Weather

Oct 20, 2014 3:45 AM HST

Synopsis
All tropical storm warnings for the aloha state and coastal waters have been discontinued. Showers and slight chances of thunderstorms continue through the morning hours as Ana slowly pulls away from the aloha state. A moderate easterly and southeasterly flow will begin establishing during the next couple of days. Then light to moderate trades should prevail for the second half of the week with showers favoring windward and mountain areas. The trades should be light enough at times to allow for afternoon sea breezes to develop and bring clouds and a few showers over leeward and interior areas.

Discussion
All tropical storm warnings for the aloha state have been discontinued. A flash flood watch remains in effect for Oahu and Kauai county until 6 pm HST this evening, and it will be adjusted as necessary.

Radar data still show a rather large field of moisture associated with departing Ana, keeping plenty of showers and slight chances of thunderstorms around Oahu and Kauai county through the morning hours. And although conditions are slowly improving, it is possible to experience localized heavy showers today, especially over Kauai and Niihau. The 06Z soundings show a drier airmass starting to filter into the area from the E with pwats on the Hilo sounding at 1.4 inches, while Lihue still has more than 2 inches. But despite this trend, lingering moisture from Ana will still be able to fuel clouds and showers especially over the W half of the aloha state through Tue.

For the first half of the week, Ana will continue to move W and NW away from the islands and allow for a generally e/se moderate flow to begin establishing across the area starting today. Models are now backing down from keeping a more S flow over the W edge of the island chain. Thus, the forecast wind field across the area will be mainly from the e/se. An increasingly stable airmass will gradually move into the area in the wake of Ana.

For the second half of the week, model solutions show winds relaxing a little and allowing for sea breezes to become more prominent each afternoon, with clouds and showers affecting leeward and interior areas of the smaller islands and the Kona side of the Big Island.

Aviation
Overall conditions continue to improve for the islands as Ana moves away. Tropical storm Ana at 1200Z was located at 20.6°N 162.6°W, 200 nm WSW of PHLI. Kauai, including PHLI, is likely to experience extended periods of lower cigs/vis with deep layered clouds at least through the morning period. Slight chance for thunderstorms also remains over Oahu and Kauai through the morning. Airmet sierra for mountain obscuration and airmet zulu for icing remain posted over Kauai. They have been cancelled for all other areas.

Vfr conditions will prevail for terminals Oahu through Big Island. Showers will mainly focus on windward and mauka area as moderate E winds return to the state. Possible periods of MVFR conditions can be expected. High clouds will linger over Maui county and Oahu through the morning. Airmet tango is posted for low level turb.

See tc sigmet quebec series for tropical storm Ana.

Marine
A small craft advisory /sca/ remains in effect through this morning due to elevated rough seas across the waters surrounding Kauai and over parts of the Oahu leeward waters due to tropical storm Ana swells. As Ana continues to move west away from the area, these tropical cyclone swells will slowly diminish. Otherwise, winds and seas are expected to remain below the SCA criteria over the coastal waters through Friday.

The swells produced by Ana will also maintain elevated surf along west and south facing shores of Kauai and Niihau this morning. An above average north northwest swell will also keep the surf elevated along north facing shores of the islands from Kauai and Niihau to the Big Island. As a result, a high surf advisory remains in effect for these shorelines through this morning. The north northwest swell will eventually shift to a more northerly direction, and gradually lower through Wednesday. A new small northwest swell is expected to arrive Thursday and continue through Friday.

Watches/Warnings/Advisories
Flash flood watch until 6 pm HST this evening for Niihau, Kauai, Oahu.

High surf advisory until noon HST today for Niihau, Kauai windward, Kauai leeward, Oahu south shore, Waianae coast, Oahu north shore, Oahu Koolau, Molokai, Maui windward west, windward Haleakala, Big Island north and east.

Small craft advisory until noon HST today for Kauai northwest waters, Kauai windward waters, Kauai leeward waters, Kauai channel, Oahu leeward waters.
Otherwise only small to moderate swells are expected to affect west and north facing shores. A larger northwest swell is then expected over the weekend.

BIG SURF PICTURE
10/14/14 Tuesday

Saturday update. Building surf from the SE Cat1 hurricane Ana. Hit the Big Is by Friday night and will bring huge stormy East and 5-8' (possibly higher' local scale) SE swell to Big Is with up to 35 and higher kt gusts but the exact speed, swell size and angle will be veering have to be refined.

