Everest Forecast 16 may

Detailed wind expectation during summit attempt according to timing of ascent. The latest forecast confirms the previous one: there is a weather window to summit on the 17th but it closes very rapidly after 04-05utc. So same conditions same warnings as yesterday: the sooner the better.
Start on the 16th 2000NepTime (14utc) at C3-C4: during climb wind is average 5-10kt.
Estimated time to arrive at the summit: 06-0900NepTime (00-0300utc): wind on summit during that spell: WSW to WNW 10-15kt, after 10/11NepTime (04/05utc) again quickly increasing to 25kt.
To come down from summit C4-C3-C2: 15-20kt
Weatherwise: confirmation the airmass is unstable which results in the possiblity of a few showery outbreaks, but this should be very limited.

Estimated time to arrive at the summit: 06-0900NepTime (00-0300utc): wind on summit during that spell: WSW to WNW 10-15kt, after 08/10NepTime again increasing to 20-25kt.

Finally ‘our Guys on the Ice’ have some wind. Hopefully they can cover some distance during this windy spell because on the 14th wind dies off again.

Day1-13May N66/W39.9

Day3-15May

Advice: try to cover as much distance as u can right now. After the wind dies off on the 14th, weak for at least 24hr. Take care. M

Whispy high clouds point at high wind speeds at the jet stream level. Otherwise quite clear conditions over the Himalaya’s (c)Eumetsat

Everest Forecast 12 may
The 13th and the 14th the wind on the highest levels of the mountain is still strong (30-40kt=60-80km/hr). From the 15th till the 18th wind decreases to 10-20kt, after the 18th again becoming more than 35-40kt.
From the 15th the air is getting unstable enough to trigger a few snow shower. At this stage it looks like those showers will be rather limited and not too heavy.
So the 16 and the 17th look like a rather good weather window to go for.

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.

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.
