Hurricane Lane - 180824 Friday 2am

Hurricane Lane is a slow moving storm tracking north at 5 mph. Its center is south of Maui. It is expected to turn west sometime today or tomorrow. How far north it moves before making the turn will determine how severely the main Hawaiian Islands are impacted. Tropical storm force winds are not expected to affect Oahu till early this evening. Expect loss of electric power. Heavy rain and flash flooding will happen. If you are in a flood zone know that it is called a flash flood because flooding will happen in a flash. GET OUT OF FLOOD ZONES before the storm hits.

KEY MESSAGES:
 
1. It is vital that you do not focus on the exact forecast track or
intensity of Lane, and remain prepared for adjustments to the
forecast. Although the official forecast does not explicitly
indicate Lane's center making landfall over any of the islands, this
remains a very real possibility. Even if the center of Lane remains
offshore, severe impacts could still be realized as they extend well
away from the center.
 
2. Lane will pass dangerously close to the main Hawaiian Islands as
a hurricane on Friday, and is expected to bring damaging winds.
Terrain effects can cause strong localized acceleration of the wind
through gaps and where winds blow downslope. These acceleration
areas will shift with time as Lane passes near or over the islands.
Winds will also be stronger at the upper floors of high rise
buildings.
 
3. The slow movement of Lane also greatly increases the threat for
prolonged heavy rainfall and extreme rainfall totals. This is
expected to lead to major, life-threatening flash flooding and
landslides over all Hawaiian Islands.
 
4. Large and damaging surf can be expected along exposed
shorelines, especially along south and west facing coasts, with
localized storm surge exacerbating the impacts of a prolonged period
of damaging surf. This could lead to severe beach erosion.