NPAC
The Jet stream has a deep long looping trough from off the Kurils up near the Aleutians and a dip SE near the east Aleutians. There are plenty broad weak flows off to our NE to the west coast. The Jet straightens out and breaks up by Friday with a deep trough dip SE near the central Aleutians and esp by Saturday winds increase to 160kts carrying a large Low our way for a big NNW Sunday. All in all more energy is flowing up there 30,000 feet.
Recent- Currently: We’ve been on the decline since out fat 8-12’ NW came last Fri-Sunday. It was 3’ Tuesday with even some south winds and clouds to give some atmosphere.
Next: We get some sideband NNE swell Wednesday from a Low in the Gulf and it’s fetch to the west last weekend into Tuesday but most it’s energy is off to the east. Surf should reach 2-3’ Wednesday with just 9 seconds and only for Laniakea and Kammies etc.
Next: The above low strengthened Monday-Tuesday with a long fetch again near the east Aleutians sending most its swell to Cali. The 25-35kts still should produce some sideband swell with 9 seconds and surf hts reaching easy 4’ maybe 5’ Thursday for those isolated spots.
Next: A complex Low spins up near the dateline Sunday-Monday and tracks NE as it goes away Tuesday night. Not much fetch from this source but still, we could get some 2-3’ WNW mixing with the N above.
Next: Former Typhoon Vong Fong which started toward the PI last Tuesday the 7th moved slowly NW into Taiwan and terrorizing the region through the weekend. It ran right over Japan and became a gender bender (warm core low to cold core). It then got absorbed into the mid level Jet stream trough today and begins a track leading to large surf. Wed-Thursday the 45kt and 35’ seas track ESE from up near the Aleutians hitting the dateline Thursday and passes to our N as it broadens. The fetch got close to only 1200 mile away by the weekend. (less distance means less decay of ocean swell means bigger surf). Long period forerunners hit late Saturday 3’ 20 sec from the first phase of the storm. The swells will rise to near 10’ with shorter but still healthy 15 seconds Sunday noonish. This should equate to 8-12’ NW surf Sunday midday to evening with a slight drop to 6-10’ Monday as it veers NNW to N and fades.
Last: We go into some down time from NW sources until a Kamchatka Low quickly tracks E-ESE Sunday-Tuesday crossing the dateline Monday up near the central Aleutians. By Tuesday we’ve had enough fetch to lend short 11 second support to the dropping prior swell Wednesday afternoon to 4-6’ from the NNW.

SPAC:
The Jet down under is broken, weak and zonal most of the 7 days forecast; a sign of the times as we head into Austral summer. Things will be quieting down and only exceptions will change the outlook.
Recent-current: We’ve been at slightly above summer averages so at least that’s good news. We’ve seen some 14 second SSW surf reaching solid 3’ today fading some Wednesday. It came from a gale Low east of NZL a week ago. Note south swells often take longer to build and last longer due to distance traveled. Longer periods stretch out as they move faster than the swells ‘average’ periods. Thus long periods get here 1st but are inconsistent. By the same token on the back end of the event, the shorter 13 seconds will be smaller but more consistent in the later stages.
Next: A weak low spins off far off NZL last Friday-Sat.. We ‘might’ see some background 2’ South this weekend.
Last: Long shot of SSW popping the buoy with 16 seconds late Monday the 20th reaching 2.5’ 15 sec Wednesday 22nd and if lucky this would mean some 2-3’ SSW waves to ride for a couple days. Long range outlooks are blurry.
Windward side: tiny 2’ back ground Trade swell until Friday when TS Simon and higher trades lift the surf to 1-3’ all weekend. Minor variations all next week.
Tropics: See the above discussion for former Super Typhoon Vong Fong which brings some isolated 2’ West surf Wed-Friday. And helps bring some Big NNW surf this weekend as a transformed extra tropical Low.

FETCH: Often called the fetch length, is a term for the length of water or distance over which a given wind direction has blown. Fetch length along with the wind speed (or strength) determines the size of waves produced. The longer the fetch length and the faster the wind speed, the larger and stronger the wave will be and vice versa.
CAPTURED or FOLLOWING FETCH: Not only does the fetch length determine the power and energy of the wave. Additionally, if the winds/fetch are blowing in the same direction as during the wave's or storm's lifetime, the wave will in turn be even stronger. The fetch is related to the orbit of the wave and track of the storm.The longer the wind drags along the sea the more energy the wave will have. This can be seen not just in vertical height measurement but in wave period (the measurement of waves through time).
WAVES PERIOD:Time, in seconds, between the passage of consecutive wave crests past a fixed point. In general the longer the period the bigger the wave. Windswell or 'close interval' swells are under 10 seconds. Big 'ground swells' are 17-20+ seconds (note: a 20+ second swell needs storm force 50+kt winds blowing over a 1500 mile fetch to be fully developed' into 20-25' beasts; these 20 second waves can be felt 1000 feet down!). This is why they jack so much more, pulling large amounts of H2O off the outer reefs.
