Dennis D’Amico

Dennis developed a passion for snow and weather while growing up in the not so mountainous Long Island, NY. He attended Cornell University in upstate New York and received a BS from the Atmospheric Science department. After a few seasons of dabbling in early backcountry ski adventures in New England & Eastern Canada, Dennis landed a weather forecasting position with the Seattle NWS in 2006. He was immediately drawn to the Northwest Avalanche Center’s unique DNA of mountain meteorology and snow science, and of course the easy access to the Olympics and Washington Cascades. Dennis was hired as an avalanche meteorologist for the Northwest Avalanche Center in 2012 and became the Forecast Director during the summer of 2019. He enjoys the challenge of forecasting weather and avalanche conditions during the season and working on and troubleshooting remote weather stations within the NWAC network throughout the year.

Working for NWAC has made Dennis appreciate all seasons, and in the forecasting offseason, you’ll find him relaxing and enjoying friends, family and his favorite pup.

Q&A With Dennis

How long have you been working for NWAC?

10 years (2012)

What brought you to work for NWAC?

I moved to Seattle to work for the National Weather Service in 2006, I had been angling to move my career out West since I graduated from college, spending all my time with friends in SLC or other western trips. Once I was there, I was really drawn to NWAC and how they blended mountain meteorology with avalanche forecasting and the rest is history!

Your favorite NWAC memory or the reason why you enjoy working for NWAC?

There are many, but there’s a distinct satisfaction when I play a role in delivering an accurate and helpful forecast. In my current role, I enjoy stepping back a bit more and setting up our expanded forecast team for success.

Any fun facts to share?

I worked for the Weather Channel of Canada (The Weather Network) in the early 2000’s right out of college. They would occasionally bring meteorologists up from the dungeons for on-air or taped interviews. A switcher inadvertently aired an out-take of mine where I dropped a four-letter word and played it on national television. There were a few complaints. These were the pre-YouTube days, sorry only 1 VHS copy exists!

Q&A with Dallas

What brought you to NWAC?

Honestly, Scott Schell [NWAC’s executive director]. When my wife and I moved to Washington I wanted to help out my new backcountry community. I began by submitting observations on NWAC’s public platform. One day I got a call from the staff at NWAC asking who I was and where I came from. Before I knew it, I was working as a professional observer for the center and teaching avalanche programs around the NW.

Why do you enjoy working for NWAC?

Simple, the people. The people that make up the backcountry community, the people that make up our volunteer staff, the people I work with. The people. Getting to see folks enjoy the mountains safely with their friends and family, it’s a true joy.

A favorite memory during your time with NWAC:

It’s not just one moment, but several. I love teaching avalanche awareness classes. I love seeing folks come into the evening rather nervous and a little scared of avalanches and the winter mountains. I love that by the end of the evening, they still have a healthy respect for avalanches, but they know they can go enjoy winter recreation by obtaining a few basic skills and reading the forecast. I love seeing them leave excited to explore the Cascades in the winter.

Q&A With Robert

How long have you been working for NWAC?

I’m up to a full 6 seasons working at NWAC, a period of rapid growth from 3 to 10 forecasters!

What brought you to this job?

I was originally an NWAC product user in graduate school, then as my research in mountain meteorology came into alignment with position openings at NWAC, I took my opportunity to get involved.

What have you enjoyed most?

I love working for NWAC because weather and avalanche forecasting in the dynamic PNW climate provides new challenges every day, so there’s rarely a dull day at work. It’s clear to me that my work matters to those around me who also enjoy the outdoors.

Any fun facts to share?

Off-season’s adventures in the global south have exposed me to some exotic ‘snacks,’ including charred spider legs, fried grasshoppers, and termites.

Q&A With Andy

2019  was Andy’s first season with NWAC.

What brought you to NWAC?

It started with quitting my job and just going skiing all the time. Eventually, I needed to make some money, so I tried to get jobs that were fun. That led me down the path of avalanche mitigation work via ski patrolling and highway forecasting which eventually landed me a new challenge of public forecasting at NWAC. 

Favorite part of the job?

I get to ski and work in wilderness areas while helping to inform people about avalanches, and to an extent the fragility and best practices of recreating in those wilderness areas. Sometimes it almost feels like I’m making a difference.

Lee Lazzara

Lee Lazzara is an Avalanche Specialist based in Bellingham whose primary responsibilities are the West Slopes North and Central zones. Although new to NWAC as an Avalanche Specialist, Lee was a Professional Observer for this area from 2015 through 2020.

Of all the aspects of snow, avalanches and backcountry travel in avalanche terrain, Lee finds observing and learning the nuances of the mountain environment the most fascinating. Why does it snow more on one side of the valley than the other? Why can snowpack change so drastically in a short distance across the same slope? How can minor differences in terrain choice have major implications for personal and group safety? Most importantly, how to communicate this information with others in a clear and consistent manner so they can use it in their own mountain travels?

Lee graduated from Seattle University in 1997 with a B.A. in English and quickly put his literary and writing skills to use skiing powder in Little Cottonwood Canyon. After nearly a decade of ski resort work including jobs, such as washing dishes in employee housing, shoveling snow, cleaning hot tubs, and not spilling wine on restaurant guests, he landed on the Snowbird Ski Patrol in 2005.  He began working as a mountain guide in the Cascades a few years later and gained IFMGA certification in 2013. 

Simon Trautman
