Hurricane Lane Special Discussion Number 42
NWS Central Pacific Hurricane Center Honolulu HI EP142018
200 PM HST Fri Aug 24 2018
This special advisory reduces the current intensity of Lane to 75
kt based on rapid weakening of the associated cloud and radar
patterns observed over the past few hours, and adjusts the intensity
and wind radii forecast to better agree with current trends. There
are no other changes at this time. This special advisory takes the
place of the 2 pm intermediate advisory.
KEY MESSAGES:
1. One should not interpret the forecast westward turn south of the
islands as a lower threat to the islands. If Lane retains central
core convection longer than anticipated, the westward turn would
happen later, which could bring hurricane conditions to Maui County
or Oahu. This solution is still plausible at this time. Regardless
of whether Lane makes landfall, severe impacts are still possible
and the effects can extend far to the north and east of the center
of Lane.
2. Lane will remain dangerously close to the central Hawaiian
Islands as a hurricane today into tonight bringing damaging winds
to some areas. 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 greatly increases the threat for
prolonged heavy rainfall. This is expected to lead to major flash
flooding and landslides in some areas.
4. High and potentially damaging surf can be expected along exposed
south facing shorelines today through Saturday, which could cause
severe beach erosion in some areas.
