Arthur's Pass Visitor Centre Moved
The Visitor Centre in Arthur's Pass Village has been temporarily moved into a new premises until further notice, due to building defects found in the old building. A temporary visitor facility has been set up 200 metres away in the main part of the Village near the Alpine Lodge & Motel (limited parking available). It is open 8.30am to 4.30pm daily. All information resources for the Park are available.

Thieves breaking into vehicles
Thieves have been breaking into cars and motor-homes at various car-parks and some camp-sites along SH.73 on a regular basis (day & night). They have been stealing passports, credit cards, money, electronic devices and recreation equipment. Take your absolute valuables with you on the walks, and don't leave other valuable items in plain sight in your vehicle. Report any suspicious activity to Police '111', and note down registration plates of vehicles!

Avalanche Risk (MSC)
Mountain Conditions
General Conditions (Updated 0734hrs Tuesday 24th September, 2019):

Fine day in paradise today; may get cloudy later on with low level snow flurries. Yesterday's storm delivered about 30-50mm or rainfall to the snow-pack, and only about 1cm of snow at its tail. A storm will redevelop tomorrow with snow to 600m forecast. No or poor freeze last night, so snow-pack will soften early today, some natural wet snow avalanche activity could be expected on radiated slopes today.

Previous Update (23/09/2019): Heavy rain and severe NW gales developing now! Snowfall to lower to 1500m today, and 800m over successive days! An isothermic snow-pack is expected to overload with moisture, a CONSIDERABLE avalanche risk will develop; valley floor run-outs are likely!

Previous Update (22/09/2019): Very poor freeze last night, climbers report snow-pack collapsed to knee-deep wet snow on many aspects at 1100hrs, after being a solid cramponable crust from early morning. Incoming NW storm slowly building for tomorrow (heavy rain / gales), snow forecast to low levels by Wednesday. See below for yesterday's report, it was much more marginal today!

Previous Update (21/09/2019): Very firm cramponable conditions on many routes in the very early AM, turning to break-through crust into soft snow by late AM / early PM, as freezing levels soar to well over 3000m. Reports of human triggered snow movements by PM in steeper terrain features (east aspects) - your route up may not be the same animal later in the day - self-arrests are difficult/impossible in the softer soup. Ridge cornicing continues to be a hazard on many exposed ridge-lines.

Previous Update (18/09/2019): A dense rain-crust, and frozen snow below has been providing a generally stable and firm snow-pack since yesterday. The freeze/thaw cycles continue. There has been some fresh snow fall about Main Range yesterday, providing a shallow powdery cover on the rain-crust. Strong northerly winds yesterday transported loose snow to south and east aspects, some fresh cornice building has occurred (these will be weak), and some pre-existing cornices have been back-filled with soft packed powder and have weak extensions; lee side gully snow could be soft, deep, and have instabilities. There is no indication we have a continuing avalanche issue from the storm (Moderate would suffice at most altitudes). Climbers should be very aware of cornicing on ridges, they are very large this year! In general climbing conditions have become "fair" in the past 24 hours, frozen approaches (north & west) and ridges (avoiding cornices) giving the best chance of success.

Previous Update (17/09/2019): Over 150mm of rainfall has fallen about the Main Range of the Park in the past 24 hours. Rain fell to 2000m for a greater part of this with lowering snowfalls after midnight, last night. The snow-pack is now heavily loaded with water, and a loose, wet avalanche cycle could remain active for several days, water will rot out the lower pack and glide-cracks are likely to develop; current activity appears to be snow-balling out of steep terrain features, and strong northerly winds transporting loose snow to lee aspects. Cornices have been heavily degraded or compromised in this storm, many have curled over, or stress fractures have opened along ridge crests; cornices have been very large this year (4m - 10m). Several days of freeze/thaw cycle are ahead, but this may only benefit the surface snow in terms of hardening it.

Previous Update (15/09/2019): A substantial number of loose, wet snow avalanche events occurred this morning from first sunlight. Class 1-3 events observed about the Main Range, with some events finding valley floor. This has been the most widespread avalanche activity seen all season! Also multiple wet snow avalanches reported in Cass Saddle area (Craigieburn) today. About 15-25cm of fresh snow has fallen above 1700m over past 72 hours. About 3cm fell in Village, but this has now all retracted to tree-line.. Further poor weather to redevelop tonight, with heavy rain from tomorrow afternoon and snowfalls to lower levels until Tuesday.

Previous Update (13/09/2019): Heavy rain to 1900m from yesterday 2200hrs, snow above, snow level to lower to 1200m today then 900m tomorrow. Seeing some wet snow avalanche activity to Class 1 - 2 out of southern aspect snow (loaded gullies mostly), fairly long glide paths when on unobstructed slopes.

Previous Update (9/09/2019): A series of three consecutive freezes over past days has given reasonably firm conditions on many routes today (not so great for skiers); though strong winds and strong radiation undone a lot of this after midday. Further cornice collapses noted today, and ridge-top glide cracks and vents are opening up on loaded ridges.

At least two more good freezes to come from tonight & tomorrow, so climbing conditions may be relatively good until Wednesday. Storm brewing on Thursday, with larger weather event on Friday.

Previous Update (8/09/2019): Climbers reported soft snow conditions on many approaches from yesterday. Cloudy today with snow showers and SE gales developing from afternoon. Cornices have been folding and collapsing over past couple of days, initiating loose wet avalanche releases to Class 1.

Previous Update (7/09/2019): Some further avalanche activity yesterday as small faces shed their snow (Class 1 to 1.5, once they collected gully snow below). Fine weather developing today, but a weak freeze overnight, expect the snow-pack to soften rapidly at all altitudes. MetService are saying snow to all levels for tomorrow (Sunday 8th).

Previous Update (5/09/2019): Rain to high level yesterday initiated some wet snow avalanche events to about Class 2. Further rainfall and lowering snowfall levels are expected today, and a continued cycle of wet/loose out of steeper terrain features.
