Avalanche Hazard Map – 2D

The map below is based on the advisory HERE

Avalanche Advisory Map



NO RATING
1 – LOW
2 – MODERATE
3 – CONSIDERABLE
4 – HIGH
5 – EXTREME

 

A zone with No Rating can mean that there is not enough snow for a rating, or that the last forecast has expired.

MAP DISCLAIMER – THIS IS NOT A MAP OF ACTUAL CONDITIONS
This map is for planning & reference purposes only. Actual observed conditions may be significantly different than the avalanche forecast map, and weather forecast. This map is not intended for navigational use in avalanche terrain. The avalanche forecast areas shown are cartographic representations for public safety outreach & education purposes only. This map is not produced by the US Forest Service. Although this map does not show any danger of natural & human-triggered avalanche activity outside the Mt Washington Avalanche Center’s forecast zones, additional avalanche terrain is located elsewhere across the White Mountain National Forest, and avalanches occur regularly outside the zones shown on this map.  Safe travel requires training and experience making your own snow stability assessments and terrain choices.

  1. The Mount Washington Avalanche Center has begun posting daily advisories for the 2018-19 season. The Avalanche Hazard forecast zones have changed dramatically. The map now shows a Presidential Range zone with an overall danger rating. This map is no substitute for reading the full advisory text, and the latest Observations posts.

  2. The Mount Washington Avalanche Center has issued the final daily advisories for the 2017-18 season. The Avalanche Hazard Map will show gray polygons with ‘NO RATING’ until November or December 2018.
