As fronts approach the <a href="/facts/North_Cascades/jTedvXfT">North Cascades</a>, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of <a href="/facts/Rain/MLqcQEyx">rain</a> or <a href="/facts/Snowfall/HEFKcgIB">snowfall</a> onto the Cascades (<a href="/facts/Orographic_lift/eJHw5LFe">Orographic lift</a>). As a result, the west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> Due to its temperate climate and proximity to the Pacific Ocean, areas west of the Cascade Crest very rarely experience temperatures below 0 °F (−18 °C) or above 80 °F (27 °C).<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.<a class="footnote-ref" id="fnref:7" href="#fn:7"><sup>7</sup></a> Because of <a href="/facts/Oceanic_climate/xUD1y78o">maritime influence</a>, snow tends to be wet and heavy, resulting in high <a href="/facts/Avalanche/xm5qLRSC">avalanche</a> danger.<a class="footnote-ref" id="fnref:8" href="#fn:8"><sup>8</sup></a> </p> <h2 id="see-also">See also</h2> <ul> <li>Mountains portal</li></ul> <ul><li><a href="/facts/Mount_Persis/M9xAMhLf">Mount Persis</a></li> <li><a href="/facts/Geology_of_the_Pacific_Northwest/Yoha8TXP">Geology of the Pacific Northwest</a></li></ul> <h2 id="external-links">External links</h2> <ul><li>Weather forecast: <a href="https://www.yr.no/place/United_States/Washington/Mount_Index/">Mount Index</a></li> <li><a href="http://www.topoquest.com/map.php?lat=47.77455&lon=-121.58094&datum=nad83&zoom=4&map=auto&coord=d&mode=zoomin&size=l">"Mount Index"</a> (map).
