We almost always get several winter-like snow storms in April and May. Treat each storm just like you would in winter. Avalanches can occur within the new snow typically from 1) low density layers deposited during the storm, 2) high precipitation intensity during a storm and 3) from wind slabs created during the storm.

It's easy to test the new snow as you travel by jumping on small test slopes to see if they avalanche or just dig down with your hand to see how well the new snow is bonding. Snow can change dramatically in both space and time so never let your guard down. Especially avoid any steep slope with recent wind deposits, which are almost always dangerous.

When cold, dry snow becomes wet for the first time, it almost always means wet sluffs (loose snow that fans outward as it descends) and occasional wet slabs. Also, slabs can involve old snow when melt water percolates through a layered, winter snowpack for the first time especially after 3 days of strong melting combined with no refreeze at night. Luckily, wet avalanches usually don't last forever because after a few days of percolating melt water, all the layers in the snow disappear and the snow becomes homogenous and dense, turning into a stable summer-like snowpack. Typically, this cycle of instability maturing into stability occurs first on the south facing slopes in early spring, then progresses to the east and west facing slopes in mid spring and finally by late spring, the upper elevation north facing slopes go through a wet avalanche cycle. Finally, glide avalanches occur regularly in spring as the entire snowpack slides slowly on the ground like a glacier until they suddenly release into a full-depth avalanche. These occur regularly on steep rock slabs and occasionally on steep grassy slopes. Notorious glide avalanche locations include places Stairs Gulch or the rock slabs in Broads Fork, which you should always avoid in spring. Avoid crossing under any slopes with telltale glide cracks in the snowpack. Remember they come down randomly, even at night.

The bottom line for wet avalanches:
Get out early and get home early. Get off of--and out from underneath--any slope approaching 35 degrees or steeper when the snow becomes wet enough to not support your weight. Warning signs may include:

• Roller balls (pinwheels) in new snow that is getting wet for the first time
• Natural or human triggered wet sluffs
• Small sluffs fanning out into larger slides, or running long distances
• Punchy or collapsing crusts
• Cornices breaking off
• Several days of strong melting combined with no refreeze at night

Any of these signs mean it's time to head home, or at least change to an aspect with cooler snow. Remember, even "smaller" slides can be dangerous in high-consequence terrain, such as above a terrain trap, trees, rocks, cliffs or a long, large avalanche path. Plan your trip to have a safe exit back to the car. (You can always click on the "I" button next to the avalanche problem icon for more information.)

As you travel in the mountains, keep a few things in mind:

• Avoid being on or below large ridge-top cornices. Overhanging cornices can break further back than expected and trigger avalanches on slopes below. Cornice falls are possible anytime, but are most likely during the heat of the day.
• Cold temperatures, hard snow and icy surfaces will cause potential "slide for life" conditions on steep slopes. Consider using crampons and an ice ax for mountaineering objectives.
• Continue to use safe travel protocols as you travel through avalanche terrain. One person at a time is the rule. Watch your partner from a safe spot. Everyone should have a beacon, shovel and probe and know how to use them.
