Significant impacts will be possible on snow & glaciers in the mountains during & after this heatwave! Water rushing thru snowpack can last for several days past peak heating, so these hazards can linger. Be prepared & hike with caution if you're heading out into next week. #wawx pic.twitter.com/5DnHKAXAhN
