All of the spring months, March, April, and May, are notorious for lengthy storms and bad weather. Even when the cherry trees are blossoming down in the city, the slopes of the upper mountain can be extremely harsh. Any summit attempts should be made by teams with lots of experience, and not just climbing experience in general, but previous climbing experience on Mount Rainier. It's strongly recommended that climbers attempt the mountain for the first time during the regular summer season. Not having the correct warm clothes, a stove malfunction, running out of food and water, a ripped tent, being unable to navigate, and so many other hazards can become serious events this time of year. Make conservative decisions in the backcountry during this time. And, as always, check the forecast and avalanche report before venturing out on snowy slopes.
