of South Point, Hawaii. Hone will move west of the area over the next few days. Rainfall of 6 to 10 inches has already fallen across windward Big Island over the past 18 to 24 hours, and shower bands continue to move into the east and southeast slopes as Hone brushes past the Big Island. Bands of additional heavy showers will keep a moderate to high threat of flash flooding today over Hawaii County. The greatest potential for flooding will be across the eastern and southeastern windward slopes of the Big Island; including the Hamakua, Hilo, Puna, and Kau Districts. Additional rainfall estimates over these areas through Monday will range from 3 to 6 inches. See the latest Flood Watch for more details. Portions of the Big Island continue to observe sustained surface winds this morning around 30 to 40 mph and gusts over 50 mph, while a few sites in and around Kohala Ranch have gusted over 60 mph. Strong locally damaging winds will continue over the Big Island through the morning with sustained winds over 40 mph and gusts in excess of 60 mph, especially for areas downslope from higher terrain and through passes. This includes areas like the Humuula Saddle, the Waimea Saddle, leeward Kohala, and South Point. Wind speeds will then weaken over the island from the afternoon through the evening hours. Large and disorganized short period swell associated with Hurricane Hone will bring elevated surf to east and southeast facing shores today. A High Surf Advisory is in effect east facing shores of the Big Island. POTENTIAL IMPACTS ----------------- * FLOODING RAIN: Potential impacts from the flooding rain are now unfolding across the Big Island. Remain well guarded against life-threatening flood waters having possible extensive impacts, mainly over windward areas. If realized, these impacts include: - Major rainfall flooding may prompt many evacuations and rescues. - Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, arroyos, and ditches may become dangerous rivers. In mountain areas, destructive runoff may run quickly down valleys while increasing susceptibility to rockslides and mudslides. Flood control systems and barriers may become stressed. - Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out. * WIND: Potential impacts from the main wind event are now unfolding across the Big Island. Remain well sheltered from dangerous wind having possible significant impacts. If realized, these impacts 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. * OTHER COASTAL HAZARDS: Large and disorganized short period swell associated with Hurricane Hone will bring elevated surf to east and southeast facing shores today. A High Surf Advisory is in effect east facing shores of the Big Island. PRECAUTIONARY/PREPAREDNESS ACTIONS ---------------------------------- * EVACUATIONS: Follow the advice of local officials * OTHER PREPAREDNESS INFORMATION: Now is the time to stay inside. Listen for updates and be ready in case you lose electrical power. Keep a battery-powered radio, charged cell phone and flashlight handy. 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. * 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 12 PM HST, or sooner if conditions warrant. $$ $$
