****************************************************************** Everest forecast - From WNI and AdventureWeather.com By ExplorersWeb ******************************************************************* WNI Headline: Latest satellite imagery shows a large area of clouds in the Bay of Bengal and northern Nepal. This is indicative of the Asiatic Monsoon becoming well established. The subtropical moisture is forecasted to create a good chance of showers throughout most of this week. Most of the showers will be below 7000m-7500m with the heaviest showers at lower elevations. Winds near the Summits look to be around 12-18 m/s throughout this forecasting period. Below 7500m - Good chance for showers (heavy at times) throughout most of this period. Heaviest showers will be around 6000m-6500m with occasional showers up to 7500m. The monsoon is well established in the Bay of Bengal and there is plenty of moisture to create heavy showers at times. Winds look to be around 5-8 m/s until the middle of the week when winds are forecasted to pick up to 6-10 m/s. Winds may increase at times during showers. Above 7500m - Winds look to be around 12-18 m/s at the Summits throughout this period. Today looks to be around 5-10 m/s above 7500m (11-14 m/s at the Summits). Slightly stronger winds are in the forecast around mid to late this week (10-15 m/s with winds 13-20 m/s at the Summits). Models have slightly changed and increased the moisture early in the period. Look for a chance for high clouds today through tomorrow, occasional on Wednesday, and Thursday. This will be the final Weathernews Americas Inc.
