 High Surf Warning  Statement as of 3:48 PM HST on December 20, 2014


... High surf warning remains in effect from 4 am Sunday to 6 am
HST Tuesday...

A high surf warning remains in effect from 4 am Sunday to 6 am
HST Tuesday.

* Surf... along north and west facing shores of Niihau and Kauai
and north facing shores of Oahu... Molokai and Maui... building
to 25 to 30 feet Sunday night and Monday. Along west facing
shores of Oahu and Molokai... building to 15 to 20 feet Sunday
night and Monday.

* Timing... warning level surf is expected to rapidly build by
daybreak Sunday on Kauai... during Sunday morning on Oahu... and
by midday Sunday across Maui County.

* Impacts... high... expect ocean water occasionally sweeping
across portions of beaches... very strong breaking waves and
strong longshore and rip currents. Breaking waves may
occasionally impact harbors making navigating The Harbor
channel dangerous.

Precautionary/preparedness actions...

Large breaking surf... significant shorebreak... and dangerous
currents make entering the water very hazardous. Anyone entering
the water could face significant injury or death. Boaters should
be aware of an increased number of surfers and body boarders
utilizing The Harbor channel to access surfing areas.






 Record Report  Statement as of 4:33 PM HST on December 20, 2014

NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Honolulu HI 
400 PM HST Sat Dec 20 2014 


Synopsis... 
weakening southeasterly flow will allow for land and sea breezes to 
develop through Sunday. A cold front approaching from the northwest 
will bring an increase in showers as early as Sunday night to Kauai. 
There is the potential for heavy rain and a few thunderstorms across 
the state from Monday afternoon through Tuesday. Strong northerly 
winds will develop behind the front. 


&& 


Discussion... 
water vapor imagery shows an upper level high northeast of the 
state...with a ridge extending across the islands. A sharp trough is 
located far to the northwest...moving to the southeast at 30 miles per hour. At 
the surface...a ridge is located less than 200 miles north of 
Kauai...and the approaching cold front is about 600 miles northwest 
of Kauai. 00z radiosonde observations from Hilo and Lihue show stable inversions near 
6kft. Precipitable waters are 0.8-0.9 inches...which is drier than 
normal for this time of year. Early afternoon mimic total 
precipitable imagery shows values of 0.8-1.0 inches extending 
several hundred miles upstream to the east of the state...with tpw 
values of 1.5-1.7 inches pooling along the cold front to the 
northwest. 


With the surface ridge being suppressed southward by the approaching 
front...low-level winds have already turned southeasterly across the 
smaller islands and onshore sea breezes developed during the day. 
Cloud motions show easterly winds still affecting The Big Island. 
Winds are expected to weaken further as the western extent of the 
ridge erodes with the approach of the cold front. Surface pressures 
across the state are about a millibar lower than 24 hours ago. The 
locally driven sea breeze/land breeze pattern will continue through 
Sunday. The stable and dry airmass will keep rainfall generally 
light...but we will see an increase in clouds and showers across 
interior and west/northwest sections during the late 
morning/afternoon. 


The upper level trough northwest of the state will propel the cold 
front toward Kauai by Sunday night. Most of the upper level support 
with this first trough will pass to our north...and the front is 
expected to lose some of its push. However...another piece of energy 
will dig down the back side of the trough and amplify near the 
islands...reinvigorating the front and driving it farther southeast. 
Cold air associated with this digging trough will also destabilize 
the airmass over the islands. 500mb temperatures drop to -12c to 
-14c. Moisture will be somewhat limited...with cross sections across 
the islands showing dry air above 700mb. However...model forecast 
soundings show the subsidence inversion eroding...leading to 
unstable profiles and relatively saturated low-levels. Differences 
remain between the GFS and European model (ecmwf)...with the GFS being more 
consistent through the extended forecast. The 12z European model (ecmwf) cuts off 
much of the digging energy southwest of the state while the GFS 
keeps the trough more progressive. By middle week the European model (ecmwf) trends back 
toward the GFS solution with the placement of a cutoff low 
developing northeast of the state. Overall the pattern has 
stabilized enough that we can start to add a better delineation of 
higher probability of precipitation as the front/trough swing through the state. Kept the 
broad brush of slight chance thunderstorms for a roughly 24 hour 
period generally Monday night/Tuesday. 


Strong north to northeasterly winds are expected to develop behind 
the front early in the new work week. These winds will gradually 
relax through the week...but remain generally out of the 
north-northeast due to the presence of the low that is expected to 
be northeast of the state. By late in the week this low will weaken 
and allow high pressure to build northwest of the state...which will 
allow winds to veer to a more northeasterly direction. 


&& 


Aviation... 
weak southeast flow is expected across the whole of the state 
through tomorrow as the cold front to our distant northwest begins 
its approach. Weak sea breezes this afternoon will be replaced by 
weak land breezes overnight only to redevelop tomorrow afternoon. 
Cloud cover this afternoon is focused over island interiors but 
should become more diffuse after sunset. Next band of trade wind 
showers coming out of the southeast should reach The Big Island and 
Maui late this evening. The airmass surrounding the islands is 
relatively dry and the subsidence inversion relatively low. Any 
precipitation next 24 hours should be light. Isolated MVFR conds 
possible in windward side showers overnight otherwise VFR conds will 
prevail all areas. 


&& 


Marine... 
a long period northwest swell generated by a large and powerful low 
pressure system is expected to bring warning level surf to the 
islands on Sunday. A Jason altimeter pass from late this morning 
just northwest northwest of the core of the highest seas supports 
the current wavewatch iii forecast. Ww3 shows a swell of 12-13 feet 
reaching buoy 51101 after midnight tonight. This swell will build 
across the islands on Sunday...then linger into Monday before 
gradually diminishing. Have issued a high surf warning for north and 
west facing shores of the smaller islands. Given the later timing 
for The Big Island /swell arriving Sunday night/ have held off on 
including the west side. However...wavewatch guidance of 6 feet/17 
seconds off the Kona coast will also lead to warning level surf 
there as well. Given the large swell...we have also issued a Small 
Craft Advisory for most coastal waters due to hazardous seas. 


Lifeguard reports from The Big Island indicate high surf conditions 
along east facing shores. The Hilo buoy has been relatively steady 
reporting combined seas of 9-10 feet...and the majority of the 
energy is from about 110 degrees at 10 seconds. Wavewatch guidance 
at that data point indicates this swell will continue at similar 
levels into Sunday before gradually diminishing. A high surf 
advisory remains in effect for east facing shores through Sunday. 
Given the swell direction out of the east-southeast and lower buoy 
readings/surf observations across the remaining islands...have 
confined the advisory to The Big Island. 


&& 


Hfo watches/warnings/advisories... 
high surf warning from 4 am Sunday to 6 am HST Tuesday for north and 
west facing shores of Niihau Kauai Oahu and Molokai and for north 
facing shores of Maui. 


High surf advisory until 6 PM HST Sunday for east facing shores of 
The Big Island. 


Small Craft Advisory from 4 am Sunday to 6 am HST Tuesday for all 
Hawaiian waters except Maalaea Bay.
