    Key messages for Lowell can be found in the Tropical Cyclone
    Discussion under AWIPS header HFOTCDCP4 and WMO header WTPA44
    PHFO.
     
    RAINFALL: Additional rainfall of 1 to 3 inches are expected across
    the Big Island and eastern Maui with isolated maximum amounts of 5
    inches possible across the Big Island. This may result in additional
    flooding of urban and low-lying portions of the Big Island.
    Additional rainfall of 2 inches or less is expected elsewhere across
    the island chain. The additional rainfall could still promote
    instances of new flooding or prolong any on-going flooding.

    HAZARDS AFFECTING LAND
    ----------------------
    Key messages for Lowell can be found in the Tropical Cyclone
    Discussion under AWIPS header HFOTCDCP4 and WMO header WTPA44
    PHFO.
     
    WIND: Hurricane conditions are occuring across portions of Kauai
    County. Wind speeds atop and on the windward and leeward sides of
    hills and mountains are often up to 30 percent stronger than the
    near-surface winds. Tropical storm conditions, especially in gusts,
    are occurring on Oahu.
     
    Hurricane conditions are ongoing in the Papahanaumokuakea
    Marine National Monument between Nihoa and French Frigate Shoals.
     
    RAINFALL: Hurricane Lowell is expected to produce additional 
    rainfall totals of 2 to 4 inches for Kauai, with maximum storm 
    totals of 24 inches possible. For the Big Island, an additional 3 to 
    6 inches of rain is expected with isolated storm totals of 8 inches 
    possible. For Oahu and Maui counties, an additional 1 to 3 inches of 
    rain is expected with isolated storm totals of 8 inches possible. 
    This rainfall may produce significant flash flooding and mudslides, 
    especially across Kauai county and portions of the Big Island.

    Hurricane Lowell, please see the National Weather Service Storm 
    Total Rainfall Graphic available at
    https://www.nhc.noaa.gov/graphics_cp4.shtml?rainqpf
     
    STORM SURGE:  Water levels may remain elevated along the coasts of 
    Niihau, Kauai, and Oahu due to large waves, and will begin to 
    subside after the next high tide cycle.
     
    SURF: Swells from Lowell will continue to generate life-threatening
    surf and rip current conditions during the next few days across many
    of the Hawaiian Islands. Please consult products from your local
    weather office.

    DISCUSSION AND OUTLOOK
    ----------------------
    At 200 AM HST (1200 UTC), the center of Hurricane Lowell was located 
    by an Air Force Reserve Hurricane Hunter aircraft near latitude 22.9 
    North, longitude 160.8 West. Lowell is moving toward the north near 
    18 mph (30 km/h).  This general motion is forecast through today, 
    taking the core of Lowell farther from Kauai County. Lowell is then 
    forecast to turn toward the northwest and west and slow down on 
    Wednesday and Thursday after passing the main Hawaiian Islands.
     
    Maximum sustained winds have decreased to near 105 mph (165 km/h) 
    with higher gusts.  Further weakening is expected during the next 
    few days.  
     
    Hurricane-force winds extend outward up to 70 miles (110 km) from
    the center and tropical-storm-force winds extend outward up to 195
    miles (315 km). Lihue Airport (PHLI) along the southeastern coast of
    Kauai recently reported sustained winds of 53 mph (85 km/h) with a
    gust to 75 mph (121 km/h). Daniel K Inouye International Airport
    (PHNL) in Honolulu recently reported a gust of 43 mph (69 km/h).
     
    The estimated minimum central pressure is 965 mb (28.50 inches) 
    based on Air Force Reserve Hurricane Hunter dropsonde data.

    of 4 to 8 inches for Kauai, with maximum storm totals of 24 inches
    possible. For the Big Island, an additional 3 to 8 inches of rain is
    expected with isolated storm totals of 12 inches possible. For Oahu
    and Maui County, an additional 2 to 5 inches of rain is expected
    with isolated storm totals of 10 inches possible. This rainfall may
    produce significant flash flooding and mudslides, especially across
    Kauai County and portions of the Big Island.

    STORM SURGE: The combination of storm surge and 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...
     
    Kauai County...2-4 ft, with the highest expected values along the
    south coast of Kauai and the island of Niihau
    Oahu...Up to 1 ft
     
    The deepest water will occur along the immediate coast near and to
    the right of the center, where the surge will be accompanied by
    large and destructive waves. Surge-related flooding depends on the
    relative timing of the surge and the tidal cycle, and can vary
    greatly over short distances.
     
    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_cp4.shtml?peakSurge.
     
    TORNADOES: Several tornadoes are possible near Kauai and Niihau
    through the overnight period. A few tornadoes are also possible
    across the remainder of the Hawaiian Islands.
     
    SURF: Swells from Lowell will continue to generate life-threatening
    surf and rip current conditions during the next few days across many
    of the Hawaiian Islands. Please consult products from your local
    weather office.

    DISCUSSION AND OUTLOOK
    ----------------------
    At 1100 PM HST (0900 UTC), the center of Hurricane Lowell was 
    located near latitude 21.9 North, longitude 160.8 West. Lowell is 
    moving toward the north-northeast near 18 mph (30 km/h). A motion 
    toward the north-northeast and north at a similar forward speed is 
    forecast through Tuesday. The core of Lowell is expected to pass 
    near or just west of Niihau overnight into early Tuesday. Then, 
    Lowell is forecast to turn toward the northwest and west and slow 
    down on Wednesday and Thursday after passing the Hawaiian Islands.
     
    Maximum sustained winds are near 110 mph (175 km/h) with higher
    gusts. Lowell will remain a powerful hurricane while passing near 
    the Hawaiian Islands overnight into early Tuesday, and then 
    weakening is expected over the next several days.
     
    Hurricane-force winds extend outward up to 70 miles (110 km) from
    the center and tropical-storm-force winds extend outward up to 195
    miles (315 km). Barking Sands (PHBK) on western Kauai recently
    reported sustained winds of 51 mph (82 km/h) with a gust to 84 mph
    (135 km/h). Lihue Airport (PHLI) along the southeastern coast of
    Kauai recently reported sustained winds of 53 mph (85 km/h) with a
    gust to 79 mph (127 km/h). Daniel K Inouye International Airport
    (PHNL) in Honolulu recently reported a gust of 45 mph (72 km/h).
     
    The estimated minimum central pressure based on aircraft data is 
    963 mb (28.44 inches).
