Quiet Weekend, Storms Return Next Week

Summary

After delivering even more snow to the central resorts Wednesday night and Thursday, things began to quiet down to some degree across the Andes. We will get the break we need this weekend but storms are once again lined up in the South Pacific to keep the action going in the medium and long range.

Short Term Forecast

Many of the central resorts saw moderate to heavy snowfall over the last 48 hours, while the north began to clear out on Wednesday. Nevados de Chillan saw more than a meter of snow at the base during the last three days, while Corraclo received 1.5 meters in the last 72 hours, 40 cms of which fell overnight from Wednesday to Thursday, and another 25 cms reported this morning. 

This has been undoubtedly the best storm cycle of the season, producing the best conditions of the season. Further, I have seen some of the best photos and videos of the season as well. Some final storm totals numbers being reported by Powder Quest today are shown below.

Las Lenas: 3.5 - 4 m

Portillo: 2.4 m

Valle Nevado: 1.8 m

Cerro Catedral: 1.5 m

If you weren't able to get out during or after this memorable storm, don't worry too much, because more snow is on the way! Here a few shots from yesterday.

Forecast for Friday 8/25 - Sunday 8/27

The best news about this weekend? Temperatures should stay cold during this time, preserving the freshly fallen snow. The models show below-normal temperatures for this time of year through Sunday, with partly cloudy conditions most of the weekend. Ahead of the next storm, clouds will increase Sunday afternoon.

Forecast for Monday 8/28 - Thursday 8/31

Our next storm arrives Sunday night and lasts through most of Monday, with the heaviest snow in the central zone. Temperatures should remian cool enough for this to be an all snow event, except perhaps at the lowest elevation central resorts, where precipitation may begin as rain. This is looking like a 20 - 40 cm event on the high end in the central zone, at resorts like Pucon, Nevados de Chillan, Las Araucarias, and Corralco. In the north, Portillo should see 15 - 25 cms, with 8 - 16 cms elsewhere in that region. 

We'll have a very short break Monday night, before the next, even stronger system picks up Tuesday morning. This storm has the potential to deliver some big totals, with 40 - 80 cms possible in the central zone. This storm looks to be taking a more southerly track, limiting totals to 5 - 10 cms in the north. The heaviest snow should fall on Wednesday, with some light snow continuing through Thursday.

Extended Forecast

Outlook for Friday 9/1 - Tueasday 9/5

It looks like Friday and most of Saturday will be dry, but then another major storm arrives Saturday night. The models are not in agreement on the exact timing of this event or the temperatures, so we'll have to wait a few more days to provide additional details.
