* LOCATIONS AFFECTED - Pukoo - Halawa Valley - Kalaupapa

* WIND - LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind - Peak Wind Forecast: 30-40 mph with gusts to 55 mph - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for wind 74 to 110 mph - PLAN: Plan for life-threatening wind of equivalent CAT 1 or 2 hurricane force due to possible forecast changes in track, size, or intensity. - PREPARE: Efforts to protect life and property should now be rigorously underway. Prepare for considerable wind damage. - ACT: Act now to complete preparations before the wind becomes hazardous. - POTENTIAL IMPACTS: Extensive - Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. - Many large trees snapped or uprooted along with fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. - Large areas with power and communications outages.

* STORM SURGE - No storm surge inundation forecast - POTENTIAL THREAT TO LIFE AND PROPERTY: Little to no storm surge flooding - 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. - POTENTIAL IMPACTS: Little to None - Little to no potential impacts from storm surge flooding.

* FLOODING RAIN - LATEST LOCAL FORECAST: Flash Flood Watch is in effect - Peak Rainfall Amounts: Additional 6-10 inches, with locally higher amounts - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for extreme flooding rain - PLAN: Emergency plans should include the potential for extreme flooding from heavy rain. Evacuations and rescues are likely. - PREPARE: Urgently consider protective actions from extreme and widespread rainfall flooding. - ACT: Heed any flood watches and warnings. Failure to take action will likely result in serious injury or loss of life. - POTENTIAL IMPACTS: Devastating to Catastrophic - Extreme rainfall flooding may prompt numerous evacuations and rescues. - Rivers and tributaries may overwhelmingly overflow their banks in many places with deep moving water. Small streams, creeks, canals, arroyos, and ditches may become raging rivers. In mountain areas, deadly runoff may rage down valleys while increasing susceptibility to rockslides and mudslides. Flood control systems and barriers may become stressed. - Flood waters can enter numerous structures within multiple communities, some structures becoming uninhabitable or washed away. Numerous places where flood waters may cover escape routes. Streets and parking lots become rivers of raging water with underpasses submerged. Driving conditions become very dangerous. Numerous road and bridge closures with some weakened or washed out.

* TORNADO - LATEST LOCAL FORECAST: - Situation is somewhat favorable for tornadoes - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for a few tornadoes - PLAN: Emergency plans should include the potential for a few tornadoes. - PREPARE: If your shelter is particularly vulnerable to tornadoes, prepare to relocate to safe shelter before hazardous weather arrives. - ACT: If a tornado warning is issued, be ready to shelter quickly. - POTENTIAL IMPACTS: Limited - The occurrence of isolated tornadoes can hinder the execution of emergency plans during tropical events. - A few places may experience tornado damage, along with power and communications disruptions. - Locations could realize roofs peeled off buildings, chimneys toppled, mobile homes pushed off foundations or overturned, large tree tops and branches snapped off, shallow-rooted trees knocked over, moving vehicles blown off roads, and small boats pulled from moorings.

* WIND - LATEST LOCAL FORECAST: Below tropical storm force wind - Peak Wind Forecast: 25-35 mph with gusts to 50 mph - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for wind 74 to 110 mph - PLAN: Plan for life-threatening wind of equivalent CAT 1 or 2 hurricane force due to possible forecast changes in track, size, or intensity. - PREPARE: Efforts to protect life and property should now be rigorously underway. Prepare for considerable wind damage. - ACT: Act now to complete preparations before the wind becomes hazardous. - POTENTIAL IMPACTS: Extensive - Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks. - Many large trees snapped or uprooted along with fences and roadway signs blown over. - Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges, causeways, and access routes impassable. - Large areas with power and communications outages.
