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 occurring in portions of the 
warning area in areas of steep terrain. Hurricane conditions are 
possible by early Saturday.
 
Tropical storm conditions are possible in the tropical storm watch
area beginning on Saturday. Gusts to tropical storm force are 
occurring in Maui County in areas of steep terrain.
 
Regardless of the exact track of Nolo, strong and gusty winds are
possible for all of the Hawaiian Islands through the weekend.
 
RAINFALL: For the eastern and southern portions of the Big Island,
Nolo will produce rainfall totals of 8 to 12 inches with maximum
amounts of 16 inches. This rainfall could produce significant,
life-threatening flooding and mudslides, especially in areas of
steep terrain.
 
For the western portions of the Big Island, rainfall totals of 1 to
3 inches with maximum amounts of 6 inches are expected. For eastern
Maui, rainfall totals of 4 to 6 inches with maximum amounts of 8
inches are expected. Life-threatening flooding and mudslides are
possible, especially in areas of high terrain.
 
Across the remainder of the Hawaiian Islands, maximum rainfall
totals of 1 to 2 inches are expected.
 
For a complete depiction of forecast rainfall associated with
Hurricane 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 and 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 today, 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.
