HAZARDS AFFECTING LAND
----------------------
Key messages for Nolo can be found in the Tropical Cyclone
Discussion under AWIPS header HFOTCDCP2 and WMO header WTPA42 PHFO.
 
WIND: Tropical storm conditions are expected to begin by late
Friday in the warning area, with hurricane conditions possible by
early Saturday.
 
Tropical storm conditions are possible in the tropical storm watch
area beginning on Saturday.
 
RAINFALL: For the Big Island, Nolo will produce rainfall totals of
15 to 30 inches with maximum amounts of 35 inches.  This rainfall
could produce catastrophic life-threatening flooding and mudslides,
especially in areas of steep terrain.
 
For Maui, rainfall totals of 5 to 10 inches with maximum amounts of
20 inches are expected. Life-threatening flooding and mudslides are
possible, especially in areas of high terrain.
 
Across the remainder of the Hawaiian Islands, rainfall totals of 1
to 3 inches with maximum amounts of 6 inches are expected with
isolated flooding possible.
 
For a complete depiction of forecast rainfall associated with Nolo,
please see the National Weather Service Storm Total Rainfall Graphic
available at hurricanes.gov/graphics_cp2.shtml?rainqpf
 
STORM SURGE: The combination of a dangerous storm surge and the tide
will cause normally dry areas near the coast to be flooded by rising
waters moving inland from the shoreline. The water could reach the
following heights above ground somewhere in the indicated areas if
the peak surge occurs at the time of high tide...
 
Hawaii County...1 to 3 ft
 
The deepest water will occur along the immediate coast near and to
the right of the landfall location, where the surge will be
accompanied by large and dangerous waves. Surge-related flooding
depends on the relative timing of the surge and the tidal cycle,
and can vary greatly over short distances. For information
specific to your area, please see products issued by your local
National Weather Service forecast office.
 
For a complete depiction of areas at risk of storm surge
inundation, please see the National Weather Service Peak
Storm Surge Graphic, available at
hurricanes.gov/graphics_cp2.shtml?peakSurge.
 
SURF: Swells generated by Nolo are expected to reach exposed east
and south-facing shores of the Big Island by Friday, spreading
westward and building through the weekend. These swells are likely
to cause life-threatening surf and rip current conditions. Please
consult products from your local weather office.
