Update 5/30/2007: Weather Outlook for summer Season 2007
SW Monsoon normally approaches northeast Pakistan during
first week of July and the monsoon currents mostly do not cross 35ºN due to
high mountain barriers.
Most of the northern parts of Pakistan (including all main
peaks i.e K2, NP, Broad Peaks, RP) are presently in the grip of a sub-tropical
jet which is prevailing abnormally over lower latitudes since last 10 days,
causing frequent evening clouds formation, poor visibility and snow over high
peaks. The temps are 4 to 6ºC below normal. The current conditions likely to
continue for another 8 to 10 days but giving short windows of one and two
The persistence of sub-tropical jet may disrupt/delay some
summits but relief for all main peaks is expected during second week of June.
The prevailing meteorological conditions and trends indicate
that monsoon ONSET over northeast Pakistan may be delay for one week to ten
days. So there is No Threat of monsoon activity for all main peaks but
frequent westerly waves may create problems at times during June.
At right now, neutral ENSO conditions are prevailing, weak
La-Nina is predicted during next 3 months. The monsoon is expected to behave
normally during first half (end of July) and it is to early to predict impact
of ENSO on monsoon. Regards. HANIF
