**ALL TROPICAL WATCHES AND WARNINGS HAVE BEEN CANCELLED**
NEW INFORMATION ---------------
* CHANGES TO WATCHES AND WARNINGS: - All watches and warnings have been canceled
* CURRENT WATCHES AND WARNINGS: - None
* STORM INFORMATION: - About 330 miles south-southeast of Honolulu - 16.7N 156.5W - Storm Intensity 90 mph - Movement West or 265 degrees at 8 mph
SITUATION OVERVIEW ------------------
Hurricane Nolo is moving west and will pick up speed as it strengthens into a major hurricane later tonight or early Sunday. Nolo is forecast to turn toward the northwest Monday and Tuesday. While the center of Nolo will stay well south and west of the state, strong gusty winds will still occur due to the tight pressure gradient between Nolo and high pressure to the north. On Big Island and in Maui County, a combination of High Wind Warnings for upper terrain and notoriously windy areas and Wind Advisories for remaining lower elevations will replace Tropical Storm Watches and Warnings. A Wind Advisory is also remains in effect for Oahu and Kauai.
Bands of moderate to heavy showers and thunderstorms may bring an additional 1 to 2 inches, isolated 4 inches, of rainfall to windward and southeast regions of Big Island. Periods of moderate to locally heavy rain may spread into Maui, introducing an additional 1 to 2 inches of rain. Localized heavy rain could produce significant flooding and mudslides, especially in areas of steep terrain or in areas that have already experienced flooding during previous storms. Terrain-enhanced rainfall from Nolo's outer rain bands may also reach the islands of Oahu and Kauai.
Swell generated by Nolo will bring dangerously large, rough surf and severe rip currents, especially for the east and south-facing shores of Big Island. A High Surf Warning is in effect for the south-facing shores of Big Island. A High Surf Advisory remains in effect for the east-facing shores of Big Island as well as the east-facing shores of Maui, Molokai, Oahu and Kauai.
POTENTIAL IMPACTS -----------------
* WIND: Little to no additional wind impacts expected. - Community officials are now assessing the extent of actual wind impacts accordingly. - Emergency response teams are attending to casualty situations as needed. - Emergency work crews are restoring essential community infrastructure as necessary. - If you have an emergency dial 9 1 1.
* FLOODING RAIN: Additional impacts from locally hazardous flooding are still a concern on Big Island. There is a Flood Watch in effect through tonight for Big Island.
* TORNADOES: Little to no impacts are anticipated at this time across the Hawaiian islands.
* SURGE: Little to no impacts are anticipated at this time across the Hawaiian islands.
PRECAUTIONARY/PREPAREDNESS ACTIONS ----------------------------------
* EVACUATIONS: Follow the advice of local officials
* OTHER PREPAREDNESS INFORMATION: Remain safely sheltered until conditions improve. When going outside be sure to stay away from downed power lines, hazardous debris and flooded areas.
If your home or shelter was damaged, be alert to the smell of gas leaks and be cautious around electrical wiring, broken glass, jagged metal and wood, and protruding nails and screws.
Check to see if everyone in your group is OK. Administer first aid to those who are injured. If possible, call 9 1 1 for any serious injuries. Remember, it may be difficult for emergency responders to arrive quickly.
Check in with your emergency points of contact. Let them know your location and status. Keep conversations short and to the point. Do not tie up communications systems.
Check on your neighbors. If necessary, help them connect with their points of contact.
Do not attempt to return to evacuated areas until local authorities have inspected roads and bridges and have given the all clear. Hazards like downed power lines and trees, washed out roads, continued flooding in low lying areas and non-functioning traffic lights make travel difficult.
Allow extra time for emergency vehicles to reach you as they navigate road hazards.
Do not attempt to return to evacuated areas until local authorities give the all clear. Allow time for officials to inspect bridges and overpasses and to mark washed-out roads.
When entering areas that have been heavily damaged, bring along a GPS-enabled device to help with street navigation. Do not drive on roads that have been marked closed.
Do not go sightseeing within impacted communities. Sightseers interfere with the emergency work of first responders.
When inspecting damage, use flashlights rather than candles or flamed lanterns. Be aware of sparks that can ignite natural gas or other leaking flammables.
Do not go up on your roof until the weather conditions are safe. Ladders can be slippery in the rain and unexpected wind gusts can blow you off the roof.
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 any lingering wind gusts which could take down weakened trees and/or power lines, collapse damaged structures, or cause flying debris.
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.
Be alert for flooded roads which could be compromised or littered with debris. Avoid travel until water levels subside and roads have been cleared. Do not drive through places where flood waters cover the road. Turn around, don't drown!
Have multiple ways to receive Tornado Warnings if issued. Consider nearby shelter options as you move about. Be ready to shelter quickly.
