Everest Forecast 11 may
Until tomorrow high winds above 8000mr, from the 13th gradually decreasing. The wind stays between 25-35kt on the 13th and 14th. During the next days the wind at the higher levels will averagely be around 25kt.
So an the 13th the blowing snow eases, but than the airmass is unstable enough to trigger the daily snow shower(s). At this point those showers dont look too bad, the worst day being the 15th.

asiair7

Latest sat shot of South East Asia: stabilizing conditions over Nepal. Jet stream extends as far as the Himalayas, resulting in storm at the higher levels of the mountain (c) Satellite Image from Eumetsat 

Everest Forecast 10 may
On the 11th and the 12th there will be a severe storm above 8000mr. Average wind speeds of 50-60kt(=100-120km/hr) and gusting up to 70-75kt (=150km/hr). This storm wind start to decrease late on the 12th so on the 13th and the 14th wind on summit is averagely between 20-30kt, still quite windy. From the 15th wind further decreases (10-20kt) but than the airmass is getting more unstable and the risk for snow or snow showers increases. The worst day for snow/showers looks like being the 16th. But as you know, this is a trend which needs confirmation.

Latest Satellite Image of South East Asia shows improving conditions over Western Nepal, while the East is still covered with thick cloud. This improvement is expected to extend further to the East so conditions over Everest are about to improve as well. An the other hand we have to take in account severely increasing widspeeds above 8000mr. (c) Sat Pic from Eumetsat

jet1

Image shows the wind speed at the jet stream level over South East Asia. The lines that connect the points with the same wind speed, isotachs, are concentrated over North India and Nepal which means that for the next days (especially 10th and 11th) the wind at the highest levels of the mountain will reach values of about 100-120km/hr). (c) map from ‘Stormsurf’

Everest Forecast 07 may
Today and tomorrow (8th) still quite unstable with a significant risk for a few moderate snow showers during which the conditions may deteriorate significantly. From D2 conditions start to stabilize with an occasional shower on D2 and than for the rest of the period, most instability and cloud formation should remain below 6500mr, and precipitation is very unlikely. On the other hand from the 9th onwards, the wind above 8000mr will pick up severly with the windiest conditions on the 10th and the 11th. Probably an average wind of 40-50kt (=80-100km/hr) and gusts up to 120km/hr. From the 12th onwards that wind is slowly decreasing a little.

Latest Infra Red satellite shot showing South East Asia. Eastern parts of Nepal is subject to strong convective development which results in heavy snow showers on the slopes of the Himalaya’s. (c) Eumetsat

Everest Forecast 04 may
Confirmation of yesterday’s forecast
! Improving trend during second part of this period. Day 1, 2 and 3 are bad with poor conditions, heavy snow and snow showers. Day 4 is a day during which conditions are going to improve but still some showers possible. Than day 5, 6 and 7 look like pretty dry and only slightly unstable days. A negative aspect of this is the increasing wind speed in the higher levels of the mountain. See below for details.
