****************************************************************** Everest forecast - From WNI and AdventureWeather.com By ExplorersWeb ******************************************************************* WNI Headline: Satellite imagery currently shows a great deal of clouds throughout Nepal and the ME area. Models concur that there is plenty of moisture in the ME area. Therefore, expect heavy snow showers around 7500m-7800m and below for the next few days. Showers will start to taper off by the start of next week. Dry weather is currently in the forecast for most of next week. The forecast for the winds has not changed much since the last forecast (around 5-12 m/s out of the W/NW). Monsoon is forecasted to advance well into the eastern and parts of the northern Bay of Bengal by the end of the period. Conditions do look good for the monsoon to advance into far south/southwest India soon after this forecasting period expires. Below 7500m - Look for the winds today to be around 5-8 m/s and increase a bit to around 10 m/s by the afternoon. Winds throughout the forecasting period are expected to be lighter in the morning (around 5 m/s) and increase slightly during the afternoon to evening (5-10 m/s). Heavy snow chances are high today and tomorrow with more widespread showers through the weekend (possibly lighter on Saturday evening and Sunday morning). A period of dry weather is becoming more likely next week. Above 7500m - Winds today will be a bit windy 7-13 m/s with the high end near the Summits. Winds should ease a bit this afternoon and increase slightly tomorrow (5-10 m/s). Look for the winds to be around 5-10 m/s throughout most of the period. At times winds will be less than 5 m/s but generally expect winds to be around 5-10 m/s. Winds could increase around the mid to late next week due to the possible incoming upper level trough. There is enough moisture today and through most of the weekend for snow around 7500m-7800m, but look for mainly cloud cover at higher elevations. A period of dry weather is currently in the forecast around the start to middle of next week above 7500m. Safe Climbing! Forecast for Mount Everest produced by Weathernews Americas Inc.
