General Weather Forecast up to 13th September 2016
(I) Monsoon over Nepal is not over yet but has weakened, most notably, over far-west and mid-western regions (West of Dhaulagiri thru to far west).
(II) In the coming days(9-13Sept): resurgence/re-activation of Monsoon showers are to be noted most notably over Terai plains and mid mountains of Nepal but snow-showers (Sn-showers) in high mountains, most notably by 10 and 11Sept(aftns/evngs-nights).
(III) GFS Model based on 09Sept/00GMT: suggest much improved weather condition in the central and western regions of Nepal 18Sept after, except at few places of the High Himalayas. In the Eastern regions, however, occasional clouds growth and short periods of Thundershowers may occur, but short periods of Sn-showers. (This is preliminary indication only and hence may change with new data set on Numerical Weather Prediction)
Focus High Himalaya:
lo (1) Khumbu region (09-13sept): occasionally daily clouds, but thicker clouds especially during afternoon thru to night and short periods of Sn-shrs above 5400-5500m(approx). Weather significance on 10-12Sept(aftns/nights) with occasional Sn-showers. (2) Annapurna-Manaslu region (09-13Sept): occasionally daily clouds, but thicker clouds especially during afternoon thru to early night and short periods of Sn-shrs above 5300-5400m(approx) but most notably on 10-11Sept.
